Isistimu ye-microgrid kanye nesistimu yokukhiqiza amandla e-off-grid photovoltaic yizakhiwo ezimbili ezihlukene zenethiwekhi ezinezici zazo ezihlukile kanye nezinhlelo zokusebenza.

Isistimu yegridi encane ingumqondo wokuphakelwa kukagesi ohlukile ohlelweni lwegridi yamandla amakhulu. Inethiwekhi eyakhiwe amasistimu okugcina amandla asabalalisiwe amaningi kanye nemithwalo yawo ehlobene, exhunywe kugridi yamandla evamile ngokusebenzisa amaswishi. Lolu hlelo luyakwazi ukuzithiba, ukuvikela, nokuphatha, lusebenza kokubili ngokuhlangana negridi yamandla yangaphandle noma ngokuhlukaniswa. Imishini eyinhloko ohlelweni lwe-microgrid ihlanganisa ukusabalalisa amandla kagesi kanye nezinhlelo zokugcina amandla, njengama-inverter axhunywe kugridi ye-photovoltaic, ama-inverter axhunywe kugridi yamandla omoya, izinjini zikadizili, i-PCS, ne-BMS. Lolu hlelo luyinkimbinkimbi kakhulu futhi ludinga imithombo yamandla esabalaliswe kakhulu uma iqhathaniswa namanye amasistimu okugcina amandla Asabalalisiwe.

Ngakolunye uhlangothi, isistimu yokukhiqiza amandla e-photovoltaic engaphandle kwegridi, eyaziwa nangokuthi isistimu yokukhiqiza amandla e-photovoltaic ezimele, yakhiwe ikakhulukazi izingxenye ze-PV, isilawuli sokushaja se-DC/AC, inverter engaphandle kwegridi, kanye nomthwalo. Inikeza ukunikezwa kwamandla okuzimele kanye nemisebenzi yokulondoloza amandla ezimele. Lolu hlelo lusetshenziswa kakhulu ezindaweni ezikude namagridi amakhulu kagesi, njengezingwadule, amabhishi neziqhingi. I-inverter ye-off-grid kulolu hlelo ingasebenza kuphela kusimo se-inverter futhi ayikwazi ukuxhunywa kugridi yamandla amakhulu. Idinga ukulungiswa njalo, ikakhulukazi ibhethri.

Nakuba womabili amasistimu okuphakelwa kwamandla enezici ezizimele zokunikezwa kwamandla futhi adinga amasistimu okugcina amandla, kunomehluko obalulekile phakathi kwawo. Uhlelo lwe-microgrid luwuhlelo lwe-EMS olusebenzayo, olukwazi ukuxhunywa kugridi yamandla amakhulu, kuyilapho uhlelo lokuphehla amandla e-photovoltaic ngaphandle kwegridi luwuhlelo olungenakwenziwa olungakwazi ukuxhunywa kugridi yamandla amakhulu. Isistimu ye-microgrid iyinkimbinkimbi kakhulu futhi idinga ukumiswa kwemithombo yamandla esabalaliswe kaningi, kuyilapho isistimu engaphandle kwegridi idinga kuphela isilawuli kanye nesiguquli se-off-grid. Ukwengeza, uhlelo lokugcina amandla ohlelweni lwe-microgrid luyi-inverter yokusebenza ye-quadrant ezine, okuvumela ukugeleza kwamandla okubili, kuyilapho kusistimu ye-off-grid, i-converter yesigaba esisodwa esingakwazi ukufeza izindlela ezimbili. ukugeleza kwamandla we-EMS.

Ukusetshenziswa okungokoqobo kwalezi zinhlelo kuncike ezidingweni nasezimeni ezithile. Uma uhlelo lokusebenza lusezindaweni ezikude njenge-Gobi Desert noma amabhishi, lapho kungadingeki khona ukulungiswa okuvamile, isistimu yokukhiqiza amandla e-off-grid photovoltaic ifanelekile. Lolu hlelo lungasebenza ngokuzimela ngaphandle kwesidingo sokungenelela komuntu, ngokulungiswa okuvamile kugxile ebhethrini. Kodwa-ke, uma uhlelo lokusebenza luseduze negridi enkulu yamandla futhi ludinga ukunakekelwa okuvamile okwenziwa ngesandla kanye nokuhlela okuqinile, isistimu yegridi encane ifaneleka kakhulu. Lokhu kungenxa yokuthi ukushintshwa kwemithombo yamandla ehlukene esabalalisiwe kanye nokuhlelwa kwesimo sokusebenza kudinga umsebenzi wezandla noma ngisho nokuqapha uhlelo lwe-EMS.

Sengiphetha, isistimu ye-microgrid kanye nesistimu yokukhiqiza amandla e-off-grid photovoltaic yizakhiwo ezimbili ezihlukene zenethiwekhi ezinezici ezihlukene kanye nezinhlelo zokusebenza. Isistimu yegridi encane iyinkimbinkimbi kakhulu, iyakwazi ukuxhunywa kugridi yamandla amakhulu, futhi idinga imithombo yamandla esabalalisiwe eyengeziwe. Ngakolunye uhlangothi, uhlelo lwe-off-grid lusetshenziswa kakhulu ezindaweni ezikude futhi alukwazi ukuxhunywa kugridi enkulu yamandla. Ukukhetha phakathi kwalezi zinhlelo kuncike ezidingweni nasezimweni ezithile, kucatshangelwa izici ezifana nezidingo zokunakekela kanye nokuba seduze kwegridi yamandla enkulu ye-EMS.
