Kuvandudza Kushanda Nesimba kuburikidza neBESS neSolar Power Coupling

Mhinduro Inokurumidza

Kubatanidza simba remagetsi emabhatiri (BESS) nesimba rezuva panzvimbo yacho ndiyo nzira inoshanda zvakanyanya yekuchaja nzvimbo yemazuva ano yeEV nekuti inorwisa kurasikirwa padanho rega rega remagetsi. Mapaneru ezuva anoshandura chiedza chezuva kuita DC pakushanda zvakanaka kwemodule ye20–24%; sisitimu yekutevera mapoinzi emagetsi (MPPT) inodzoreredza zvaigona kutambisa mumvuri nekusawirirana; uye bhatiri rinobvisa kugadzirwa kwemagetsi kubva pakudiwa kwekuchaja kuitira kuti pasave nekilowatt-awa inotengeswa kunze kwenyika nemitengo yakawanda kana kuderedzwa. Sisitimu yePV+BESS yakabatana zvakanaka inowanzo simudza kukosha kwekugadzirwa kwemagetsi ezuva ne30–50% zvichienzaniswa nePV-chete, inoderedza kutenga kwemagetsi egrid ne40–70%, uye inobvumira kushanda kwe zero-emission panguva yemasikati. Gwaro iri rinotsanangura maitiro ekugadzira saizi, kubatanidza, uye kushandisa solar nekuchengetedza kuti zvibudirire zvakanyanya parwendo rwekudzoka nekudzoka.

Zvinhu Zvinokosha Zvaunofanira Kuziva

• Kubatana kweDC kwePV neBESS kunodzivirira kurasikirwa kwekuchinja kaviri, zvichivandudza kushanda zvakanaka kwesystem ne2–4 muzana.
• Bhatiri rinotora simba remagetsi rinoshandisa simba rezuva uye rinorichinja kuti rive nesimba rekuchaja, zvichibvisa kuderedzwa kwesimba remagetsi uye kutengeswa kwemagetsi kunze kwenyika kusingakoshi zvakanyanya.
• Mamodule eMPPT ane ma voltage akafara anodzoreredza 5–10% ye PV output yakarasika nekuda kwe partial shading uye kusawirirana kwema panel.
• Saizi chaiyo yezuva kubva pabhatiri inoita kuti nzvimbo yekuchengetera zvinhu irambe ichienderera mberi ka1-1.5 pazuva, zvichidzivirira hupenyu hwenguva yacho uye mari inoshandiswa.
• Nzvimbo dzeBESS dzinoshandisa simba rezuva dzinogona kushanda senzvimbo dzisina kuburitsa mweya, dzichibvisa majenareta edhiziri panzvimbo dziri kure uye dzine grid shoma.

Nei PV + BESS iriyo nzira yakanakisisa yekubatanidza zvinhu

Kugadzirwa kwezuva uye kudiwa kwekuchaja kwemagetsi emagetsi zvinokanganiswa. Zuva rinosvika pakakwirira masikati, asi kudiwa kwekuchaja kunosvika pakukwirira mangwanani uye kubva masikati kusvika manheru. Nzvimbo yePV chete inosangana nesarudzo isingafadzi: kutumira kunze yakawandisa masikati nemitengo yakawanda, kana kuideredza zvachose. BESS inobvisa sarudzo—bhatiri rinotora yakawandisa uye rinoiburitsa panguva chaiyo iyo machaja aiida.

Kubudirira kwekushanda kune zvikamu zvitatu:

1. Kuwanikwa kwekushandisa: makilowatt-awa yega yega yezuva inodyiwa panzvimbo yacho pamutengo wekutengesa kana wemutero pachinzvimbo chekutengeswa kunze kwenyika pamutengo wekutengesa kana kuchekwa. Izvi zvinowanzo bhadhara mari yakawanda ne30–50% pa kWh inogadzirwa. 2.Kuwana kwekuchinja: muchimiro chakabatana neDC, solar DC inoyerera zvakananga mubhazi reDC rebhatiri kana mubhazi reDC recharger, zvichidzivirira AC kuenda nekudzoka. Kubvisa ma inverter maviri anochinja kunoita kuti system ishande zvakanaka ne2-4 muzana. 3.Kudiwa kwegrid kunowedzera: nzvimbo yacho inotenga zvinhu zvishoma kubva pagrid, uye zvimwe zvinotengeswa kunze kwenyika hazvina kunyanya kudhura, zvichideredza mari yemagetsi nemari yekuda.

Kune mushandisi anoenzanisa hub yePV+BESS nenzvimbo yekuchaja nekukurumidza yegrid chete, mutengo wesimba rinounzwa wesystem iyi unowanzo kudzikira ne20–35% mumakore gumi anotevera.

Kufamba Kwesimba: Kubva Papaneru Kuenda Kubhatiri Kuenda Kumotokari

Kunzwisisa magadzirirwo ekubatanidza kunojekesa kuti kushanda zvakanaka kunowanikwepi kana kuti kunorasika kupi. Kune ma topology maviri makuru:

Kubatanidza kweAC— Ma-inverter ePV anodyisa bhazi reAC; bhatiri rakasiyana rinodyisa bhatiri. Simba rezuva riri nyore uye rinochinja-chinja, asi rinorasikirwa nePV-inverter, uye bhatiri-inverter rinorasikirwa: kushanda zvakanaka kwe85–88%.

DC coupling— MaPV arrays anobatanidza nebhazi reDC rebhatiri kuburikidza nechinoshandura MPPT; imwe PCS yepakati inobata kuchinjana kwegrid. Simba rezuva rinopinda mubhatiri nekutendeuka kamwe chete, uye kushanda zvakanaka kwekudzoka kunovandudzika kusvika pa90–93%. Kana machaja achigona kudhonza DC zvakananga kubva mubhazi rakagovaniswa, kumwe kuchinja kunobviswa.

Dhizaini yakabatana neDC ndiyo inoita kuti zvigadzirwa zve solar-BESS zvakabatana zvibudirire. Musiyano wekushanda unowanikwa zuva nezuva: pa 1 MWh zuva nezuva, 3-5 muzana yekurasikirwa kwekuchinja kwakachengetwa i30-50 kWh pazuva—inenge 11-18 MWh pagore yesimba rinodzoserwa.

Nzvimbo yekuchaja yemazuva ano ye [200 kWh solar BESS EV charging station] (https://www.midapower.com/news/200kwh-solar-bess-ev-charging-station-for-zero-emission-sites/) inoratidza chain yakazara: PV array → MPPT module → battery DC bus → DC fast charger → vehicle battery. Danho rega rega rakagadzirwa kuti rideredze kurasikirwa, uye EMS inobatanidza kuyerera kuitira kuti solar igare ichipa mutoro kutanga, mari yekuwedzera inopihwa BESS, uye grid imports inoderedzwa.

Kukura kweSolar Arrays Zvichienderana neBESS Capacity

Zvikanganiso pahukuru hwema "saizi"—PV yakakura kana nzvimbo yekuchengetera zvinhu yakakura—zvinoparadza chinyararire hupfumi hwema "coupled systems". Chiyero chinotonga i "solar good" yezuva nezuva zvichienzaniswa ne "battery throughput" uye kudiwa kwenzvimbo:

Mitemo mitatu yehukuru inoita kuti kubatana kushande zvakanaka:

1. Saizi yePV kusvika 40–80% yesimba repagore renzvimbo, kwete 100%. Kufukidza kwakazara kunomanikidza bhatiri kukura zvakanyanya uye nguva refu yekusashanda; kufukidza zvishoma kunowedzera kukosha kwezuva pa watt imwe neimwe yakaiswa. 2.Saizi yeBESS kusvika padanho rimwe chete pazuvabhatiri rinotenderera kamwe chete pazuva pahudzamu hwe80% hwekubuda kwesimba rinoita kuti rive rakakwana; mabhatiri madiki anotenderera zvakanyanya, uye mabhatiri makuru anoparadza hupenyu hwekarenda pasina kushandiswa. 3.Enzanisa huwandu hweMPPT input nehwindo rekushanda re array.Module yeMPPT ine simba guru inodzoreredza simba pasi pemumvuri wechikamu, mhute yemangwanani, uye kuchembera kwepaneru uko unit ine daro rakamanikana inobvisa.

Kubudirira Kunobudirira: MPPT, Kutendeuka, uye Kurasikirwa Kwenguva Yakamira

Kushanda zvakanaka kunowanwa muzvinhu zvakadzama, uye mapoka matatu ekurasikirwa anotonga masisitimu akabatana:
