Yini i-microgid?

I-Yulumi inikeza isixazululo esiphelele se-microgid. Imikhiqizo yethu eyisisekelo ifaka amabhethri wokugcina amandla, ama-inverters, akwenza kube lula ukwakha i-microgid.to ehlinzeka ngogesi enobungane bemvelo ukuphendula amanani entengo kagesi ekhuphukayo.

Microgrid solution

Abantu abaningi ngokwengeziwe bakhathazeka ngokubuyiselwa nokuthembela emandleni. Lapho kunokuphuma ngaphandle, kuhlelwe noma kungakahlelwanga, futhi igridi iya emnyama; Yini esingayenza? Isixazululo sale nkinga singama-microgids, ngokubambisana namandla avuselelekayo anjengamandla elanga.

Yini i-microgid?

I-microgrid iyigridi yamandla endawo enekhono lokulawula, okusho ukuthi inganqamula kusuka kugridi yendabuko futhi isebenze ngokuzimele. 1 Ngokusho koMnyango Wezamandla E-US Energy Miccid Exchange, Inqubo elandelayo ichaza i-microgid:

I-microgrid yiqembu lemithwalo exhumekile futhi isatshalaliswe izinsiza zamandla ngaphakathi kwemingcele kagesi echazwe ngokucacile esebenza njengenhlangano eyodwa etholakalayo maqondana negridi. I-microgrid ingaxhuma futhi ikhiphe ngqo kugridi ukuze ikwazi ukusebenza kuyo yomibili elixhunywe ngegridi noma i-Island-Mode. 2

Ukuhlangabezana nezidingo zikagesi zabasebenzisi bayo, i-microgid kumele ibe nomthombo wesizukulwane. Njengoba kunikezwe ukuthi ama-migrigrids angumqondo omdala, ugesi onikezwe ama-microgids avela "ngemuva kwamamitha" ama-fossil Fuel generator - ama-generator aphethwe yigesi, ngokwesibonelo. Kodwa-ke, ngezindleko eziwayo ze-solar, ungasaphathwanga izinzuzo zemvelo zokushintsha kusuka ekuphethweni kwamafutha elanga kuya emandleni elanga, ama-microgrids aklanywe nanamuhla ukuhlinzeka ngogesi ngenhlanganisela ye-solar kanye ne-solar plattery. +

Izinzuzo zama-Micrographs

Kunezinzuzo ezingaphezu kwezinzuzo eziningana zama-Micrograds: 4

  • Nikeza amandla asebenzayo, aphansi, amandla ahlanzekile
  • Thuthukisa ukusebenza nokuqina kwegridi kagesi yesifunda
  • Ingqalasizinda Ebucayi Eyandisa Ukwethembeka Nokuqina
  • Yehlisa ukugcwala kwegridi kanye nemithwalo ephakeme
  • Nika amandla i-CHP esebenza kahle kakhulu, ukunciphisa ukusetshenziswa kwamafutha, ukulahleka komugqa, kanye ne-carbon footprint
  • Hlanganisa i-CHP, ukuvuselelwa, okushisayo kanye nokugcinwa kukagesi, kanye nohlelo oluthuthukile kanye nezilawuli zokwakha
  • Yenza amamakethe we-RTO ancintisana kakhudlwana
  • Nikeza izinsizakalo zegridi kubandakanya namandla, umthamo, kanye nezinsizakalo ezihambisanayo
  • Izindawo zokusekela zokuphephela ezigabeni zesifunda kanye nabaphenduli bokuqala
  • Sebenzisa izinsizakusebenza zamandla endawo nemisebenzi
  • Ubungozi obuhlukahlukene kunokuba ubungozi obuhlanganisiwe
  • Usebenzisa amakhono okugcina kagesi nawama-armal, i-microgrid kunganikeza ukuphathwa kwasendaweni kwesizukulwane esiguqukayo, ikakhulukazi elanga ephakathi esizeni
  • Lapho yakhelwe kahle, igridi yamandla yesifunda ehlanganisa izitshalo ezinkulu eziphakathi nendawo futhi isatshalaliswe ama-microgrids angakhiwa ngezindleko ezinkulu zemali, isizukulwane esincane esifakiwe, nokuthembeka okuphezulu kuwo wonke amafa, kanye nokwethenjwa okuphezulu.

Kusetshenziswa kanjani ama-microgrids

Igridi ixhuma amakhaya, amabhizinisi, nezinye izakhiwo emithonjeni yamandla aphakathi, esivumela ukuthi sisebenzise izinto, ukufudumeza / ukupholisa izinhlelo, kanye ne-elekthronikhi. Kepha lokhu kuxhunyaniswa kusho ukuthi lapho ingxenye yegridi idinga ukulungiswa, wonke umuntu uyathinteka.

Yilapho i-microgid ingasiza khona. I-microgrid isebenza ngokuvamile ngenkathi ixhumeke kugridi, kodwa ngokubalulekile, ingahlukana futhi isebenze ngokwayo kusetshenziswa amandla endawo ezikhathini ezinjengeziphepho noma ngezinye izizathu.

I-microgid inganikwa amandla ngabakhiqizi abasatshalaliswa, amabhethri, kanye / noma izinsiza ezivuselelekayo njengamaphaneli elanga. Kuya ngokuthi kubhekwe kanjani nokuthi izimfuneko zawo zilawulwa kanjani, ingahle isebenze nge-microgid unomphela.

I-microgid ayigcini nje ngokusekela nge-grid uma kwenzeka izimo eziphuthumayo, kepha futhi ingasetshenziswa ukusika izindleko noma ukuxhuma kwisisetshenziswa sendawo esincane kakhulu noma esingathembekile ekusetshenzisweni kwegridi yendabuko.

I-microgrid ivumela imiphakathi ukuba isebenze ngamandla amaningi futhi, kwezinye izikhathi, inobungane obuningi. 1

AmaMicrogrid akwazi ukuhlukaniswa ngogesi kusuka ku-grid uma kwenzeka kwenzeka ukuphuma. Lapho igridi yehla ngenxa yanoma yini evela emcimbini wesimo sezulu esibi esigxotsheni esigxotshelwe ngaphezulu kwezingcingo, udinga ukunqanyulwa kugridi-noma "i-Islandwed" -in ukuze uqhubeke nokukhiqiza nokusebenzisa ugesi. Kanjalo, isici esingukhiye esisodwa se-microgid yikhono laso sokuqhubeka nokusebenza noma ngabe igridi enkulu iphuma. +

Ezimweni ezinjengemililo evuthayo eCalifornia muva nje, ama-Microgids azoba yinzuzo. Amaphepheni amaningi eCalifornia aphelelwa yi-california ukuze ama-Powerlines awashayiswa phansi futhi ahlele imililo eminingi. Kubantu abaningi, i-microgid kungaba yisixazululo senkinga yawo yamandla ngokukwazi ukukhiqiza amandla abo ngamaphaneli elanga nokugcina la mandla okusetshenziswa eziphuthumayo. Le mindeni inganqamula kusuka kugridi enkulu futhi yanele kuze kube yilapho igridi enkulu ibuyile ku-inthanethi.

Uma unesitoreji samandla noma enye iphrojekthi yamandla ofuna ukubhangqa nge-microgid, usinikeze chofoza ku Xhumana nathi inkinobho.
