Okukyusa emigugu n’okutereka amaanyi: Enkola n’emigaso

Ssente zo ez’ebikozesebwa zinyumya emboozi abaddukanya ebifo abasinga gye bandyagadde obutasoma. Waliwo wakati w’ebisale by’amasoboza n’ebisale by’obwetaavu watuula ennamba etalina kakwate na masannyalaze mmeka ge wakozesa ddala-ne buli kimu ekikwatagana nabyoddigwe wagikozesa. Oyo eddakiika 15 obwetaavu spike ku ssaawa 4:30 PM ku Lwokubiri? Yamala kuteekawo omuwendo gwo ogw’omwezi gwonna.

Okukyusa omugugu n’okutereka amaanyi ga bbaatule kikyusa ekizibu ekyo ku mutwe gwayo. Abasuubuzi bakozesa...enkola z’okutereka amaanyi ga bbaatuleokutereka amasannyalaze aga layisi off-peak n'okugafulumya nga emiwendo gya grid gituuse ku ntikko. Enjawulo etera okulabika ku cycle y’okusasula esooka ennyo. Tulaba ebifo eby’obusuubuzi nga bisika okukendeeza ku bitundu 15 ku 40 ku buli 100 mu nsaasaanya y’amasannyalaze n’ensengeka za BESS ezikoleddwa obulungi-n’ekibangirizi ky’okutereka ng’abaddukanya bayiga okulongoosa-okulongoosa enteekateeka zaabwe ez’okusasula/okufulumya mu myezi egisooka.

Okukyusa Omugugu Kye Kitegeeza mu Kutereka Amasoboza ga Battery

Okukyusa omugugu kutambuza enkozesa y’amasannyalaze okuva ku ssaawa ez’ebbeeyi ez’oku ntikko okudda ku madirisa agatali ga buseere agatali ga waggulu. Tokozesa maanyi matono-oddamu okusengeka nga gamaze okukozesebwa. Endowooza eno nnyangu-caajinga bbaatule ku $0.08/kWh ekiro, gifulumye ku $0.25/kWh mu kiseera ky’okudduka emisana-naye etabulwa n’obukodyo bubiri obukwatagana.Okusenya ku ntikkocaps your highest power draw okukendeeza ku demand charges.Okutereeza omuguguflattens your consumption profile mu lunaku lwonna. Okukyusa omugugu mu ngeri ey'enjawulo kuzannya obudde-bwa-ekituli ky'omuwendo gw'okukozesa: kilowatt-essaawa ze zimu, ssente ez'enjawulo ennyo.

Ebiseera-eby'emiwendo gy'okukozesa -bifuuse bya mutindo mu butale obusinga obungi obw'ebikozesebwa mu Amerika. Emiwendo gy’emisana n’akawungeezi gidduka emirundi ebiri oba esatu okusinga egy’ekiro-oluusi okusinga mu masaza nga California ne Massachusetts. Enkola y’okutereka bbaatule ecaajinga mu biseera by’amadirisa ago ag’ebbeeyi era efulumya amasannyalaze agaterekeddwa ng’emiwendo girinnye. Ebikwekweto tebikoma. Gridi elaba okunyigirizibwa okutono. Ebbago lino ligwa.

Engeri Tekinologiya wa BESS Gy’afuula Okukyusa Emigugu Okukola

Load shifting nga concept ebaddewo okuva mu myaka gya 1930. Naye okumala ebyafaayo ebyo ebisinga obungi, ebikozesebwa ebyaliwo eri bizinensi ssekinnoomu byali bitono nnyo-oba okukendeeza ku migugu ne bifiirwa ebivaamu, oba okuddukanya jenereta ya dizero n’ebisale byayo byonna eby’amafuta n’omukka ogufuluma. Ekikyusizza buli kimu ye kemiko wa bbaatule ya lithium iron phosphate (LFP) okukuba ku mutendera gw’ebyobusuubuzi.

Awo cost curve n’ekola ekintu kyayo. Battery packs zava ku doola 1,100/kWh mu 2010 okutuuka wansi wa doola 140/kWh mu 2023 (BloombergNEF). Ebiseera by’okusasula olw’...enkola z’okutereka amaanyi ga bbaatule ez’obusuubuziyatuuse mu myaka 3.5 okutuuka ku 5. Oyo ye nnamba eyafunira ba CFO okussaayo omwoyo.

Okukyusa emigugu mu by’obusuubuzi n’amakolero nga olina okutereka bbaatule

Si buli kifo nti kifuna amagoba ge gamu. Ebyenfuna byesigamye ku bintu bisatu: ensengeka yo ey’omuwendo, enkola yo ey’omugugu, n’obukyukakyuka bw’olina mu butuufu mu mirimu gy’okuteekawo enteekateeka.

Amakolero n’emirimu gy’amakolero

Wano eby’ensimbi we byasinze okukuba. Ku ssente z’amasannyalaze ez’amakolero eza bulijjo, ssente ezisasulwa mu bwetaavu zikola ebitundu 30 ku 50 ku buli 100 ku muwendo gwonna. Amakolero agaddukanya okukola ebyuma, okufulumya obuveera, okutereka mu nnyonta, oba okulongoosa emmere gonna goolekagana n’ekizibu kye kimu: obwetaavu bw’okulinnya mu ddakiika emu 15- mu kiseera ky’okukyusa ssifiiti oba ebyuma okutandika kuteekawo omusolo gw’ekiseera kyonna eky’okusasula. Essaawa emu embi eya kwata-essaawa, ennaku 30 ez’emiwendo egy’okulinnya.

Okutereeza kuno kukola nnyo okusinga bwe kiwulikika. Stagger compressor ne conveyor startups zo zonna zireme kusiba omulundi gumu. Kyusa HVAC preconditioning okudda ku ssaawa ez’ekiro ng’emiwendo giri wansi. Olwo leka BESS enyweze spike yonna ey’emisana esigadde. Ekifo ekikola omugugu ogw’oku ntikko ogwa MW 1.5 kiyinza okuteeka enkola ya bbaatule ya MWh emu ne kisenya kW 400–500 okuva ku sipii eyo. Ku $18/kW/omwezi mu bisale by’obwetaavu, ekyo kitegeeza $7,200–$9,000 ezikoona buli mwezi gumu-okusukka $86,000 buli mwaka nga tonnabala masannyalaze arbitrage. Tulabye ebimera nga bikuba payback mu myaka egitawera ena nga biriko profile ey’ekika ekyo, oluusi amangu nga state incentives ziri mu muzannyo.

Okutereka mu nnyonta kisaana okwogerwako mu ngeri ey’enjawulo. Pre-okunyogoza sitoowa ekiro ku $0.06–0.08/kWh, olwo leka ebbugumu ly’ekizimbe litambuze ebbugumu okuyita mu ddirisa ly’omuwendo gw’emisana ng’emiwendo gya giridi gikubisaamu emirundi esatu. Battery eno ekwata emigugu emirala egy’ekifo mu ssaawa ezo. Compressors zitambula bulungi. Omusolo gw’obwetaavu gukendeera. Y’emu ku nkola ezisinga obuyonjo kubanga ekizimbe kyennyini kifuuka ekitundu ku nteekateeka y’okutereka.

Kampusi z’ebyobusuubuzi n’ebizimbe bya ofiisi

Obutakwatagana kumpi busesa ku lupapula. Kampusi y’ebyobusuubuzi erimu amasannyalaze g’enjuba ku kasolya efulumya amaanyi ag’oku ntikko nga mu ttuntu-mu kiseera kyennyini ng’abantu batono, emigugu egy’okunyogoza gya kigero, ate ng’amasannyalaze ga buseere. Awatali kutereka, ekisukkiridde ekyo oba kifulumizibwa ebweru w’eggwanga ku miwendo gya net metering egitanyuma oba tewali we gagenda. BESS ekwata solar eyo ey’omu ttuntu, n’agikwata, n’agisika n’agizzaayo ebweru ku ssaawa 5:30 ez’ekiro nga buli omu azzeeyo, AC eriko cranking, era TOU rates zikuba daily max yaabwe. Kampusi emu gye twekenneenyezza yasengula ebitundu 25 ku 100 ku masannyalaze gonna agakozesebwa ne bagitwala mu madirisa ag’ebbeeyi entono era n’esala ku ssente ezisaasaanyizibwa ku masannyalaze buli mwaka enkumi n’enkumi za ddoola awatali kukendeeza ku nkozesa n’akatono. Pure rate arbitrage y’omutindo omulongoofu.

Empeereza za Grid ne Utility-Enkozesa za Scale

Ebitongole ebikozesa amasannyalaze nabyo bigula mu nkola eno-naddala mu bitundu ebizimbe by’emikutu gy’amasannyalaze gye bikaddiye oba ng’okuyingira kw’amasannyalaze agazzibwawo kusinga enkola y’obwetaavu.BESS erimu konteyinaokuteekebwa ku mutendera gw’okusaasaanya kuyinza okwongezaayo okulongoosa siteegi entono okwandibadde mu bukadde makumi. Ekitongole ky’ensi yonna ekivunaanyizibwa ku masannyalaze agazzibwawo kiteeka okukendeeza ku bwetaavu okuyinza okubaawo ku bitundu 20 ku buli 100 mu butale obuyingiza amasannyalaze agazzibwawo amangi.

Tekinologiya wa BESS n’okugerageranya obunene bw’okukozesa mu kukyusa emigugu

Kemiko ya bbaatule nsonga. Naye bwe kityo n’enkola y’okuddukanya amaanyi ng’etudde waggulu waayo, era oba ekipapula kyonna kirina sayizi entuufu ku nsengeka y’omugugu entuufu-si eyo ey’enzikiriziganya okuva ku ddeeke y’okutunda.

Ku bikozesebwa okugeraageranyaebika by’enkola y’okutereka amaanyi ne tekinologiya, LFP okusinga efuuse ekisookerwako ku nkola za buli lunaku-obugaali. Tewali cobalt kitegeeza enkola ezitebenkedde ez’okugabira abantu ebintu. Obulamu bw’enzirukanya buwangaala okusinga NMC ebitundu 40–60 ku buli 100 mu bifo eby’ensi entuufu-ebiyimiridde. Era safety margin-270℃thermal runaway threshold okusinziira ku NMC's ~150℃-kikola enjawulo eraga ku yinsuwa okuwandiika n'okukkiriza, naddala ku bifo ebiriraanye ebizimbe ebitudde.

Layer ya EMS ye savings we zifunira optimized. Enkola y’okuddukanya amaanyi etegekeddwa obulungi{1}}erondoola emiwendo gy’ebikozesebwa, data y’obudde, enkola y’omugugu gw’ekifo, n’embeera ya bbaatule ey’okucaajinga, n’etereeza enteekateeka y’okucaajinga/okufulumya mu kiseera ekituufu okukwata okusaasaana kw’emiwendo okuteekawo mu ngalo kwe kwandisubiddwa ddala. Enkola eziteebereza zisobola okutabula okutandika kw’ebyuma, okukwataganya okufuluma n’enkokola z’okuzaala enjuba, n’okutebenkeza enyingiza ya buli lunaku n’okuvunda kw’obutoffaali okw’ekiseera ekiwanvu-. Enjawulo wakati wa basic timer-based controller ne predictive EMS? Ebiseera ebisinga ebitundu 20–30 ku buli 100 mu kutereka buli mwaka okuva mu hardware y’emu.

Ensengeka za BESS eza bulijjo ez'okukyusakyusa emigugu

Sizing esinziira ku load profile, naye wuuno roughly engeri gye kimenyekamu:

Ebitono okutuuka ku bya wakati-sayizi eby’obusuubuzi (100–500 kWh):Enkola za kabineti ez’ebweru zikola bulungi wano. Polinovel'skabineti ey’ebweru BESSmu kW 60 / kWh 121 okutuuka ku kW 125 / kWh 241 ekwata ku ssaawa 2–4 ​​ez’okukendeeza ku bwetaavu ku bizimbe ebisinga eby’obusuubuzi. Zikwatagana mu bifo we basimbye mmotoka, obusolya, oba mu luggya lw’ebyuma, ziyungibwa ku bipande by’amasannyalaze ebiriwo nga tezirina nnyo nteekateeka ya kifo, era zisindika ne BMS ezigatta, okunyogoza amazzi, n’okuziyiza omuliro-tewali kulumwa mutwe mu kugatta batunzi bangi-ku kifo. Kabineti ya kWh 200 ng’ogasseeko inverter ya kW 100 esala kW 100 okuva ku spike y’ekizimbe ey’emisana. Singa demand charge yo eddukira $15/kW/month, ekyo single move kikekkereza $1,500/month.

Kampusi y’amakolero n’ennene (1 MWh+):Enkola ezirimu konteyina. Konteyina eya Polinovel eya ffuuti 20- eya mutindo erimu obusobozi bwa LFP 1–2 MWh ng’erina enkola y’okukyusa amaanyi ga kW 500 etambula buli lunaku okumala emyaka egisukka mu kkumi. Okuteekebwa mu nkola kwa konteyina eziwera-kutuuka ku MWh 5 n’okusingawo. Yuniti zino zijja nga zigatta mu bujjuvu-bbaatule, PCS, okuddukanya ebbugumu, okuziyiza omuliro, ne BMS byonna nga bigezesebwa mu kkolero nga tebinnasindikibwa. Okutandika okukola kitera okutwala wiiki, so si myezi gy’oyinza okumala ng’okwasaganya abatunzi ba bbaatule, inverter, ne controls ez’enjawulo.

Okugumira Amasoboza: Bonus Ezimbiddwa-Mu

BESS ekyusa omugugu-erina dda enkola y'amaanyi ag'okutereka. Mu kiseera ky’okuggwaako kw’omukutu, bbaatule ze zimu ezitera okulongoosa rate arbitrage zikuuma emirimu emikulu nga gikola-amalwaliro, ebifo eby’amawulire, okulongoosa amazzi, okukola obutasalako. Okwongera obusobozi bw'okutereka ku nkola eriwo kigula akatundu k'okuteeka mu nkola backup eyetongodde. Kigatte ne on-site solar era enkola esobola okuzinga ddala.

Kino si kye kisinga okuvaako ssente mu pulojekiti ezisinga obungi. Naye kikyusa okubala akabi naddala ku bifo ng’okuggwaako kw’essaawa nnya{1}}kugula ssente nnyingi okusinga enkola ya bbaatule yennyini.

Okukola Ensonga y'Ensimbi ku BESS Load Shifting

Simbula waggulu ssente zo ez’ebikozesebwa. Yawula emisolo gy’obwetaavu ku misolo gy’amasoboza. Funa enteekateeka yo ey'omuwendo gwa TOU era weetegereze okusaasaana wakati w'amadirisa g'omuwendo omunene-omuwendo omunene n'omuwendo omutono-. Olwo funa emikono gyo ku myezi 12 egya data ya mita ey’ekiseera-ebikozesebwa ebisinga biwa data ey’eddakiika 15 oba buli ssaawa okuyita mu mikutu gyabwe egy’oku yintaneeti.

Wano waliwo ekyokulabirako ekikoleddwa. Gamba nti oddukanya ekifo eky’amakolero ekya sq ft 200,000 mu Texas nga kiriko obwetaavu bwa MW 2 ku ntikko, ssente z’obwetaavu za doola 14/kW/omwezi, ate ddoola 0.12/kWh ezisaasaanyizibwa wakati w’emiwendo egy’oku ntikko n’egya ku ntikko. Oteeka ekyuma kya BESS ekirimu konteyina eya 1 MWh / 500 kW.

Enkola eno esenya kW 400 okuva ku ntikko yo eya buli mwezi. Ku $14/kW, ekyo kitegeeza $5,600/omwezi mu kutereka kw’omusolo gw’obwetaavu bwokka-$67,200 mu mwaka. Layer on energy arbitrage: okuvuga obugaali 1 MWh buli lunaku ku $0.12/kWh nga 90% round{12}}trip efficiency kivaamu nga $27,000/omwaka mu nnaku 250 ez’okukola. Okutereka ssente buli mwaka okugatta ku ttaka lya doola 94,000. Against a fully installed cost of $350,000–$400,000, otunuulidde okusasula emyaka 4 ku 4.5 nga tonnaba kusikiriza. Kozesa federal Investment Tax Credit era ekyo kikka okutuuka ku myaka nga 3.

Enteekateeka z’okuddamu obwetaavu layer waggulu. Ebitongole ebimu ebikozesebwa bisasula $50–$200/kW/year ku busobozi bwa bbaatule obuwandiisiddwa. Ku nkola ya kW 500, eyo eba ddoola endala 25,000–100,000 mu nsimbi eziyingira buli mwaka okusinziira ku katale n’ensengeka ya pulogulaamu.

Ku bibiina ebiteekateekapulojekiti ennene-okutereka amaanyi ga bbaatule, ebyenfuna bisigala bitereera. Ssente za bbaatule zikyagenda zikka. Enjawulo mu miwendo wakati w’entikko za buli lunaku n’amadirisa agasula ekiro zeeyongera mu butale obusinga obungi. Emitendera gyombi gisika ebiseera by’okusasula ebitono.

Engeri y'okutandika pulojekiti y'okukyusa emigugu nga olina BESS entuufu

1. Tandika ne data, so si byuma.Kola okubalirira kw’amasoboza, maapu y’enkozesa okusinziira ku ssaawa, era ozuule emigugu gye giyinza okutambula ddala nga tegitaataaganyizza kukola. Ebisinga okuvuganya kuliko HVAC preconditioning, okubugumya amazzi, EV fleet charging, n’okukola batch processing. Ebifo ebimu bikizuula nti ebitundu 30–40 ku buli 100 eby’obwetaavu bwabyo obw’okulinnya biva mu nkola eziyinza okwanguyirwa okukyuka okudda mu kiseera eky’enjawulo. Abalala basanga entikko zaabwe zisibye ku nteekateeka z’okufulumya, ekitegeeza nti bbaatule erina okunyiga ssifiiti enzijuvu.
2. Size okutuuka ku demand delta, so si total consumption.Ttiimu ya yinginiya eya Polinovel kino ekikola bulijjo-nga yeekenneenya data ya mita ey’ekiseera, okukola modeling demand charge ne arbitrage savings wansi w’ensengeka ez’enjawulo, n’okulaga kabineti entuufu oba enkola ya containerized ey’ekifo. Ekifo ekikozesa kWh 50,000/omwezi tekitegeeza nti kyetaagisa bbaatule ennene. Kiyinza okwetaaga kWh 200 zokka okusalako obwetaavu obuvuga ebitundu 35 ku 100 ku ssente. Ensobi ezisinga obunene zibaawo nga enkola zifuna obunene obusukkiridde okusinziira ku kWh yonna okusinga ku ntikko yennyini-okutuuka ku-off-entikko ekituli.
3. Kakasa nti ogoberera amateeka nga tonnagula.Kakasa nti enkola yo etambuza satifikeeti ya UL 9540 ne data y’okugezesa omuliro eya UL 9540A-bino bikosa butereevu ebiseera by’okukkiriza n’ebisaanyizo bya yinsuwa. Enkola za Polinovel zisindikibwa ne zombi, wamu n’obutoffaali bwa LFP, BMS ezigatta, okunyogoza amazzi, n’okuziyiza omuliro, byonna nga bigezesebwa mu kkolero- era nga byetegefu okutandika okukola mu wiiki ntono okuva lwe byaweebwa.
4. Optimize obutasalako oluvannyuma lw'okussaako.Olondoola omutindo gw’emirimu buli mwezi. Teekateeka amadirisa go aga charge/discharge nga enteekateeka z’emiwendo zikyuka buli sizoni ate nga n’emigugu gy’ebifo gikyuka. Pulojekiti ezisika amagoba agasinga obulungi ze zino omuntu gy’aba mu butuufu atunuulira dashboard-si ezo bbaatule gy’etuula ku auto era tewali akebera oba ensengeka za EMS zikyakwatagana n’ensengeka y’omuwendo eriwo kati.
