E-USA: I-PG&E izokwakha isitoreji se-Li-Ion esivela e-Tesla, iNorthWestern ibheja ngegesi

Sawubona, bangane! Esihlokweni "I-Lithium-ion UPS: yiluphi uhlobo lwamabhethri ongalukhetha, i-LMO noma i-LFP?" sithinte udaba lwezixazululo ze-Li-Ion (imishini yokugcina, amabhethri) yezinhlelo zamandla emikhakheni ezimele nezimboni. Nginikeza ukuhumusha kwesifinyezo sezindaba zakamuva ezimfushane ezivela e-United States zangomhla zi-3 Mashi 2020 ngalesi sihloko. Isihloko salezi zindaba siwukuthi amabhethri e-lithium-ion ezinhlaka ezihlukahlukene ezinhlelweni ezimile ashintsha kancane kancane izixazululo ze-lead-acid zakudala, futhi uTesla wenze umnikelo obalulekile. Umkhuba wokusebenzisa izimoto zikagesi wenza kube nokwenzeka ukuthatha amathemba amahle kakhulu nokuphepha kwezixazululo ze-lithium zezinhlelo zamandla kanye nemishini yezimboni ezifana ne-UPS kanye nezinhlelo zokusebenza zamanje (DC) eziqondile. Lezi zixazululo zibizwa ngokuthi amabhethri anamandla amakhulu (Amabhethri Anamandla Aphezulu) ngesi-Russian; emibhalweni yesiNgisi leli igama elithi Energy Storage System-ESS. Okokuqala, ake sihlole isimo ezweni lenkampani ka-Elon Musk; esikhathini esizayo, sizoqhubeka nokushicilela lesi sihloko ngokuhlelekile, ngoba "izindaba ezivela ensimini" zifika ngokushesha okukhulu.

Enye yamaphrojekthi wesitoreji sesistimu enamandla kakhulu egunyazwe i-PG&E

I-Monterey County Planning Commission (Central California, USA - inothi lombhali) igunyaze iphrojekthi yesistimu yokugcina amandla engu-182,5 MWh engu-730 MWh enkulu ebizwa ngokuthi. Elkhorn Battery Energy Storage System ye-Pacific Gas and Electricity (PG&E), ezotholakala e-Moss Landing, California. I-Behemoth ingenye yamaphrojekthi amane abalulekile wokugcina amandla ahlongozwa okokuqala e-California's South Bay yi-PG&E ngoJulayi 2018. Imaphi amabhethri azosetshenziswa lolu hlelo? I-Tesla Megapacks. Ngaphezu kwalokho, i-Elkhorn akuyona enkulu kunazo zonke ezine ezinikezwayo. Okuhamba phambili kufanele kube iphrojekthi ehlongozwayo kodwa engakagunyazwa ye-Dynegy-Vistra enamandla angu-300 MW, 1200 MWh. Futhi uma u-Elkhorn engabandakanyi izidingo zokugcinwa kwamandla kugridi yamandla, ukuqhubeka kwephrojekthi kanye nezinqumo ezinhle kuyisiphetho esingaphambili.

Umlawuli we-Montana uthi iNorthWestern ayilungile kumandla avuselelekayo

Umeluleki we-Montana regulator uqobo uthi uhlelo lwezinsiza zeNorthWestern alulungile kulanga, umoya kanye nesitoreji: Uhlelo lwensizakalo lokusebenzisa imali ecishe ibe yizigidi eziyizinkulungwane zamaRandi ezimbonini zegesi "lwayisiphetho ebesingaziwa" uma kunikezwe ukukhetha kwemodeli yokuthuthukisa imboni "ethanda izinsiza ezishisayo kunezokuvuselelwa kabusha. kanye nezindawo zokugcina,” kusho yena "ucwaningo" kumeluleki we-Synapse Energy Economics. Ngaphezu kwalokho, ukubala okungalungile okuningi "okubi" ekuthengweni kwezinsiza zensiza "kukhawulela ikhono lezinsiza ukuncintisana ukuhlangabezana nezidingo zaseNyakatho-ntshonalanga," kusho ucwaningo.

I-Montana Public Utilities Commission iqashe i-Synapse ukuthi ihlole imizamo yokuhlela ye-NorthWestern Energy. I-Synapse inokufinyelela okulinganiselwe kumodeli "PowerSimm" (Umkhiqizo wesofthiwe/inkundla yokuhlaziya ephelele yokuhlela iphothifoliyo yamandla, ukunwetshwa kwamandla kanye nokuhlaziywa kwezimali - inothi lombhali) INorthWestern futhi ayizange ibe nokufinyelela kokwenza amamodeli ayo agijimayo. Ikwindla edlule "Sierra Club"(inhlangano yezemvelo e-USA, eyasungulwa ngo-1892 - inothi lombhali), esola ukumodela okuchemile eNorthWestern, "ucele ukufinyelela" kufayela lemodeli yosizo.

I-SolarEdge yethula isilawuli senethiwekhi esisha

Firm "SolarEdge" yethule isixazululo esisha sama-inverters, esibizwa "Isilawuli Sesayithi", ithuluzi lokuphatha umthwalo ngesikhathi sokuhluleka kwesistimu yamandla. Isilawuli sesayithi sishintsha i-inverter siye kwenye imodi yomthombo wamandla ngesikhathi esisodwa ekhulisa ukukhiqizwa kwamandla elanga futhi siyigcwalise ngamandla asuka kujeneretha kadizili lapho kudingeka ukuze kuhlangatshezwane nesidingo samandla esizeni, kuyilapho sinikeza nokuvikela ukugcwala ngokweqile. Kalula nje, isilawuli sivumela abanikazi bezindlu ukuthi bahlanganise kalula imithombo yamandla eminingi njengoba beyidinga ngesikhathi sokucima, ngokuphehlwa kwamandla elanga kube umthombo oyinhloko. Isakhiwo sesistimu siboniswe ngezansi. Umthombo: SolarEdge

Idolobha lokuqala laseMelika elinelanga

Isiphetho sephupho lomdlali wangaphambili we-NFL kanye nesivumelwano esikhulu kunazo zonke sokongiwa komhlaba esifundazweni sase-Florida, i-Babcock Ranch iwumphakathi wamahektha angu-18 ophethe umqhele njengedolobha lokuqala nelilodwa elinokukhanya kwelanga eMelika. Idolobha linikwe amandla angu-000MW wamandla elanga, isikhungo samandla elanga "Babcock_Ranch",Florida, kuhlanganiswe nesikhungo sebhethri esingu-10 MW, 40 MWh esisetshenziswa yiFlorida Power and Light. Lo gesi unika amandla ezindlini ezingama-500, nakuba umbono womdali uSid Keetman uwukwandisa lesi sibalo sifike ku-19 000. Idolobhakazi liphinde libe nokufakwa kwelanga ezindlini eziningi nezakhiwo zezentengiselwano, kuyilapho zonke izindlu ezintsha zixhunywe ngamandla kagesi. I-Babcock Ranch nayo ineziteshi eziningi zokushaja izimoto zikagesi. Ungafunda udaba olugcwele lukaLavanya Sunkara mayelana nokuvakasha kwakhe edolobheni esihlokweni "Forbes". Ungafunda futhi izinto zombhali ku-Linkedin, "Mark Wilkerson" (UMark Wilkerson), umcwaningi wamandla elanga oneminyaka engama-34 ohlela ukuthuthela eBabcock Ranch.
