Ukubambisana phakathi kwamasethi ejeneretha kadizili nezinhlelo zokugcina amandla kuyisixazululo esibalulekile sokuthuthukisa ukwethembeka, umnotho, nokuvikelwa kwemvelo ezinhlelweni zamandla zanamuhla, ikakhulukazi ezimeni ezifana nama-microgrid, imithombo yamandla eyisipele, nokuhlanganiswa kwamandla avuselelekayo. Okulandelayo yizimiso zokusebenza ngokubambisana, izinzuzo, kanye nezimo ezijwayelekile zohlelo lwalokhu okubili:
1. Indlela yokubambisana eyinhloko
Ukushefa Okuphakeme
Isimiso: Isistimu yokugcina amandla ishaja ngezikhathi zokusetshenziswa kukagesi okuphansi (usebenzisa ugesi wezindleko eziphansi noma amandla ayinsalela aphuma ezinjinini zikadizili) futhi ikhishwa ngezikhathi zokusetshenziswa kukagesi okuphezulu, kunciphisa isikhathi sokusebenza komthwalo ophezulu wamajeneretha edizili.
Izinzuzo: Yehlisa ukusetshenziswa kukaphethiloli (cishe u-20-30%), nciphisa ukuguga nokudabuka, futhi wandise imijikelezo yokulungisa.
Okukhiphayo okubushelelezi (I-Ramp Rate Control)
Isimiso: Uhlelo lokugcina amandla lusabela ngokushesha ekuguquguqukeni kokulayisha, lunxephezela ukushiyeka kokulibaziseka kokuqala kwenjini kadizili (imvamisa imizuzwana eyi-10-30) kanye nokubambezeleka kokulawula.
Izinzuzo: Gwema ukuqala kokumisa njalo kwezinjini zikadizili, gcina imvamisa/i-voltage ezinzile, elungele ukuhlinzeka amandla emishinini enembayo.
Isiqalo Esimnyama
Isimiso: Uhlelo lokugcina amandla lusebenza njengomthombo wamandla wokuqala wokuqalisa ngokushesha injini ye-diesel, ukuxazulula inkinga yezinjini zedizili zendabuko ezidinga amandla angaphandle ukuqala.
Inzuzo: Thuthukisa ukwethembeka kokuphakelwa kwamandla okuphuthumayo, okulungele izimo zokuhluleka kwegridi yamandla (njengezibhedlela nezikhungo zedatha).
I-Hybrid Renewable Integration
Isimiso: Injini kadizili ihlanganiswe namandla e-photovoltaic/womoya kanye nesitoreji samandla ukuze kunzinziswe ukushintshashintsha kwamandla avuselelekayo, kanti injini yedizili isebenza njengesipele.
Izinzuzo: Ukonga uphethiloli kungafinyelela ngaphezu kwama-50%, kunciphise ukukhishwa kwekhabhoni.
2. Amaphuzu abalulekile wokucushwa kobuchwepheshe
Izidingo zokusebenza zengxenye
Isethi yejeneretha kadizili idinga ukusekela imodi yokusebenza kwefrikhwensi eguquguqukayo futhi ivumelane nokushajwa kwesitoreji samandla kanye neshejuli yokukhipha amandla (njengokuthathelwa indawo yokugcina amandla lapho ukuncishiswa komthwalo okuzenzakalelayo kungaphansi kwama-30%).
Isistimu yokugcina amandla (i-BESS) ibeka phambili ukusetshenziswa kwamabhethri e-lithium iron phosphate (anesikhathi eside sokuphila nokuphepha okuphezulu) nezinhlobo zamandla (ezifana no-1C-2C) ukuze zibhekane nemithwalo yesikhathi esifushane yomthelela.
Uhlelo lokuphatha amandla (EMS) ludinga ukuba nendlela yokushintsha yezindlela eziningi (igridi ixhumeke/ivaliwe igridi/ingxubevange) kanye nama-algorithms okusabalalisa umthwalo ashukumisayo.
Isikhathi sokuphendula sesiguquli se-bidirectional (PCS) singaphansi kwama-20ms, sisekela ukushintsha okungenamthungo ukuvimbela amandla ahlehlayo enjini kadizili.
3. Izimo zohlelo lokusebenza ezijwayelekile
I-Island microgrid
I-Photovoltaic+diesel+isitoreji samandla, injini kadizili iqala ebusuku kuphela noma ngezinsuku eziguqubele, yehlisa izindleko zikaphethiloli ngaphezu kuka-60%.
Gcina ukunikezwa kwamandla kwesikhungo sedatha
Isitoreji samandla sibeka phambili ukusekela imithwalo ebalulekile imizuzu engu-5-15, ngokunikezwa kwamandla okwabelwana ngawo ngemva kokuba injini kadizili isiqalile ukugwema ukunqamuka kukagesi kwesikhashana.
Ukunikezwa kwamandla ezimayini
Ukugcinwa kwamandla kungabhekana nemithwalo enomthelela efana nezimba, futhi izinjini zikadizili zisebenza ngokuzinza ebangeni elisebenza kahle kakhulu (70-80% izinga lokulayisha).
4, Ukuqhathanisa Kwezomnotho (Ukuthatha Isistimu engu-1MW Njengesibonelo)
Izindleko zokuqala zohlelo lokumisa (10000 yuan) Izindleko zonyaka zokusebenza nokugcinwa kwazo (10000 yuan) Ukusetshenziswa kukaphethiloli (L/ngonyaka)
Ijeneretha ye-diesel ehlanzekile 80-100 25-35 150000
Udizili+isitoreji samandla (30% ukushefa okuphezulu) 150-180 15-20 100000
Umjikelezo wokugaya kabusha: imvamisa iminyaka emi-3-5 (uma intengo kagesi iphezulu, ukugaywa kabusha kuyashesha)
5. Izinyathelo zokuqapha
Ukuhambisana kwesistimu: Umbusi wenjini ye-diesel udinga ukusekela ukulungiswa kwamandla okusheshayo ngesikhathi sokungenelela kwesitoreji samandla (njengokwenza kahle kwepharamitha ye-PID).
Ukuvikela ukuphepha: Ukuvimbela ukugcwala ngokweqile kwenjini kadizili okubangelwa ukugcinwa kwamandla amaningi, indawo eqinile yokusika ye-SOC (State of Charge) (efana no-20%) idinga ukumiswa.
Ukusekelwa kwenqubomgomo: Ezinye izifunda zihlinzeka ngoxhaso lwesistimu eyingxube “yenjini kadizili+ukugcina amandla” (njengenqubomgomo yaseChina yokuhlola ukugcinwa kwamandla entsha ka-2023).
Ngokucushwa okuphusile, inhlanganisela yamasethi ejeneretha kadizili kanye nokugcinwa kwamandla kungafinyelela ukuthuthukiswa kusuka “kukulondoloza okumsulwa” kuya “ku-smart microgrid”, okuyisixazululo esisebenzayo soguquko olusuka emandleni endabuko luye kwikhabhoni ephansi. Idizayini ethile idinga ukuhlolwa ngokuphelele ngokusekelwe ezicini zokulayisha, amanani kagesi wendawo, nezinqubomgomo.
Isikhathi sokuthumela: Apr-22-2025
