BESS Frequency Regulation: Engeri y’okugerageranya obunene bwa MW ne MWh

Okulungamya emirundi gya BESSekozesa amaanyi ga bbaatule ag’amangu, ag’enjuyi bbiri okutereeza obutakwatagana obw’ekiseera ekitono wakati w’okugabibwa n’obwetaavu bw’amasannyalaze. Frequency ya grid bw’egwa, enkola y’okutereka amaanyi ga bbaatule efulumya amaanyi agakola. Frequency bw’egenda erinnya, ecaajinga n’enyiga amaanyi. Omufuzi w’ekimera, .enkola y’okuddukanya amaanyi, enkola y’okukyusa amaanyi n’enkola y’okuddukanya bbaatule bigabana omulimu guno, era buli emu ku zo esobola okwetongodde ekkomo ku kuddamu.

Sipiidi kye kitundu eky’angu. BESS yonna ey’omulembe eya inverter-based esobola okukyusa amaanyi agakola mu sikonda oba wansi. Ekisalawo oba pulojekiti y’okulungamya frequency-efuna ssente tekinyuma nnyo: amasoboza mmeka mu butuufu agakozesebwa munda mu mbeera ekkirizibwa-ey-eddirisa ly’okucaajinga, okulwawo mmeka okutuula wakati wa mita ne inverter, oba siginiini y’okulungamya ewugula bbaatule okutuuka ku nkomerero emu ey’obuwanvu bwayo, n’okumanya oba ekyuma kiyita mu kugezesebwa kw’omukozi w’enkola nga tekunnabaawo ku kugezaako okusooka.

Ekitabo kino kitambula mu kuddamu kwennyini, okubala okunene n’ekyokulabirako ekikoleddwa mu bujjuvu, emitendera gy’okulemererwa egiraga mu kiseera ky’okutandika okukola.

BESS Frequency Regulation kye ki?

Grid frequency eraga real-time balance wakati w'omulembe n'okukozesa. Okwetaaga bwe kusukka omulembe, frequency egwa. Omulembe bwe gusukka obwetaavu, emirundi girinnya. Eky'obugagga ekitereeza frequency-kikyusa amaanyi gaakyo agakola okuyamba okuzzaawo bbalansi eyo.

BESS esobola okutambula mu njuyi zombi:

• Okuddamu kwa underfrequency:bbaatule efulumya amaanyi mu ggirita.
• Okuddamu kw’emirundi egisukkiridde:bbaatule ecaajinga n’enyiga amaanyi okuva mu ggirita.

Enkola za North America okutwalira awamu zitambulira ku 60 Hz emanyiddwa; enkola ezisinga ez’Abazungu, Bungereza n’endala nnyingi zitambulira ku 50 Hz. Ebipimo by’okukola, deadbands ne profiles ez’okuddamu ezeetaagisa biva mu koodi ya grid ekola n’omukozi w’enkola, so si kuva mu mugabi wa bbaatule.

Enjawulo emu esaana okutereezebwa nga bukyali, kubanga evuga buli kimu wansi: okulungamya frequency is aamaanyiservice, amaanyi aga backup yeamaanyiempeereza. Regulation esaba enkyukakyuka ez’amangu, entuufu, eziddiŋŋana mu maanyi ezipimiddwa mu sikonda n’eddakiika. Backup esaba ebifulumizibwa ebiwangaala ebipimiddwa mu ssaawa. BESS emu esobola okukola byombi, naye erina okupimibwa n'okufugibwa ku byombi - era emirimu gyombi gijja kuvuganya ku mbeera y'emu ey'omusango.

Lwaki Grid Frequency Ekyuka

Amasannyalaze gakozesebwa mu kiseera kye kimu we gakolebwa, kale obutakwatagana bulaga mangu nga okukyama kwa frequency. Ebisinga okuvaako mulimu okutambula kwa jenereta, ensobi mu kutambuza, omugugu omunene ogw’amakolero okukoleezebwa, enkyukakyuka ey’amangu mu bifulumizibwa ebizzibwa obuggya, ensobi mu kuteebereza, ekintu ekibaawo wakati w’omuyungiro oba omugugu omunene okukutuka. Enkula n’embiro z’obutakwatagana bivuga Rate of Change of Frequency, obuziba bwa frequency nadir n’obungi bw’amaanyi agatereeza enkola yeetaaga.

Jenereta ezikwatagana (synchronous generators) zitwala ekizito ekizitowa nga mu butonde kiziyiza enkyukakyuka ya frequency ey’amangu. Solar PV, ebyuma ebisinga ebikola empewo ne buli BESS biyungibwa nga biyita mu byuma by’amasannyalaze mu kifo ky’ekyo. Nga eby’obugagga ebisinziira ku inverter-bidda mu kifo ky’ekitundu ky’ekibinja ky’ebidduka ebikwatagana, obutakyukakyuka obw’obuzaale obutono bubaawo, era okuddamu okusinga kulina okuva mu bifuga inverter ebitegekeddwa obulungi n’ebitereke ebikoleddwa mu ndagaano. Enkola ya NERC ey’okwesigamizibwa ku...BPS-okuyungibwa okutereka amaanyi ga bbaatule n'ebyuma ebigattaekwata okuddamu kwa frequency okw’amangu ng’obusobozi BESS bw’erina okusobola okuwa, era n’egamba nti adjustable droop gains ne deadbands mu mode zombi ez’okucaajinga n’okufulumya, nga waliwo enkyukakyuka etaliimu buzibu wakati wazo.

Engeri BESS Frequency Regulation gy’ekola: Ekintu kimu, Ekyokubiri ku kyokubiri

Ebiwandiiko ebisinga byogera ku bulooka ezifuga. Kiba kya mugaso nnyo okugoberera ekintu kimu ekibaddewo ng’oyita mu kimera. Ensengeka y’ebiseera wansi kyakulabirako ekikoleddwa ku kyuma kya MW 10 ku nkola ya 50 Hz nga kiddamu engeri y’okugwa mu kitundu - ennamba zikiikirira, so si kulaga.

Ebintu bibiri mu lujegere olwo bisaana okuteekebwako, kubanga mu butuufu pulojekiti we ziremera.

Ekisooka, okukyama-ku-okukyusa amaanyi. A droop response etera okuwandiikibwa ngaokuddamu kw’amaanyi=okukyama kwa frequency × okufuga okuganyulwa. Oyo nkolagana ya ndowooza ey’okunnyonnyola ekirowoozo, so si nsengekera ya dizayini. Okussa mu nkola okwa nnamaddala kwetaaga enkola y’obubonero, okujuliza kwa frequency ey’erinnya, droop percentage ejuliziddwa ku defined power base, deadband, saturation ku rated power, ramp limit, ne hard clamps okuva ku SOC ne temperature. Mu kitundu kya Ssemazinga wa Bulaaya ekikwatagana, okugeza, ENTSO-E'senkola ku bintu bya FCRkyetaagisa nti okukola tekulwawo mu ngeri ya kicupuli era kutandika obutasukka sikonda bbiri oluvannyuma lw’omutendera gwa frequency, nti FCR enzijuvu eweebwa ku 200 mHz deviation, era nti deadband ne insensitivity nga bigattiddwa bisigala mu nga 10 mHz. Ezo parameters ennya - reference, droop, deadband, saturation - bye bino yinginiya w'okugezesa by'agenda okukebera mu butuufu.

Ekyokubiri, okugabanya obuyinza. Olukalala oluwanvu olw’ebintu ebifuga terubuulira musomi kintu kyonna ku ani avunaanyizibwa ng’okuddamu kulwawo. Mu nsengeka z’ebimera ezisinga obungi okwawukana kulabika bwe kuti:

• PCS:ramp rate, okulondoola obutuufu okumpi ne zero power, seamless charge-okudda -discharge enkyukakyuka, fault ride-okuyita. Latency wano etera okuba milisekondi era tetera kuba kizibu.
• Omufuzi w’ebimera / EMS:droop curve, deadband, SOC correction offset, okugabanya wakati w’empeereza eziteekeddwa, enneeyisa ku kufiirwa empuliziganya. Wano enkaayana za tuning ezisinga we zituukira.
• BMS:ekkomo ly’amaanyi aga chajingi n’okufuluma mu kaseera ako, okusinziira ku vvulovumenti y’obutoffaali, akasannyalazo, ebbugumu ne SOC. Kiyinza okusala mu kasirise obusobozi bwo obw’endagaano mu bitundu bibiri ku makya agannyogoga.

Ekiziyiza kya BMS kisaana okufaayo ku mutendera gwa dizayini okusinga mu kiseera ky’okugezesa. Obutoffaali bwa lithium bukkiriza akasannyalazo akatono ennyo aka chajingi ku bbugumu eri wansi, kale ekimera ekibeera ekikwatagana obulungi ku diguli 25 kiyinza obutasobola kutuusa kulungamya okukka wansi ku diguli −5 okutuusa ng’ebipapula bibuguma. Abakkirizibwaebbugumu ly’okukola erya bbaatulen’obusobozi bw’enkola y’ebbugumu okugikwata n’olwekyo kitundu kya nteekateeka ya frequency-service, so si afterthought.

Okulungamya Frequency vs Fast Frequency Response: Ensalo gy’etudde

Ebigambo ebikozesebwa emirundi tebirina mutindo mu nsi yonna, era ebintu eby’ettunzi tebikyusibwakyusibwa. Enkola z’Abazungu zikozesa Frequency Containment Reserve, automatic Frequency Restoration Reserve ne Frequency Restoration Reserve ey’omu ngalo; obutale bwa Nordic bwayawulamu FCR mu bintu ebya bulijjo-ebikola n’okutabangula. Obutale bwa North America bukozesa Primary Frequency Response, Regulation Up and Down, Fast Frequency Response, okutereka okukwatagana n’okutereka okw’akabenje. Emirimu gikola maapu ku buli emu mu ndowooza, nga wansi.

Ekiva mu dizayini kibeera butereevu. Ekintu eky’omulembe ogw’akabenje- tekitera kuyitibwa, kale amasoboza buli kukola matono naye obudde obwetaagisa obw’okutuusa buwanvu. Siginini y’okulungamya elondoolebwa obutasalako eyitibwa buli kiseera, kale okuyita waggulu kuli waggulu ate SOC drift ye bulabe obusinga. Battery y’emu eya MW 10 kyuma kya njawulo mu buli mbeera.

BESS Okufuga okulungamya emirundi, Latency ne Telemetry

Enzimba eya bulijjo ekola mita ya giridi → ekifuga ekimera oba EMS →enkola y’okukyusa amaanyi→ ebitereke bya bbaatule, nga ebiddibwamu bikulukuta okudda emabega nga biyita mu kkubo lye limu okutuuka ku SCADA. Olukalala lw'ebikwata ku lujegere olwo luwanvu, naye ebintu bisatu bye bisinga okulemererwa okugezaako okusooka-:

1. Okumaliriza-okutuuka-okumaliriza okusirika, epimiddwa okuva ku kutambula kwa frequency ku mita okutuuka ku maanyi ku kifo w’okuyungibwa - so si budde bwa PCS obw’okuddamu obujuliziddwa ku datasheet. Omuwendo gw’okulongoosa mita, obudde bw’okusengejja obutakyukakyuka, obudde bw’okulonda mu protocol n’obudde bw’enzirukanya y’omufuzi byonna bitumbibwa.
2. Ensengeka ya deadband ne droop, etera okuteekebwa mu bifo bisatu (PCS, plant controller, EMS) era nga yeetaaga okuteekebwa obutakyukakyuka mu kimu ddala ku byo.
3. Empuliziganya-enneeyisa y'okufiirwa, kubanga omukozi ajja kugigezesa. Oba ekyuma kikwata setpoint esembayo, ramps ku zero oba okugwa okudda ku local droop is a contractual choice, era kyetaaga okukwatagana n’amateeka g’akatale.

Emboozi eya bulijjo ey’okutandika okukola etambula bweti: PCS eddamu mu ms ezitasukka 200 ku katebe, naye mita esunsulwa ku Modbus TCP ku s 1, controller ekola enzirukanya ya ms 500 n’omusengejja wa s 1, era okuddamu kw’ekimera okupimiddwa kutuuka nga sikonda bbiri oluvannyuma lw’omutendera. Inverter teyaliko buzibu. Okutuuma erinnya ly'enkola - Modbus TCP, IEC 61850, DNP3, oba omukozi-enkolagana eyeetongodde - nakyo tekimala; pulojekiti erina okutereeza ebifo bya data, okulongoosa emiwendo, okufuga obuyinza n’enneeyisa y’okulemererwa mu buwandiike.

MW vs MWh ku kulungamya emirundi

Ensobi esinga okukolebwa mu kugerageranya obunene kwe kugula enkola ku kigero kyayo ekya MW. Ekipimo kya MW kiteekawo amaanyi ekyuma kye kisobola okukuba oba okunyiga mu kaseera kamu. Ekipimo kya MWh kiteekawo ebbanga ly’esobola okusigala ng’ekikola. Singa enjawulo eriwo wakati waebipimo by’amaanyi n’amasobozakikyali kifu, kitereeze nga tonnasoma kitundu kiddako, kubanga buli kimu wansi kibala kizimbibwa ku kyo.

Omukwano ogutandikirawo mwangu:

Amasoboza ageetaagisa=amaanyi g'okulungamya × obudde obwetaagisa obw'okutuusa

Era kumpi tekiba kya kuddamu. Nameplate MWh si MWh ekozesebwa, era ekituli kitera okuba ensonga bbiri oba okusingawo.

Engeri y'okugerageranya sayizi ya BESS okusobola okulungamya Frequency

Nga tonnaba kukola kintu kirala kyonna, funa ekitabo ky’akatale ekiriwo kati n’enkola y’okusooka okusunsulwa ku giridi yo n’ekintu kyo, era oggyemu: MW eyeetaagisa wansi, obudde bw’okuddamu, obudde obujjuvu-okutandika okukola, obudde obutono obw’okutuusa, obudde obutono obw’okuzzaawo, ebyetaago by’obutuufu n’okubeerawo, obunene obutono obw’okugula, amateeka g’okupima n’okupima essimu, n’enkola y’okugezesa yennyini. Tokoppa byetaago okuva mu nsi endala oba omukozi - eno ye ssaawa emu esinga obunene-omuwendo mu nkola yonna ey'okukola dizayini.

Omutendera 2: Teeka ekipimo ky’amaanyi okusinziira ku buli kkomo mu kkubo

Ensimbi eziterekeddwa mu ndagaano si zezokka ezisaba ku PCS. Obusobozi obw’okudda waggulu busobola okusibwako ekipimo ky’okufulumya kwa PCS, ekkomo ku kufulumya kwa BMS, ekkomo ku kufulumya emikutu gya giridi, okugereka kwa tulansifooma, amaanyi agaterekeddwa oba omugugu gw’ekifo. Obusobozi obugenda wansi busobola okuteekebwako ekkomo okusinziira ku PCS charge rating, BMS charge limit, grid import limit, obusobozi obusigaddewo oba site demand. Ku kivaamu eky’ekigerageranyo, endagiriro zombi zirina okubaawo ku busobozi obukoleddwa mu kiseera kye kimu - ekiziyiza ky’okusiba kitera okuba ekyo omuntu yenna kye yakoppa.

Omutendera 3: Kola amaanyi agakozesebwa, olwo okole emabega okutuuka ku nameplate

Wano ekyokulabirako ekikoleddwa we kifunira keep yaakyo.Ebibalo wansi kyakulabirako ekiraga enkola ey’okunnyonnyola; si specification era tezirina kukozesebwa ku project nga tewali mateeka ga operator yennyini ku bikozesebwa.

Ekyetaagisa:10 MW symmetric regulation, eddakiika 15 ez’okutuusa mu bujjuvu obutasalako mu buli ludda.

• Amasoboza ku kifo we bayungibwa, buli ludda: 10 MW × 0.25 h =2.5 MWh.
• Ekkubo ly’okufulumya (PCS, transformer, auxiliaries) ku roughly 94%: obutoffaali bulina okugabira nga2.66 MWh.
• Ekkubo lya chajingi ku bitundu nga 94%: okunyiga 2.5 MWh ku mita kiteeka ku2.35 MWhmu butoffaali.
• Total DC swing erina okutuula munda mu ddirisa erikkirizibwa:≈ 5.0 MWh- emirundi ebiri ennamba ya naive, kubanga ekintu ekikwatagana (symmetric product) kyetaaga amasoboza agaterekeddwaneekifo eky’omutwe ekyerere mu kiseera kye kimu.
• Eddirisa lya SOC erikkirizibwa erya 10–90% (80% likozesebwa): ekipande ky’erinnya ku ntandikwa y’obulamu Ekisinga oba ekyenkana 5.0 / 0.8 ≈6.3 MWh.
• Waranti ekakasa okusigala kw’obusobozi ebitundu 70% ku mwaka 10, nga tewali kwongera: nameplate ≈ 5.0 / (0.8 × 0.7) ≈8.9 MWh.

Kale ekyetaagisa "eddakiika 15-ku kyuma kya MW 10 kivaamu omugerageranyo gw'amasoboza-ku-amasoboza awalala wakati wa 0.63 ne 0.89 MWh buli MW - so si 0.25 okubala kw'omutwe kwe kutegeeza. Olwo okusalawo kwa yinginiya kuba kwa lwatu: gula nga 9 MWh ku lunaku olusooka, kkiriza capex era onyumirwe C-rate egonvu; oba okuzimba nga 6.5 MWh ne beeyama okwongera mu mwaka ogw’okutaano oba ogw’omukaaga. Bombi basobola okwewozaako. Ekitali kya kwewozaako kwe kujuliza 2.5 MWh. Add site-specific derating on top - sustained 40℃ambient ejja kusasula obusobozi obukozesebwa n'okusitula omugugu ogw'obuyambi, era omulimu oguvaamu kitundu kinene ku nsonga lwakiokulonda enkola y’okunyogozaye kusalawo kwa frequency-regulation okusinga okusalawo okw'ebyuma.

Omutendera 4: Londa eddirisa lya SOC mu bugenderevu

Ekigendererwa okumpi ne wakati w’olunyiriri olukkirizibwa kikuuma okukyukakyuka okw’enjuyi bbiri, era ku kintu ekikwatagana ekitera okuba entandikwa entuufu. Entandikwa, so si tteeka. Ekigendererwa ekituufu kikyuka n’ebyafaayo eby’okusosola mu bubonero, obutafaanagana mu mpeereza, amateeka g’okusasula amasoboza, kemiko, embeera za ggaranti, okukozesa okulala okutuumbiddwa n’obudde bw’ekintu ekisinga obubi-ekisuubirwa. Omufuzi alina okutereeza ekigendererwa mu ngeri ey’amaanyi; ebitundu ebinywevu ebikalu-ebiweereddwa enkoodi ku kutandika okukola y’ensibuko emanyiddwa ey’obutakola bulungi mu bulamu obw’oluvannyuma-.

Omutendera 5: Muteekemu okuvunda n’okuggwaako-ku-obulamu

Ekyuma ekituukiriza ekyetaagisa nga kipya kiyinza okukiremera mu mwaka ogw’omukaaga. Omuze gw’okugerageranya obunene gwetaaga okukaddiwa kwa kalenda, okukaddiwa kw’obugaali, okulaga ebbugumu, okuyita mu bisuubirwa, SOC eya wakati, C-omuwendo, ekkomo lya ggaranti, enteekateeka y’okugaziya ne - ekikulu - enkomerero etegeerekeka-ey’ekyetaagisa mu kukola emirimu gy’obulamu ekiragiddwa mu yuniti ze zimu n’endagaano.

Omutendera 6: Koppa okusinziira ku data entuufu

Okukoppa okusinziira ku representative frequency oba dispatch data ye nkola ya dizayini esinga okwesigika eriwo, naye okuteesa tekulina mugaso awatali parameters zaayo. Okunoonyereza okuyinza okwewozaako kulaga dataset ki ey’ebyafaayo eyakozesebwa era ku bbanga ki, ekiseera eky’okutwala sampuli, SOC eyasooka n’enkola y’okussa mu kifo, emisingi gy’okukkiriza, n’emisango egy’obuwulize. Ekitono eky’omugaso: waakiri emyezi kkumi n’ebiri egy’akabonero k’omukozi akafulumiziddwa ku kusalawo kwayo okuzaalibwa, kuddukanyizibwa okuva ku miwendo gya SOC egy’olubereberye egiwerako, ng’okulemererwa kunnyonnyolwa ng’ekiseera kyonna ekyuma we kitasobola kutuusa maanyi agakoleddwa mu ndagaano mu buli ludda. Average ya buli mwezi ejja kukweka ddala amadirisa amampi agakufiiriza ssente z’okubeerawo.

Enzirukanya ya SOC ey’okuddamu emirundi

Regulation etambuza battery okuva ku target yaayo. Omufuzi yeetaaga enkola ya recentring: slow charge oba discharge wakati w’ebintu ebibaawo, offset essiddwa ku regulation command, oba okusuubula mu katale k’amasoboza okuzzaawo ekifo we bakolera. Ekigendererwa kya symmetric - amasoboza agaterekeddwa agamala okufulumya nga frequency egwa, capacity empty emala okucaajinga nga erinnya.

Enkola y’okulemererwa ey’engeri ye saturation. Kirabika bwe kiti mu nkola: akabonero akalina akakwate akatono akataggwaawo katambula SOC waggulu okuyita mu misana; ku bitundu 85% ekimera tekikyayinza kukkiriza kulungamya kukka wansi mu bujjuvu; obubonero bw’omulimu gw’omukozi bukendeera, era olw’okuba obubonero bukozesebwa ku busobozi bwonna obukoleddwa mu ndagaano, okufiirwa kw’enyingiza kusinga nnyo amaanyi agazingirwamu. Tewali kyalemererwa. Tewali alamu yakubiddwa. Dizayini yamala kulowooza nti akabonero kaali ka maanyi-obutaliimu.

PJM, okugeza, egaba akabonero ka RegD ak’amangu ku mabbali ga siginiini ya RegA egenda empola, era obutaba na ludda lw’eby’obugagga eby’amangu bulina obukwakkulizo okusinga okukakasa - amateeka amakakafu n’enteekateeka ya siginiini eriwo kati bibeera muEkitabo kya PJM 12: Okutebenkeza emirimu, era data y’ebyafaayo ey’obubonero efulumizibwa. Gezesa okuteebereza okusinziira ku data eyo mu kifo ky’okugisikira. Mu Ssemazinga wa Bulaaya ekizibu kye kimu kikwatibwako mu bulambulukufu: ENTSO-E etwala bbaatule ng’ebiterekero by’amasoboza ebitono-era era yeetaaga endowooza y’okuddukanya SOC-ekola nga kwogasse n’ekiterekero ky’amasoboza ekitono ennyo, ekiwandiikiddwa nga tekunnabaawo, nga ekiseera ekitono eky’okukola kya ddakiika 30 eri yuniti ng’ezo mu mbeera ey’okulabula.

Okwonooneka kwa Battery Wansi w’Omulimu gw’Okulungamya

Okulungamya emirundi kitegeeza entambula entonotono nnyingi, ezitera okutambula. Okwambala okuvaamu kwesigamye ku maanyi gonna agayita mu masoboza, obuziba bwa buli cycle, omutindo gw’okusannyalala n’okufulumya, ebbugumu ly’obutoffaali, SOC eya wakati, obudde obumala okumpi n’ekkomo lya SOC, omulimu gw’okunyogoza, kemiko n’emyaka gya kalenda.

Enzirukanya z’okulungamya ezitali nnene zitera okuba ennyonjo buli yuniti y’okuyita okusinga okufuluma okw’obuziba okuddiŋŋana, naye ogwo gwe muze, so si kukakasa, era si nsonga ya kubuusa maaso kizibu: NREL’somulimu gw’okukoppa obulamu bw’obutoffaalieraga okufa kw’obusobozi okuvugibwa awamu ebbugumu, C-rate, obuziba bw’okufuluma n’embeera ya chajingi, nga enkola za kalenda-okukaddiwa zigenda mu maaso awatali kulowooza ku ngeri obutoffaali gye butambulamu. Battery ekuumibwa ku SOC enkulu n’ebbugumu eringi okukuuma upward regulation nga eriwo ekaddiwa ne ku lunaku olusirifu. Ensonda entuufu eza pulojekiti entongole ze bulamu bw’omugabi w’obutoffaali oba enkola yennyini n’akawaayiro akalaga ggaranti, nga bisomeddwa wamu.

Omuze gw’ebyobusuubuzi gulina okutwala omuwendo gw’okukyusa oba ogw’okwongera, okuyita mu ggaranti, okufiirwa mu lugendo lw’okudda-, amaanyi aganyogoza, obusobozi obutaliiwo, ebibonerezo by’okukola n’amasoboza ag’okuzzaawo SOC. Okuddamu amangu tekitegeeza nti ssente ntono ez’okukola.

Okugezesebwa nga tekunnabaawo n’okukola emirimu okusobola okulungamya emirundi

Empeereza ezisinga ez’emirundi egy’obusuubuzi zeetaaga okwolesebwa nga tebannaba kwetaba mu katale. Okugezesa kutera okwekenneenya okulwawo kw’okuddamu, omutindo gw’okulinnya, amaanyi agawangaala, obutuufu bw’okulondoola, obusobozi okudda waggulu n’okukka, okuddukanya SOC, telemetry, okubeerawo, okudda engulu oluvannyuma lw’okukola n’enneeyisa mu kiseera ky’okufiirwa empuliziganya.

Okunnyonnyola okumu, kubanga ensonga etabulwa bulijjo:Ekiragiro kya FERC No. 841kyetaagisa RTO ne ISO za Amerika okuteekawo enkola z’okwetabamu ezireka okutereka amasannyalaze okuwa obusobozi, amaanyi n’obuweereza obuyambi bwe busobola okuwa mu by’ekikugu, nga ekipimo kya sayizi ekitono ennyo tekisukka kW 100.

• Okutwala MWh ku lupapula lw’erinnya ng’amasoboza agaliwo.Eddirisa lya SOC, okuvunda, okufiirwa n’emirimu egyaterekeddwa mu ngeri entuufu bireka bulungi wansi wa kitundu kyayo ku mpeereza.
• Okwerabira okulungamya okukka wansi.Battery ejjudde tesobola kunyiga maanyi agasukkiridde. Obusobozi obwereere kintu kya bugagga.
• Nga tufudde nti akabonero ka maanyi-obutaliimu.Kigezese okusinziira ku biwandiiko by’ebyafaayo ebifulumiziddwa omukozi, so si ku nnyinnyonnyola y’ekintu.
• Okugula obudde bw’okuddamu okuva mu datasheet.Omuwendo ogugezeseddwa gwe kuddamu kw’ekimera okuva ku nkomerero-okutuuka ku nkomerero, era okupima nga kwogasse n’okulwawo kwa protocol kutera okukifuga.
• Okugezesa enyingiza awatali kukendeera.Enyingiza yonna ey’akatale si magoba ga pulojekiti oluvannyuma lw’okwambala, amaanyi agasasuza, okufiirwa, ebibonerezo n’okubeerawo biggyiddwako.

Olukalala lw’okukebera okugula ebintu mu kulungamya emirundi gya BESS

Omugaso gw’olukalala lw’okukebera kwe kumanya ebintu by’olina okwesenza. Okuzigatta mu bibinja bwe kityo:

Bino bitereeze nga RFQ - tennaba kunnyonnyola ekyuma

• Ensi egenderere, omukozi wa giridi n'ekintu eky'obuweereza ekya frequency-ekigere
• MW eyeetaagisa waggulu ne MW wansi, n’okumanya oba ekintu ekikolebwa kiri symmetric
• Obudde obwetaagisa obw'okutuusa n'obudde obujjuvu-okutandika okukola
• Ekkomo ku vvulovumenti y’okuyunga giridi, tulansifooma ne switchgear
• Enkola y’okugezesebwa nga tonnaba kuyita mu bisaanyizo n’okukakasa nti obeerawo
• Empeereza endala zonna ezigenda okusimbibwa, n’ensengeka yazo ezikulembeza

Bino bitambuza ebbeeyi mu bintu - bisalawo mu bumanyirivu

• MWh ekozesebwa n’ekifo ekikkirizibwa okukola emirimu gya SOC
• Entandikwa-ya-obulamu n'enkomerero-ekakasiddwa-obusobozi bw'obulamu
• PCS egenda mu maaso n’okugereka omugugu ogusukkiridde
• Battery chemistry, enkola y'okunyogoza ne design ambient
• Waranti ya bbaatule n’ekkomo ku kuyita mu bbaatule; enteekateeka y’okugaziya
• Fire-obukuumi n'ebyetaago bya koodi y'ekitundu

Leka omugabi ateese bino, olwo yeekenneenye

• EMS ne plant-controller omulimu gwawuddwamu, ne BMS ekkomo okukola lipoota
• SCADA protocol, data points, okutwala sampuli n’okukola dizayini ya telemetry
• Okukebera okuva ewala, sipeeya ne O&M scope

Bino bivaamu ebiragiro by’enkyukakyuka nga birekeddwa nga tebitegeerekeka bulungi

• Okuddamu-ennyonyola y'obudde - epimiddwa wa, era n'okugezesebwa kw'ani
• Empuliziganya-enneeyisa y'okufiirwa
• Ani nnannyini SOC recenting energy n'omuwendo gwayo
• Oba okubeerawo kupimibwa ku mutendera gw’ekkolero oba mu kifo

Okugonjoola ebikwata ku bintu bino bingi kye kireka abagaba ebintu okujuliza okusinziira ku mpeereza yennyini mu kifo ky’okugereka emiwendo ku genericenkola ya bbaatule eziteekeddwa mu bidomolan’okuzuula ekituli mu kiseera ky’okutandika okukola.

Ebibuuzo Ebitera Okubuuzibwa

BESS esobola okuddamu ku sipiidi etya ku kukyama kwa frequency?

PCS yennyini etera okuddamu mu bbanga eritakka wansi wa sikonda emu. Okuddamu kw’ekimera okukeberebwa kugenda mpola, kubanga omutindo gw’okulongoosa mita, okusengejja, okulonda kwa protocol n’obudde bw’enzirukanya y’omufuzi okugatta - sekondi bbiri okuva ku nkomerero okutuuka ku nkomerero kya bulijjo ku kyuma ekitali kituuniddwa. Ebyetaago by’ebintu byawukana: Amateeka ga ENTSO-E aga Continental Europe galagira okukola FCR okutandika obutasukka sikonda bbiri oluvannyuma lw’omutendera gwa frequency n’okutuuka ku kukola mu bujjuvu mu sikonda 30 ku 200 mHz deviation, ate obutale obulala bulambika profiles ez’enjawulo ennyo.

MWh mmeka eya frequency-regulation BESS yeetaaga?

Okusinga wala amaanyi × ebbanga. Ku kintu kya MW 10 ekikwatagana n’obwetaavu bw’okutuusa eddakiika 15-, okubalirira okw’okulaga waggulu kutuuka wakati wa MWh nga 6.3 ku ntandikwa y’obulamu ne MWh 8.9 bw’oba ​​oyagala okutuukiriza ekyetaagisa ku nkomerero y’obulamu awatali kwongera - okusinziira ku MWh 2.5 okuva mu nkola ya naive. Ekikubisaamu kiva mu kwetaaga amaanyi gombi agaterekeddwa n’ekifo ky’omutwe, eddirisa lya SOC eritali 100%, okufiirwa kw’okukyusa n’obusobozi okuggwaawo.

Mbeera ki eya chajingi ekozesebwa okulungamya frequency?

Ku mpeereza ya symmetric, okumpi ne wakati mu ddirisa erikkirizibwa, kale enjuyi zombi zisigala nga ziriwo. Ekigendererwa ekituufu kisaana okutambula n'okukyama kwa siginiini, obutafaanagana mu mpeereza, kemiko, embeera za ggaranti n'empeereza zonna ezitumbiddwa - mu ngeri ey'amaanyi, so si nga namba enzibu-eriko enkoodi.

Amasoboza agafuga frequency-tegaliimu ludda?

Si mu ngeri eyesigika. Siginini ezimu zikoleddwa okukwatagana okutuuka ku butabeera na ludda mu ddirisa ettono, era obutale obumu bufuula okukwatagana okwo okubeera n’obukwakkulizo. Persistent bias is the normal cause of SOC saturation, kale okuteebereza kulina okugezesebwa ku operator’s published historical signal nga tennakolebwa mu.

Okutereeza frequency kwonoona bbaatule?

Kibakaddiwa, ng’omulimu gwonna. Okuvuga obugaali okutono, okutera okutambula kutera okuba okugonvu buli MWh y’okuyita okusinga okufuluma mu buziba okuddiŋŋana, naye okufuluma kwonna, C-rate, ebbugumu ne SOC eya wakati byonna bivuga bifa, era okukaddiwa kwa kalenda kugenda mu maaso awatali kulowooza. Ekibuuzo ekikulu mu by’obusuubuzi si oba okwambala kubaawo wabula oba omulimu gusigala munda mu nvulopu ya warranty throughput.

BESS emu esobola okukola frequency regulation ne backup power?

Mu mubiri yee, era kye kyetaagisa ekya bulijjo muutility-pulojekiti z'amakolero ez'omutindo. Naye amaanyi g’okutereka agaterekeddwa tegafunibwa ku katale, era okutereka kukendeeza ku ddirisa lya SOC empeereza y’okulungamya ly’esobola okukozesa. Sayizi y’emirimu gyombi mu bulambulukufu, era osalewo nga bukyali ki ekivaamu mu kiseera ky’okulwanagana.

Okubumbako

BESS frequency regulation etebenkeza grid nga ecaajinga oba efulumya amangu era mu butuufu mu kwanukula supply-demand imbalance. Sipiidi, enkola bbiri n’okulondoola obutuufu birungi bya nnamaddala, era nabyo kye kitundu ekisinga okuba eky’angu mu pulojekiti okutuuka ku butuufu.

Ebitundu ebisalawo ekivaamu ge maanyi agakozesebwa munda mu ddirisa lya SOC, okusirika kw’enkomerero-okutuuka ku-enkomerero y’olujegere lw’okupima n’okufuga, enkola ya SOC ewona akabonero akasosola, enkola y’okuvunda ekyali etuukiriza endagaano mu mwaka ekkumi, ne dizayini efumbiddwa okusinziira ku kitabo ky’akatale ekigenda okukozesebwa mu butuufu mu kugezesebwa. Funa ensengeka y’omukozi eriwo kati, dduka okusiiga n’ebiteberezebwa ebiragiddwa n’emisingi gy’okukkiriza, era oteeke ennamba ku mabbali. Ekyo kye kifuula okulungamya emirundi okuva ku busobozi bwa BESS obw’awamu okudda mu pulojekiti eyeetegefu mu ndagaano-.
