Ukushintshela kumandla ahlanzekile emhlabeni wonke kuthinta i-hyperdrive, ngamaphrojekthi elanga nawomoya avela yonke indawo. Kodwa bane-drawback eyodwa ecacile. Zincike esimweni sezulu. Lapho ilanga linamandla, amandla ngokuvamile ayachithwa. Uma liguqubele noma lizolile, ugesi awanele. Lawa majika enza kube nzima ukusebenzisa ilanga nomoya ngezinga elikhulu.
Singakuxazulula kanjani lokhu?
NgoI-Polinovel, sikholelwa ukuthi impendulo ilele kohlakaniphileyo, i-modularAmasistimu Okugcina Amandla Ebhethri (BESS).
Cabanga nge-BESS njengebhange lamandla elikhulu, elihlakaniphile. Igcina amandla engeziwe uma ukukhiqizwa kuphezulu. Ikhipha amandla lapho isidingo sikhuphuka. Ngale ndlela, ixazulula inkinga yezikhawu zomoya namandla elanga.
Kulo mhlahlandlela, sichaza ukuthi amasistimu okugcina amandla ebhethri asebenza kanjani.
Siyini Isitoreji Samandla Ebhethri
Isistimu yokugcina amandla ebhethri yakhiwe ngezinkulungwane zamaseli ebhethri. Iningi lamasistimu ethu alisebenzisayoAmabhethri e-LiFePO4ngoba ziphephile futhi zihlala isikhathi eside. Aisistimu yokugcina amandla ebhethri (BESS)igcina amandla kagesi ukuze isetshenziswe kamuva, isiza ukulinganisa ukunikezwa kwamandla kanye nesidingo kanye nokuzinzisa ukuphuma kwamandla avuselelekayo.
Isebenza kanjani ngempela?
Emgogodleni walo, isistimu yokulondoloza amandla ebhethri isebenza njengesilondolozi samandla esiguquguqukayo phakathi kokukhiqiza nokufunwa.
1.Ukugcina Okuningi
Lapho ilanga likhipha umkhovu etsheni noma kuvunguza umoya, igridi ngokuvamile ithola amandla angaphezu kwalokho engakwazi ukuyiphatha. Esikhundleni sokuyiyeka ichithe, isistimu yokugcina ibhethri ye-LiFePO4 ingamunca amandla amaningi, iwagcine ukuze asetshenziswe kamuva lapho ama-spikes adingekayo noma amanani egridi ephezulu.
2.Ukugcwalisa Izikhala
Uma izinto zizolile noma ugesi udinga ama-spikes, uhlelo luyakhahlela, luphakele lowo ogcine ugesi ubuyele kolayini.
3.Ubuchopho
Ngemuva kwehardware kunesendlalelo{0}}sezinga eliphezulu lokucula laphoI-BMS (Isistimu Yokulawula Ibhethri)kanye ne-EMS (Energy Management System) isebenza ngokuvumelanisa okuphelele.
- II-BMSisebenza{0}njengomqaphi-ophansi, ebuka "ukushaya kwenhliziyo" kweseli ngalinye ukuvimbela ingcindezi, ukulinganisa amandla kagesi, nokugcina izinga lokushisa eliphezulu lilawula.
- IEMSiphatha-isu elikhulu lesithombe{1}}elihlala licubungula idatha ezimweni zegridi nezintengo zemakethe ukuze linqume ngokuqondile ukuthi kuthunyelwa nini amandla e-ROI ehamba phambili.
Lokhu kuvikela{0}}kumaleveli amaningi akugcini nje ngokugcina izibani zikhanya; kuqinisekisa ukuthi ukuthunyelwa kwamandla kokubili kuhlakaniphile futhi kuphephile. Uthola isistimu yebhethri ezinakekela ngokwayo, ethuthukisa ukusebenza{2}}ngesikhathi sangempela kuyilapho uqinisekisa ukuthi awudingi ukukhathazeka mayelana nezingxenyekazi zekhompuyutha eziyisisekelo.
Indlela Isitoreji Sebhethri Esizisiza Ngayo Izinto Ezivuselelekayo
Nansi indlela abavala ngayo lelo gebe:
Ukunciphisa I-Volatility
I-Solar ne-wind output idume kabi "i-choppy"-umzuzu owodwa ukhiqiza ngokweqile, okulandelayo i-cloud bank ishaya bese okukhiphayo kwehla ku-zero. Esikhundleni sokuvumela lokhu kushintshwa kuphazamise igridi yangakini, i-Polinovel'sIsistimu Yesitoreji Samandla Ebhethri (BESS), inikwa amandla amabhethri e-lithium-e-ion athuthukisiwe, isebenza njengesilondolozi.
Zicwilisa amagagasi angazelelwe futhi asheleleze ukugeleza, aguqule insiza eguquguqukayo ibe umfudlana wamandla ozinzile, ongabikezelwa. Kumakhasimende, lokhu kuzinza kusho ukuphazamiseka kwamandla okumbalwa, ukuvikelwa okungcono kwezisetshenziswa ezizwelayo, kanye nezinga eliphezulu lokusebenzisa impahla yawo yelanga noma yomoya.
Amandla "Isikhathi-Ukushintshashintsha"
Kukhona ukungafani kwakudala emhlabeni wamandla: ukukhiqizwa kwamandla elanga ngokuvamile kuphakama emini, kuyilapho indawo yakho ivame ukufinyelela isidingo saso esikhulu sikagesi ntambama noma kusihlwa.
I-BESS ye-Polinovel ixazulula le nselele ngokuhamba kwesikhathi-ngokushintsha ukukhiqizwa kwamandla akho. Igcina amandla elanga engeziwe usuku lonke futhi iwakhiphe phakathi nezikhathi zokufunwa kakhulu, yenza ngempumelelo ukushefa okuphezulu nge-BESS. Lokhu akugcini nje ngokunika amandla amandla okuxazulula izinkinga kodwa futhi kunikeza isabelomali samandla esibikezelwayo, kunciphisa ukuthembela kugridi ngezikhathi ezimba eqolo, futhi ngokuvamile kwehlisa izindleko zokufunwa okuphezulu - ingxenye enkulu yezindleko zensiza yezimboni.

I-Milisecond Grid Support
Izitshalo zamandla endabuko zifana nemikhumbi emikhulu yezimpahla-ethatha unomphela ukusheshisa noma ukwehlisa ijubane.
Amabhethri, nokho, afana{0}}nezimoto zezemidlalo ezisebenza kahle kakhulu. Bangakwazi ukujova noma bamunce amandla ngama-millisecond. Le mpendulo esheshayo "i-shock absorber" esimisa imvamisa yegridi futhi ivimbele uhlobo lwama-voltage flickers olungaphahlaza imishini yezimboni ebucayi.
Ukugwema "Ucupho Lwengqalasizinda"
Ngokuphatha amandla endaweni, unciphisa ingcindezi kumakhebuli amadala nama-transformer.
Lokhu kuvame ukusho ukuthi ungakwazi ukweqa ukuthuthukiswa kwegridi ebizayo noma izinkokhelo "zamandla okuxhumana" ezikhokhiswa izinsiza. Empeleni, wenza ingqalasizinda yakho ekhona isebenze kanzima futhi ihlakaniphe.
Okuzayo-Ukuqinisekisa nge-Scalability
Into eyodwa abantu abaningi abangayinaki ukuthi izidingo zabo zamandla zizoshintsha. Sidizayine i-BESS yethu ukuthi ibe yimodular.
Ukufundwa okuhlobene:Iyini i-Modular Design?
Awudingi ukutshala imali ngaphezulu-ngosuku lokuqala; ungaqala ngalokho okudingayo kanye nomthamo "wesitaki" njengoba indawo yakho ikhula. Kuyindlela evumelana nezimo egcina i-ROI yakho yokuqala iphezulu ngenkathi ushiya umnyango uvulekele ukukhula.
Isitoreji Samandla Ebhethri kokuthi-Izinhlelo Zomhlaba Zangempela
Amasistimu okugcina amandla ebhethriukusiza abasebenzisi kuzo zonke izilinganiso-kusuka ezintweni ezisetshenziswayo kuya ezindlini-bakhulise amandla avuselelekayo, behlise izindleko, futhi bathuthukise ukwethembeka.
Okusetshenziswayo- kanye Negridi-Isitoreji Samandla Esilinganisa
Ngokuhlanganisa izixazululo zokugcina amandla ebhethri ajwayelekile, amapulazi elanga nawomoya, izinsiza, kanye nama-grid operators angakwazi:
- Letha okukhipha amandla okuzinzile nokubikezelwa
- Sekela ukunwetshwa kwamandla okuzayo
- Shifta amandla usuke-enkathini yesidingo ephansi uye enkathini yesidingo{1}ephezulu
- Nikeza ngezinsiza ezibalulekile zokusekela igridi
Isitoreji Samandla Sezimboni Nokukhiqiza
Kubakhiqizi, amanani{0}}okushefa aphakeme kakhulu angafinyelela kumamajini. Izixazululo zethu zokugcina amandla ebhethri ezimbonini:
- Gcwalisa ama-spikes abizayo lapho igridi ibiza kakhulu
- Qinisekisa ukuthi ukukhiqizwa kuyaqhubeka ngaphandle kokuphazamiseka
- Gcina imigqa ihamba ngisho nalapho igridi ivaliwe
Isitoreji Sokuhweba, Indawo yokuhlala kanye Nomphakathi
Amabhizinisi, abanikazi bezindlu, nemiphakathi basebenzisa isitoreji ukuze:
- Yehlisa izikweletu zikagesi ngokunqamula ukusetshenziswa okuphezulu nokusebenzisa amandla ngobuhlakani
- Gcina izibani zikhanya ngesikhathi sokucima ngamandla ayisipele
- Khulisa ukusetshenziswa kwamandla elanga{0}}futhi unciphise ukukhishwa kwekhabhoni
- Bamba iqhaza ezimbonini zamandla abonakalayo futhi ufune{0}}izinhlelo zokusabela
Amathrendi Ezobuchwepheshe Nentuthuko Yekusasa
Amabhethri awafani nakudala. Zihlala isikhathi eside, zibiza kancane, futhi ziba nobuhlakani njalo ngonyaka.

Ukufundwa okuhlobene:Amathrendi ekuthuthukisweni kwesitoreji samandla ebhethri
Sekukonke,isitoreji samandla ebhethrilikhule lisuka ekubeni ithuluzi elisekelayo laya engxenyeni eyinhloko yezinhlelo zamandla zanamuhla.
Ilinganisa ukuphakama nokwehla kwelanga nomoya. Lokhu akusekho nje 'ngokuba luhlaza'; kumayelana nokugcina izibani zikhanya. Sifinyelele iphuzu lapho isitoreji kuwukuphela kwendlela yokwenza amandla ahlanzekile athembeke kugridi engu-24/7.
Sesingene ngokusemthethweni eminyakeni yokugcina-okuvuselelekayo osekulungele ukwenziwa, futhi ukwethembeka esikuthenjiswe iminyaka kugcine kungokoqobo.
Uma usulungele ukuyeka ukuqagela futhi uqale ukuthuthukisa amafa akho avuselelekayo,sithumeleumlayezo. Ake sithole ukusethwa kwesitoreji okwenzelwe wena okuhambisa inaliti yokusebenza kwakho.
