Iye zvino, muIndasitiri yeSimba, nzvimbo yekuchengetera simba ndiyo inonyanya kufarirwa.
Matunhu anopfuura gumi nemaviri, anosanganisira Shandong, Shanxi, Xinjiang, Inner Mongolia, Anhui neTibet, akapa magwaro anoda kuti nzvimbo dzemagetsi dzinoshandisa simba rezuva nemhepo dzive nehurongwa hwekuchengetedza simba.
Kunyangwe indasitiri yesimba yagara ichiziva kuti "Kuchengetedza simba inzira inoshanda yekudzivirira kushaikwa kwesimba rezuva, simba remhepo uye kusagadzikana, kukurudzira kushandiswa kwesimba uye kuderedza kuderedzwa kwesimba." Kudzikiswa kwemitengo kwakadzika kunoita kuti mukana uyu uve wakakurumbira, asi nekuda kwetekinoroji yayo uye zvipingamupinyi zvemitengo zvakaita kuti "Isashande." Nhasi, sarudzo yepamutemo iri kuita kuti kuchengetedza simba kudadire.
Asi kana kuchengetedza simba kuchizopedzisa shanduko huru kubva ku "Icing on the cake" kuenda ku "Inongodiwa nemusika", hazvingodi chete rutsigiro rwakajeka uye rwakasimba rwemitemo, panguva imwe chete, tinofanira kukurudzira kuvandudzwa kweindasitiri yekuchengetedza optical kuburikidza netekinoroji uye hunyanzvi hwezvigadzirwa? Ungasanganisa Sei Zvakanaka? Ndeapi matambudziko ekubatana? Zvese izvi zvinoda kupindurwa.
1. Ndezvipi zviitiko zvehurongwa zvakajairika?
Parizvino, kune zvirongwa zvakawanda zviri kutengeswa.
Chirongwa chekubatanidza divi reAC chinoreva kuchengetwa kwemagetsi ezuva nezuva (photovoltaic) nemagetsi ari muchikamu cheAC, sisitimu yekuchengetedza simba inogona kubatanidzwa kudivi rine voltage shoma, inogonawo kubatanidzwa kubhasi re10 kV～35 kV. Chirongwa ichi chakakodzera nzvimbo huru yemagetsi yekuchengetera magetsi, kurongeka kwesystem yekuchengetedza simba pakati, Easy Operation Management uye power grid dispatching.
Chirongwa chekubatanidza simba cheDc-side chinoreva sisitimu yekuchengetedza simba yakabatana neDC side, kushandurwa kwesimba pakati pemasisitimu maviri aya, zvisungo zvishoma, kurasikirwa nesimba kushoma, uye mari shoma yekudyara mumidziyo. Muchiitiko ichi, solar inverter inofanira kuchengetedza nzvimbo yekuchengetedza simba.
2. Ungawana sei kubatanidzwa kwe1 + 1 > 2?
Kune mhinduro dzekubatanidza, asi kubatanidza kuti uwane mhedzisiro ye1 + 1 > 2, asi hazvisi nyore.
Tekinoroji yekubatanidza magetsi (optical fusion) yakaoma zvikuru. Sisitimu yekubatanidza magetsi inofanirwa kuona kuti photovoltaic, simba rekuchengetedza magetsi uye grid remagetsi zvinoshanda zvakachengeteka uye zvakagadzikana, uye kupwanya zvipingamupinyi zviri pakati pehardware, software uye system level.
Kune michina yakawanda mu optical storage fusion system, iyo inoda kugadzirisa dambudziko rekubatana kwe interface pakati pe hardware ne software. Midziyo inowanzobva kuvagadziri vakasiyana, dhizaini yemagetsi, kutenga michina, mashandiro, kugadzirisa matambudziko nemitengo zvichawedzera, uye chinonyanya kukosha, kutaurirana pakati pemidziyo yakasiyana kwakasiyana, vanobatanidza vanofanirwa kuziva ma protocol nema interface akasiyana.
Saka, kusanganiswa kwekuchengetedza kwemaziso hakusi kusanganiswa kuri nyore kwezvishandiso zve photovoltaic nezvishandiso zvekuchengetedza simba, asi kuvimba netekinoroji yekubatanidza yakadzika kuti iwane mhedzisiro ye1 + 1 > 2. Izvi zvinoedza simba rekubatanidza reIntegrator zvakanyanya.
3. Dambudziko rekubatanidzwa kweindasitiri rakaonekwa nemakwikwi emitengo yakaderera
Kubatanidzwa kwemasisitimu ndiyo kiyi yekuvakwa kwechiteshi chemagetsi chekuchengetedza maoptical, asi kune matambudziko akawanda mumunda wekubatanidza maoptical emuno.
Kune rumwe rutivi, hakuna makambani mazhinji ane kugona kwakabatana kwekuchengetedza optical system. Ingave tekinoroji yakabatana kana bhizinesi rakabatana, kuchengetedza simba munyika medu kuchiri muchikamu chekutanga chekuvandudzwa kwemaindasitiri. Makambani mazhinji akasimba muminda yega yega senge solar inverter, mabhatiri ekuchengetedza simba, PCS, EMS, nezvimwewo, asi makambani mashoma chete ndiwo ane masisitimu ekuchengetedza optical akabatana.
Kune rumwe rutivi, mitengo yakaderera yave kuwedzera kuipa, mabhizinesi ari kudziviswa nemitengo yakaderera. Parizvino, mutengo wekuchengetedza simba waderedzwa kubva pa2.15 yuan/Wh (mutengo weEPC) kusvika pa1.699 yuan/Wh (mutengo weEPC) kudivi remagetsi matsva emuno, mutengo uyu wave pasi zvakanyanya pemutengo wemutengo unozivikanwa neindasitiri.
Mamiriro akasiyana ane zvinodiwa zvakasiyana zvemasisitimu ekuchengetedza simba, uye hapana mwero wakabatana wekugadzira uye mutengo wemasisitimu ekuchengetedza simba, zvinogona nyore nyore kusviba.
"Iye zvino makambani ari kuda mabhatiri, uye mwero wacho ndewemasekitori zviuru zvitanhatu. Indasitiri iyi haina mwero wekuongorora wakabatana. Vamwe vagadziri vari kuda mapurojekiti ane mabhatiri ane hupenyu hwemasekitori ari pasi pezviuru zvitatu pamitengo yakaderera. Ehe, hatigone kukwikwidzana navo maererano nemutengo," akadaro mumwe mukuru wekuchengetedza simba asina simba.
"Ehe, chinhu chakakosha pakubatanidzwa kwesimba rekuchengetedza masisitimu ndechekuchengetedza kuchengetedzeka kweDC side, ndiko kuti, kuchengetedza masisitimu ebhatiri, izvo zvinoda dhizaini yakakwana yekudzivirira sisitimu," akadaro mumwe munhu. Sero, module, bhatiri cluster, manejimendi sisitimu yebhatiri, mazinga mana akabatana, dhizaini yakanaka yekudzivirira sisitimu, inogona kuziva mamiriro ekushanda kwayo munguva chaiyo, inogona kunyevera nekukurumidza, kana paine chikanganiso, inogona zvakare kuita dziviriro nhanho nhanho uye dziviriro yekubatanidza nekukurumidza.
Zvikasadaro, zvikanganiso zvidiki zvinogona kushanduka nyore nyore kuita matambudziko makuru. Mumakore achangopfuura, tsaona dzemoto dzinopfuura makumi matatu dzakaitika muSouth Korea, zvikonzero zvizhinji zvacho zvikanganiso zvekugadzirwa kwemagetsi, uye dziviriro yemagetsi inokonzerwa nekukundikana.
Kuedza uku hakugumiri ipapo, kune matambudziko ehupenyu hwebhatiri, panofanira kunge paine dhizaini yesystem yekudzora tembiricha yekuchengetedza simba. Kuenzanisa kwakasimba kwekupisa uye kuongororwa kwekuyedza, dhizaini yemidziyo yekuchengetera simba yemhepo, magadzirirwo esimba remhepo inotonhodza nezvimwewo, malink aya haana kudzorwa uye kugadzirwa zvakasimba, zviri nyore kutungamira kune kusawirirana kwekushisa kwemabhatiri e lithium mukati memudziyo, zvichiwedzera kusagadzikana kwesero.
Munyori akasangana nehurongwa hwekuchengetera simba hwe4H, apo mutsauko wekupisa kwesero wakasvika 22℃, haungokanganisi zvakanyanya hupenyu hwebhatiri chete, asiwo unowedzera njodzi yekushanda kwechiteshi chemagetsi chekuchengetedza simba.
4. Masisitimu ekuchengetedza simba angatarisirwa sei zvinobudirira?
Kubva pakusarudza hurongwa kusvika pakubatanidzwa kwehurongwa, kushanda kwakachengeteka uye mabhenefiti akanakisa ehurongwa hwese hwekuchengetedza simba zvine chekuita nekushanda nekutarisira hurongwa hwese.
Zvichienzaniswa nenzira yechinyakare yekutumira magetsi muchikamu chemagetsi chekare, manejimendi anoshanda emabhatiri nema converters muchigayo chemagetsi chekuchengetera magetsi anofanirwa kufungwa zvizere kana sisitimu yekugadzira magetsi ekuchengetedza magetsi ichitanga, nenzira iyi, kuchengetedzeka nekuchengetedza kwechikamu chemagetsi chese kunogona kuvandudzwa.
Apa ndipo panonyanya kukosha EMS (Energy Management System-RRB-, uropi hwakangwara hwechigadzirwa chekuchengetera optical,). Kuchengetedza simba kunoshanda sei nemasisitimu e photovoltaic uye ma power grids? Bhatiri pacharo rinofanira kuchaja marii, kuchaja sei, kuve nechokwadi chekuti rakachengeteka? Zvese izvi zvinoda seti yeEMS yakangwara uye inoshanda yeIntegrated Management.
Tichitora kupfava kwesystem ye photovoltaic semuenzaniso, sisitimu yekuchengetedza simba inogona kubva pakudzora kupfava kwe photovoltaic output smoothing control yekugadzira simba re photovoltaic, kuisa parameter yekupfava, EMS inotora parameter yekupfava sechinangwa chekudzora, kukurumidza kuchaja uye kuburitsa simba kunoiswa kune sisitimu yekuchengetedza simba, kuitira kuti simba rekubuda kwesystem yekugadzira simba rive pakati pehuwandu hwekuchinja kwakatemwa.
Parizvino, tsika yakakura muindasitiri iyi ndeyekuti EMS yakangwara yakavakirwa pakufanotaura kwesimba remagetsi uye hunhu hwekuchengetedza simba remasekondi maviri kuti iwane kutonga kwakanaka kwemasisitimu emagetsi, kuderedza kukanganiswa kwegridi yemagetsi, kuvandudza kugadzikana uye kuvimbika kwekushanda kwegridi yemagetsi. Panguva imwe chete, nzira yekubatanidza gridi yemagetsi yemilisekondi imwe chete yakavakwa pakati peBMS, PCS neEMS kuchengetedza bhatiri nehurongwa hwese.
Pamusoro pezvo, EMS yepamusoro-soro inogonawo kuwana multi-energy Digital Integrated Management, kufukidza kwakazara kwebvudzi, kutapurirana, kugoverwa, pamwe nenzvimbo yakazara.
