Ennyonyola enzijuvu ku ndowooza y’emirimu awamu n’embeera z’okukozesa ekyuma ky’amasannyalaze ekitereka amaanyi ga bbaatule ya lithium-ion

Akatale k’ekifo awaterekerwa amaanyi naddala akatale k’ekifo awaterekerwa amaanyi ga bbaatule ya lithium-ion, katwalibwa ng’akalina akatale akagazi n’embeera ez’enjawulo ez’okukozesa. Omulimu gw’okutereka amasannyalaze mu bwengula gunywezeddwa pulojekiti eziwerako ku ludda lw’omukutu, mu ngeri y’obusobozi obupya obuteekeddwa wamu n’obunene bw’emitendera. Firimu nnyingi ez’omunda awamu n’ez’ensi yonna eza bbaatule za lithium-ion nazo zikwata ku nkola z’okutereka amaanyi mu kifo (ESS) ng’ennyanja emu endala eya bbululu ng’oggyeeko bbaatule za lithium ez’amaanyi nga kw’otadde n’okuzifulumya n’obunyiikivu.

Enkola y’emirimu gy’ekyuma ekitereka amaanyi ga bbaatule ya lithium-ion

Omusingi gw’emirimu gya loole ezitereka amaanyi ga bbaatule za lithium mu mbeera ey’amangu oba siteegi z’amasannyalaze eziterekebwawo ku ddaala lya megawatt kwe kukyusa butereevu emigugu gya bbaatule za lithium-ion ez’amaanyi amangi okuzifuula amaanyi ga phase emu ne phase ssatu ez’empewo nga tuyita mu inverters. Mu budde obwabulijjo, olina okulonda mu ddembe ekiseera ky’okusasula ssente okusobola okusasula bbaatule. Battery pack ya lithium-ion bw’eba esasulwa ddala, esobola okuyitibwa essaawa yonna. Battery etereka amaanyi kitundu kikulu nnyo mu nkola y’okukola amasannyalaze agava mu njuba okutereka amasannyalaze ate era n’amasannyalaze. Ekikulu kyayo kwe kukuuma amaanyi g’amasannyalaze g’enkola y’okukola amasannyalaze aga photovoltaic oba pv, n’okugabira ttani amaanyi ng’omusana tegumala, ekiro ne mu mbeera ey’amangu.

1. Okusasula ssente

Embeera ey’amangu mmotoka ezitereka amaanyi ga bbaatule ya lithium oba ekyuma ekitereka amasannyalaze agatali gakyukakyuka ku ddaala lya megawatt kiteekeddwa okuba ne sockets 2 ezicaajinga, ezitambula mpola ate nga nazo za mangu. Enkola y’okucaajinga ey’amangu era etali ya maanyi kwe kutereeza obunene bw’obudde bw’okucaajinga ng’olonda amasannyalaze ag’enjawulo ag’okucaajinga. Enkola yonna ey’okucaajinga ekeberebwa enkola ey’amagezi ey’okuddukanya emirimu. Voltage y’ekika kyonna eky’ekisenge ekitali kimu ekya bbaatule ya lithium-ion bw’etuuka ku muwendo ogwateekebwawo, chajingi ya bbaatule ejja kukomya amangu ago okucaajinga kwa bbaatule.

2. Okuyimbula

Loole ezitereka amasannyalaze ag’amangu oba ekyuma ekitereka amasannyalaze agatali gakyukakyuka ku ddaala lya megawatt zikolebwa mu ngeri ey’enjawulo nga zirina enkolagana ezifuluma (mu ngeri entuufu, enkolagana z’ebivaamu ez’amaanyi amangi eza phase ssatu awamu ne sockets z’ebivaamu eza phase emu ez’ennono zikolebwa okusinziira ku byetaago by’abakozesa).

3. Okuddaabiriza

Mu budde obwabulijjo, weetaaga kwekenneenya biraga buli bbaatule yokka ku ssirini y’okulaga enkola y’okuddukanya bbaatule ya lithium-ion, awamu n’obutaddaabiriza mu ngalo kyetaagisa. Enkola y’okuddukanya bbaatule eweebwa ne screen y’obusobozi obumanyiddwa, screen eraga voltage, wamu n’okulaga screen y’ebbugumu lya buli battery yokka ne voltage yaayo entono oba esinga obulungi.

Lithium-ion battery power storage embeera z’okukozesa ekyuma ky’amasannyalaze

Nga embeera y’okukozesa egenda, bbaatule za lithium-ion mu kifo we zitereka amaanyi mu butuufu zizze ziyimiriddewo mpolampola. Ekifo we batereka amaanyi y’emu ku nkola enkulu okugonjoola okukyukakyuka okuddirira okw’amaanyi g’empewo amapya ag’amaanyi awamu n’amasannyalaze g’ekitangaala era n’okutuukiriza omulimu gwa 'okusenya obugulumivu nga kw’otadde n’ebiwonvu ebipapajjo'. Mu nkola ey’amagezi ey’okutereka amaanyi g’amasannyalaze mu nsi yange, ebitundu ebina ebisinga obukulu bye bino: okuyungibwa kw’amasannyalaze agazzibwawo, oludda lw’abakozesa, oludda lw’omukutu era n’empeereza ezijjuliza.

1. Okutereka amasannyalaze embeera ey’amangu ekyuma ekigaba amasannyalaze

Loole y’okutereka amaanyi mu kifo eky’amangu ekolebwa bbaatule ya lithium-ion, inverter, enkola y’okuddukanya bbaatule, n’ebirala. Inverter straight ekyusa battery right mu single-phase nga kwotadde ne three-phase alternating eziriwo. Mu budde obutuufu, olina okulonda mu ddembe obudde bw’okusasula okusobola okucaajinga bbaatule. Battery pack bw’eba ecaajinga ddala, esobola okuyitibwa essaawa yonna mu mwaka gumu, nga kw’otadde n’obutaba na bwetaavu bwa floating cost. Tusobola okugabira 100KW, 1000KW, 5000KW, megawatt-class mobile emergency situation energy storage space lorry, eziyinza okukozesebwa mu kisaawe ky’okukuuma eggwanga era n’amagye, okukendeeza ku bubenje bw’abantu oba emikolo eminene egy’olukale. Ebiseera ebisinga, ejjula ddala amaanyi g’ekiwonvu amatono, nga kw’otadde n’okwetegekera okusindikibwa ebweru okutuuka w’egenda essaawa yonna.

2. Ekifo eky’okutereka amaanyi essundiro ly’amasannyalaze eriyimiridde

Okutereka amaanyi okukolebwako n’ekyuma ky’amasannyalaze kukolebwa bbaatule ya lithium-ion, enkola y’okuddukanya BMS, enkola ya PCS converter, enkola y’okulondoola amaanyi ga EMS, enkola eziwagira (ezirimu okufuga ebbugumu, okukuuma omuliro, n’ebirala), era era nkola ya kifo eky’okutereka amasannyalaze ey’ekika kya siteegi y’amasannyalaze essiddwa mu konteyina. Olw’okuba bbaatule za lithium-ion zirina okukendeeza ku kwefulumya, tezeetaaga kukola mu mbeera ya chajingi ewuguka okumala ebbanga ddene nga bbaatule eza bulijjo eza lead-acid oba nickel-cadmium awamu ne nickel-metal hydride. Ekyuma ky’amasannyalaze mu kifo ekitereka amasannyalaze kigattibwa wamu n’enkola empya ennyo ey’okukola amasannyalaze okujja okuba ensibuko y’amasannyalaze agasaasaanyiziddwa mu micro grid eyetongodde. Kisaanira okuwa amasannyalaze agesigika mu bitundu ebitaliimu masannyalaze oba obutaba na masannyalaze, era era kisobola okugatta ku kuwa peak shifting era n’okujjuza ebiwonvu wamu n’okusenya waggulu ate era regularity law solutions for large power grids.

Ekifo ky’amasannyalaze mu kifo we batereka amaanyi ga bbaatule kisobola okugattibwa n’okukola amasannyalaze amapya agasaasaanyizibwa/aga wakati, nga eno y’emu ku ngeri ennungi ez’okugonjoola ekizibu ky’omukutu gw’amasannyalaze amapya ag’okukola amasannyalaze. Mu butuufu kiwedde nga kiyiiya kinene ekyetaagisa nga kiwagira enkola y’eggwanga lyange ey’okutumbula amasannyalaze amayonjo.

3. Enkolagana back-up amasannyalaze

Akatale k’amasannyalaze ag’okutereka empuliziganya okusinga kalimu ebitundu 2, ekimu kiri nti ekifo we batereka amasannyalaze ga base stations ezaakakolebwa kikola akatale okweyongera buli mwaka; ekirala kiri nti okuggwaako kw’ekiseera nga kw’otadde n’okukyusa bbaatule za base station eziriwo bye bikola obungi obusookerwako obw’akatale buli mwaka. omunaala gw’ekyuma ogw’eggwanga lyange gwayanjula nti mazima ddala tegujja kuddamu kufuna asidi wa lead okuva omwaka guno. Okulowooza ku nti ekika kya bbaatule za echelon si kumpi kimala kutuukiriza, mazima ddala wajja kubaawo ebbidde ly’obwetaavu bw’okugula n’okukyusa bbaatule za lithium nga mu mwaka gwa 2020. Ekirala, base stations empya ddala 50,000-100,000 mazima ddala zijja kukolebwa buli mwaka, ezijja okufulumya 1.2-2.4 GWh ez’obwetaavu bwa bbaatule za lithium. Okutwaliza awamu, wajja kuba n’akakwate ku 10GWh ez’obwetaavu bwa bbaatule buli mwaka, nga kino mazima ddala kijja kutuukibwako bbaatule za iron-lithium-ion awamu ne bbaatule ezikozesebwa mu cascade.

Recap: Lithium-ion battery power storage tekinologiya ow’omulembe alina ebirungi eby’obulungi obw’amaanyi, okukozesa okukyusakyusa, era n’omutindo gw’okukola amangu, awamu n’okugenda mu maaso n’okubeera mu mbeera enkulu egenda mu maaso mu katale k’ekifo ky’okutereka amaanyi. Battery za lithium-ion zisobola okukozesebwa mu maanyi ag’omutindo ogwa waggulu, okufuga obwesigwa, amaanyi ag’okutereka, okusenya ku ntikko, okuddukanya amaanyi, ekifo we batereka amaanyi agazzibwawo, n’ebirala.
