Inkqubo yokugcina amandla ebhetri, eyaziwa ngokuba yi-BESS, isebenzisa iibhanki zeebhetri ezinokutshajwa kwakhona ukugcina umbane ogqithisileyo ukusuka kwigridi okanye kwimithombo ehlaziyiweyo ukuze isetyenziswe kamva.Njengoko amandla ahlaziyekayo kunye nobuchwepheshe begridi ehlakaniphile buhambela phambili, iinkqubo ze-BESS zidlala indima ebaluleke kakhulu ekuzinziseni ukunikezelwa kwamandla kunye nokwandisa ixabiso lamandla ohlaza.Zisebenza njani ke ezi nkqubo?
Inyathelo 1: Ibhanki yebhetri
Isiseko sayo nayiphi na i-BESS yindawo yokugcina amandla - iibhetri.Iimodyuli ezininzi zebhetri okanye "iiseli" zidityaniswe kunye ukwenza "ibhanki yebhetri" ebonelela ngomthamo ofunekayo wokugcina.Iiseli ezisetyenziswa ngokuqhelekileyo yi-lithium-ion ngenxa yoxinano lwamandla aphezulu, ubomi obude kunye nokukwazi ukutshaja ngokukhawuleza.Ezinye iikhemistri ezifana nelead-asidi kunye neebhetri zokuqukuqela nazo ziyasetyenziswa kwezinye iinkqubo.
Inyathelo 2: Inkqubo yokuguqula amandla
Ibhanki yebhetri iqhagamshela kwigridi yombane ngokusebenzisa inkqubo yokuguqula amandla okanye iPCS.I-PCS inezixhobo zamandla zombane ezifana ne-inverter, isiguquli, kunye nezihluzi ezivumela amandla ukuba ahambe kuwo omabini amacala phakathi kwebhetri kunye negridi.I-inverter iguqula i-current ngqo (DC) ukusuka kwibhetri ukuya kwi-alternating current (AC) esetyenziswa yigridi, kwaye umguquleli wenza umva ukuhlawula ibhetri.
Inyathelo 3: Inkqubo yokulawula ibhetri
Inkqubo yokulawula ibhetri, okanye iBMS, ibeka iliso kwaye ilawule ibhetri nganye ngaphakathi kwebhanki yebhetri.I-BMS ilungelelanisa iiseli, ilawula i-voltage kunye ne-current ngexesha lokutshaja kunye nokukhupha, kwaye ikhusela umonakalo ovela kwi-overcharging, i-overcurrents okanye i-deep discharge.Ibeka iliso kwiiparamitha eziphambili ezifana nombane, okwangoku kunye nobushushu ukwenza ngcono ukusebenza kwebhetri kunye nobomi.
Inyathelo lesi-4: Inkqubo yokupholisa
Inkqubo yokupholisa isusa ubushushu obugqithisileyo kwiibhetri ngexesha lokusebenza.Oku kubalulekile ukugcina iiseli ngaphakathi komgangatho wazo wobushushu kunye nokwandisa ubomi bomjikelo.Ezona ntlobo zixhaphakileyo zokupholisa ezisetyenziswayo kukupholisa ulwelo (ngokujikelezisa isisipholisi kwiipleyiti ezidibene neebhetri) kunye nokupholisa umoya (ukusebenzisa iifeni ukunyanzelisa umoya ngeentsimbi ezivalelekileyo).
Inyathelo lesi-5: Ukusebenza
Ngexesha leemfuno zombane eziphantsi okanye ukuveliswa kwamandla avuselelekayo, i-BESS ithatha amandla angaphezulu ngokusebenzisa inkqubo yokuguqula amandla kwaye iwagcine kwibhanki yebhetri.Xa imfuno iphezulu okanye i-renewables ingafumaneki, amandla agciniweyo akhutshwa abuyele kwigridi ngokusebenzisa i-inverter.Oku kuvumela i-BESS ukuba "itshintshe ixesha" amandla anokuphinda ahlaziyeke okwethutyana, izinzise amaza ombane wegridi kunye nombane, kunye nokubonelela ngamandla okugcina ngexesha lokucima.
Inkqubo yokulawula ibhetri ibeka iliso kwimeko yentlawulo yeseli nganye kwaye ilawula izinga lentlawulo kunye nokukhupha ukuthintela ukutshajiswa, ukufudumala kunye nokukhutshwa okunzulu kweebhetri - ukwandisa ubomi babo obusebenzisekayo.Kwaye inkqubo yokupholisa isebenza ukugcina ubushushu bebhetri ngokubanzi ngaphakathi koluhlu olukhuselekileyo lokusebenza.
Isishwankathelo, inkqubo yogcino lwamandla ebhetri isebenzisa iibhetri, izixhobo ze-elektroniki zamandla, ulawulo olukrelekrele kunye nolawulo lwe-thermal kunye ngendlela edityanisiweyo yokugcina umbane ogqithisileyo kunye nokukhupha amandla ngokufunwa.Oku kuvumela iteknoloji ye-BESS ukuba ikhulise ixabiso lemithombo yamandla avuselelekayo, yenza iigridi zamandla zisebenze ngakumbi kwaye zizinzileyo, kwaye zixhase utshintsho kwikamva lamandla ekhabhoni ephantsi.
Ngokunyuka kwemithombo yamandla ahlaziyekayo njengamandla elanga nawomoya, iinkqubo ezinkulu zokugcina amandla ebhetri (BESS) zidlala indima ebalulekileyo ekuzinziseni iigridi zamandla.Inkqubo yokugcina amandla ebhetri isebenzisa iibhetri ezinokutshajwa kwakhona ukugcina umbane ogqithileyo ukusuka kwigridi okanye kwizinto ezihlaziywayo kunye nokubuyisela loo mandla xa kuyimfuneko.Itekhnoloji ye-BESS inceda ukwandisa ukusetyenziswa kwamandla ahlaziyekayo ngamaxesha athile kunye nokuphucula ukuthembeka kwegridi ngokubanzi, ukusebenza kakuhle kunye nokuzinza.
I-BESS idla ngokuba namacandelo amaninzi:
I-1) Iibhanki zebhetri ezenziwe ngeemodyuli ezininzi zebhetri okanye iiseli ukunika amandla afunekayo okugcina amandla.Iibhetri zeLithium-ion zisetyenziswa kakhulu ngenxa yokuxinana kwamandla aphezulu, ubomi obude kunye nokutshaja okukhawulezileyo.Ezinye iikhemistri ezifana nelead-asidi kunye neebhetri zokuhamba nazo ziyasetyenziswa.
2) Inkqubo yokuguqula amandla (PCS) edibanisa ibhanki yebhetri kwigridi yombane.I-PCS iqulethe i-inverter, i-converter kunye nezinye izixhobo zokulawula ezivumela amandla ukuba ahambe kuzo zombini iindlela phakathi kwebhetri kunye negridi.
3) Inkqubo yolawulo lwebhetri (BMS) ebeka iliso kwaye ilawule imeko kunye nokusebenza kweeseli zebhetri nganye.I-BMS ilungelelanisa iiseli, ikhusela umonakalo ekutshajweni okanye ekukhutshweni okunzulu, kwaye ibeka iliso kwiiparamitha ezifana nombane, okwangoku kunye nobushushu.
4) Inkqubo yokupholisa esusa ubushushu obugqithisileyo kwiibhetri.Ulwelo okanye ukupholisa okusekwe emoyeni kusetyenziselwa ukugcina iibhetri ngaphakathi kowona mgangatho wobushushu osebenzayo kunye nokwandisa ubomi.
5) Indlu okanye isikhongozeli esikhusela kwaye sikhusele yonke inkqubo yebhetri.Iindawo ezivaliweyo zebhetri zangaphandle kufuneka zimelane nemozulu kwaye zikwazi ukumelana nobushushu obugqithisileyo.
Imisebenzi ephambili ye-BESS yile:
• Funxa umbane ogqithisileyo kwigridi ngexesha lemfuno ephantsi kwaye uwakhulule xa imfuno iphezulu.Oku kunceda ukuzinzisa umbane kunye nokuguquguquka kwamaza.
• Gcina umbane ohlaziyekayo kwimithombo efana ne-PV yelanga kunye neefama zomoya ezinemveliso eguquguqukayo kunye nexeshana, uze unikezele loo mandla agciniweyo xa ilanga lingakhanyisi okanye ungavuthi moya.Eli xesha-litshintsha amandla ahlaziyekayo ukuya kwixesha afuneka ngalo kakhulu.
• Ukubonelela ngombane ogciniweyo ngexesha leempazamo zegridi okanye ukucima ukugcina iziseko ezingundoqo zisebenza, nokuba kusesiqithini okanye kwimowudi yegridi.
• Ukuthatha inxaxheba kwiimpendulo zemfuno kunye neenkonzo ezincedisayo kwiinkqubo ngokunyusa okanye ukuhla amandla aphumayo xa efunwa, ngokubonelela ngolawulo lwamaza ombane kunye nezinye iinkonzo zegridi.
Ukuqukumbela, njengoko amandla ahlaziyekayo eqhubeka nokukhula njengepesenti yeegridi zamandla kwihlabathi liphela, iinkqubo ezinkulu zokugcina amandla ebhetri ziya kudlala indima ebaluleke kakhulu ekwenzeni loo mandla acocekileyo athembeke kwaye afumaneke ubusuku nemini.I-teknoloji ye-BESS iya kunceda ukwandisa ixabiso lokuhlaziywa kwakhona, ukuzinzisa iigridi zamandla kunye nokuxhasa ukutshintshela kwikamva elizinzileyo, eliphantsi kwekhabhoni yamandla.
