I-Battery Energy Storage System (BESS) iyisistimu yebhethri enkulu esekelwe ekuxhumekeni kwegridi, esetshenziselwa ukugcina ugesi namandla. Ihlanganisa amabhethri amaningi ndawonye ukuze akhe idivayisi edidiyelwe yokugcina amandla.
1. Iseli Yebhethri: Njengengxenye yesistimu yebhethri, iguqula amandla amakhemikhali abe amandla kagesi.
2. Imojula Yebhethri: Ihlanganiswe ngochungechunge oluningi namaseli ebhethri axhumene ngokufanayo, ihlanganisa Imojuli Yesistimu Yokulawula Ibhethri (MBMS) ukuze igade ukusebenza kwamaseli ebhethri.
3. Iqoqo Lebhethri: Isetshenziselwa ukwamukela amamojula axhunywe uchungechunge oluningi kanye namaYunithi Okuvikela Ibhethri (i-BPU), eyaziwa nangokuthi isilawuli seqoqo lebhethri. I-Battery Management System (BMS) yeqoqo lebhethri iqapha amandla kagesi, izinga lokushisa, nesimo sokushaja samabhethri kuyilapho ilawula imijikelezo yawo yokushaja nokushajwa.
4. Isitsha Sokugcina Amandla: Singathwala amaqoqo ebhethri amaningi axhumene ngokufanayo futhi singase sifakwe nezinye izingxenye ezengeziwe zokuphatha noma ukulawula indawo yangaphakathi yesiqukathi.
5. Uhlelo Lokuguqula Amandla (i-PCS): Amandla amanje aqondile (DC) akhiqizwa amabhethri aguqulelwa ku-alternating current (AC) nge-PCS noma iziguquli eziqondiswa kabili ukuze zidluliselwe kugridi yamandla (izinsiza noma abasebenzisi bokugcina). Uma kudingeka, le sistimu ingaphinda ikhiphe amandla kugridi ukuze ishaje amabhethri.
Uyini umgomo wokusebenza we-Battery Energy Storage Systems (BESS)?
Isimiso sokusebenza se-Battery Energy Storage System (BESS) ikakhulukazi sihlanganisa izinqubo ezintathu: ukushaja, ukugcina, nokushajwa. Phakathi nenqubo yokushaja, i-BESS igcina amandla kagesi ebhethrini ngomthombo wamandla wangaphandle. Ukuqaliswa kungaba okwamanje okuqondile noma okushintshanayo, kuye ngomklamo wohlelo kanye nezidingo zohlelo lokusebenza. Uma kunamandla anele anikezwa umthombo wamandla wangaphandle, i-BESS iguqula amandla engeziwe abe amandla amakhemikhali futhi iwagcine kumabhethri aphinde ashajwe ngendlela evuselelekayo ngaphakathi. Phakathi nenqubo yokulondoloza, lapho kungekho ukunikezwa okwanele noma kungekho kwangaphandle okutholakalayo, i-BESS igcina amandla agciniwe ashajwe ngokugcwele futhi igcina ukuzinza kwayo ukuze isetshenziswe esikhathini esizayo. Ngesikhathi senqubo yokukhipha, lapho kunesidingo sokusebenzisa amandla agciniwe, i-BESS ikhipha inani elifanele lamandla ngokwesidingo sokushayela amathuluzi ahlukahlukene, izinjini noma ezinye izinhlobo zemithwalo.
Yiziphi izinzuzo nezinselele zokusebenzisa i-BESS?
I-BESS ingahlinzeka ngezinzuzo namasevisi ahlukahlukene ohlelweni lwamandla, njenge:
1. Ukuthuthukisa ukuhlanganiswa kwamandla avuselelekayo: I-BESS ingagcina amandla amaningi avuselelekayo phakathi nezikhathi zokukhiqiza okuphezulu kanye nesidingo esiphansi, futhi iwakhulule ngezikhathi zokukhiqiza okuphansi kanye nesidingo esikhulu. Lokhu kunganciphisa ukuncishiswa komoya, kuthuthukise izinga lokusebenzisa kwayo, futhi kuqede ukuphumula nokuhlukahluka kwawo.
2. Ukuthuthukisa ikhwalithi yamandla nokwethembeka: I-BESS inganikeza impendulo esheshayo neguquguqukayo ekuguquguqukeni kwe-voltage namafrikhwensi, ama-harmonics, nezinye izindaba zekhwalithi yamandla. Ingase futhi isebenze njengomthombo wamandla oyisipele futhi isekele umsebenzi wokuqala omnyama phakathi nokucisha kwegridi noma izimo eziphuthumayo.
3. Ukunciphisa isidingo esikhulu: I-BESS ingashaja ngamahora okungasebenzi kakhulu lapho amanani kagesi ephansi, futhi iwukhiphe phakathi namahora okusebenza lapho amanani entengo ephezulu. Lokhu kunganciphisa isidingo esikhulu, ukunciphisa izindleko zikagesi, futhi kubambezele isidingo sokunwetshwa kwamandla esizukulwane esisha noma ukuthuthukiswa kokudluliswa kwamandla.
4. Ukunciphisa ukukhishwa kwegesi ebamba ukushisa: I-BESS inganciphisa ukuthembela ekuphehleni okusekelwe kuphethiloli, ikakhulukazi ngezikhathi eziphakeme kakhulu, kuyilapho ikhulisa isabelo samandla avuselelekayo ekuxubeni kwamandla. Lokhu kusiza ukunciphisa ukukhishwa kwegesi ebamba ukushisa kanye nokunciphisa imithelela yokushintsha kwesimo sezulu.
Kodwa-ke, i-BESS iphinde ibhekane nezinselelo ezithile, njenge:
1. Izindleko eziphezulu: Uma kuqhathaniswa neminye imithombo yamandla, i-BESS isabiza kakhulu, ikakhulukazi ngokwezindleko ezinkulu, izindleko zokusebenza nezokulungisa, kanye nezindleko zomjikelezo wokuphila. Izindleko ze-BESS zincike ezintweni eziningi ezifana nohlobo lwebhethri, usayizi wesistimu, uhlelo lokusebenza, nezimo zemakethe. Njengoba ubuchwepheshe buvuthwa futhi bukhuphuka, izindleko ze-BESS kulindeleke ukuthi zehle ngokuzayo kodwa zingase zibe isithiyo ekutholweni okusabalele.
2. Izinkinga zokuphepha: I-BESS ihilela amandla kagesi aphezulu, amandla amanje amakhulu, nezinga lokushisa eliphakeme elibeka izingozi ezingaba khona njengezingozi zomlilo, ukuqhuma, ukushaqeka kukagesi njll. I-BESS futhi iqukethe izinto eziyingozi njengezinsimbi, ama-acids nama-electrolyte angabangela izingozi zemvelo nempilo. uma ingaphathwanga noma ilahliwe ngendlela efanele. Kudingeka amazinga okuphepha aqinile, imithethonqubo kanye nezinqubo zokuqinisekisa ukusebenza okuphephile nokuphathwa kwe-BESS.
5. Umthelela wemvelo: I-BESS ingase ibe nomthelela omubi endaweni ezungezile okuhlanganisa ukucekelwa phansi kwemithombo, izinkinga zokusetshenziswa komhlaba izinkinga zokuphehla udoti, kanye nokukhathazeka kokungcoliswa kwemvelo.I-BESS idinga amanani abalulekile ezinto ezingavuthiwe ezifana ne-lithium, i-cobalt, i-nickel, ithusi njll., I-BESS iphinde isebenzise amanzi nomhlaba ukuze kufakwe ukukhiqizwa kwezimayini, futhi i-operation.BESS ikhiqiza imfucuza kanye nesisi esikhishwayo kuwo wonke umjikelezo wayo wokuphila okungase kuthinte izinga lenhlabathi yamanzi omoya.Imithelela yemvelo idinga ukucatshangelwa ngokuthatha izinqubo ezisimeme ukuze kuncishiswe imiphumela yayo ngangokunokwenzeka.
Yiziphi izinhlelo zokusebenza eziyinhloko nezimo zokusebenzisa ze-BESS?
I-BESS isetshenziswa kabanzi ezimbonini nasekusetshenzisweni okuhlukahlukene, njengokukhiqiza ugesi, izindawo zokugcina amandla, imigqa yokudlulisela nokusabalalisa ohlelweni lwamandla, kanye nezinhlelo zezimoto zikagesi nezasolwandle emkhakheni wezokuthutha. Iphinde isetshenziswe ezinhlelweni zokugcina amandla ebhethri ezindlini zokuhlala nezokuhweba. Lezi zinhlelo zingahlangabezana nezidingo zesitoreji samandla anqwabelene futhi zinikeze amandla okulondoloza ukuze kuncishiswe ukugcwala kakhulu emigqeni yokudlulisela nokusabalalisa kuyilapho kuvimbela ukuminyana ohlelweni lokudlulisela. I-BESS idlala indima ebalulekile kumagridi amancane, asakazwa amanethiwekhi wamandla axhunywe kugridi eyinhloko noma asebenza ngokuzimela. Amagridi amancane azimele atholakala ezindaweni ezikude angathembela ku-BESS ehlanganiswe nemithombo yamandla avuselelekayo ngezikhathi ezithile ukuze azuze ukuphehlwa kukagesi ozinzile kuyilapho esiza ukugwema izindleko eziphezulu ezihlobene nezinjini zikadizili nezinkinga zokungcoliswa komoya. I-BESS iza ngosayizi abahlukahlukene kanye nokucushwa, ilungele kokubili izinto zasendlini ezisezingeni elincane kanye nezinhlelo ezisetshenziswayo ezinkulu. Angafakwa ezindaweni ezahlukene okuhlanganisa amakhaya, izakhiwo zezentengiselwano, neziteshi ezincane. Ukwengeza, zingasebenza njengemithombo yamandla eyisipele esiphuthumayo ngesikhathi sokucisha.
Yiziphi izinhlobo ezahlukene zamabhethri asetshenziswa ku-BESS?
1. Amabhethri aneasidi yomthofu awuhlobo lwebhethri olusetshenziswa kakhulu, oluhlanganisa amapuleti omthofu kanye ne-electrolyte ye-sulfuric acid. Ahlonishwa kakhulu ngenxa yezindleko zawo eziphansi, ubuchwepheshe obuvuthiwe, nokuphila isikhathi eside, ikakhulukazi ezindaweni ezifana namabhethri okuqala, imithombo yamandla ezimeni eziphuthumayo, kanye nesitoreji samandla esincane.
2. Amabhethri e-lithium-ion, okungenye yezinhlobo zamabhethri ezaziwa kakhulu nezithuthukisiwe, aqukethe ama-electrode aqondile noma angalungile enziwe ngensimbi ye-lithium noma izinto eziyinhlanganisela kanye nezincibilikisi eziphilayo. Zinezinzuzo ezinjengokuminyana kwamandla aphezulu, ukusebenza kahle okuphezulu, nomthelela ophansi kwezemvelo; idlala indima ebalulekile kumadivayisi eselula, ezimotweni zikagesi, nezinye izinhlelo zokusebenza zokugcina amandla.
3. Amabhethri agelezayo angamadivayisi okugcina amandla ashajwayo asebenza kusetshenziswa imidiya ewuketshezi egcinwe emathangeni angaphandle. Izici zabo zihlanganisa ukuminyana kwamandla aphansi kodwa ukusebenza kahle okuphezulu nempilo ende yesevisi.
4. Ngaphezu kwalezi zinketho ezishiwo ngenhla, kukhona nezinye izinhlobo ze-BESS ezitholakalayo ongakhetha kuzo njengamabhethri e-sodium-sulphur, amabhethri e-nickel-cadmium, nama-super capacitor; ngayinye inezici ezihlukene nokusebenza okufanele izimo ezihlukahlukene.
