Noocyada beddelka tamarta kaydinta tamarta
Jidka farsamada: Waxaa jira laba waddo oo waaweyn: isku xirka DC iyo isku xirka AC
Nidaamka kaydinta sawir-qaadista waxaa ka mid ah baalal qoraxda, kontaroolayaasha,rogayaasha qoraxda, baytariyada kaydinta tamarta, rar iyo qalab kale. Waxaa jira laba dariiqo farsamo oo waaweyn: isku xirka DC iyo isku xirka AC. Isku xirka AC ama DC waxaa loola jeedaa habka looxa qoraxda la isugu xiro ama loogu xiro kaydinta tamarta ama nidaamka batteriga. Nooca isku xirka u dhexeeya muraayadda qorraxda iyo baytarigu wuxuu noqon karaa AC ama DC. Inta badan wareegyada elektiroonigga ah waxay isticmaalaan DC, baararka cadceedda waxay dhaliyaan DC, baytariyaduna waxay kaydiyaan DC, laakiin inta badan qalabka korontada ayaa ku shaqeeya AC.
Hybrid photovoltaic + nidaamka kaydinta tamarta, taas oo ah, hadda tooska ah ee ay dhaliso moduleka sawir-qaadista waxaa lagu kaydiyaa batteriga iyada oo loo marayo kontaroolaha, iyo shabaqyada sidoo kale waxay ku dallaci kartaa batteriga iyada oo loo marayo beddelaha labada dhinac ee DC-AC. Meesha tamarta lagu ururiyo waxay ku taal dhamaadka baytariyada DC. Inta lagu jiro maalinta, koronto-soo-saarka sawir-qaadista ayaa marka hore keena culeyska, ka dibna ku dallaca batteriga iyada oo loo marayo kontaroolaha MPPT. Nidaamka kaydinta tamarta wuxuu ku xiran yahay shabagga, iyo awoodda xad-dhaafka ah waxaa lagu xiri karaa shabakada; habeenkii, batterigu wuu soo daayaa si uu u keeno culeyska, iyo qaybta aan ku filneyn waxaa lagu kabi karaa shabagga; Marka shabaggu uu korontadu ka baxo, koronto-dhaliyaha sawir-qaadista iyo baytariyada lithium-ka ayaa bixiya korontada culeyska ka baxsan, iyo culeyska ku xiran shabakadda lama isticmaali karo. Marka awoodda culeysku ka weyn tahay koronto-dhaliyaha sawir-qaadista, shabaqyada iyo sawir-qaadista waxay awood u siin karaan culeyska isla mar ahaantaana. Sababtoo ah koronto-soo-saarka sawir-qaadista iyo isticmaalka awoodda culeysku maaha mid deggan, waxay ku tiirsan yihiin baytariyada si ay u dheelitiraan tamarta nidaamka. Intaa waxaa dheer, nidaamku wuxuu sidoo kale taageerayaa isticmaalayaasha si ay u dejiyaan ku dallacaadda iyo wakhtiga shubista si ay u daboolaan baahida awoodda isticmaalaha.

Inverter-ka isku-dhafka ah wuxuu isku daraa shaqeynta ka-baxsan si loo horumariyo waxtarka dallacaadda. Rog-rogayaasha grid-ku-xidhan waxay si toos ah u damiyaan korantada nidaamka kaaga cadceedda inta ay korontadu go'an tahay sababo ammaan dartood. Isku-bedelayaasha isku-dhafka ah, dhanka kale, waxay u oggolaanayaan isticmaaleyaasha inay lahaadaan awood kabaxsan iyo koronto isku mar, markaa korontadu waa la isticmaali karaa xitaa marka korontadu go'do. Rogayaasha isku-dhafka ah waxay fududeeyaan la socodka tamarta, u oggolaanaya xogta muhiimka ah sida waxqabadka iyo wax soo saarka tamarta in lagu hubiyo iyada oo loo marayo guddiga beddelka ama aaladaha smart ee ku xiran. Haddii nidaamku leeyahay laba rogaal-celin, waa in si gaar ah loola socdo. Isku xirka DC wuxuu yareeyaa khasaaraha beddelka AC-DC. Waxtarka ku dallaca batteriga waa qiyaastii 95-99%, halka isku xirka AC uu yahay 90%.
Rogayaasha isku-dhafan waa kuwo dhaqaale, cufan, oo sahlan in la rakibo. Ku rakibida beddelaha cusub ee isku-dhafan ee leh baytari DC-ku-xidhan ayaa laga yaabaa inay ka jaban tahay dib-u-habaynta baytari AC-ku-xidhan yahay ee nidaamka jira sababtoo ah kontarooluhu wuu ka jaban yahay beddelka-xirfad-xidhka, beddelku wuu ka jaban yahay golaha qaybinta, iyo DC- Xalka la isku daray ayaa sidoo kale laga dhigi karaa kontaroole-inverter all-in-one, labadaba qalabka iyo kharashka rakibidda. Gaar ahaan nidaamyada tamarta yar iyo kuwa dhexdhexaadka ah ee ka baxsan-grid-ka, nidaamyada DC-ku-xidhan ayaa ah kuwo aad qaali u ah. Rogayaasha isku-dhafka ah ayaa ah kuwo aad u habaysan, wayna fududahay in lagu daro qaybo cusub iyo kontaroolayaal. Qaybaha dheeriga ah ayaa si fudud loogu dari karaa iyadoo la isticmaalayo kontaroolayaasha cadceedda ee DC oo qiimo jaban. Qalab beddelayaasha isku-dhafka ah waxaa loogu talagalay inay isku daraan kaydinta wakhti kasta, taas oo sahlaysa in lagu daro batteriga. Nidaamyada rogayaasha isku-dhafka ah waa kuwo is haysta, adeegsada baytariyada korantada sare leh, waxayna leeyihiin cabbirro fiilo yar iyo khasaare hoose.

Si kastaba ha ahaatee, rogrogayaasha isku-dhafka ah kuma habboona cusboonaysiinta nidaamyada qorraxda ee jira, iyo nidaamyada waaweyn ayaa aad u adag oo qaali ah in la rakibo. Haddii adeegsaduhu rabo inuu cusboonaysiiyo nidaamka qorraxda ee jira si uu ugu daro kaydinta batteriga, doorashada beddelka isku-dhafan ayaa laga yaabaa inay xaaladda sii murjiso, beddelaha batariguna wuxuu noqon karaa mid kharash badan leh sababtoo ah xulashada rakibidda qalab beddele isku-dhafan waxay u baahan tahay dib-u-shaqayn dhammaystiran oo qaali ah oo dhan. nidaamka qoraxda. Nidaamyada waaweyni waa kuwo aad u adag in la rakibo oo aad qaali u ah sababtoo ah baahida loo qabo kontaroolayaasha tamarta sare leh. Haddii koronto la isticmaalo in ka badan inta lagu jiro maalinta, waxaa jiri doona hoos u dhac yar oo waxtarka ah sababtoo ah DC (PV) ilaa DC (batt) ilaa AC.
Nidaamka kaydinta tamarta ee isku xidhan ee sawirkavoltaic + tamarta, oo sidoo kale loo yaqaan AC transformation photovoltaic + nidaamka kaydinta tamarta, waxay ogaan kartaa in awooda DC ee ay soo saartay moduleka sawir-qaadista loo beddelo awooda AC iyada oo loo marayo rookaha-kuxiran ee koronto, ka dibna awooda xad dhaafka ah ayaa loo beddelaa galay koronta DC oo lagu kaydiyaa batteriga iyada oo loo marayo beddelka tamarta kaydinta AC. Meesha tamarta ururintu waa dhamaadka AC. Waxaa ka mid ah nidaamka korantada ee sawir-qaadka iyo nidaamka korontada ee baytariga. Nidaamka sawir-qaadista wuxuu ka kooban yahay sawir-qaade sawir-qaade ah iyo koronto-rogayaal-ku-xiran, iyo nidaamka batterigu wuxuu ka kooban yahay baakad batari iyo rogaal-celin laba jiho ah. Labada nidaam waxay u shaqayn karaan si madax-banaan iyaga oo aan faragelin midba midka kale, ama waxaa laga saari karaa korantada weyn si ay u sameeyaan nidaamka microgrid.

Nidaamka isku xirka AC waa 100% la jaan qaadaya korantada, fududahay in la rakibo oo si sahlan loo ballaariyo. Qaybaha rakibaadda caadiga ah ee qoyska ayaa la heli karaa, iyo xitaa nidaamyada waaweyn (2KW ilaa heerka MW) si fudud ayaa loo ballaarin karaa waxaana lagu dari karaa koronto-dhaliyaha-ku-xiran iyo kuwa gooni-gooni ah (cutubyada naaftada, marawaxadaha dabaysha, iwm.). Inta badan xadhkaha cadceedda rogayaasha ee ka sarreeya 3kW waxay leeyihiin laba qaybood oo MPPT ah, sidaas darteed xadhkaha dhaadheer ee baalasha ayaa lagu rakibi karaa jihooyin kala duwan iyo xaglo leexin. Xadhkaha sare ee DC, isku xidhka AC waa sahlan tahay, ka adag sidaas darteedna waa ka kharash yar tahay in lagu rakibo habab waaweyn marka loo eego nidaamyada isku xidhan ee DC ee u baahan kontaroolayaal badan oo MPPT ah.
Isku-xidhka AC wuxuu ku habboon yahay isbeddelka nidaamka, waxayna aad u fiican tahay isticmaalka culeyska AC inta lagu jiro maalinta. Nidaamyada PV-ga ku xiran ee hadda jira ayaa loo bedeli karaa habab kaydinta tamarta oo leh kharashyo maalgashi oo hooseeya. Waxay siin kartaa isticmaalayaasha ilaalinta korantada badbaadsan marka shabaggu uu ka baxo korontadu. Waxay ku habboon tahay nidaamyada PV-ga ku xiran ee ka yimid soosaarayaal kala duwan. Nidaamyada isku xirka AC horumarsan ayaa inta badan loo adeegsadaa nidaamyada waaweyn ee ka-baxsan waxayna adeegsadaan xargaha rogayaasha qoraxda oo ay la socdaan beddelayaasha habab badan oo horumarsan ama inverter/chargers si loo maareeyo baytariyada iyo koronto-dhaliyeyaasha. In kasta oo ay fududdahay in la dejiyo oo xoog badan, haddana wax yar ayay ka tayo yar yihiin (90-94%) marka baytari ku dallacaan marka la barbardhigo nidaamyada isku xirka DC (98%). Si kastaba ha ahaatee, nidaamyadani waa kuwo aad waxtar u leh marka ay xoojiyaan culeysyada AC ee sarreeya inta lagu jiro maalinta, oo gaaraya in ka badan 97%, iyo nidaamyada qaar ayaa lagu ballaarin karaa qalabyo badan oo qorraxda si ay u sameeyaan microgrids.
Isku xirka AC waa mid aan waxtar lahayn oo aad ugu qaalisan nidaamyada yaryar. Tamarta gelaysa baytariga ku jira isku xidhka AC waa in laba jeer la beddelaa, marka isticmaaluhu bilaabo isticmaalka tamartaas, waa in mar kale la beddelaa, oo ku kordhisa khasaare badan nidaamka. Sidaa darteed, marka la isticmaalayo nidaamka batteriga, waxtarka isku xirka AC wuxuu hoos ugu dhacayaa 85-90%. Qalab rogayaasha AC ee isku xiran ayaa aad ugu qaalisan nidaamyada yaryar.
Nidaamka kaydinta tamarta ee guriga ka baxsan ayaa guud ahaan ka kooban qaybo sawir-voltaic ah, baytariyada lithium-ka, rogayaasha kaydinta tamarta ka baxsan, xamuulka iyo dhaliyaasha naaftada. Nidaamku wuxuu xaqiijin karaa ku dallacaadda tooska ah ee baytariyada iyadoo loo marayo sawir-qaadista iyadoo loo marayo beddelka DC-DC, wuxuuna sidoo kale xaqiijin karaa beddelka laba jiho ee DC-AC ee ku dallacaadda iyo soo daynta batteriga. Inta lagu jiro maalinta, koronto-soo-saarka sawir-qaadista ayaa marka hore keena culeyska, ka dibna dallaca batteriga; habeenkii, batterigu wuu soo daayaa si uu u keeno rarka, marka batterigu ku filnaado, culeyska waxaa keenaya koronto-dhaliyeyaasha naaftada. Waxay dabooli kartaa baahida koronto ee maalinlaha ah ee meelaha aan lahayn xadhkaha korontada. Waxa lagu dari karaa matoorayaasha naaftada si ay awood ugu siiso matoorada naaftada in ay ku shubaan rar ama ku dallacaan baytariyada. Inta badan rogayaasha kaydinta tamarta ka baxsan ma laha shahaado isku xirka shabagga, iyo xitaa haddii nidaamku leeyahay shabag, laguma xidhi karo shabagga.

Xaaladaha lagu dabaqi karo beddelayaasha kaydinta tamarta
Rogayaasha kaydinta tamarta ayaa leh saddex hawlood oo waaweyn, oo ay ku jiraan xiirashada ugu sarreysa, korantada kaydinta iyo sahay koronto oo madaxbannaan. Marka laga eego dhinaca gobolka, xiirashada ugu sarreysa waa baahida Yurub. Tusaale ahaan Jarmalka, qiimaha korontada ee Jarmalku waxa uu gaadhay 2.3 yuan/kWh sanadka 2019, isaga oo kaalinta kowaad kaga jira aduunka. Sanadihii la soo dhaafay, qiimaha korontada Jarmalka ayaa sii waday inuu kordho. Sannadka 2021, qiimaha korantada guryaha Jarmalku waxa uu gaadhay 34 senti yuuro/kWh, halka qaybinta iyo kaydinta sawirka voltaic/photovoltaic ay tahay kaliya 9.3/14.1 euro cents/kWh, taas oo 73%/59% ka hoosaysa qiimaha korontada guriga. Qiimaha korontada ee la deggan yahay waa la mid ah farqiga u dhexeeya qaybinta sawir-qaadista iyo kharashka kaydinta korantada ayaa sii wadi doonta ballaarinta. Nidaamyada kaydinta iyo qaybinta sawir-qaadista ee guriga ayaa yarayn kara kharashka korontada, sidaa darteed isticmaalayaasha meelaha qiimaha korontadu sarreeyo waxay leeyihiin dhiirigelin xooggan oo lagu rakibo kaydinta qoyska.

Suuqa culeyska ugu sarreeya, isticmaalayaashu waxay doortaan beddelayaasha isku-dhafan iyo nidaamyada baytariyada AC-ku-xidhan, kuwaas oo ka qiimo badan oo sahlan in la soo saaro. Dabeyeyaasha baytariga ka baxsan ee leh transformers culus ayaa aad qaali u ah, rogayaasha isku-dhafan iyo nidaamyada baytariyada AC-ku-xidhan ayaa adeegsada beddelaadaha aan beddelka lahayn ee leh beddelaadaha beddelka. Rogayaashan cufan iyo kuwa fudfudud waxay leeyihiin qiimayn hoose oo soo saarid koronto ah, laakiin waa kuwo kharash-ool ah, ka raqiisan oo sahlan in la soo saaro.
Korontada kaydinta waxaa u baahan Maraykanka iyo Japan, iyo sahay koronto oo madax banaan ayaa loo baahan yahay suuqa degdega ah, oo ay ku jiraan Koonfur Afrika iyo gobollada kale. Marka loo eego EIA, celceliska muddada korontadu ka go'day Mareykanka sanadka 2020 ayaa dhaaftay 8 saacadood, taasoo inta badan ay saameysay deggenaanshaha baahsan ee deganeyaasha Mareykanka, gabowga qaar ka mid ah xadhkaha korontada, iyo masiibooyinka dabiiciga ah. Codsiga nidaamka qaybinta iyo kaydinta sawir-qaadista qoyska ayaa yarayn kara ku-tiirsanaanta korantada waxayna kordhin kartaa isku halaynta korontadu dhinaca adeegsadaha. Nidaamka kaydinta tamarta sawir-qaadista ee Maraykanka ayaa ka weyn oo ku qalabaysan baytariyo badan sababtoo ah waxay u baahan tahay inay kaydiso koronto si ay ula tacaasho masiibooyinka dabiiciga ah. Korontada madax-banaani waa baahi suuqa oo degdeg ah. Wadamada sida Koonfur Afrika, Pakistan, Lubnaan, Filibiin, iyo Vietnam, halkaas oo silsiladda sahayda caalamiga ah ay adag tahay, kaabayaasha qaranku kuma filna inay taageeraan isticmaalka korontada ee dadka, markaa isticmaalayaashu waa in lagu qalabeeyaa nidaamyada kaydinta tamarta tamarta ee guriga.

Rogayaasha isku-dhafka ah waxay leeyihiin xoogaa xaddidaad ah sida awoodda kaydinta. Marka la barbar dhigo beddelayaasha baytariyada bannaanka ka baxsan, rogayaasha isku-dhafan waxay leeyihiin xaddidaadyo, badiyaa kor u kac xaddidan ama soo saarista koronta ugu sarreysa inta lagu jiro korontadu. Intaa waxaa dheer, qaar ka mid ah beddelayaasha isku-dhafka ah ma laha awood awood celin ah ama awood xaddidan oo xaddidan, sidaas darteed kaliya culeysyada yaryar ama lagama maarmaanka ah sida nalalka iyo wareegyada tamarta aasaasiga ah ayaa lagu taageeri karaa inta lagu jiro korontadu, iyo nidaamyo badan ayaa yeelan doona dib u dhac 3-5 ilbiriqsi inta lagu jiro awoodda. maqnaansho. Rogayaasha ka-baxsan waxay bixiyaan koronto aad u sareysa iyo soo saarid koronto oo ugu sarreysa waxayna xamili karaan culeysyo firfircoon oo sarreeya. Haddii isticmaalayaashu ay qorsheeyaan inay ku xoojiyaan qalabka sare-u-qaadista sida bambooyin, kombaresarada, mishiinnada dharka lagu dhaqo, iyo qalabka korontada, gaddoonku waa inuu awoodaa inuu xamili karo culeysyada qalliinka sareeyo.

Marka lagu daro nidaam cusub, isticmaalka sawir-qaadaha iyo kaydinta tamarta isku-dhafka ah waxay yareyn kartaa kharashka qalabka iyo kharashka rakibidda, sababtoo ah hal qalab ayaa gaari kara xakamaynta isku-dhafka ah iyo leexiyaha. Xakamaynta iyo beddelka beddelka ee nidaamka isku-xidhka DC-ga ayaa ka raqiisan is-beddelka ku-xiran ee ku-xiran iyo golaha qaybinta ee nidaamka isku-xidhka AC, markaa xalka isku-xidhka DC wuxuu ka jaban yahay xalka isku-xidhka AC. Nidaamka isku xirka DC, kantaroolaha, baytariga iyo inverter-ku waa taxane, xiriirku aad buu u adag yahay, dabacsanaantuna waa liidataa. Nidaamyada cusub ee la rakibay, sawir-qaadaha, baytariyada, iyo rogayaasha waxaa loo qaabeeyey iyadoo loo eegayo awoodda rarka isticmaalaha iyo isticmaalka korontada, si ay ugu habboon yihiin beddelayaasha isku-dhafan ee DC-ku xiran.
Alaabooyinka roga-rogayaasha isku-dhafan ee DC-ku-xidhan ayaa ah isbeddelka guud, iyo wax-soo-saareyaasha gudaha ayaa geeyey.

Kala beddelka batteriga nooca kala qaybsan ayaa aad caan uga ah rakibayaasha, laakiin beddelka batteriga oo dhan-ku-jira waa isbeddelka horumarka mustaqbalka. Qalab rogayaasha isku-dhafan ee kaydka qoraxda waxa loo qaybiyaa beddelayaal isku-dhafan oo si gaar ah loo iibiyo iyo nidaamyada kaydinta tamarta baytari (BESS) kuwaas oo wada iibiya rogayaasha iyo baytariyada. Waqtigan xaadirka ah, iyada oo ganacsatadu ay xakameynayaan kanaalada, macaamiisha tooska ah ayaa xoogaa xoog leh, iyo alaabooyinka leh baytariyada kala duwan iyo kuwa rogaal-celinta ayaa aad caan u ah, gaar ahaan meel ka baxsan Jarmalka, sababtoo ah way fududahay in la rakibo oo la ballaariyo, waxayna yareyn karaan kharashka wax iibsiga. Haddii mid ka mid ah alaab-qeybiyuhu aanu keeni karin baytariyada ama beddelayaasha, waxaad heli kartaa alaab-qeybiye labaad, keenistana waxay noqon doontaa dammaanad dheeraad ah. Isbeddelka ka jira Jarmalka, Mareykanka, iyo Japan waa mashiinno-hal-hal ah. Mashiinka-isku-dhafka ah wuxuu badbaadin karaa wax badan oo ka mid ah dhibaatooyinka iibka ka dib, waxaana jira arrimo shahaado. Tusaale ahaan, shahaadada nidaamka dab-demiska ee Maraykanka waxay u baahan tahay in lagu xidho rogaha. Isbeddelka tignoolajiyada ee hadda jira wuxuu ku wajahan yahay mashiinnada oo dhan, laakiin marka la eego iibka suuqa, nooca kala qaybsanaanta ayaa aad u aqbalaya rakibayaasha.
Inta badan soosaarayaasha gudaha waxay bilaabeen inay geeyaan mashiinada isku dhafan ee baytari-rogadka. Warshadaha sidaShohang Xinneng, Growatt, iyo KehuaDhammaantood doorteen qaabkan. Shougang Xinneng batteriga kaydka tamarta ee iibka 2021 wuxuu gaadhay 35,100 pcs, korodhka 25 jeer marka la barbar dhigo 20 sano; Kaydinta tamarta Growatt ee 2021 iibka baytarigu waxa uu ahaa 53,000 oo qaybood, shan-laab ayaa kordhay 20 sano ka hor. Tayada aadka u fiican ee rogayaasha kaydinta tamarta Airo ayaa horseeday koritaanka joogtada ah ee iibinta baytariga.

Nidaamyada isku-xidhka ah ee DC, nidaamka baytariyada danabkoodu sarreeyo ayaa aad waxtar u leh, laakiin waa ka qaalisan yihiin haddii ay dhacdo yaraanta batteriga tamarta sare. Marka la barbardhigo hababka baytariyada 48V, baytariyada danabka sare waxay leeyihiin kala duwanaansho korantada shaqaynaysa oo ah 200-500V DC, khasaaraha fiilooyinka hooseeyo iyo waxtarka sare, sababtoo ah muraayadaha qoraxda waxay inta badan ku shaqeeyaan 300-600V, oo la mid ah tamarta batteriga, iyo khasaaro aad u hooseeya iyo waxtarka sare. beddelayaasha DC-DC waa la isticmaali karaa. Nidaamyada baytariga korantada sarreeya waxay leeyihiin qiimaha batariyada oo sarreeya waxayna ka hooseeyaan qiimaha beddelka marka loo eego nidaamyada tamarta hooseeya. Waqtigan xaadirka ah, baytariyada tamarta sare waxay ku jiraan baahi badan iyo sahayda ku filan, sidaas darteed baytariyada tamarta sare waa adag tahay in la iibsado. Haddii ay dhacdo in uu yaraado batari danabkiisu sarreeyo, way ka raqiisan tahay in la isticmaalo hababka baytariga danab yar.

Qalab-rogayaasha isku-dhafka ah ee soo-saareyaasha waaweyn ee gudaha waxay ku habboon yihiin nidaamyada ka-baxsan-korontadda sababtoo ah wax-soo-saarkooda korantada inta lagu jiro korontadu ma xaddidna. Korantada kaydka ah ee alaabada qaar ayaa waxyar ka hoosaysa xadka caadiga ah, laakiinKorantada kaydka ah ee alaabta cusub ee Goodwe, Jinlang, Sungrow, iyo Hemai waxay la mid tahay qiimaha caadiga ah, taas oo ah, korontadu maaha mid xaddidan marka ay ka baxsan tahay shabakadda, sidaas darteed alaab-qeybiyeyaasha kaydinta tamarta ee warshadeeyayaasha gudaha waxay ku habboon yihiin nidaamyada ka baxsan.

Inverter-ku-xidhan AC
Nidaamyada DC-ku-xidhan maaha kuwo ku habboon dib-u-habaynta nidaamyada hadda jira. Habka isku xidhka DC wuxuu inta badan leeyahay dhibaatooyinka soo socda: Marka hore, nidaamka isticmaalaya isku xidhka DC wuxuu leeyahay dhibaatooyin xagga fiilooyinka adag iyo naqshadaynta moduleka marka wax laga beddelayo nidaamka hadda jira ee isku xidhan; labaad, daahitaanka beddelka u dhexeeya grid-kuxiran iyo off-grid waa dheer, taas oo ay adag tahay isticmaalayaasha. Khibrada korontadu waa liidata; Saddexaad, hawlaha xakamaynta caqli-galku maaha kuwo dhammaystiran oo ku filan jawaab-celinta xakamaynta maaha mid ku filan, taas oo adkeynaysa in la hirgeliyo codsiyada microgrid ee korontada guriga oo dhan. Sidaa darteed, shirkadaha qaarkood waxay doorteen waddada tignoolajiyada isku xirka AC, sida Yuneng.
Nidaamka isku xirka AC wuxuu fududeeyaa rakibidda alaabta. Yuneng wuxuu garwaaqsadaa socodka tamarta laba-geesoodka ah isagoo isku xiraya dhinaca AC iyo nidaamka sawir-qaadista, baabi'inta baahida loo qabo helitaanka baska sawirkavoltaic DC, samaynta rakibidda alaabta mid sahlan; waxay ku ogaanaysaa is dhexgalka ka-baxsan iyada oo loo marayo isku-darka kontoroolka-waqtiga dhabta ah ee software iyo hagaajinta naqshadaynta qalabka Millisecond-beddelashada; iyada oo loo marayo xakamaynta wax soo saarka ee beddelka kaydinta tamarta iyo naqshadaynta cusub ee isku dhafan ee tamarta iyo nidaamka qaybinta, codsiga microgrid ee korontada guriga oo dhan ee hoos yimaada xakamaynta sanduuqa xakamaynta tooska ah waa la xaqiijiyay.
Waxtarka ugu badan ee wax ka beddelka alaabada AC-ku-xidhan yahay ayaa waxyar ka hooseeya kuwa rogayaasha isku-dhafan. Jinlong iyo GoodWaxa kale oo aanu geynay alaabada AC-ku-xidhan, oo inta badan lagu beegsanayo suuqa isbeddelka saamiyada. Waxtarka ugu badan ee wax ka beddelka badeecadaha AC-ku-xidhan yahay waa 94-97%, taas oo waxyar ka hoosaysa ta beddelayaasha isku-dhafan. Tani waxay u badan tahay sababtoo ah qaybaha waa inay maraan laba beddelaad ka hor inta aan lagu kaydin bateriga ka dib markii ay dhalinayaan koronto, taas oo yaraynaysa waxtarka beddelka.
