Iyo huru tradeoff ndeye yakaderera simba density, inoda 3-5x yakawanda nzvimbo yemuviri kune imwechete simba kubuda.
Chii chinotarisa kana chishandiso chichifanira kusarudza 2-awa, 4-awa, kana 6-awa yekuchengetedza?
Mhinduro inobva pane dambudziko regridi riri kugadziriswa. Kune frequency regulation uye intraday arbitrage, maawa maviri anokwana. Pakushandura masikati ezuva kugadzirwa kwezuva kusvika manheru, maawa mana anoshanda nemazvo. Kuti usimbise kugadzira mhepo kana kugadzirisa marambi ekutakura mambure munzvimbo dzakakwirira-dzinogonekazve magridi, 6+ maawa anodiwa. Texas ERCOT masisitimu anotsvedza akananga kumaawa 2-4 nekuti mutengo wezuva nezuva unopararira kutyaira hupfumi. California masisitimu anowedzera kushandisa maawa 4-6 nekuti mutemo unoda kubhuroka iyo 3-9 PM kushomeka kwesimba kana kugadzirwa kwezuva kunodonha asi kudiwa kunoramba kwakakwira.
Mabhatiri eEV echipiri-eupenyu echipiri anogoneka mukuchengetedza zvinhu?
Redwood Energy yakaisa 63 MWh yemabhatiri eEV yechipiri-yeupenyu muna 2024, ichiabatanidza ne20 MW yemagetsi ezuva uye data center. Tekinoroji iyi inoshanda nekuti chengetedzo ine mamiriro ekushanda akapfava pane mota dzemagetsi-zvinodiwa simba repasi, tembiricha inodzorwa, kuzunguzika kushoma. Economics inogona kushanda nekuti vekushandisa vanogona kuwana mabhatiri aya ne40-60% zvideredzwa zvichienzaniswa nemasero matsva. Matambudziko makuru mabhatiri manejimendi kuoma (pakeji yega yega ine makemikari akasiyana uye maitiro ekudzikisira) uye nguva inodiwa kuunganidza, kuyedza, uye kubatanidza mabhatiri kubva kwakawanda masosi. Iyo mhinduro ine musoro kune chaiyo maapplication asi haizotsiva chinangwa-yakavakirwa utility chengetedzo pamwero.
Inokurumidza sei matekinoroji ekuchengetedza akasiyana anogona kuiswa?
Lithium-ion inobata rekodhi yekumhanya: 4-mwedzi 12 kubva pamvumo yesaiti kusvika pakushanda kwemasisitimu ari pasi pe200 MW. Tesla's Megablock inogona kuendesa 1 GWh mumazuva makumi maviri ebhizinesi pasi pemamiriro akanaka. Mabhatiri anoyerera anotora 8-mwedzi 18 nekuda kwekugadzirwa kwetangi remagetsi remagetsi. Pumped hydro inoda 6-makore gumi kusanganisira mvumo nekuvaka, zvichiita kuti ishande chete pakuronga grid kwenguva refu. Iyi yekufambisa yekumhanyisa mukana inotsanangura kuti sei 81% yenzvimbo nyowani yekuchengetedza muna 2024 yakashandisa lithium-ion kunyangwe mutengo wayo wepamusoro wehupenyu hwekushandisa kwenguva refu.
Chii chinoitika pakuchengetedza bhatiri kuita mukupisa kwakanyanya?
Lithium-mabhatiri eion anodzikira nekuchimbidza kupfuura 35℃uye kukwanisa kurasikirwa nechiyero chiri pasi pe0℃, zvinoda masisitimu ekudziya nekutonhodza anoshandisa 3-5% yesimba rakachengetwa. Texas masisitimu panguva yaNyamavhuvhu 2024 kupisa wave aifanira kudzikisa kubuda kwemagetsi ne10-15% kudzivirira kupisa kutiza. Mabhatiri anoyerera anoshanda pasina kudzorwa kwemamiriro ekunze kubva -10 dhigirii kusvika 60 dhigirii, uye pumped hydro haina kukanganiswa zvachose nekushisa. Izvi zvinonyanya kukosha kupfuura vazhinji vanoziva-Arizona's 185 MW ekuchengetedza nyowani muna 2024 ichashandisa yakakosha mari yekushandisa pakutonhodza iyo Minnesota kuiswa kwaizoshandisa pakudziya.
