Abathuthukisi bephrojekthi nabaphathi bezikhungo abahlola ukugcinwa kwamandla ukuze basetshenziswe ngaphandle babhekana nesethi eqhubekayo yezinselele: amazinga okushisa aphakeme, izithiyo zesikhala, kanye nesidingo sokusebenza okuthembekile kwesikhathi eside. Amasistimu ajwayelekile okupholisa umoya ngokuvamile athwala kanzima ukuze alondoloze umthamo olinganiselwe phakathi namagagasi okushisa ehlobo noma adinga ukucaciswa okudlulele okwenza kube nzima ukubeka indawo. Kuwo wonke umkhakha, sibona ushintsho olusheshayo oluya kuzixazululo ze-BESS zokupholisa uketshezi zalezi zinhlelo zokusebenza. E-Wenergy, isistimu yethu yokugcina amandla okupholisa uketshezi engu-261kWh iyisibonelo sokuthi kungani lobu buchwepheshe buzuza okuthandwa kakhulu phakathi kwamaqembu ephrojekthi yezohwebo nezimboni. Isebenza kahle ngo-90% ukuya nokubuya, amandla okuphendula asheshayo angu-125kW, nokusebenza okuthembekile kusukela ku-minus 30 kuya ku-555 degrees Celsius, uketshezi olupholile BESS ukulungiselelwa ukubhekana nezidingo ezithile zokufakwa kwangaphandle. Ngezansi, sihlola izici eziqhuba lo mkhuba wokukhetha.

Ukusebenza Okusimeme Kumabanga Amazinga Okushisa Aphakeme Kakhulu

Izinto zokusebenza zangaphandle kufanele zisebenze ngokwethembeka ngokusebenzisa izimo ezidlulele zesizini ezingaphazamisa noma zikhubaze ezinye izindlela zokupholisa umoya. Uma amazinga okushisa e-ambient edlula ama-degree Celsius angamashumi amathathu nanhlanu, amabhethri apholile emoyeni ashaja futhi akhiphe izinga lokushisa ukuze avimbele ukushisa ngokweqile, ehlisa umthamo otholakalayo ngokunembile lapho isidingo sokupholisa siphakama. Ngokuphambene, izimo ezingaphansi kweqhwa zinciphisa ukusabela kwe-electrochemical kanye nokulimala engozini uma ukushaja kwenzeka ngaphansi kwamazinga okushisa anconyiwe. Isistimu yethu yokugcina amandla okupholisa uketshezi igcina amazinga okushisa eseli ngaphakathi kwewindi elilungile kungakhathaliseki izimo zangaphandle, ijikeleza uketshezi lwe-dielectric ngamapuleti athinta iseli ngalinye. Lokhu kuphatha okushisayo okusebenzayo kugcina amandla agcwele angu-261kWh kulo lonke uhla lokusebenzisa amadigri angamashumi amathathu kuya kumashumi amahlanu nanhlanu. Ukuze kufakwe amapulazi elanga asogwadule, izindawo zokwakha ze-arctic, noma izindawo ezisogwini olushisayo, lokhu kuvumelana kuqinisekisa ukuthi izimpahla zokulondoloza ziletha ukusebenza okuthenjisiwe unyaka wonke. Isici esizenzakalelayo sokugcwalisa okupholisayo siphinde sinciphise ukuvakasha kokulungisa, sigcine uketshezi olupholile lwe-BESS lusebenza ezindaweni ezikude.

Ukukhulisa i-ROI Ngokusebenza Kahle Kakhulu kanye Nempilo Yomjikelezo

Imbuyiselo yezimali evela kumaphrojekthi wesitoreji incike kakhulu ekusebenzeni kahle kokuya nokubuya nempilo ende yebhethri. Iphesenti ngalinye lephoyinti lokulahlekelwa okusebenzayo phakathi nemijikelezo yokukhipha imali linciphisa ngokuqondile imali engenayo evela ku-arbitrage yamandla noma amasevisi egridi. Eyethu uhlelo lokugcina amandla okupholisa uketshezi ifinyelela ukusebenza kahle okungu-90% kokuya nokubuya ngokulawula okushisayo okunembayo okunciphisa ukumelana kwangaphakathi nemithwalo yezinambuzane. Amandla okuphendula asheshayo angu-125kW avumela ukubamba iqhaza ezimakethe zokulawula imvamisa ezidinga izinguquko ezisheshayo zokukhishwayo, okuthwebula imithombo yemali engenayo yenani eliphezulu. Ukwengeza, impilo yomjikelezo oyi-8,000-plus yamaseli ethu e-LFP, alondolozwe ngezimo ezikahle zokushisa, inweba ubude bephrojekthi ngaphambi kokuba kube nesidingo sokushintsha imali. Kubasebenzisi bezentengiselwano nabezimboni abahlola izindleko eziphelele zobunikazi, ukulungiselelwa kwe-BESS epholile okuwuketshezi kunikeza imbuyiselo ephakeme kakhulu uma kuqhathaniswa nezinye izindlela zokupholisa umoya ezehlisa isithunzi ngokushesha ngaphansi kwengcindezi yokushisa. I-Wenergy idizayina lawa masistimu ukuze kusetshenziswe ipulaki nokudlala okungadingi imisebenzi yomphakathi, isheshisa izikhathi zokukhokha ngezindleko ezincishisiwe zokufakwa.

Ukuhlanganiswa Kokuphepha Okubanzi Kwezindawo Zangaphandle

Ukufakwa kwangaphandle kuveza isitoreji samandla esimweni sezulu, izilwane zasendle, nezingozi zomzimba ezidinga izinyathelo zokuzivikela eziqinile. Isistimu yethu yokugcina amandla okupholisa uketshezi ihlanganisa ukwakheka kokuphepha kwezendlalelo eziningi ngaphakathi kwendawo ebiyelwe enesilinganiso se-IP55 imelana nothuli nokungena kwamanzi. Iluphu yokupholisa uketshezi ngokwayo ihlinzeka ngokuncishiswa kokushisa okushisayo ngokuqhubekayo ngokususa ukushisa kumaseli ngesikhathi sokusebenza okuvamile nokumunca amandla engeziwe phakathi nezimo zamaphutha. Amasistimu okucindezela i-aerosol azinikele asebenza kuleveli yemojuli lapho ethola amasiginesha angaphandle kwegesi, aqukethe izehlakalo ngaphambi kokusabalalisa. Izaziso zesikhathi sangempela ezivela Kuhlelo Lokuphathwa Kwebhethri zazisa opharetha ngezinkinga ezithuthukayo, ezivumela ukungenelela okukude noma ukuthunyelwa kwezisebenzi zesevisi. Ezikhungweni ezifana nezibhedlela, izikhungo zedatha, nengqalasizinda yomphakathi lapho ukunqamuka kuletha imiphumela enzima, lokhu kuvikela okuphelele kunikeza ithemba lokuthi ukufakwa kwe-BESS okupholile okuwuketshezi ngeke kwethule ubungozi obusha. Ibanga lamandla kagesi e-DC elibanzi lisuka ku-728 kuya ku-936 volts livumela ukucushwa kwe-Power Conversion System ehlukahlukene kuyilapho kugcinwa ukuhambisana kokuhlukaniswa.

Ukusabalalisa Okwenziwa Lula kanye Nokuthuthukisa Isikhala

Amaqembu ephrojekthi avame ukukhetha izingosi zokufaka zangaphandle ezisekelwe endaweni etholakalayo kunezimo zokusebenza ezifanele. Isistimu yethu yokugcina amandla okupholisa uketshezi ibhekana nalokhu ngokoqobo ngokusebenzisa izinyathelo ezihlangene kanye nezidingo ezincane zokulungiselela isayithi. Iluphu ehlanganisiwe yokupholisa uketshezi iqeda isidingo sokuvula amakhabethe ukuze kugeleze komoya, okuvumela ukupakishwa okuminyene komthamo ngaphakathi kwezindawo eziboshiwe. Idizayini ye-plug-and-play ayidingi izisekelo ezibambekayo noma ukuguqulwa kwesakhiwo, ukunciphisa izikhathi zesikhathi zokwakha kanye nezindleko. Ezinxanxatheleni zezitolo ezinezela isitoreji ezindaweni zokupaka ezikhona, noma amapaki ezimboni alungisa kabusha indawo phakathi kwezakhiwo, lokhu kwenziwa lula kubonakala kubalulekile. I-architecture ye-modular iphinde isekele ukunwetshwa kwamandla ngokusebenzisa amakhabethe engeziwe, ngoxhumo lokupholisa uketshezi olusezingeni elifanele kuwo wonke amayunithi. Njengoba amaphrojekthi engeziwe abona lezi zinzuzo zokusebenzisa, ukulungiselelwa kwe-BESS epholile okuwuketshezi kuya ngokuya kuba ukucaciswa okuzenzakalelayo kwezinhlelo zokusebenza zangaphandle zezohwebo nezimboni.

Ukushintshela ku-BESS yokupholisa uketshezi ekufakweni kwangaphandle kubonisa izinzuzo ezibambekayo ekusebenzeni okushisayo, izinzuzo zezomnotho, ukuhlanganiswa kokuphepha, kanye nobulula bokuthunyelwa. WenergyIsistimu yokugcina amandla okupholisa uketshezi engu-261kWh iletha lezi zinzuzo ngobunjiniyela obufakazelwe kanye nokuhlola okuqinile kuzo zonke izimo ezimbi kakhulu. Emaqenjini ephrojekthi ahlela ukuthunyelwa kwawo okulandelayo kwesitoreji sangaphandle, ubuchwepheshe obupholile obuwuketshezi bunikeza ukwethembeka okufunwa yizindawo zangaphandle.
