Kunanirwa kwa gride kugaragara nkinshuro cyangwa gutandukana kurenza imipaka yumutekano, birashobora guteza ibikoresho kwangirika no guhagarara. Sisitemu zo gukingira zihita zihagarika uduce twibasiwe kugirango twirinde kwangirika kwinshi, bivamo umwijima. Kugarura birashobora gufata amasaha cyangwa iminsi bitewe nuburemere bwatsinzwe, nkuko ababikora bagomba kwitonda re- guha ingufu ibice mugihe bakomeza umutekano. Umwijima wo mu majyaruguru y'uburasirazuba wa 2003 werekanye uburyo ihungabana ry'umuriro - kunanirwa kw'umurongo w'amashanyarazi byakwirakwijwe binyuze mu igenzura ridahagije, amaherezo bikaba byibasiye miliyoni 50 mu bihugu umunani byo muri Amerika na Kanada.
Imashanyarazi ishobora kuvugururwa irashobora kugera ku gihagararo kimwe na peteroli ya fosile?
Nibyo, amashanyarazi ashobora kuvugururwa arashobora guhuza cyangwa kurenga imyanda ya peteroli ihindagurika mugihe ifite tekinoroji ikwiye. Ububiko bwa bateri, sisitemu yubukorikori, hamwe nubuyobozi buhanitse butanga serivise zihamye zitangwa na moteri izunguruka. Californiya yerekanye ubwo bushobozi mu 2024, ikoresha ingufu zisukuye 100% muminsi 60% mugihe ikomeza kwizerwa. Urufunguzo rurimo gukoresha ibikorwa remezo bihagije - bateri, gride - ikora inverter, hamwe na sisitemu yo kugenzura - hamwe nibisekuru bishobora kuvugururwa. Ubushakashatsi bwakorewe muri Laboratwari y’igihugu y’ingufu zemeza ko ibishobora kuvugururwa bishobora gutanga serivisi zihamye "birashoboka bitandukanye n’ibiri kuri gride" mugihe byateguwe neza.
Nigute sisitemu yo kubika ingufu za batiri itezimbere imiyoboro ihamye?
Sisitemu yo kubika ingufu za bateri zongera ituze binyuze muburyo bwinshi bukora mubihe bitandukanye. Kugirango uhagarike inshuro, bateri zisubiza muri milisegonda 20 - 100 kugirango zite cyangwa zinjize ingufu, byihuse cyane kuruta moteri isanzwe isaba amasegonda 5 - 10. Kugirango imbaraga za voltage zihamye, bateri zitanga imbaraga zidasanzwe, zigumana urwego rukwiye rwa voltage murusobe. Ku micungire yingufu, bateri zibika ibisekuru byinshi bishobora kuvugururwa mugihe gito - mugihe cyibisabwa no gusohora mugihe cyo hejuru, koroshya ubusumbane bwibisabwa. Ikigega cy’amashanyarazi cya Hornsdale muri Ositaraliya cyerekanye ubwo bushobozi, gihindura umurongo wa gride muri milisegonda 140 mugihe uruganda rwamakara rwananiwe gukumira umwijima ushobora kwibasira abakiriya ibihumbi.
Kuki kugabanya inertia bifite akamaro kuri grid stabilite?
Inertia yerekana imbaraga zo kuzunguruka zibitswe mumashanyarazi azunguruka ihita irwanya impinduka zinshyi. Iyo generator igenda kumurongo, inertia itinda kugabanuka kwinshuro, itanga igihe cyo kugenzura sisitemu yo gukora ububiko. Hasi - inertia gride ifite uburambe bwihuta bwihuta - birashoboka kugabanuka kuva kuri Hz 60 kugeza kuri 59.5 Hz mumasegonda imwe aho kuba amasegonda 5 - 10. Ihinduka ryihuse ryibibazo birinda ibikoresho byo kurinda hamwe na sisitemu zo kugenzura zagenewe gusubiza buhoro. Ubushakashatsi bwerekana gusimbuza 40% byigihe kimwe nibishobora kuvugururwa birashobora kugabanya inertia 60%, bikikuba inshuro eshatu umuvuduko wimpinduka zumuvuduko mugihe cy'imivurungano. Sisitemu ya inertia ya sintetike igabanya iki kibazo mukoresheje uburyo bwa elegitoronike kwigana inshuro-ituje yimyitwarire yumubiri.
Inzira Imbere
Imiyoboro ihamye yerekana imwe mu mbogamizi zikomeye za tekiniki muguhindura ingufu kwisi. Kuzigama neza imbaraga zizewe mugihe uhindukiye kumasoko ashobora kuvugururwa bisaba imbaraga zihuriweho mugutezimbere ikoranabuhanga, igishushanyo mbonera cyamasoko, hamwe nuburyo bwo kugenzura.
Ibisubizo bya tekiniki birahari kandi bikomeze gutera imbere. Batteri, inertia yubukorikori, gride - ikora inverter, hamwe nubugenzuzi buhanitse bitanga serivisi zihamye zingana cyangwa nziza kuruta inzira gakondo. Ibiciro biragabanuka nkuko umunzani woherejwe - ibiciro bya batiri byagabanutse 90% mumyaka icumi ishize, bihindura ubuzima bwubukungu.
Imiterere yisoko igomba guhinduka kugirango ihe agaciro neza serivisi zihamye. Ingufu gakondo - gusa amasoko yishyura bidahagije umutungo wo gutanga amabwiriza yumurongo, inkunga ya voltage, hamwe nubusembure. Californiya, Texas, na Ositaraliya byateje imbere ibicuruzwa bishya byisoko byishyura byimazeyo imisanzu ihamye, ishishikarizwa kohereza ikoranabuhanga rikwiye.
Ibikorwa bigenga bisaba kuvugurura kugirango habeho paradigms nshya. Imiyoboro ya gride yanditswe kuri generator ikora ikenera gusubiramo kugirango igaragaze imikorere ikenewe muri inverter - ibikoresho. Uburyo bwo guhuza ibikorwa bugomba gusuzuma imbaraga za sisitemu ningaruka zihamye, ntabwo ubushobozi bwibisekuruza gusa.
Ihinduka risaba ishoramari rinini ariko ritanga inyungu zikomeye zirenze umutekano. Kugabanya ibicanwa bya fosile bigabanya ibyuka bihumanya ikirere, bikemura ibibazo by’imihindagurikire y’ikirere. Ububiko bunoze kandi bworoshye butuma byinjira cyane byinjira, byihutisha decarbonisation. Gukurikirana no kugenzura byongerewe imbaraga za gride zifite imbaraga zo guhangana nikirere gikabije.
Imiyoboro ihamye mugihe gishobora kuvugururwa itandukanye cyane nuburyo gakondo, ariko iracyagerwaho binyuze mugutegura neza, ishoramari, no gukoresha ikoranabuhanga. Ibimenyetso byaturutse mu turere twayoboye byerekana ko ingufu zisukuye nimbaraga zizewe zitavuguruza intego - ni intego zuzuzanya zisaba kwishyira hamwe.
