Omutindo gw’ebyekikugu n’enkola z’akatale ez’okugatta V2G bikyagenda mu maaso n’okukulaakulana. Okussa mu nkola obulungi kyetaagisa ebyuma ebisasula ebikwatagana, enkola z’empuliziganya ezikozesebwa, n’ensengeka ezisikiriza bakasitoma eziliyirira bannannyini mmotoka olw’okuvunda kwa bbaatule n’okugaba empeereza.
Enkola z’okuteebereza ez’omulembe
Obugezi obukozesebwa n’okuyiga kw’ebyuma byeyongera okulongoosa enkola y’okutereka bbaatule z’amasannyalaze agazzibwawo. Enkola zino zikola ku datasets ennene omuli enkola y’obudde, omulembe gw’ebyafaayo, embeera y’omukutu, n’emiwendo gy’akatale okulagula enteekateeka ezisinga obulungi ez’okusasula-okufulumya.
Obutuufu bw’okuteebereza bukosa butereevu obusobozi bw’enyingiza. Ne bwe wabaawo okulongoosa okutono mu kuteebereza emiwendo gy’amasannyalaze agazzibwawo oba amasannyalaze kivvuunulwa mu magoba ag’amakulu mu by’enfuna mu bifo ebinene eby’okutereka. Okunoonyereza kussa essira ku nkola z’okuteebereza mu kibiina (ensemble forecasting methods) ezigatta ebikozesebwa ebingi eby’okuteebereza okusobola okufuna obutuufu obw’ekika ekya waggulu.
Ebibuuzo Ebitera Okubuuzibwa
Kiki ekitera okuteekebwako bbaatule okutereka amaanyi agazzibwawo?
Pulojekiti ez’omutindo gw’ebikozesebwa-zeetaaga emyezi 18-36 okuva ku nteekateeka esooka okuyita mu nkola y’ebyobusuubuzi, omuli okuwa olukusa, okunoonyereza ku kuyungibwa, okugula, okuzimba, n’okutandika okukola. Ebifo eby’obusuubuzi bitera okuggwa mu myezi 6-12, ate enkola z’amayumba zisobola okukola mu nnaku okutuuka ku wiiki okusinziira ku byetaago by’olukusa. Enkola y’okuyunga etera okukiikirira ekitundu ky’ebiseera ekisinga obuwanvu ku nkola eziyungiddwa ku mudumu.
Enkola z’okutereka bbaatule ezigatta ziwangaala bbanga ki?
Enkola z’omulembe ez’okutereka bbaatule z’amasoboza agazzibwawo aga lithium-ion zikakasibwa okumala emyaka 10-15 oba enzirukanya 4,000-8,000, ekisookera ddala. Obulamu obutuufu businziira ku mbeera y’emirimu, obuziba bw’okufulumya, okuddukanya ebbugumu, n’emirundi gy’enzirukanya. Enkola eziddukanyizibwa obulungi zisobola okukola emyaka 20+ nga zirina okwongeza obusobozi buli luvannyuma lwa kiseera okusobola okumalawo okuvunda mpolampola. Enkola etera okukendeera okutuuka ku 70-80% ku busobozi obw’olubereberye ku nkomerero y’obulamu obugereddwa.
Ebikozesebwa ebiriwo ebizzibwa obuggya bisobola okwongera okutereka bbaatule nga bidda emabega?
Ebifo ebisinga eby’amasannyalaze g’enjuba n’empewo bisobola okugatta okutereka bbaatule oluvannyuma lw’okuzimba mu kusooka, wadde ng’enkola y’ebyenfuna n’eby’ekikugu ya njawulo. AC-coupled solutions ziwa retrofits ennyangu okuva lwe ziyunga wansi wa inverters eziriwo. Pulojekiti zirina okukakasa ebikozesebwa ebimala eby’amasannyalaze, ekifo ekirabika, n’obusobozi bw’okuyunga okusobola okusikiriza okutereka okwongezeddwa. Ebimu ku bikozesebwa eby’edda biyinza okwetaagisa okulongoosa inverter okusobozesa okugatta bbaatule.
Enkola za bbaatule ezigatta (integrated battery systems) zeetaaga ndabirira ki?
Enkola za lithium-ion zeetaaga okuddaabiriza okutono ennyo buli kiseera - okusinga okulongoosa pulogulaamu, okwekebejja inverter, n’okukebera enkola y’okuddukanya ebbugumu. Module za bbaatule zennyini zitera okukola nga teziddaabiriza-mu biseera bya ggaranti. Okukebera buli mwaka kukakasa ebiyungo, okulondoola emitendera gy’okuvunda, n’okukakasa nti enkola z’obukuumi zikola bulungi. Embalirira 1-2% ku nsaasaanya y’enkola buli mwaka ku mirimu n’okuddaabiriza, nga okukyusa ebitundu ebikulu kiyinza okwetaagisa oluvannyuma lw’emyaka 10-15.
Ebikulu ebirina okulowoozebwako okusobola okutuuka ku buwanguzi mu kwegatta
Ensonga eziwerako ze zisalawo oba okugatta okutereka bbaatule z’amasannyalaze agazzibwawo kuwa emigaso egisuubirwa.
Ebintu bya pulojekiti-eby'ekifo ebitongole bikwata nnyo ku nteekateeka y'enkola. Ebikozesebwa mu by’amasannyalaze ebiriwo, obuzibu bw’ekifo ekirabika, ebbugumu erisangibwa mu kifo, n’obusobozi bw’okuyungibwa byonna bikwata ku kulonda tekinologiya n’okulonda okusengeka. Okukebera ekifo mu bujjuvu mu kiseera ky’okuteekateeka kiziyiza enkyukakyuka ezitwala ssente nnyingi mu kiseera ky’okuzimba.
Enkola z‟okwetaba mu katale zirina okukwatagana n‟obusobozi bwa bbaatule n‟emikisa gy‟omu kitundu. Ebitundu ebirina emiwendo gy’amasannyalaze egy’enjawulo byagala nnyo enkola z’okutereeza amasannyalaze, ate ebitundu ebirina emiwendo gy’amasannyalaze egy’amaanyi biwa obutuufu bw’enkola z’okugerageranya obunene okusobola okutuukiriza ebiseera eby’obwetaavu obw’oku ntikko. Pulojekiti eziwangudde zitera okutuuma emikutu gy’ensimbi egy’enjawulo omuli amaanyi, obusobozi, n’obuweereza obuyambi.
Obukugu mu mirimu bulaga nti kyetaagisa okusobola okutumbula omulimu. Abaddukanya emirimu egy’obukugu abategeera tekinologiya wa bbaatule n’obutale bw’amasannyalaze bulijjo baggya omuwendo omungi okuva mu by’obugagga ebitereka bbaatule z’amasannyalaze agazzibwawo. Obukugu buno buzingiramu okusalawo ku kusindika mu kiseera ekituufu-, okuddukanya okusaanyizibwawo, enkola z’okutunda akatale, n’enteekateeka y’okuziyiza okuddaabiriza.
Ensengeka y’ebyensimbi ekosa nnyo obusobozi bwa pulojekiti nga bwe kiri ku nteekateeka y’eby’ekikugu. Okukendeeza ku musolo gw’okusiga ensimbi, okukendeeza ku muwendo mu bwangu, n’okusikiriza gavumenti bisobola okukendeeza ku nsaasaanya ya kapito ebitundu 30-50%. Endagaano z’okugula amasannyalaze, endagaano z’obusobozi, n’enkola endala ez’okukakasa enyingiza bifuula pulojekiti okuweebwa ensimbi nga zikendeeza ku bulabe. Abakola emirimu beeyongera okukozesa enkola ey’omulembe mu by’ensimbi okusobola okulongoosa amagoba ga pulojekiti.
Enkyukakyuka y’amasoboza agazzibwawo yeetaaga okuteekebwa mu nkola y’okutereka amaanyi amangi okusobola okuddukanya obutasalako n’okukakasa nti omukutu gw’amasannyalaze gwesigika. Tekinologiya wa bbaatule akuze okutuuka ng’okugatta n’amasannyalaze g’enjuba n’empewo kufuuse enkola ey’omutindo okusinga okugiteeka mu nkola mu kugezesa. Okukendeera kw’ebisale, okuwagira enkola, n’obumanyirivu mu mirimu byanguya okutwalibwa mu bitundu by’akatale byonna.
Ebiziyiza eby’ekikugu mu kugatta okutereka bbaatule z’amasannyalaze agazzibwawo okusinga bigonjoddwa nga bayita mu nkola ezikakasibwa ez’okugonjoola ebizibu bya Hardware ne software. Okusoomoozebwa okusigaddewo kwesigamye ku nkola z’amateeka, enkola z’okuyunga, n’okulongoosa enkola ya bizinensi okusinga okukoma ku tekinologiya ow’omusingi. Nga ebizibu bino ebitali-eby’ekikugu bikendeera, okutereka kujja kweyongera okusobozesa okukola amasannyalaze agazzibwawo okusobola okuwa amasannyalaze agesigika, agasindikibwa emikutu gy’omulembe gye geetaaga.
