Nakuba abantu abaningi emhlabeni wonke bekhuthazwa ukuba bafake amasistimu kagesi welanga ophahleni lwendlu noma kwenye indawo endaweni yabo, akunjaloizinhlelo zebhethri zelanga zasekhayaokokugcina. Kodwa-ke, indima yabo esakhiweni sanoma yikuphi ukufakwa ibalulekile, ikakhulukazi ngoba banalezi zindlela ezi-4 ezivelele zokusebenza: Ukunyuka kwe-PV Self-consumption / Peaking Okubalulekile kokuphakelayo Amandla Okusekela Ngokulondoloza Amasistimu angaphandle kwegridi Ukwandisa i-PV Self-consumption / Peak Regulation Sonke siyazi ukuthi amasistimu kagesi welanga awakwazi ukuhlangabezana nesidingo sikagesi ebusuku, lapho ugesi wethu usetshenziswa ebusuku, ngakho-ke enye yezinjongo zokufaka isistimu yebhethri yelanga kusistimu yakho ye-PV ukukhulisa ukusebenzisa kwakho i-PV. isilinganiso. Uma isebenza kule modi, i-inverter izogcina amandla amaningi e-PV akhiqizwe ngangokunokwenzeka. Lokhu kusho ukuthi wonke ugesi ongasetshenzisiwe (ofunwa) yindlu phakathi nosuku uzogcinwa ebhange lebhethri le-lithium. Uma ungenayo ibhange lebhethri le-lithium elifakiwe, amandla asele azothunyelwa kuhlelo lokusebenza kule modi. Le modi ilungele abantu abafuna ukusebenzisa amandla abo e-PV ebusuku lapho amandla egridi ebiza kakhulu. Lo mqondo siwubiza ngokuthi “i-arbitrage yamandla” noma “ukuphakama”, futhi njengoba amanani entengo enyuka namuhla, sikholelwa ukuthi abantu abaningi bangancamela ukusebenzisa le modi kunezinye izindlela. Okubalulekile kokuphakelayo Uma le modi yenziwe yasebenza, isistimu izobeka phambili ukunikeza amandla kugridi. Lokhu kusho ukuthi ibhethri ngeke Lishajwe noma likhululwe ngaphandle uma kuvuliwe Isikhathi sokushaja futhi silungiswa kahle. Imodi yokukhathazeka ngokuphakelayo ingcono kakhulu kubantu abanamasistimu amakhulu e-PV ahlobene nokusetshenziswa kwamandla kanye nobukhulu bebhethri. Isici salokhu kulungiselelwa ukuthengisa amandla amaningi ngangokunokwenzeka kugridi futhi sisebenzise ibhethri kuphela kumawindi amancane esikhathi noma lapho amandla egridi elahlekile. Amandla Okusekela Ngokulondoloza Ezindaweni ezivame ukushaywa yizinhlekelele zemvelo, amagridi abo kagesi ngokuvamile alahlekelwa amandla ngenxa yezinhlekelele zemvelo, ngakho-ke kubaluleke kakhulu ukugcina ikhaya lakho Ezindaweni ezivame ukushaywa yizinhlekelele zemvelo, amagridi abo kagesi ngokuvamile alahlekelwa amandla ngenxa yezinhlekelele zemvelo. , ngakho-ke kubaluleke kakhulu ukugcina izinto zakho zikagesi zasendlini zisebenza ngesikhathi sokuphela kukagesi, ngakho-ke amasistimu ebhethri elanga lasekhaya angaba usizo kakhulu ezimweni ezinjalo. Uma isebenza kumodi yamandla eyisipele, isistimu izophuma kuphela kusistimu yebhethri yelanga lasekhaya uma kwenzeka ukuphela kwamandla. Isibonelo, uma i-SOC eyisipele ingu-80%, ibhange lebhethri le-lithium akufanele lidlule u-80%. Ngisho nasekusetshenzisweni kwangasese embonini, amabhizinisi nasemakhaya, amakhono weIbhethri ye-ESSnikeza izinzuzo ezinkulu kunokunikeza nje amandla uma kwenzeka iphutha lenethiwekhi. Ngisho nasekusetshenzisweni kwangasese embonini, amabhizinisi nasemakhaya, amandla ebhethri ye-ESS anikeza izinzuzo ezinkulu kunokuhlinzeka nje ngamandla uma kwenzeka inethiwekhi ihluleka. Omunye umehluko ogqama kakhulu lapha ukuthi, uma kuqhathaniswa nezitshalo zamandla ezimo eziphuthumayo ezinamandla kadizili, i-solar battery bank lithium powered energy storage Omunye umehluko ogqama kakhulu lapha ukuthi, uma kuqhathaniswa nezitshalo zamandla ezimo eziphuthumayo ezisebenza ngodizili, i-solar battery bank lithium powered energy storage. amasistimu anamandla okusabela ngokushesha ukuze agweme ukunqamuka kukagesi okuncane, okungadala ukucisha kukagesi:
- Ukwehluleka emishinini yezinkampani
- Ukuma kwemigqa yokukhiqiza, okuholela ekulahlekeni komkhiqizo.
- Ukulahlekelwa kwezomnotho
Amasistimu angaphandle kwegridi Kukhona amazwe nezifunda ezingawujabuleli ugesi ovela kugridi ngenxa yendawo ekude, nakuba zingafaka ama-solar panel ukuze zikhiqize amandla, kodwa lokhu kuyisikhashana kakhulu, lapho kungekho mandla elanga, kusadingeka bahlale kuwo. ubumnyama, ngakho-ke ukusetshenziswa kwebhethri yelanga yasendlini kungenza izinga labo lokusebenzisa amandla elanga libe ngu-80% noma ngaphezulu, ngejeneretha noma ezinye izinto zokuphehla amandla, lesi sibalo singafinyelela ku-100%. Uma usebenza kule modi, i-inverter izonikeza amandla kumthwalo oyisipele asuka ebhange lebhethri le-PV ne-lithium, kuye ngomthombo wamandla otholakalayo. Isebenza Kanjani Isistimu Yebhethri Yelanga Lasekhaya? Amasistimu ebhethri elanga lasekhaya, okuhlanganisa amamojula elanga, izilawuli, ama-inverters, amabhange ebhethri ye-lithium, imithwalo, nezinye izinto zokusebenza, zinemizila eminingi yobuchwepheshe. Ngokwendlela amandla ahlanganiswe ngayo, okwamanje kunezihloko ezimbili eziyinhloko: "DC Coupling" kanye "AC Coupling". Ngokuyisisekelo, amaphaneli elanga athatha amandla avela elangeni futhi la mandla ashajwa ku-aikhaya lithium ibhethri(okungaphinda kugcine amandla asuka kugridi). I-inverter ibe yingxenye eguqula amandla athunjiwe abe amandla amanje afanele ukusetshenziswa. Ukusuka lapho, ugesi ulethwa kuphaneli kagesi yasekhaya. Ukuhlanganiswa kwe-DC:Ugesi we-DC ovela kumojula ye-PV ugcinwa kumaphakethe ebhethri lelanga lasekhaya ngesilawuli, futhi igridi ingaphinda ishaje amaphakethe ebhethri lelanga lasekhaya ngesiguquli se-DC-AC esinezinhlangothi ezimbili. Iphuzu lokuhlangana kwamandla lisekupheleni kwebhethri lelanga le-DC. Ukuhlanganiswa kwe-AC:Amandla e-DC asuka kumojula ye-PV ashintshwa abe amandla e-AC ngesiguquli futhi aphakelwe ngokuqondile emthwalweni noma kugridi, futhi igridi ingaphinda ishaje amaphakethe ebhethri lelanga lasekhaya ngesiguquli se-DC-AC esikabili. Iphuzu lokuhlangana kwamandla lisekupheleni kwe-AC. I-DC coupling kanye ne-AC coupling kokubili kuyizixazululo ezivuthiwe, ngayinye inezinzuzo zayo kanye nokubi, kuye ngokuthi isicelo, khetha isisombululo esifanele kakhulu. Mayelana nezindleko, uhlelo lokuhlanganisa lwe-DC lubiza kancane kunohlelo lokuhlanganisa lwe-AC. Uma udinga ukwengeza isistimu yebhethri yelanga lasekhaya ohlelweni lwe-PV oluvele lufakiwe, kungcono ukusebenzisa i-AC coupling, inqobo nje uma ibhange lebhethri ye-lithium kanye ne-bi-directional converter yengezwe, ngaphandle kokuthinta uhlelo lokuqala lwe-PV. Uma kuwuhlelo olusanda kufakwa nolungekho kugridi, i-PV, ibhange lebhethri ye-lithium, kanye ne-inverter kufanele yakhelwe ngokuya ngamandla omthwalo womsebenzisi nokusetshenziswa kwamandla, futhi ifaneleka kakhulu ukusebenzisa isistimu yokuhlanganisa ye-DC. Uma umsebenzisi enomthwalo omningi emini nangaphansi ebusuku, kungcono ukusebenzisa i-AC coupling, imojula ye-PV inganikeza amandla kumthwalo ngokuqondile nge-inverter exhunywe kugridi, futhi ukusebenza kahle kungafinyelela ngaphezu kwe-96%. Uma umsebenzisi enomthwalo omncane emini nangaphezulu ebusuku, futhi amandla e-PV adinga ukugcinwa emini futhi asetshenziswe ebusuku, i-DC coupling ingcono, futhi i-PV module igcina amandla ebhange lebhethri le-lithium ngokusebenzisa isilawuli. , futhi ukusebenza kahle kungafinyelela ngaphezu kwama-95%. Manje njengoba usuzazi izinzuzo zezinhlelo zebhethri yelanga lasekhaya kuwe, ungaphetha ngokuthi isixazululo asivumeli nje kuphela ukuguqulwa kwamandla ku-100% wamandla avuselelekayo kodwa futhi silondoloza imali kuzikweletu zikagesi zokusetshenziswa ekhaya, ezentengiselwano noma zezimboni. Amasistimu ebhethri elanga lasekhaya ayisixazululo sale nkinga. Sondela ku-BSLBATT, umkhiqizi ohamba phambili wei-lithium-ion battery energy storage systemseChina.
