AC plokk on täisintegreeritud akuenergia salvestustoode, mis koondab akumoodulid, BMS-i, soojusjuhtimise ja PCS-i (võimsusmuundussüsteem) ühte üksusesse. Erinevalt DC plokkidest, mis vajavad välist muundurit, annab AC plokk otse võrguga ühilduvat vahelduvvoolu. Hankemeeskondadele lihtsustab see kõik-ühes-arhitektuur süsteemiintegreerimist, vähendab tarnijasuhteid ja vähendab BoP-keerukust.
AC plokke kasutatakse kõige sagedamini C&I rakendustes ja väiksemates utility-scale projektides, kus lihtsus ja kiire kasutuselevõtt on prioriteetsed. Suurte projektide jaoks pakub DC plokkide ja PCS-i eraldi hankimine suuremat arhitektuurilist paindlikkust ja paremat läbirääkimispositsiooni.
Peamised spetsifikatsioonid
Mida võrrelda AC plokkide hindamisel
Eelvaliku tegemisel BESS-projekti jaoks on need peamised tehnilised spetsifikatsioonid, mida EPC-ettevõtted, arendajad ja süsteemiintegraatorid tavaliselt hindavad:
C-rate
0,25C – 1C
Määrab maksimaalse laadimis-/tühjendamisvõimsuse mahutavuse suhtes. Enamik AC plokke on projekteeritud 0,5C jaoks, tasakaalustades jõudlust ja eluiga.
Energiamahutavus
215 kWh – 10 MWh
AC plokid katavad laia vahemiku — C&I üksustest (215 kWh) kuni utility-scale konteineriteni (10 MWh). Optimaalne suurus sõltub rakendusest ja süsteemiarhitektuurist.
Keemia
LFP domineeriv
LFP on AC plokkide standardne keemia tänu ohutusprofiilile ja tsükliressursile. Mõned C&I tooted kasutavad NMC-d, kui nõutakse suuremat energiatihedust.
Edasi-tagasi kasutegur
85 – 92 %
Kasutegur mõõdetud AC poolel, sisaldab PCS-i kadusid. Tavaliselt mõnevõrra madalam kui eraldi DC ploki ja PCS-i süsteemidel, kuna integreeritud PCS ei tööta alati optimaalses tööpunktis.
Jahutusviis
Vedelik- või õhkjahutus
Suuremad utility-scale AC plokid kasutavad üha enam vedelikjahutust. Väiksemad C&I üksused kasutavad tavaliselt õhkjahutust.
Sertifikaadid
UL 9540A, IEC 62619
Samad põhisertifikaadid mis DC plokkidel. Kuna PCS on integreeritud, peab AC plokk lisaks täitma võrguühenduse nõudeid (nt Eleringi võrgueeskiri) süsteemi tasemel.
Korduma kippuvad küsimused
Korduma kippuvad küsimused
Mis vahe on AC plokil ja DC plokil?
AC plokk integreerib aku ja PCS-i ühte üksusesse ning annab otse vahelduvvoolu. DC plokk sisaldab ainult akut, BMS-i ja soojusjuhtimist — see vajab eraldi välist PCS-i võrguühenduseks. AC plokid lihtsustavad integreerimist; DC plokid pakuvad suuremat arhitektuurilist paindlikkust.
Millal tuleks AC plokk eelistada DC plokile?
AC plokid sobivad eriti hästi C&I rakendusteks, väiksemateks utility-scale projektideks ja olukordadeks, kus kiire kasutuselevõtt, väiksem tarnijakeerukus ja minimaalne BoP on olulisemad kui täielik arhitektuuriline paindlikkus. Suurte utility-scale projektide jaoks (50+ MWh) eelistavad enamik arendajaid DC plokke eraldi PCS-iga, et optimeerida hankimist ja süsteemidisaini sõltumatult.
Milliseid sertifikaate peab AC plokil olema?
AC plokid vajavad samu põhisertifikaate mis DC plokid (UL 9540A, IEC 62619) pluss lisakreditiid integreeritud PCS-i jaoks, sealhulgas vastavus võrgueeskirjadele (Eleringi võrgueeskiri) ja jõuelektroonika ohutus (IEC 62477). Kuna AC plokk on täisintegreeritud üksus, peavad süsteemikatsed katma kõigi komponentide koostoimet.
Milline on AC plokkide tüüpiline mahutavusvahemik?
AC plokid ulatuvad ligikaudu 215 kWh-st (kompaktsed C&I üksused) kuni üle 10 MWh (utility-scale konteinertooteid). Enamik C&I AC plokke jääb vahemikku 200 kWh kuni 1 MWh, samas utility-scale variandid pakuvad tavaliselt 3–10 MWh üksuse kohta. Valik sõltub projekti suurusest, paigalduskoha piirangutest ja soovitud süsteemiarhitektuurist.
