Ukubambisana phakathi kwamasethi ejenereyitha kadizili kanye nezinhlelo zokugcina amandla kuyisisombululo esibalulekile sokuthuthukisa ukuthembeka, umnotho, kanye nokuvikelwa kwemvelo ezinhlelweni zamandla zesimanje, ikakhulukazi ezimweni ezifana nama-microgrid, imithombo yamandla eyisipele, kanye nokuhlanganiswa kwamandla avuselelekayo. Okulandelayo yizimiso zokusebenza ngokubambisana, izinzuzo, kanye nezimo ezijwayelekile zokusetshenziswa kwalokhu okubili:
1, indlela yokubambisana eyinhloko
Ukushefa Okuphakeme
Isimiso: Uhlelo lokugcina amandla luyashaja ngezikhathi zokusetshenziswa kukagesi okuphansi (kusetshenziswa ugesi oshibhile noma amandla amaningi avela ezinjinini zikadizili) futhi lukhipha ngesikhathi sokusetshenziswa kukagesi okuphezulu, okunciphisa isikhathi sokusebenza komthwalo ophezulu wamajeneretha kadizili.
Izinzuzo: Nciphisa ukusetshenziswa kukaphethiloli (cishe ngo-20-30%), nciphisa ukuguguleka kweyunithi, futhi wandise imijikelezo yokulungisa.
Ukukhipha okubushelelezi (Ukulawula Izinga Lokukhuphuka)
Isimiso: Uhlelo lokugcina amandla lusabela ngokushesha ekushintsheni komthwalo, okukhokhela ukushiyeka kokubambezeleka kokuqala kwenjini kadizili (ngokuvamile imizuzwana eyi-10-30) kanye nokubambezeleka komthethonqubo.
Izinzuzo: Gwema ukuyeka ukuqalisa izinjini zedizili njalo, gcina imvamisa/i-voltage izinzile, ifanele ukuhlinzeka ngamandla emishinini enembile.
Ukuqala Okumnyama
Isimiso: Uhlelo lokugcina amandla lusebenza njengomthombo wokuqala wamandla wokuqalisa ngokushesha injini yedizili, ukuxazulula inkinga yezinjini zedizili zendabuko ezidinga amandla angaphandle ukuze ziqale.
Inzuzo: Thuthukisa ukuthembeka kokunikezwa kukagesi okuphuthumayo, okulungele izimo zokwehluleka kwegridi kagesi (njengezibhedlela nezikhungo zedatha).
Ukuhlanganiswa Okuvuselelekayo Okuhlanganisiwe
Isimiso: Injini kadizili ihlanganiswe namandla e-photovoltaic/omoya kanye nesitoreji samandla ukuze kuzinziswe ukuguquguquka kwamandla avuselelekayo, kanti injini kadizili isebenza njengesipele.
Izinzuzo: Ukonga uphethiloli kungafinyelela ngaphezu kuka-50%, kunciphisa ukukhishwa kwekhabhoni.
2, Amaphuzu ayisihluthulelo okucushwa kobuchwepheshe
Izidingo zokusebenza kwezingxenye
Isethi yejenereyitha kadizili idinga ukusekela imodi yokusebenza kwemvamisa eguquguqukayo futhi ivumelane nohlelo lokushaja nokukhipha amandla lokugcina amandla (njengokuthathwa yisitoreji samandla lapho ukunciphisa umthwalo okuzenzakalelayo kungaphansi kuka-30%).
Uhlelo lokugcina amandla (i-BESS) lubeka phambili ukusetshenziswa kwamabhethri e-lithium iron phosphate (ahlala isikhathi eside futhi ephephile kakhulu) kanye nezinhlobo zamandla (njenge-1C-2C) ukuze kubhekane nemithwalo yesikhathi esifushane yomthelela.
Uhlelo lokuphatha amandla (i-EMS) ludinga ukuba ne-logic yokushintsha amamodi amaningi (igridi exhunyiwe/engaxhumekile kugridi/ehlanganisiwe) kanye nama-algorithms okusabalalisa umthwalo aguqukayo.
Isikhathi sokuphendula se-bidirectional converter (PCS) singaphansi kwama-20ms, sisekela ukushintsha okungenamthungo ukuvimbela amandla abuyela emuva enjinini kadizili.
3, izimo ezijwayelekile zohlelo lokusebenza
Igridi encane yesiqhingi
Injini ye-photovoltaic + diesel + isitoreji samandla, injini yedizili iqala kuphela ebusuku noma ezinsukwini ezinamafu, kunciphisa izindleko zikaphethiloli ngaphezu kuka-60%.
Ukunikezwa kwamandla okusekelayo kwesikhungo sedatha
Indawo yokugcina amandla ibeka phambili ukusekela imithwalo ebalulekile imizuzu emi-5-15, ngokunikezwa kwamandla okwabiwe ngemva kokuba injini yedizili iqalile ukugwema ukucima kukagesi okwesikhashana.
Ukunikezwa kukagesi emayini
Indawo yokugcina amandla ingabhekana nemithwalo yokushayisana efana nemishini yokumba, futhi izinjini zedizili zisebenza kahle kakhulu (isilinganiso somthwalo esingu-70-80%).
4, Ukuqhathanisa Kwezomnotho (Ukuthatha Uhlelo lwe-1MW Njengesibonelo)
Izindleko zokuqala zohlelo lokucushwa (10000 yuan) Izindleko zokusebenza nokugcinwa konyaka (10000 yuan) Ukusetshenziswa kukaphethiloli (L/ngonyaka)
Isethi yejenereyitha yedizili emsulwa 80-100 25-35 150000
Isitoreji sikadizili+samandla (ukusika ushevu okuphezulu okungu-30%) 150-180 15-20 100000
Umjikelezo wokusebenzisa kabusha: ngokuvamile iminyaka emi-3-5 (uma intengo kagesi iphakeme, kulapho ukuphinda usebenzise kabusha kushesha khona)
5, Izinyathelo Zokuqapha
Ukuhambisana kwesistimu: Umphathi wenjini kadizili udinga ukusekela ukulungiswa kwamandla okusheshayo ngesikhathi sokungenelela kokugcina amandla (njengokwenziwa ngcono kwamapharamitha e-PID).
Ukuvikelwa kokuphepha: Ukuze kuvinjelwe ukugcwala ngokweqile kwenjini kadizili okubangelwa ukugcina amandla ngokweqile, kudingeka kubekwe indawo eqinile yokuvala ye-SOC (State of Charge) (njengo-20%).
Ukusekelwa kwenqubomgomo: Ezinye izifunda zinikeza uxhaso lwesistimu ehlanganisiwe ethi “injini kadizili+ukugcina amandla” (njengenqubomgomo entsha yokuhlola yokugcina amandla yaseShayina ka-2023).
Ngokucushwa okunengqondo, inhlanganisela yamasethi ejenereyitha kadizili kanye nesitoreji samandla ingafinyelela ukuthuthukiswa kusuka "ekusipeleni okumsulwa" kuya "esihlakaniphile se-microgrid", okuyisisombululo esisebenzayo sokushintsha kusuka kumandla endabuko kuya kwe-carbon ephansi. Umklamo othize udinga ukuhlolwa ngokuphelele ngokusekelwe ezicini zomthwalo, amanani kagesi endawo, kanye nezinqubomgomo.
