Haɗin kai tsakanin saitin janareta na diesel da ajiyar makamashi

Haɗin kai tsakanin saitin janareta na diesel da tsarin ajiyar makamashi shine muhimmin bayani don inganta aminci, tattalin arziki, da kariyar muhalli a cikin tsarin wutar lantarki na zamani, musamman a yanayin yanayi kamar microgrids, tushen wutar lantarki, da haɗin gwiwar makamashi mai sabuntawa. Waɗannan su ne ƙa'idodin aiki na haɗin gwiwa, fa'idodi, da yanayin aikace-aikace na yau da kullun na biyun:
1. Hanyar haɗin gwiwar Core
Kololuwar aski
Ƙa'ida: Tsarin ajiyar makamashi yana cajin lokacin ƙarancin amfani da wutar lantarki (ta amfani da wutar lantarki mai rahusa ko rarar wutar lantarki daga injunan diesel) da fitar da wuta a lokacin yawan amfani da wutar lantarki, yana rage yawan lokacin aiki na injinan diesel.
Abũbuwan amfãni: Rage amfani da mai (kimanin 20-30%), rage lalacewa da tsagewar naúrar, da tsawaita zagayowar kulawa.
Fitowa mai laushi (Ikon Rate Rate)
Ƙa'ida: Tsarin ajiyar makamashi da sauri yana amsawa ga jujjuyawar kaya, ramawa ga gazawar jinkirin fara injin dizal (yawanci 10-30 seconds) da ƙayyadaddun tsari.
Abũbuwan amfãni: Guji yawan dakatar da injunan dizal, kula da mitoci/ƙarfin wutar lantarki, dace da samar da wutar lantarki zuwa daidaitattun kayan aiki.
Black Start
Ka'ida: Tsarin ajiyar makamashi yana aiki azaman tushen wutar lantarki don fara injin dizal cikin sauri, magance matsalar injunan diesel na gargajiya da ke buƙatar ikon waje don farawa.
Amfani: Inganta amincin samar da wutar lantarki na gaggawa, wanda ya dace da yanayin gazawar wutar lantarki (kamar asibitoci da cibiyoyin bayanai).
Haɗin Haɗin Sabbin Sabunta
Ƙa'ida: An haɗa injin dizal tare da ƙarfin hoto / iska da kuma ajiyar makamashi don daidaita canjin makamashi mai sabuntawa, tare da injin dizal yana aiki azaman madadin.
Abũbuwan amfãni: tanadin mai zai iya kaiwa sama da 50%, yana rage fitar da iskar carbon.
2. Key maki na fasaha sanyi

Saitin janareta na diesel yana buƙatar tallafawa yanayin aiki na mitar mai canzawa da daidaitawa da cajin makamashi da tsara jadawalin fitarwa (kamar ɗaukar nauyi ta hanyar ajiyar makamashi lokacin da raguwar lodi ta atomatik ta ƙasa da 30%).
Tsarin ajiyar makamashi (BESS) yana ba da fifiko ga yin amfani da batir phosphate na lithium baƙin ƙarfe (tare da tsawon rayuwa da aminci mai girma) da nau'ikan wutar lantarki (kamar 1C-2C) don jimre wa nauyin tasiri na ɗan gajeren lokaci.
Tsarin sarrafa makamashi (EMS) yana buƙatar samun dabaru masu sauyawa na yanayi da yawa (grid da aka haɗa / kashe grid / matasan) da algorithms rarraba kaya mai ƙarfi.
Lokacin mayar da martani na mai jujjuyawar bidirectional (PCS) bai wuce 20ms ba, yana goyan bayan sauyawa mara kyau don hana juyar da injin dizal.
3. Yanayin aikace-aikace na al'ada
Tsibiri microgrid
Photovoltaic + injin dizal + ajiyar makamashi, injin dizal yana farawa ne kawai da dare ko a ranakun girgije, yana rage farashin mai da sama da 60%.
Ajiyayyen wutar lantarki don cibiyar bayanai
Adana makamashi yana ba da fifikon tallafawa manyan lodi na mintuna 5-15, tare da raba wutar lantarki bayan injin dizal ya fara don guje wa katsewar wutar lantarki na ɗan lokaci.
Ma'adanin wutar lantarki
Ma'ajiyar makamashi na iya jure nauyin tasirin tasiri kamar masu tonawa, kuma injunan dizal suna aiki da ƙarfi a cikin kewayon inganci mai ƙarfi (ƙimar kaya 70-80%).
4. Kwatanta Tattalin Arziki (Daukar Tsarin 1MW a matsayin Misali)
Farashin farko na tsarin daidaitawa (Yuan 10000) Yawan aiki na shekara-shekara da farashin kulawa (yuan 10000) Amfanin mai (L/shekara)

Sake sake amfani da su: yawanci shekaru 3-5 (mafi girman farashin wutar lantarki, saurin sake amfani da shi)
5. Hattara
Daidaituwar tsarin: Gwamnan injin dizal yana buƙatar goyan bayan daidaitawar wutar lantarki cikin sauri yayin sa hannun ajiyar makamashi (kamar inganta siginar PID).
Kariyar tsaro: Don hana wuce gona da iri na injin dizal da ke haifarwa ta hanyar ajiyar makamashi mai yawa, ana buƙatar saita wuri mai tsauri don SOC (Jihar Caji) (kamar 20%).
Tallafin manufofi: Wasu yankuna suna ba da tallafi ga tsarin “injin dizal + ma’ajiyar kuzari” (kamar sabuwar manufar ajiyar makamashi ta China ta 2023).
Ta hanyar daidaitawa mai ma'ana, haɗuwa da saitin janareta na diesel da ajiyar makamashi na iya samun haɓakawa daga "tsaftataccen madadin" zuwa "smart microgrid", wanda shine mafita mai amfani don sauyawa daga makamashi na gargajiya zuwa ƙananan carbon. Ƙirar ƙayyadaddun ƙirar yana buƙatar ƙididdige ƙima bisa ga halayen kaya, farashin wutar lantarki na gida, da manufofi.
