Imakethe yesitoreji samandla ebhethri ikhula kusukela enkingeni eyisisekelo yokungafani kwamandla avuselelekayo: amaphaneli elanga akhiqiza ugesi lapho kukhanya ilanga, izinjini zomoya ziyajikeleza lapho kuheleza umoya, kodwa isidingo siphakama ngamahora ahlukene. Amabhethri avala leli gebe lesikhashana, okwenza amandla ahlanzekile ngezikhathi ezithile athembeke ngokwanele ukuze athathe indawo yezinto zokubasa ezimbiwa phansi.
I-Renewable Energy Integration Imperative
Ukwengezwa kwamandla avuselelekayo emhlabeni wonke kuphindeke kabili phakathi kuka-2020 no-2024, lapho ilanga nomoya manje sekumele iningi lokuphehlwa kukagesi okusha. Lokhu kusheshisa kudale inselelo ephuthumayo yengqalasizinda. Amagridi kagesi endabuko aklanyelwe ukukhiqizwa okubikezelwe, okungahanjiswa okuvela ezitshalweni zamalahle nezegesi yemvelo. Imithombo evuselelekayo yethule ukuntengantenga ingqalasizinda ekhona engeke ikuphathe iyodwa.
I-Texas yabonisa lokhu kuguquguquka ngo-2024: ngemva kokwengeza ama-gigawatts omthamo webhethri entsha, umbuso wakhipha izingcingo zokongiwa kweqanda eziyiziro phakathi nehlobo naphezu kokushisa okurekhodiwe, uma kuqhathaniswa nezingcingo zokongiwa kwe-11 ngo-2023. Amabhethri amunca ukukhiqizwa kwelanga okweqile phakathi nemini futhi akhishwa phakathi nenani eliphakeme lakusihlwa, aguqula ngokuphumelelayo izinsiza zesikhashana zibe umthamo othembekile.
Ama-opharetha egridi abhekene nenkinga ethile yobuchwepheshe: ukugcina imvamisa ngaphakathi kwemingcele ewumngcingo (ngokuvamile i-59.95-60.05 Hz eNyakatho Melika). Uma ukukhiqiza nesidingo kuphelelwa ukuvumelanisa, imvamisa iyachezuka, okungase kubangele ukucisha kukagesi.

Lawa mandla esikhashana ahlukene ayasebenzisana, kwesinye isikhathi aqinise futhi kwesinye isikhathi adale ukungaboni ngaso linye kwesikhashana okwakha inguquko yemakethe.
imibuzo ejwayelekile ukubuzwa
Imaphi amaphesenti amaphrojekthi wamandla avuselelekayo ahlanganisa ukugcinwa kwebhethri?
Ngaphezulu kwesigamu somthamo webhethri ezimakethe ezinkulu njenge-California ixhumeka ngokuqondile kumapulazi elanga noma omoya, okungaba{0}}njengamasistimu akhona noma izinsiza ezihlanganisiwe ezihlanganisiwe. Lesi sabelo siyenyuka ezimakethe ezinegunya lokuhlanganisa elivuselelekayo kodwa liyahluka kakhulu ngokwesifunda nohlobo lwephrojekthi.
Amasistimu okugcina amabhethri ayenza kanjani imali?
Ama-opharetha webhethri ngokuvamile anqwabelanisa ukusakazwa kwemali engenayo okuningi: i-arbitrage yamandla (ukuthenga okuphansi, ukuthengisa okuphezulu), izinsizakalo zokulawula imvamisa, izinkokhelo zamandla, impumuzo yokuminyana kokudlulisela, kanye nokushintshwa kwamandla avuselelekayo. Amamodeli emali engenayo ancike kakhulu ezinhlakeni zezimakethe zesifunda kanye nezinhlaka zokulawula, nezimakethe ezingalawulwa ngokuvamile ezinikeza amathuba engeziwe amaphrojekthi omthengisi.
Kwenzekani ekugcinweni kwebhethri lapho ukunikezwa kwe-lithium kuphelelwa isikhathi?
Obunye ubuchwepheshe obusebenzisa insada yezinto-zesodium-ion, amabhethri agelezayo, isitoreji samandla adonsela phansi{2}}azuza amandla emakethe. Imboni ihlukanisa amakhemikhali kunokuncika ku-lithium kuphela. Ukwengeza, ukugaywa kabusha kwebhethri kuzokwengeza kakhulu ukukhiqizwa kwezimbiwa phansi njengoba imikhumbi efakiwe ikhula.
Kungani ukugcinwa kwebhethri kuvele kungazelelwe ngo-2023-2024?
Ukusheshisa kube umphumela wokuhlangana kwezinto eziningi: Umthetho Wokuncishiswa Kokwehla Nokwehla kwamandla emali wango-2022 unikeze amakhredithi entela angama-30% okugcinwa okuzimele, amanani ebhethri ehle ngo-40% ngo-2024 kuphela, futhi umthamo ovuselelekayo wafinyelela emazingeni lapho abaqhubi begridi bebhekane nezinselele eziphuthumayo zokuhlanganisa. Lawa mashifu akanye adala iphoyinti esikhundleni sokuziphendukela kwemvelo kancane kancane.
Indlela eya Phambili
