Enkola y’okutereka amaanyi ga bbaatule ekola etya?

Enkola y’okutereka amaanyi ga bbaatule (BESS) esasula okuva mu nsibuko y’amasannyalaze (giridi, enjuba, empewo, oba jenereta), etereka amasannyalaze ago munda mu butoffaali bwa bbaatule za lithium-ion ng’amasoboza ag’eddagala, era n’egafulumya ng’amaanyi ga AC agakozesebwa ng’ekifo kyetaaga. Entambula y’amasoboza eri nti:ensibuko y’amasannyalaze → enkola y’okukyusa amasannyalaze (PCS) → ebifo ebiteekebwamu bbaatule → omugugu oba giridi, ng’erina enkola y’okuddukanya bbaatule (BMS) ekuuma obutoffaali, enkola y’okuddukanya amaanyi (EMS) esalawo ddi lw’egenda okucaajinga n’okufulumya, n’okuddukanya ebbugumu n’okukuuma omuliro ng’ekuuma omutambi gwonna mu kkomo eritali lya bulabe. Ku pulojekiti z’ebyobusuubuzi, amakolero, n’ez’omugaso, okutegeera okutambula kuno kikulu kubanga kivuga butereevu okusalawo ku sayizi, okulonda PCS, topology y’okuyunga, n’ekiseera ky’okusasula.

Enkola y’okutereka amaanyi ga bbaatule mu butuufu kye ki

Enkola y’okutereka amaanyi ga bbaatule kintu kya masannyalaze ekijjuvu, so si bbaatule emu. Egatta obutoffaali bwa lithium-ion obuddamu okucaajinga n’ebyuma by’amasannyalaze eby’amaanyi, pulogulaamu ezifuga, enkola entonotono ez’obukuumi, n’ekisenge ekyetaagisa okukola obutasalako mu kifo oba siteegi entono entuufu. Obutoffaali butereka amaanyi; ebirala byonna biriwo olwo obutoffaali ne busobola okukola omulimu ogwo mu ngeri ey’obukuumi, enfunda n’enfunda, era ku kiragiro.

Pulojekiti ezisinga eziyimiridde ennaku zino zikozesa kemiko ya lithium iron phosphate (LFP). Okusinziira ku kitongole ky’amasannyalaze mu Amerika ekya...Ofiisi y’amasannyalazene grid-scale okulondoola okutereka ngaEkitongole ky’ensi yonna eky’amasannyalaze, lithium-ion efuuse kemiko esinga obunene ku busobozi bw’okutereka obupya obusibiddwa ku giridi-, nga LFP efuna omugabo olw’okukozesa okutambula okutambula olw’obutebenkevu bwayo obw’ebbugumu n’obulamu bwayo obw’enzirukanya empanvu ku ssente ez’ekigero.

BESS etera okukola omulimu gumu oba okusingawo ku gino wammanga:

• Ekyusa amaanyi g’enjuba oba empewo okuva ku ssaawa z’okukola okudda ku ssaawa z’okukozesa
• Ekendeeza ku ssente z’obwetaavu obw’oku ntikko nga efulumya mu biseera by’emigugu egy’oku ntikko
• Ewa amasannyalaze aga ‘backup’ mu kiseera ky’okuvaako amasannyalaze
• Etebenkeza microgrid egatta PV, dizero, n’omugugu
• Awa empeereza ya grid nga okulungamya frequency, okuwagira voltage, n’obusobozi bw’okutereka
• Ewagira okucaajinga kwa EV okw'amaanyi amangi-nga tewali kulongoosa bya bbeeyi

Enkola y’emirimu gya BESS: Entambula y’amasoboza mu bigambo ebitegeerekeka

Teebereza enkola nga payipu y'engeri emu olwo ekkubo bbiri-. Amaanyi gayingira okuva ku ludda lw’ensibuko; kifuna okukyusibwa, okuteekebwa mu mbeera, n’okutereka; oluvannyuma kifuna okukyusibwa okudda emabega ne kinyigirizibwa ebweru okutuuka ku migugu oba giridi. Controllers ssatu ziddukira mu parallel ekiseera kyonna.

Okusoma okutambula okuva ku kkono okudda ku ddyo:

• Ensibuko y’amaanyi(grid, PV array, wind turbine, generator) egaba amasannyalaze ga AC oba DC.
• PCS / ekikyusakyusa (inverter).etereeza AC mu DC okusobola okucaajinga, era n’akyusa DC mu AC mu kiseera ky’okufulumya, ate ng’etereeza vvulovumenti, frequency, n’amaanyi agakola.

Omutendera ogwo tegukyuka wakati wa kabineti ey’ebweru eya kWh 100 emabega w’ekkolero n’ekifo ekirimu konteyina ya MWh 5 ku siteegi entono. Ekikyuka ye kiraasi ya vvulovumenti, obunene bwa buli kitundu, n’engeri ekitongole gye kyekenneenya ennyo enkolagana.

Omutendera-by-Eddaala: Ebibaawo mu kiseera ky'okusasula, okutereka, n'okufulumya

Omutendera 1. Okucaajinga - Okuleeta Amasoboza Mu

Okucaajinga kutandika nga EMS elaba ensonga lwaki ecaajinga: amasannyalaze ga buseere, PV array ekola ekisusse, oba bbaatule eri wansi w’embeera y’okucaajinga gy’egenderera. PCS esika AC okuva mu nsibuko, n’agitereeza okutuuka ku DC, n’agisika mu ludda lwa bbaatule ku vvulovumenti ne kasasiro ebifugibwa. Singa ensibuko eba DC (ensengekera y’enjuba eyungiddwa ku DC-, okugeza), emiguwa gya PV gisobola okuliisa bbaasi ya DC butereevu okuyita mu kikyusa DC/DC, okwewala lawundi emu ey’okukyusa AC/DC.

Nga amasannyalaze gakulukuta, BMS essa mu nkola ekkomo ddene. Singa cell yonna esemberera voltage threshold yaayo eya waggulu, singa module eddukira nga ebuguma, oba singa cell balancing egwa emabega, BMS ekendeeza current oba eyimiriza okucaajinga. Kino kye kikuuma enkola ya LFP nga terina buzibu mu nkumi n’enkumi z’enzirukanya - si kemiko yokka, wabula kemiko nga kwogasse n’okulondoola okunywevu.

Ekitegeeza mu dizayini:enkola y’okusasula etera okuba nga pulojekiti zikulukuta omuwendo. Ekkolero eribuusa amaaso ebiseera-by-ebisale by'okukozesa n'ebisale mu ssaawa ez'okukola ennyo lizimbye bbaatule ey'ebbeeyi mu kifo ky'okukola amagoba. Ensonga ya EMS, so si datasheet y’obutoffaali, y’esalawo ekivaamu.

Eddaala 2. Okutereka - Okukwata Amasoboza Nga Totyoboola By’obugagga

Obusannyalazo bwe bumala okuyingira, ion za lithium zituula ku ludda lwa anode, nga zeetegefu okusenguka okudda emabega ng’omugugu guyise. Okukwata state si passive wadde. BMS egenda mu maaso n’okutebenkeza obutoffaali ku bulala, kubanga mu rack empanvu obutoffaali obusinga obunafu buteekawo obusobozi obukozesebwa. Okuwuguka kw’obutoffaali-ku-okuwuguka kw’obutoffaali wadde amakumi matono aga milivolti kuyinza okusenya amasoboza agakozesebwa.

Ebbugumu ye nkyukakyuka endala esirifu. Obutoffaali bwa lithium-ion buvunda mangu ku bbugumu erya waggulu ate ne bufiirwa obusobozi ku bbugumu erya wansi ennyo. Okunyogoza okw’amazzi okusinga kuzze mu kifo kya dizayini z’empewo eziwalirizibwa-mu C&I n’ebintu ebikozesebwa kubanga kukwata obutoffaali munda mu bbandi y’ebbugumu erifunda, nga bino byombi bikuuma obulamu bw’enzirukanya n’okuwagira emiwendo gya C- egy’oku ntikko. Okusobola okulaba mu bujjuvu ebyo ebituula munda mu nkola eya bulijjo, laba Polinovel’s breakdown of theebitundu munaana ebikulu eby’enkola y’okutereka amaanyi ga bbaatule.

Ekitegeeza mu dizayini:obusobozi obukozesebwa si busobozi bwa nameplate. BESS ya 1 MWh ku buziba bwa 90% obw’okufulumya n’obulungi bwa 92% okudda n’okudda-etuusa okumpi ne kWh 830 buli cycle ku AC terminal. Bulijjo sayizi okusinziira ku maanyi agakozesebwa, so si nameplate.

Eddaala 3. Okufulumya - Okusika Amasoboza Okufuluma

EMS bw’eyita okufuluma, bbaatule esindika DC ebweru eri PCS, ekigikyusa n’efuuka AC ekwatagana ne giridi (oba bbaasi ya microgrid eri ku kizinga) mu vvulovumenti, frequency, ne phase. Okufulumya kuyinza okutandikibwawo akabonero k’ebbeeyi, omuwendo gw’omusolo ogw’obwetaavu-, ebbula lya PV akawungeezi, oba okuvaako kw’omukutu. Mu mbeera ya grid-tied, PCS egoberera grid; mu mbeera y’ekizinga, PCS ekola ekisengejjero kyennyini.

Ebbanga enkola eno ly’esobola okufulumya lisinziira ku nnamba ssatu abaguzi abasinga ze bazitowa: obusobozi obukozesebwa (kWh), ekipimo ky’amaanyi agagenda mu maaso (kW), n’omugugu gwennyini. Enkola ya kW 500 / kWh 1,000 esobola okukwata kW 500 okumala essaawa nga 1.8 ku 1.9 oluvannyuma lw’okufiirwa - so si ssaawa bbiri ezijjuvu ezitegeezebwa okugabanya okwangu.

Abafuga Abasatu: BMS, PCS, ne EMS

BMS - Omukuumi w'Eddaala ly'Obutoffaali-

Enkola y’okuddukanya bbaatule egera vvulovumenti y’obutoffaali ne modulo, akasannyalazo, n’ebbugumu mu kiseera ekituufu, ebala embeera ya chajingi (SOC) n’embeera y’obulamu (SOH), egerageranya obutoffaali, era n’ekola ebikwatagana (contactors) singa wabaawo ekikyamu. Mu BESS etakyukakyuka, omutindo gwa BMS gulaga oluvannyuma, so si ku kutandika okukola - gulaga mu mwaka ogwokusatu nga rack emu ekyakwatagana n’endala.

Ebintu BMS ey’amaanyi by’ekwata nti embalirira BMS etera okubuuka: enkola ya passive vs active balancing, granular temperature mapping, okulondoola insulation ku ludda lwa DC, n’empuliziganya ennyonjo ne PCS zombi n’ekifo SCADA.

PCS - Ebyuma by'amasannyalaze eby'amaanyi

Enkola y’okukyusa amaanyi ekyusa AC okudda mu DC n’emabega, efuga ensonga y’amaanyi, ewagira emitendera egy’okukola giridi- oba giridi-okugoberera, era etera okuba ekitundu ky’ebyuma ekimu ekisinga ebbeeyi oluvannyuma lw’obutoffaali. Ekipimo ky’amaanyi ga PCS (kW) tekikwatagana na maanyi ga bbaatule (kWh) - osobola okugatta PCS ya kW 250 n’ekintu kyonna okuva ku pack ya kWh 250 ey’amangu-obugaali okutuuka ku pack ya MWh 2 obuwanvu-obuwanvu. Okusobola okwanjula ku biri munda mu bulooka eno n’engeri gy’eyogera n’enkola yonna, Polinovel ekuuma omunnyonnyola eyeewaddeyo ku...enkola y’okukyusa amaanyi mu BESS.

Ku nkola eyungiddwa ku grid-mu North America, PCS erina okugobereraIEEE 1547, omutindo gw’okuyungagana kw’eby’obugagga by’amasoboza ebigabanyizibwa. Kino tekiteesebwako ku pulojekiti yonna ey'omugaso-sibiddwa era kibumba okuvuga-okuyita, okulungamya vvulovumenti, n'enneeyisa elwanyisa-okuzinga.

EMS - Omutendera gw'okusalawo

Enkola y’okuddukanya amaanyi bwe bwongo. Esoma emisolo, okuteebereza emigugu, okuteebereza kwa PV, SOC, embeera ya giridi, n’emiwendo gy’okusasula obwetaavu-, olwo n’efulumya ebifo ebiteekeddwawo eri PCS. EMS erongooseddwa obulungi-ye eyawula BESS esasula mu myaka etaano okuva ku esasula mu myaka mwenda. Singa ebisale by’obwetaavu bye bisinga okuvuga omuwendo mu kifo, EMS erina okukulembeza okusenya ku ntikko mu kiseera-of-okukozesa arbitrage - enkola zombi zitera okusika mu makubo ag’enjawulo ku lunaku lwe lumu. Okumanya ebisingawo ku ngeri layeri y'okufuga gy'ekola okulonda okwo, laba okulambika kuno okwa...EMS mu nkola z’okutereka amaanyi ga bbaatule.

BESS Working Modes mu kutunula

Engeri BESS gy'ekola ne Solar: AC-Eyungiddwa vs DC-Eyungiddwa

BESS bw’egattibwa ne PV, ekibuuzo kiri nti ensengekera zombi zikwatagana mu masannyalaze. AC coupling ezigatta ku bbaasi ya AC ng’eyita mu inverters ez’enjawulo. DC coupling ezigatta ku ludda lwa DC okuyita mu shared inverter oba DC/DC converter, nga PCS emu ekwata AC conversion.

Okusuubula-okutera kuba ku retrofit vs new build. AC-coupled designs ze nkola entuufu okulonda okwongera okutereka ku kyuma ky'enjuba ekyatandikibwa edda - okuuma PV inverter eriwo n'osiba enkola ya bbaatule ku. DC-coupled designs mu bujjuvu zikola bulungi nnyo ku pulojekiti empya ez’okutereka enjuba-plus- kubanga zeewala olugendo lumu olwa DC→AC→DC round-ng’amasoboza ga PV gagenda butereevu mu bbaatule. Era zisobozesa PV okusukkiridde obunene bw’ogeraageranya ne inverter, ne zikwata amasoboza agaandisaliddwa. Okusobola okugeraageranya eby'ekikugu ku ludda-ku ludda, laba ekiwandiiko kya Polinovel kuAC-coupled vs DC-coupled bbaatule okutereka.

Engeri BESS gy’ekola mu mbeera z’ebyobusuubuzi n’amakolero

Abaguzi ba C&I batera okuba n’ebizibu bisatu bye bafaako mu butuufu: ssente z’amasannyalaze nnyingi nnyo, okuvaako kw’amasannyalaze kwandiyimiriza okufulumya, ate nga n’ensengekera y’enjuba tesasula mangu nga bwe kyali kisuubirwa. C&I BESS ekoleddwa obulungi-esobola okukola ku byonna ebisatu, naye tebitera kuba na nsengeka y'emu.

Singa ebisale by’obwetaavu bye bisinga okulumwa, enkola erina okuba nga ya sayizi ya kW ey’oku ntikko okusinga kWh yonna. Paaka ya kW 500 / kWh 500 ekuba eddirisa ly’obwetaavu-charge mu ngeri ey’obukambwe esobola okusinga pack ya kW 250 / kWh 1,000 mu kifo kye kimu. Singa backup ye nsonga enkulu, okubala kukyusa - kWh kwe kufuga, era olukalala lw'omugugu omukulu-lusalawo ekipimo ky'amaanyi. Ku pulojekiti za C&I ezisinga obungi, ensonga ya ffoomu ya kabineti erimu konteyina oba ey’ebweru-ye nkola ey’okulonda; Polinovel'seby’okutereka amaanyi mu by’obusuubuzi n’amakoleroera nga yeewaddeyokabineti ey’ebweru BESSlayini ezibikka obunene obwa bulijjo okuva ku kWh nga 100 okutuuka ku MWh eziwerako.

Ensobi emu eya bulijjo esaanira okuteekebwako bendera: BESS ya 1 MWh tekitegeeza ssaawa emu oba bbiri ez’okutereka mu ngeri ey’otoma. Obusobozi obukozesebwa, ekkomo ly’obuziba bw’okufulumya eriteekebwawo ebiragiro bya ggaranti, emigugu gy’ebiwuka okuva mu kunyogoga, n’omugugu omukulu ennyo-simbula chip zonna mu kiseera ky’okudduka. Bulijjo kola emabega okuva ku lukalala lw'emigugu, so si mu maaso okuva ku lupapula lw'erinnya.

Engeri Utility-Scale BESS gy'ekola

Fizikisi zifaanagana n’enkola ya C&I - charge, store, discharge - naye envulopu ya yinginiya egaziwa nnyo. Pulojekiti ez’omugaso ziyungibwa ku vvulovumenti eya wakati (mu ngeri entuufu kV 12 ku 35 mu North America) era zeetaaga tulansifooma ezigenda waggulu, MV switchgear, protection relays, SCADA integration, n’okugezesa okugoberera okusinziira ku mutindo gw’okuyungibwa ogukwatagana.

Ensimbi eziyingira mu mirimu zitera okuva mu kutabula kwa arbitrage y’amasoboza, okusasula obusobozi, n’empeereza ez’okuyambako nga okulungamya frequency n’okutereka emirimu. Ekitongole kya Amerika ekya National Renewable Energy Laboratory kiwa okwekenneenya okunene okuggule ku...grid-okutereka amaanyi ku mutindon’engeri emigogo gino egy’enyingiza gye gigatta mu nsengeka z’akatale ez’enjawulo.

Obukuumi bw’omuliro nabwo bufugibwa nnyo ku mutendera guno. Ebipya ebiteekebwa mu bitundu bingi ebya Amerika birina okutuukirizaNFPA 855, omutindo gw’okuteeka enkola y’okutereka amaanyi agatali gakyukakyuka, ku mabbali g’olukalala lw’ebintu ebya UL 9540. Dizayini z’ebintu ebikozesebwa mu konteyina zizimbibwa okwetoloola ebyetaago bino okuva ku lunaku olusooka okusinga okuziddamu okuzimbibwa oluvannyuma. Polinovel'sutility-okugonjoola ebimera ku mutenderaneBESS erimu ebidomolafamire y'ebintu bitegekeddwa ku mbeera zino ez'okugoberera.

Ekisalawo Obulung’amu bwa BESS n’Obulamu bw’Empeereza

Obulung’amu bw’okutambula okwetooloola-lithium-ion BESS ekoleddwa obulungi etuula mu 85–92% ku terminal ya AC, ng’ebisigadde bifiiriddwa okukyusa, emigugu egy’obuyambi (okusinga okunyogoza), n’okwefulumya-. Obulamu bw’obuweereza okutwalira awamu bulambikibwa mu nsengekera okutuuka ku bitundu 70 oba 80% ku busobozi obw’olubereberye, era ku nkola za LFP eziyimiridde butera okupimibwa mu nsengekera ya 6,000–10,000 okusinziira ku buziba bw’okufulumya n’ebbugumu ly’okukola.

Ensonga ezitambuza ennamba ezo mu nnimiro:

• Ebbugumu ly’okukola.Okukola okuwangaala waggulu wa roughly 35℃noticeably okwanguya capacity fade. Okunyogoza amazzi n’okusiiga ekisiikirize ekituufu mu kifo bikola enjawulo epimibwa mu bbanga ery’emyaka 10.
• C-omuwendo.Okuvuga akatoffaali ku 1C buli lunaku kakaddiwa amangu okusinga okukavuga ku 0.5C. Ku nkola ez'ekiseera ekiwanvu-, okupima obunene ku muwendo gwa C- ogwa wansi kutera kuba kwa buseere okusinga okukyusa obutoffaali nga bukyali.
• Obuziba bw’eddirisa erifulumya amazzi.Okukola wakati wa 10% ne 90% SOC kigonvu ku butoffaali okusinga 0–100%, ku muwendo gw’amasoboza amatono agakozesebwa.
• Obulung’amu bwa PCS.PCS ekola obulungi ebitundu 98%- okusinziira ku 95%-ekola bulungi, ekyukakyuka ya bubonero 3-ku buli kikumi-ku buli kWh etambula mu nkola - ebintu mu bulamu obw’emyaka 15.
• Enkola ya EMS.Aggressive arbitrage with deep daily cycles yambala obutoffaali amangu okusinga okusenya ku ntikko okutono. Enkola entuufu ye nfuna yonna esukka ku nsaasaanya yaayo ey’okusaanyizibwawo.

Engeri y'okulaga BESS: Amawulire Omukubi w'ebifaananyi Gye Yeetaaga Mu butuufu

Pulojekiti za BESS ezisinga ezitali nnungi zitandika n'okusaba okutali kwa maanyi ("twagala kWh 500") ne zimaliriza nga zisukka- oba wansi-sayizi. Okufuna dizayini ennyonjo n'okujuliza okuyinza okwewozaako, gabana bino wammanga nga tewali muntu yenna akuba kifaananyi kya layini emu-:
