Njengochwepheshe omkhulu kuizixhumi ze-PV storage inverters, I-Amass ihlale yazi ngemakethe kanye nezidingo zamakhasimende, futhi ngokuqhubekayo iqinisa ucwaningo lomkhiqizo nokuthuthukiswa kanye nokuqanjwa kabusha kwezobuchwepheshe. Ukuthuthukisa ngokuqhubekayo izinga lenkonzo, ukuhlinzeka amakhasimende ngezixazululo ezisebenzayo, eziphephile, ezenziwe ngokwezifiso zokuxhuma ukusebenza kwe-lithium-ion, embonini Siye sanconywa embonini.
Umbhalo wakamuva we-heavyweight othi “Isaziso Ngokukhuthaza Amabhizinisi Aphehla Amandla Avuselelekayo Ukuze akhe noma Athenge Ikhono Eliphakeme Lokwenyusa Isikali Sokuhlanganiswa Kwegridi” sidinga ukwenyuka kwesikali sokuhlanganiswa kwegridi yokuphehla amandla avuselelekayo afakiwe.
Nakuba lingekho igama eliqondile lendawo yokugcina amandla, kodwa imakethe kade ibheka ukugcinwa kwamandla njengento evumayo ngokuqondile.
Ngenxa yezimo zemvelo eziguquguqukayo zokukhanya nomoya, okuholela emandleni okukhiphayo angazinzile, amandla e-photovoltaic namandla omoya awakwazi ukuhlangabezana nezidingo zamandla egridi njalo, okungukuthi, ukukhanya okulahliwe nomoya. Lokhu empeleni kuwukumosha. Uma la mandla amoshayo angagcinwa, izindleko zokukhiqiza amandla avuselelekayo zizoqhubeka nokwehla. Futhi lesi futhi isizathu esenza ukuqhuma kwenhloko-dolobha yokugcina amandla.
Ngemva kokucacisa isiqondiso esijwayelekile, kubaluleke kakhulu ukubheka ingxenye enamandla anamandla okuqhuma ayisisekelo.
Uma silandela lo mbandela, i-inverter iyisandla sokukhetha imbewu.
Isizathu salokhu akunzima ngempela ukusiqonda. Kuhlelo lwe-PV, i-inverter idlala umsebenzi obalulekile njengokuguqulwa kwe-AC/DC, ukulawula amandla, kanye nokushintshwa kwe-parallel/off-grid. Futhi ku-inverter, izingxenye zayo ezingaphansi kwe-inverter isixhumi ikhwalithi yokusebenza nayo idinga ukunaka.
Ngaphandle kosizo lwesistimu yokugcina amandla, ugesi okhiqizwa yi-PV uxhumeke ngokuqondile kugridi ngokusebenzisa inverter. Ngokugcinwa kwamandla, ugesi owenziwe yi-PV ugcinwa kuqala ohlelweni lokugcina nge-inverter, bese ugesi uxhunywe kugridi ngokusebenzisa inverter. Nakuba kukhona ukujika okukodwa, kodwa kuzokwazi ukusindisa ugesi olahlekile (ukukhanya okushiywe), ngaleyo ndlela kunwebe amahora okusetshenziswa kwe-PV.
Ukukhula kwesidingo sama-inverters akunakugwenywa. Ngokwesibikezelo socwaningo oluhlobene, i-inverter ye-PV yokugcina amandla yomhlaba wonke ehambelana namandla afakiwe afika ku-104GW ngo-2025, kuyilapho umthamo womhlaba wonke ofakiwe ngo-2020 wawungu-5.3GW kuphela. okungukuthi, izikhathi ezingama-20 eminyakeni emi-5, ngenani lokukhula elihlanganisiwe lonyaka elingaphezu kwama-80%.
Mhlawumbe abanye abantu bazothi, amandla amasha zonke izingxenye, isidingo sikhuphuka, ngakho-ke kuphi ukweqisa kwe-inverter?
Kalula nje, ama-inverters anomqondo osebenzisekayo. Isikhathi sokuphila sesitshalo esikhulu se-PV esibekwe phansi ngokuvamile siyiminyaka engama-20. I-inverter inqunyelwe izingxenye ze-elekthronikhi zangaphakathi (i-GBT, ama-capacitor, ama-inductors, njll.), impilo yesevisi ngokuvamile ayikho ngaphezu kweminyaka eyi-10. Ngamanye amazwi, i-PV power plant
Ngamanye amazwi, isitshalo se-PV sidinga okungenani ama-inverter angu-2 empilweni yaso. Lokhu kubangela ukuthi isidingo se-inverter singazuzi nje kuphela ku-PV ekhuphukayo, kodwa nakusitoko. Ukwenyuka kwesidingo esezansi nomfula ngokuvamile kuholela ekwenyukeni kwentengo yemikhiqizo ekhuphukayo. Kuphela, iphuzu elikhulu lesithakazelo embonini ye-inverter akukhona ukukhuphuka kwentengo, kodwa iphethini yemboni ohlangothini lokuhlinzeka. Isizathu sokuthi kungani ungadingi ukulangazelela ukukhuphuka kwamanani, ngoba ama-inverters anezithiyo zombili zobuchwepheshe, kodwa futhi nokupela izindleko eziphansi. Kuma-inverters e-photovoltaic, isibonelo, i-inverter engu-1 exhunywe ezingxenyeni eziyishumi nambili zamamojula we-photovoltaic, ama-inverters uma inkinga, lonke uhlelo luzokhubazeka. Ukugcizelelwa kokuphepha, ukwenza ama-inverters okuqala enziwa eJalimane. Kodwa-ke, ngokuphathelene nalo lonke uchungechunge lwemboni ye-PV, i-inverter ingumkhawulo ophansi kakhulu wokutshala izimali, ukusebenza kokukhanya kwempahla kwesixhumanisi, futhi lokhu kunikeza ukuqamekela okulandelayo okunezindleko eziphansi.
I-inverter exhunywe ezicucuni ezingaphezu kweshumi nambili zamamojula we-photovoltaic, lapho amatheminali e-photovoltaic inverter DC abaluleke kakhulu, ngesikhathi esifanayo nezingxenye ezibalulekile zokuxhuma, kanye nekhwalithi yezinkinga zayo, kodwa futhi kulula kakhulu ukuholela ekukhubazekeni lonke uhlelo lokugcina amandla!
Kamuva abakhiqizi basekhaya bangena efasiteleni lobuchwepheshe, futhi bakhipha umoya womsebenzi omkhulu, basakaza ngokushesha umthamo wokukhiqiza (ukusebenza kwempahla eningi embonini, ukukhuliswa kwamandla kuyashesha), ngekhwalithi enhle nemikhiqizo yamanani aphansi, ukuze bathathe isabelo semakethe embonini. ngesikhathi esifanayo, kodwa futhi i-inverter ohlelweni lwe-photovoltaic.Izindleko eziphelele zobunikazi zibe ngaphansi kuka-10%. Abakhiqizi basekhaya bathengise imikhiqizo yaphesheya kwezilwandle, iyunithi yentengo yeyunithi ye-inverter ephakathi nendawo engu-0.25 yuan / W kanye no-0.5 yuan / W, ephansi kakhulu kunamabhizinisi aphesheya kwezilwandle i-0.57 yuan / W kanye nenani lokudayisa elingu-0.78 yuan/W.
Ngaphezu kokukhuphuka kwentengo akuhambisani nephethini yemboni ngokwayo, kuzoba nobungozi bokuxabana namakhasimende. Kulezi zinsuku, into embi kakhulu ochungechungeni lwemboni ye-PV abakhiqizi beseli kanye namamojula angezansi. Phezulu komfula onesibindi sokukhuphula amanani, bazosebenzisana nesando abathi - intengo ikhuphuka kodwa iqondiswe ku-silicon, ingilazi ye-photovoltaic iyisibonelo. Njengengcweti ekongayoizixhumi zokugcina amandla, I-Amass yamukela indlela yokuthuthukiswa okuhlangene kwamaklayenti amaningi, okuqinisekisa ikhwalithi yemikhiqizo futhi yehlise izindleko ngesikhathi esifanayo, futhi igcine izindleko kumakhasimende amaningi. Isimo esihle kakhulu yisimo sokunqoba. Isimo sokuwina kuphela esingaqinisekisa intuthuko esimeme. Ngale ndlela, kubonakala sengathi iphethini elihle lemboni yi-hen ebeka amaqanda egolide ezandleni zemboni ye-inverter.
