Mphamvu yosungirako mphamvu-mayankho olumikizira magetsi ongowonjezedwanso amagawidwa m'mitundu iwiri: AC parallel connection ndi DC coupling.
Njira yolumikizira yolumikizira ya AC, monga momwe ikuwonetsedwera pachithunzichi, ikutanthauza zida zolumikizira zamagetsi zamagetsi zongowonjezedwanso-zolumikizidwa, monga zosinthira ma photovoltaic kapena ma turbine turbine converter, zolumikizidwa ndi chosinthira mphamvu yosungiramo mphamvu (PCS) kudzera pa gridi yamagetsi ya AC. Pansi pa mgwirizano wogwirizana ndi kuwongolera kwa EMS, imagwira ntchito monga kumeta nsonga ndi kudzaza zigwa, kuwongolera kulondola kwamtsogolo, komanso kusalaza.
Ubwino waukulu wa AC parallellumikizidwe ziwembu ndi monga njira zosavuta ndi zomveka magetsi pakati pa zipangizo, ntchito decoupling, ndi muyezo kukhazikika kwa zipangizo chitukuko ndi njira kupanga; kuipa kwakukulu ndi kukwera mtengo kwa mizere ndi zida zolumikizidwa, liwiro loyankhira mwachangu lomwe likufunika pa PCS, komanso kutsika kwachangu pakutembenuza mphamvu zingapo.
Ma coupling scheme atha kugwiritsa ntchito bwino ulalo wa DC womwe umapezeka m'makina ambiri amagetsi ongowonjezwdwanso{{0}wolumikizidwa, ndikuwonjezera mwachindunji zida zosungira mphamvu za batri kuti muchepetse kusinthidwa kangapo kwa mphamvu zongowonjezwdwanso. Izi zimathandizira kulumikizana kwa gridi ndi kusungirako mphamvu; imagwiritsanso ntchito mwachindunji gridi yamagetsi yomwe ilipo kale{2}}zida zolumikizidwa ndi tchanelo cholumikizira ma gridi, kuthetsa kufunika kokulitsa zida za AC komanso kuchepetsa ndalama zogulira ma hardware. Komabe, pali kulumikizana pakati pa makina owongolera ndi gridi yamagetsi omwe alipo kale{4}}zolumikizidwa, kukhwina kwake kumadalira njira yowongolerera ma gridi yamagetsi ongowonjezwdzwdwawo poyamba.
Kutengera-gridi ya turbine yamagetsi-yolumikizidwa yolumikizidwa monga chitsanzo, monga momwe zikuwonekera pachithunzichi, nthawi zambiri imakhala AC-DC-AC "kumbuyo-ku-kubwerera" Gridi-mbali yosinthira imagwira ntchito mu DC-modi yowongolera voteji yam'mbali, pomwe chosinthira chakumbali-chimagwira ntchito mowongolera mphamvu ya turbine yamphepo kapena mowongolera ma torque. Awiriwa amasiyanitsidwa ndi mbali ya DC ndipo amawongoleredwa paokha, ndi banki yayikulu ya capacitor kumbali ya DC imagwira ntchito ngati buffer ndi njira yolumikizira. Chifukwa chake, polumikiza mphamvu inayake ya BESS ku mbali ya DC kuti apange makina ophatikizika osungiramo mphepo ndi mphamvu, gululi-mphamvu yolumikizidwa ya makina opangira magetsi imatha kuyendetsedwa bwino ndipo mphamvuyo imatha kusamutsidwa pakapita nthawi, osakhudza kwambiri makina opangira magetsi, makamaka kuwongolera kwa chosinthira chosinthira makina opangira mphepo.
Mfundo yake yoyendetsera bwino ndi motere: Woyang'anira m'deralo amakhazikitsa njira yogwirira ntchito, monga kumeta nsonga ndi kudzaza m'chigwa, kukonza zolosera molondola, kapena kusalaza, ndikugwirizanitsa mfundo zotumizira gululi kuti apange gululi yonse-lamulo lolumikizidwa la mphamvu yolumikizidwa ∑P* ya mphepo-makina osungira panthawi inayake; imayang'anira mphamvu ya turbine yamphepo PNEndi momwe mphamvu yosungiramo mphamvu imakhalira munthawi yeniyeni, ndikuwerengera bwino ndikupanga dongosolo losungira mphamvu kuti lizilipira ndi kutulutsa mphamvu P*BESS:
