Impamvu PV + BESS ari yo ihuza neza cyane

Gutanga imirasire y'izuba n'amashanyarazi bikenera amashanyarazi mu buryo busanzwe ntibihuje neza. Izuba rigera ku manywa y'ihangu, ariko gusharija ku manywa y'ihangu bigera ku manywa y'ihangu mu gihe cyo kujya mu kazi no mu gihe cyo kuva saa sita kugeza nimugoroba. Ahantu hagenewe PV gusa hahura n'amahitamo mabi: kohereza hanze amafaranga y'inyongera ku giciro cyo kugurisha, cyangwa kuyagabanya burundu. BESS ikuraho amahitamo—bateri ifata amafaranga y'inyongera ikayarekura neza neza igihe chargers ziyikeneye.

Inyungu mu mikorere myiza ifite ibice bitatu:

1. Inyungu mu gukoresha: buri kilowati y'izuba ikoreshwa ku giciro cya bucuruzi cyangwa ku giciro cya tarifu aho koherezwa mu mahanga ku giciro cya bucuruzi cyangwa gukatwa. Ibi ubusanzwe bifite agaciro ka 30–50% by'amafaranga yinjira kuri kWh imwe yinjizwa. 2.Inyungu ku guhindura ubukungu: mu buryo bwa DC-coupled, DC y'izuba inyura muri DC bus ya bateri cyangwa DC bus ya charger, birinda ko AC ijya no kugaruka. Gukuraho conversion ebyiri za inverter bigarura amanota 2-4 ku ijana y'imikorere myiza ya sisitemu. 3.Inyungu ku busabe bw'umuyoboro w'amashanyarazi: urubuga rutumiza bike mu ikoranabuhanga, naho ibindi bicuruzwa biva mu mahanga ni bike, bigabanya amafaranga y’ingufu n’ay’ibikenewe.

Ku mukoresha ugereranya ihuriro rya PV + BESS n'aho amashanyarazi yihuta gusa, ikiguzi cy'ingufu zitangwa muri sisitemu ihujwe akenshi kiba kiri hasi ho 20–35% mu myaka icumi ishize.

Ingufu zigenda: Kuva kuri Panel kugeza kuri Bateri kugeza kuri Mota

Gusobanukirwa imiterere y'imikoranire bisobanura neza aho ubushobozi bugerwaho cyangwa butakaye. Hari imiterere ibiri isanzwe:

Guhuza AC— Inverters za PV zitanga umuriro kuri AC bus; inverter ya batiri yihariye niyo ikoresha batiri. Ingufu zoroheje kandi zisanzwe, ariko zikomoka ku mirasire y'izuba zitakaza PV-inverter, hanyuma batiri-inverter itakaza: ubushobozi bwo gusubira inyuma bwa 85–88%.

Guhuza DC— Imiterere ya PV ihuza na bisi ya DC ya batiri binyuze muri MPPT converter; PCS imwe yo hagati icunga ihererekanya ry’amashanyarazi. Ingufu z’izuba zinjira muri batiri hamwe n’ihererekanya rimwe, kandi imikorere myiza yo gusubira no kugaruka irushaho kuba myiza kugeza kuri 90–93%. Iyo chargers zishobora gukura DC muri bisi ihuriweho, irindi hererekanya riravanwaho.

Igishushanyo mbonera cya DC-coupled ni cyo gituma ibikoresho bya BESS bihujwe n’ingufu z’izuba biri gutsinda ibikorwa byo mu bucuruzi. Itandukaniro mu mikorere riboneka buri munsi: ku musaruro wa MWh 1 ku munsi, amanota 3-5 ku ijana by’ingufu zikomoka ku mirasire y’izuba zibitswe ni 30-50 kWh ku munsi—hafi MWh 11-18 ku mwaka z’ingufu zishobora kugaruzwa.

Sitasiyo igezweho [200 kWh solar BESS EV charger Station-for-zero-emission-sites/] (https://www.midapower.com/news/200kwh-solar-bess-ev-charging-station-for-zero-emission-sites/) igaragaza uruhererekane rwuzuye: PV array → MPPT module → bateri DC bus → DC fast charger → bateri y'imodoka. Buri cyiciro cyagenewe igihombo gito, kandi EMS ihuza urujya n'uruza rw'amazi ku buryo imirasire y'izuba ihora itanga umutwaro mbere ya byose, amafaranga y'inyongera kuri BESS, kandi ibicuruzwa byinjizwa mu ikoranabuhanga bigabanywa.

Ingano y'imirongo y'izuba ugereranije n'ubushobozi bwa BESS

Amakosa mu gupima ingano—PV nini cyane cyangwa ububiko bunini cyane—yangiza bucece ubukungu bw'imikorere y'ikoranabuhanga. Igipimo cy'ingenzi ni umusaruro w'izuba buri munsi ugereranyije n'umusaruro wa batiri n'ikiguzi cy'aho ikoreshwa:

Amategeko atatu agenga ingano atuma guhuza neza:
