Iyo yakazara Battery Energy Storage System (BESS) inoda kutariswa kune maviri makuru ekuita zviratidzo: imwe ine chekuita nesimba rekuchengetedza simba uye kushandiswa, kureva, zvine chekuita nekugona; uye imwe ine chekuita nekukwanisa kuzadza kana kusunungura simba, kureva, rine chekuita nesimba. Hukama huri pakati pezvinhu zviviri izvi hunowanzo shandiswa kusiyanisa kuti simba rekuchengetedza simba here-rakarerekera kana kuti rine simba-.
Battery simba rekuchengetedza system kugona
Metric iyi inomiririra huwandu hwesimba hunogona kuchengetwa negadziriro yekuchengetera zvinhu, inowanzoratidzwa mumakilowatt-maawa (kWh) kana megawati-maawa (MWh). Ichi ndicho chimwe chezviyero zvakakosha zvesimba rekuchengetedza hurongwa; zvisinei, simba rayo chairo rinoshandiswa rinokanganiswa nekudzika kwebhatiri kwekubuda (DOD) uye kushanda kwehurongwa.
Kugona kweBESS (Battery Energy Storage System) inosimbisa huwandu hwesimba rinogona kubuda kana kushandiswa, iro rakasiyana netsanangudzo yehuwandu hwebhatiri. Kuwanda kwebhatiri kunowanzoreva huwandu hwebhatiri mune mamwe mamiriro ezvinhu (chiyero chekubuda, tembiricha, kupera simba, zvichingodaro), uye inoyerwa nemaampere-maawa (Ah), inomiririra kubatanidzwa kwezvino nekufamba kwenguva.
Bhatiri simba rekuchengetedza system:Maximum system simba
Simba guru rehurongwa rinoratidza huwandu hwekuchaja uye kuburitsa simba rekuchengetedza simba, uye rinowanzo kuratidzwa mu kilowatts (kW) kana megawatts (MW). Ichi chiratidzo chekuita chinotemerwa nedhizaini yedunhu rese guru, kusanganisira bhatiri, DC transmission circuit, PCS, uye AC yekubatanidza, uye kunyangwe kurasikirwa panguva yekushanda nesimba guru (kurasikirwa uku kuchanyanya kushandurwa kuve kupisa), izvo zvinokanganisa dhizaini yekudzora tembiricha system uye zvimwe zvekubatsira midziyo. Masisitimu ekuchengetedza magetsi ane huwandu hwakafanana anogona kuve neakanyanya akasiyana mashandiro nekuda kwekusiyana kwesimba guru; kunyangwe iyo yakafanana simba rekuchengetedza sisitimu ichaona mutsauko wakapetwa mukuita basa nekuda kweakasiyana ekushandisa masimba masimba.
Kana iyo parameter yemagetsi yakakura kana ichienzaniswa nechiyero chemagetsi, senge 1 MW/500 kWh, inodaidzwa kuti simba-mhando yekuchengetedza simba; ukuwo, kana iri 500 kW/1 MWh, inodaidzwa kuti simba-rudzi rwekuchengetedza simba. Naizvozvo, iyo pfungwa yenguva dzimwe nguva inounzwa, senge yekutanga ichinzi 1 MW/0.5 h, uye yekupedzisira se500 kW/2 h.
Battery simba rekuchengetedza sisitimu:Kurasikirwa kwesimba uye kugona
Kushanda kwesimba rekuchengetedza simba kunoratidza kurasikirwa kwesimba panguva yekuchaja uye yekuburitsa. Inogona kunzwisiswa sereshiyo yesimba rakaburitswa nehurongwa kune simba rinobhadhariswa mariri, inozivikanwawo seyekutenderera kushanda zvakanaka. Kurasika uku hakunechekuita chete nemhando yehunyanzvi hwebhatiri rekuchengetedza simba asi zvakare zvinoenderana nezvikamu zvemagetsi senge simba rekushandura system (PCS). Nenzira yakatetepa, kushanda kwehurongwa kunonyanya kuratidza kurasikirwa mudunhu guru panguva yekuchaja uye kuburitsa, kubva kubhatiri, DC bhazi, PCS, uye pakupedzisira kune transformer (kana iripo). Nekudaro, mumashandisirwo einjiniya anoshanda, mashandisirwo emagetsi emidziyo yekubatsira senge tembiricha yekudzora system inowanzobatanidzwa mukurasikirwa kwakazara, nekudaro kukanganisa kushanda kwese.
Mufananidzo: BESS simba rekuenzanisa hukama
Bhatiri simba rekuchengetedza sisitimu: Nhamba yema cycles
Huwandu hwekuchaja-kubuda kwebhatiri kunotara hupenyu hwayo. Musimba rekuchengetedza simba, nekuda kwekukosha kwebhatiri, hupenyu hwayo hunotarawo hupenyu hwese system. Kusvibiswa kwehupenyu hwehupenyu hunoita kuti kuwedzere kupikisa kwemukati, izvo zvinowedzera kurasikirwa uye chizvarwa chekupisa, zvichiwedzera kukurumidza kuparara. Pamusoro pazvo, kugara uchichaja uye{4}}kudonha zvakanyanyisa kunokonzera kuparara kudzokororwa uye kuiswa kwesimbi mu electrolyte, izvo zvinokanganisa zvakanyanya kutenderera kwebhatiri nekuchengetedzeka.
Kune imwe mhando yelithium-ion bhatiri, huwandu hwemacycles ari pasi pe1C yekuchaja uye 1C yekuchaja mamiriro anoratidza mutsauko wakakura pakudzika kwakasiyana kwekubuda (DOD), sezvakaratidzwa pamufananidzo.
Battery simba rekuchengetedza system mutengo
Mutengo wesimba rekuchengetedza masisitimu une hukama zvakanyanya nehukuru hwehurongwa, simba, uye nharaunda yekushandisa. Kazhinji, mumagetsi-masisitimu ekuchengetera emhando, mutengo wemabhatiri unoenderana nemwero wakakwirira; ichiri musimba-masisitimu ekuchengetera mhando, mutengo wemabhatiri wakadzikira. Nekudaro, chero zvazvingava, mutengo webhatiri pack parizvino unoumba chikamu chikuru cheiyo BESS mutengo, uye ichavewo nzvimbo yekutanga yekudzikisa mutengo mune ramangwana.
Chiyero chemutengo chinogona kuratidzwa se yuan/kWh kana yuan/kW, asi kwete zvizere uye nemazvo zvinomiririra zvazvinoreva. Naizvozvo, zvakakosha kudoma zvese kugona uye simba panguva imwe chete panguva yenhaurirano dzemapurojekiti chaiwo.
Bhatiri simba rekuchengetedza system: mutengo wekupindura nguva
Kune BESS (Battery Energy Storage Systems), zvose simba rekushandura uye nguva yekupindura zviri mu millisecond range, iyo inokwana kune simba rekushandisa maitiro. Apa ndipo panokwirira BESS kana zvichienzaniswa nedzimwe nzira dzekuchengeta simba senge flywheel simba rekuchengetedza uye kupomba-simba remvura. Nekudaro, nekuda kwezvipimo mumagetsi, nzira dzekuisa, uye bhatiri cell huwandu, simba uye kugona kweimwe BESS unit ishoma. Naizvozvo, muhombe-magetsi emagetsi ekuchengetedza magetsi, senge anoumbwa akawanda emagetsi mashoma-voltage 5MW/2h masisitimu ekuchengetedza simba akabatana akatevedzana, iyo bhodhoro munguva yekupindura ichanyanya kuganhurirwa nenzira yekukurukurirana uye kuronga masisitimu. Ichakanganiswawo nemabasa akadai sekubatanidza simba uye kutenderera ikozvino kudzvinyirira pakati pemidziyo yakafanana. Yekupedzisira chiteshi{10}}yero yekupindura nguva inogona kunge iri mumazana emamilliseconds kana masekonzi. Zvechokwadi, imwe chete 5MW / 2h BESS unit inongova muenzaniso wekufungidzira; iyo yakawandisa parallel yekubatanidza yemabhatiri pachayo inokonzeresa njodzi dzekuchengetedza. Kugadzirisa dambudziko iri kunoda shanduko yenzira dzekutonga neboka uye mabhindauko nemashandisirwo emagetsi matsva ekuchengetedza simba senge high{15}}voltage direct connection.
Bhatiri simba rekuchengetedza system: Zvimwe zvinhu
Mune zvimwe zviitiko zvemashandisirwo kana ongororo yehupfumi, pfungwa dzakaita sesimba chairo (simba-ku{1}}reshiyo yehuwandu, Wh/kg), simba chairo (simba-ku-reshiyo yehuremu, kW/kg), uye kuwanda kwesimba pachikamu chimwe chete (simba{4}}ku{5}}reshiyo yenzvimbo, Wh/m²) inoshandiswawo. Aya mazano akakodzera pakuverenga mari yekufambisa kweprojekiti uye zvinodiwa zvekushandiswa kwevhu.
