AC blok je popolnoma integriran izdelek za shranjevanje energije z baterijami, ki združuje baterijske module, BMS, upravljanje temperature in PCS (sistem za pretvorbo moči) v eno enoto. Za razliko od DC blokov, ki zahtevajo zunanji pretvornik, AC blok neposredno oddaja izmenični tok, združljiv z omrežjem. Za nabavne ekipe ta celostna arhitektura poenostavi integracijo sistema, zmanjša število dobaviteljskih razmerij in zmanjša kompleksnost BoP.
AC bloki se najpogosteje uporabljajo v aplikacijah C&I in manjših projektih utility-scale, kjer sta preprostost in hitra zagonska faza prednostni. Za velike projekte ločena nabava DC blokov in PCS ponuja več arhitekturne prilagodljivosti in boljše pogajalske pozicije.
Ključne specifikacije
Kaj primerjati pri ocenjevanju AC blokov
Pri predizbiranju za projekt BESS so to ključne tehnične specifikacije, ki jih podjetja EPC, razvijalci projektov in sistemski integratorji običajno ocenjujejo:
C-rate
0,25C – 1C
Določa največjo moč polnjenja/praznjenja glede na kapaciteto. Večina AC blokov je zasnovanih za 0,5C, kar uravnoteži zmogljivost in življenjsko dobo.
Energijska kapaciteta
215 kWh – 10 MWh
AC bloki pokrivajo širok razpon — od enot C&I (215 kWh) do kontejnerjev utility-scale (10 MWh). Optimalna velikost je odvisna od aplikacije in arhitekture sistema.
Kemija
LFP prevladuje
LFP je standardna kemija za AC bloke zaradi varnostnega profila in ciklične življenjske dobe. Nekateri izdelki C&I uporabljajo NMC, ko je zahtevana višja energijska gostota.
Skupna izkoristkovnost cikla
85 – 92 %
Izkoristkovnost merjena na AC strani, vključno z izgubami PCS. Običajno nekoliko nižja od sistemov DC blok + PCS, ker vgrajeni PCS ne deluje vedno v optimalni delovni točki.
Način hlajenja
Tekočinsko ali zračno
Večji AC bloki utility-scale vse pogosteje uporabljajo tekočinsko hlajenje. Manjše enote C&I običajno uporabljajo zračno hlajenje.
Certifikati
UL 9540A, IEC 62619
Enaki osnovni certifikati kot za DC bloke. Ker ima AC blok vgrajen PCS, mora dodatno izpolnjevati zahteve za priključitev na omrežje (npr. Sistemska obratovalna navodila ELES) na ravni sistema.
Pogosta vprašanja
Pogosta vprašanja
Kakšna je razlika med AC blokom in DC blokom?
AC blok združuje baterijo in PCS v eno enoto in neposredno oddaja izmenični tok. DC blok vsebuje samo baterijo, BMS in upravljanje temperature — za priključitev na omrežje zahteva ločen zunanji PCS. AC bloki poenostavijo integracijo; DC bloki ponujajo več arhitekturne prilagodljivosti.
Kdaj izbrati AC blok namesto DC bloka?
AC bloki so posebej primerni za aplikacije C&I, manjše projekte utility-scale in situacije, kjer sta hitra zagonska faza, manjša kompleksnost dobaviteljev in minimalen BoP pomembnejša od polne arhitekturne prilagodljivosti. Za velike projekte utility-scale (50+ MWh) večina razvijalcev raje izbere DC bloke z ločenim PCS za neodvisno optimizacijo nabave in zasnove sistema.
Katere certifikate mora imeti AC blok?
AC bloki potrebujejo enake osnovne certifikate kot DC bloki (UL 9540A, IEC 62619) ter dodatne akreditacije za vgrajeni PCS, vključno s skladnostjo z omrežnimi kodeksi (Sistemska obratovalna navodila ELES) in varnostjo močnostne elektronike (IEC 62477). Ker je AC blok popolnoma integrirana enota, morajo preskusi sistema pokrivati medsebojno delovanje vseh komponent.
Kakšen je tipičen razpon kapacitete AC blokov?
AC bloki segajo od približno 215 kWh (kompaktne enote C&I) do več kot 10 MWh (kontejnerski izdelki utility-scale). Večina AC blokov C&I se giblje med 200 kWh in 1 MWh, medtem ko variante utility-scale običajno ponujajo 3–10 MWh na enoto. Izbira je odvisna od velikosti projekta, omejitev lokacije in želene arhitekture sistema.
