BESS Frequency Regulation: Nigute Wapima MW na MWh

Kugenzura inshuro nyinshiikoresha ingufu za batiri yihuta, ikosora ingufu kugirango ikosore ubusumbane buke - hagati yigihe cyo gutanga amashanyarazi nibisabwa. Iyo gride inshuro iguye, sisitemu yo kubika ingufu za batiri isohora imbaraga zikora. Iyo inshuro izamutse, irishyuza kandi ikurura imbaraga. Umugenzuzi w'ibihingwa,sisitemu yo gucunga ingufu, sisitemu yo guhindura amashanyarazi hamwe na sisitemu yo gucunga bateri basangiye aka kazi, kandi buriwese arashobora kwigenga kugabanya igisubizo.

Umuvuduko nigice cyoroshye. Inverter yose igezweho - ishingiye kuri BESS irashobora guhindura imbaraga zikora mumasegonda cyangwa munsi. Niki cyemeza niba umushinga - umushinga wamabwiriza winjiza amafaranga ntagushimishije: burya ingufu zikoreshwa mubyukuri muri leta yemerewe - ya idirishya ryishyurwa -, uko gutinda kwicara hagati ya metero na inverter, niba ikimenyetso cyamabwiriza kiyobora bateri kugeza kumpera yikigereranyo cyacyo, kandi niba uruganda rwatsinze ikizamini cya sisitemu yo kugerageza mbere yo kugerageza.

Aka gatabo kanyuze mubisubizo ubwabyo, ingano yimibare hamwe nurugero rwuzuye rwakazi, uburyo bwo gutsindwa bugaragara mugihe cyo gutangiza.

Ni ubuhe butumwa bukoreshwa na BESS?

Imirongo ya gride yerekana igihe nyacyo - igihe kiringaniye hagati yisekuru nogukoresha. Iyo ibisabwa birenze ibisekuruza, inshuro ziragabanuka. Iyo ibisekuru birenze ibisabwa, inshuro zirazamuka. Imirongo - igenga umutungo ihindura imbaraga zayo zifasha kugarura iyo mpirimbanyi.

BESS irashobora kwimuka mubyerekezo byombi:

• Igisubizo kidahwitse:bateri isohora ingufu muri gride.
• Igisubizo kirenze urugero:bateri yishyuza kandi ikuramo imbaraga muri gride.

Sisitemu yo muri Amerika ya ruguru muri rusange ikora kuri Hz 60; byinshi muburayi, Ubwongereza nizindi sisitemu nyinshi zikoresha 50 Hz. Imipaka ntarengwa yo gukora, imipira ipfuye hamwe nibisabwa kugirango bisubizwe biva kuri kode ya grid ikoreshwa hamwe na sisitemu ya sisitemu, ntabwo biva kubatanga bateri.

Itandukaniro rimwe rikwiye gukosorwa hakiri kare, kuko ritwara ibintu byose hepfo: kugenzura inshuro ni aimbaragaserivisi, kugarura imbaraga ni aningufuserivisi. Amabwiriza arasaba imbaraga zihuse, zukuri, zasubiwemo imbaraga zapimwe mumasegonda niminota. Ububiko busaba ibisubizo birambye bipimwa mumasaha. BESS imwe irashobora gukora byombi, ariko igomba kuba nini kandi igenzurwa kuri - kandi imirimo yombi izahatanira leta imwe ishinzwe.

Impamvu Imiyoboro ya Gride ihinduka

Amashanyarazi akoreshwa mugihe kimwe cyabyaye, bityo kudahuza bikagaragara ako kanya nko gutandukana inshuro. Impamvu zisanzwe zirimo urugendo rwa generator, ikosa ryogukwirakwiza, umutwaro munini winganda ufungura, impinduka zitunguranye mubishobora kuvugururwa, guhanura ikosa, ibyabaye bihuza cyangwa umutwaro munini uhuza. Ingano n'umuvuduko wubusumbane butwara Igipimo cyimpinduka za Frequency, ubujyakuzimu bwa nadir yumurongo nubunini bwimbaraga zo gukosora sisitemu ikeneye.

Imashini itanga amashanyarazi itwara misa izunguruka isanzwe irwanya impinduka zitunguranye. Imirasire y'izuba, ibihingwa byinshi byumuyaga na BESS ihuza binyuze mumashanyarazi aho. Nka inverter - ibikoresho bishingiye gusimbuza igice cya parike ya syncronique, inertia idahinduka idasanzwe irahari, kandi byinshi mubisubizo bigomba kuva muburyo bugenzurwa neza na inverter igenzura hamwe nububiko bwamasezerano. Amabwiriza ya NERC yo kwizerwa kuriBPS - ihuza ingufu za batiri hamwe ninganda zivanzeifata inshuro zihuse nkubushobozi BESS igomba kuba ishobora gutanga, kandi ikanasaba ko hajyaho inyungu zidasanzwe hamwe nigitambara cyapfuye muburyo bwo kwishyuza no gusohora, hamwe ninzibacyuho hagati yabo.

Uburyo BESS Frequency Regulation ikora: Icyabaye, Isegonda nisegonda

Ingingo nyinshi zisobanura kugenzura. Nibyiza cyane gukurikira ibyabaye binyuze mubihingwa. Ingengabihe ikurikira ni ishusho yakozwe ku gihingwa cya MW 10 kuri sisitemu ya 50 Hz isubiza igisubizo cyaho kiranga - imibare irahagarariwe, ntabwo ari ibisobanuro.

Ibintu bibiri mururunigi bikwiye kwibandwaho, kuko niho imishinga yananiwe.

Ubwa mbere, gutandukana - kugeza - guhindura imbaraga. Igisubizo kidasanzwe cyanditswe nkukoimbaraga zo gusubiza=gutandukana inshuro × kugenzura inyungu. Iyo ni isano isanzwe yo gusobanura igitekerezo, ntabwo ari igishushanyo mbonera. Ishyirwa mubikorwa nyaryo rikeneye amasezerano yikimenyetso, nomero yumurongo wa nomero, ijanisha ryamanutse ryerekanwe kumashanyarazi asobanuwe, umurongo wapfuye, kwiyuzuzamo imbaraga zagenwe, imipaka ntarengwa, hamwe na clamp zikomeye ziva muri SOC nubushyuhe. Mu karere k'umugabane wa Burayi uhuza, urugero, ENTSO - E.politiki kumitungo ya FCRbisaba ko gukora bidatinda muburyo bwubukorikori kandi bigatangira bitarenze amasegonda abiri nyuma yintambwe yumurongo, ko FCR yuzuye itangwa kuri 200 mHz itandukanijwe, kandi ko umurongo wapfuye hamwe no kutumva neza biguma muri mHz 10. Ibyo bipimo bine - byerekanwe, gutemba, umurongo wapfuye, kwiyuzuza - nibyo injeniyeri yikizamini azagenzura.

Icya kabiri, kugabana ubutware. Urutonde rurerure rwo kugenzura ibintu ntacyo rubwira umusomyi ntacyo ashinzwe mugihe igisubizo cyatinze. Mubyububiko bwinshi bwibimera gutandukana bisa nkibi:

• PCS:igipimo cya ramp, gukurikirana neza hafi ya zeru, kwishyuza nta - kugeza - gusohora inzibacyuho, kugendana amakosa - unyuze. Ubunebwe hano mubisanzwe ni milisegonda kandi ni gake ikibazo.
• Umugenzuzi w'ibihingwa / EMS:guta umurongo, gupfira, gukosora SOC, kugabana hagati ya serivise zegeranye, imyitwarire yo gutakaza itumanaho. Aha niho hategurwa amakimbirane menshi.
• BMS:kwishyurwa ako kanya no gusohora imipaka ntarengwa, ishingiye kuri voltage ya selile, ikigezweho, ubushyuhe na SOC. Irashobora guceceka ubushobozi bwawe bwasezeranijwe mo kabiri mugitondo gikonje.

Inzitizi ya BMS ikwiye kwitabwaho murwego rwo gushushanya aho kugerageza. Utugingo ngengabuzima twa Litiyumu twemera ubushyuhe buke cyane ku bushyuhe buke, bityo igihingwa kimeze neza kuri dogere 25 gishobora kudashobora gutanga amabwiriza yagabanutse kuri dogere 5 kugeza igihe paki zishyushye. Biremeweimikorere yubushyuhe bwa baterina sisitemu yubushyuhe bwo kuyifata rero ni igice cyumurongo - igishushanyo mbonera cya serivisi, ntabwo ari igitekerezo.

Igenamigambi ryinshyi vs Igisubizo cyihuse: Aho umupaka wicaye

Ijambo ryinshuro ntirisanzwe kwisi yose, kandi ibicuruzwa byubucuruzi ntibishobora guhinduka. Sisitemu yuburayi ikoresha ububiko bwa Frequency Containment Reserve, Automatic Restoration Reserve Reserve hamwe nintoki za Restaurant Restaurant; amasoko ya Nordic yagabanije FCR mubikorwa bisanzwe - nibikorwa byo guhungabanya umutekano. Amasoko yo muri Amerika ya ruguru akoresha igisubizo cyibanze cya Frequency Response, Amabwiriza Hejuru na Hasi, Igisubizo cyihuse, Igisubizo cyihuse hamwe nububiko bwihutirwa. Imikorere ikarita kuri buri gitekerezo, nkuko biri hepfo.

Igishushanyo mbonera kiragaragara. Ibicuruzwa byihutirwa - ibicuruzwa ntibisanzwe byitwa, ingufu rero kuri activation ni nto ariko igihe cyo gutanga gisabwa ni kirekire. Ikimenyetso gikomeza gukurikiranwa cyitwa buri gihe, bityo ibyinjira ni byinshi kandi drift ya SOC niyo yiganje. Batare imwe ya MW 10 ni imashini itandukanye muri buri kibazo.

Igenzura rya BESS Frequency Igenzura, Ubukererwe na Telemetrie

Ubwubatsi busanzwe bukoresha metero metero control umugenzuzi wibimera cyangwa EMS →sisitemu yo guhindura imbaraga→ bateri yamashanyarazi, hamwe nibitekerezo bisubira inyuma munzira imwe igana SCADA. Urutonde rwibisobanuro kuri urwo ruhererekane ni rurerure, ariko ibintu bitatu bibara byinshi byambere - kugerageza ikizamini cyatsinzwe:

1. Kurangiza - kugeza - gutinda kurangira. Igipimo cyo kuvugurura ibipimo, gushungura umwanya uhoraho, protocole yo gutora intera nigihe cyo kugenzura ibihe byose bikurikirana.
2. Ibikoresho bipfuye hamwe n'ibikoresho, ikunze gushyirwa ahantu hatatu (PCS, umugenzuzi wibimera, EMS) kandi igomba gushyirwaho muburyo bumwe murimwe.
3. Itumanaho - imyitwarire yo gutakaza, kubera ko umukoresha azabigerageza. Niba uruganda rufite aho ruheruka, rugera kuri zeru cyangwa rukagaruka kumurongo waho ni amahitamo yamasezerano, kandi agomba guhuza namategeko yisoko.

Inkuru isanzwe yo gutangiza ikora gutya: PCS isubiza munsi ya ms 200 ku ntebe, ariko metero yatowe hejuru ya Modbus TCP kuri 1 s, umugenzuzi akora ms 500 cycle hamwe na 1 s filteri, kandi igisubizo cyibiti cyapimwe kigera hafi yamasegonda abiri nyuma yintambwe. Inverter ntabwo yigeze iba ikibazo. Kwita protocole - Modbus TCP, IEC 61850, DNP3, cyangwa umukoresha {{9} interface Imigaragarire yihariye - nayo ntabwo ihagije; umushinga ugomba gukosora ingingo zamakuru, kuvugurura ibipimo, kugenzura ubuyobozi nimyitwarire yo kunanirwa mukwandika.

MW vs MWh yo kugenzura inshuro

Ikosa rikunze kugaragara ni kugura sisitemu kurwego rwa MW. Urutonde rwa MW rushyiraho ingufu uruganda rushobora gutera cyangwa gukuramo icyarimwe. Urutonde rwa MWh rushyiraho igihe rushobora gukomeza kubikora. Niba itandukaniro hagatiimbaraga nimbaragairacyari fuzzy, ikemure mbere yo gusoma igice gikurikira, kuko ibintu byose biri munsi ni imibare yubatswe kuri yo.

Umubano wo gutangira uroroshye:

Ingufu zisabwa=imbaraga zo kugenzura × igihe cyo gutanga

Ntabwo na none ari igisubizo. Nameplate MWh ntabwo ikoreshwa MWh, kandi ikinyuranyo mubisanzwe ni ibintu bibiri cyangwa byinshi.

Nigute Wapima BESS yo kugenzura inshuro

Ubushobozi bwo hasi burashobora gufatwa nigipimo cya PCS yishyurwa, igipimo cya BMS ntarengwa, imipaka itumizwa mu mahanga, ubushobozi busigaye cyangwa ibisabwa kurubuga. Kubicuruzwa bisa, ibyerekezo byombi bigomba kuboneka kubushobozi bwasezeranijwe icyarimwe - imbogamizi zihuza mubisanzwe ntanumwe wagereranije.

Intambwe ya 3: Kora ingufu zikoreshwa, hanyuma ukore usubire inyuma kurutonde

Aha niho urugero rwakazi rwinjiza.Imibare ikurikira ni urugero rwiza rwo gusobanura uburyo; ntabwo aribisobanuro kandi ntibigomba gukoreshwa kumushinga udafite amategeko agenga ibicuruzwa.

Ibisabwa:10 MW ihuza ibipimo, iminota 15 yo gukomeza gutanga byuzuye mubyerekezo byombi.

• Ingufu aho zihurira, buri cyerekezo: 10 MW × 0,25 h =2.5 MWh.
• Inzira yo gusohora (PCS, transformateur, abafasha) hafi 94%: selile zigomba gutanga hafi2.66 MWh.
• Kwishyuza inzira hafi 94%: gukuramo 2,5 MWh kuri metero ishyira hafi2.35 MWhmuri selile.
• Igiteranyo cya DC cyose kigomba kwicara imbere mu idirishya ryemewe:≈ 5.0 MWh- inshuro ebyiri nimero ya naive, kubera ko ibicuruzwa bisa bikenera ingufu zabitswenaicyumba cyubusa icyarimwe.
• Idirishya ryemewe rya SOC ya 10-90% (80% ikoreshwa): icyapa cyizina mugitangira cyubuzima Birenze cyangwa bingana na 5.0 / 0.8 ≈6.3 MWh.
• Garanti yemeza ko 70% yagumana ubushobozi mumwaka wa 10, nta yongerewe: icyapa cyamazina ≈ 5.0 / (0.8 × 0.7) ≈8.9 MWh.

Ibisabwa rero "15 - umunota" ku ruganda rwa MW 10 bitanga ingufu - kugeza - igipimo cy’amashanyarazi ahantu hagati ya 0,63 na 0.89 MWh kuri MW - ntabwo ari 0.25 umutwe w’imibare isobanura. Icyemezo cyubwubatsi noneho kirasobanutse: gura hafi MW 9h kumunsi wambere, wemere capex kandi wishimire igipimo C -; cyangwa kubaka hafi 6.5 MWh kandi wiyemeze kongera mumwaka wa gatanu cyangwa gatandatu. Byombi birashobora kwirwanaho. Ikidashobora kwirwanaho ni ugusubiramo 2.5 MWh. Ongeraho urubuga - gutondekanya hejuru - gukomeza dogere 40 ibidukikije bizatwara ubushobozi bukoreshwa no kuzamura umutwaro wabafasha, kandi inshingano zavuyemo nigice kinini cyimpamvusisitemu yo gukonjeshani inshuro - icyemezo cyamabwiriza aho kuba imashini.

Intambwe ya 4: Hitamo idirishya rya SOC nkana

Intego yegereye hagati yurwego rwemewe irinda ibyerekezo byombi, kandi kubicuruzwa bisa nibisanzwe bitangirira. Ni intangiriro, ntabwo ari itegeko. Intego nyayo ihinduka hamwe nibimenyetso byerekana amateka, kubogama kwa serivisi, amategeko yo gukemura ingufu, chimie, imiterere ya garanti, izindi porogaramu zashyizwe hamwe nibiteganijwe nabi - ibyabaye igihe. Umugenzuzi agomba guhindura intego; ijanisha rihamye rikomeye - yanditse kuri komisiyo ni isoko izwi yo gutinda - ubuzima buke.

Intambwe ya 5: Shyiramo gutesha agaciro no kurangiza - ya - ubuzima

Igihingwa cyujuje ibisabwa mugihe gishya gishobora kunanirwa mumwaka wa gatandatu.

Intambwe ya 6: Wigane amakuru yukuri

Kwigana kurwanya inshuro nyinshi cyangwa kohereza amakuru nuburyo bwizewe bwo gushushanya buraboneka, ariko ibyifuzo nta gaciro bifite nta bipimo byacyo. Ubushakashatsi bwunganirwa buvuga imibare yamakuru yakoreshejwe kandi hejuru yicyerekezo, intera y'icyitegererezo, SOC yambere na politiki iherutse, ibipimo byo kwemererwa, hamwe nibibazo byimikorere. Nibura ingirakamaro: byibuze amezi cumi n'abiri yikimenyetso cyatangajwe na nyirubwite ku cyemezo cyacyo kavukire, koresha uhereye ku ndangagaciro nyinshi za SOC, hamwe no kunanirwa bisobanurwa nk'intera iyo ari yo yose aho uruganda rudashobora gutanga ingufu zasezeranijwe mu cyerekezo cyombi. Impuzandengo ya buri kwezi izahisha neza Windows ngufi igutwara ubwishyu.

Ubuyobozi bwa SOC kubisubizo byinshyi

Amabwiriza yimura bateri kure yintego zayo. Umugenzuzi akeneye ingamba ziherutse: kwishyuza gahoro cyangwa gusohora hagati yibyabaye, offset ikoreshwa kumabwiriza agenga amabwiriza, cyangwa gucuruza kumasoko yingufu kugirango agarure aho akorera. Intego ni simmetrike - imbaraga zabitswe zihagije zo gusohora iyo inshuro ziguye, ubushobozi bwubusa bwo kwishyuza iyo buzamutse.

Ibiranga kunanirwa uburyo ni ukuzura. Irasa nkiyi mu myitozo: ikimenyetso hamwe na bito bito bikomeje kubogama bigenda SOC hejuru kugeza nyuma ya saa sita; kuri 85% igihingwa ntigishobora kwemera amabwiriza yuzuye yo hasi; amanota yimikorere yabakoresha aragabanuka, kandi kubera ko amanota akoreshwa mubushobozi bwose bwasezeranijwe, igihombo cyinjira ni kinini cyane kuruta ingufu zirimo. Nta kintu cyatsinzwe. Nta gutabaza. Igishushanyo cyatekereje gusa ko ikimenyetso ari ingufu - kidafite aho kibogamiye.

PJM, nkurugero, itanga ikimenyetso cyihuse cya RegD hamwe nikimenyetso cya RegA gahoro, kandi kutabogama kubutunzi bwihuse birateganijwe aho byemewe - amategeko asobanutse hamwe nigishushanyo mbonera cyerekana muri iki giheIgitabo cya PJM 12: Kuringaniza ibikorwa, hamwe nibimenyetso byamateka amakuru yatangajwe. Gerageza igitekerezo kirwanya ayo makuru aho kuyaragwa. Ku mugabane w’Uburayi ikibazo kimwe gikemurwa mu buryo bweruye: ENTSO - E ifata bateri nk’ibigega by’ingufu bigarukira - kandi bisaba igitekerezo cy’imicungire ya SOC - hiyongereyeho ikigega gito cy’ingufu, cyanditswe mbere y’ibisabwa, igihe ntarengwa cyo gukora iminota 30 kuri ibyo bice mu gihe cyo kuba maso.

Kugabanuka kwa Bateri munsi yinshingano

Kugenzura inshuro bisobanura ibintu byinshi bito, bikunze kugenda. Kwambara bivamo biterwa ningufu zose zinjiza, ubujyakuzimu bwa buri cyiciro, kwishyuza no gusohora, ubushyuhe bwakagari, impuzandengo ya SOC, igihe cyakoreshejwe hafi yimipaka ya SOC, imikorere ikonje, chimie nimyaka ya kalendari.

Kugenzura ibizunguruka bikunze kuba byoroheje kuri buri gice cyinjiza kuruta gusohora inshuro nyinshi, ariko ibyo ni imyumvire, ntabwo ari garanti, kandi ntabwo arimpamvu yo kwirengagiza ikibazo: NRELibikorwa byubuzima bwimikorereyerekana ubushobozi bugenda butwarwa nubushyuhe, C - igipimo, ubujyakuzimu bwo gusohora hamwe nuburyo bwo kwishyuza, hamwe na kalendari - uburyo bwo gusaza bukomeza utitaye kungingo ingirabuzimafatizo zizunguruka. Batare ifatiye kuri SOC nubushyuhe bwo hejuru kugirango igumane hejuru iboneka irashaje no kumunsi utuje. Inkomoko iboneye kumushinga runaka ni selile cyangwa sisitemu itanga ubuzima bwumurongo hamwe na garanti yinjiza, soma hamwe.

Icyitegererezo cyubucuruzi kigomba gutwara ikiguzi cyo gusimbuza cyangwa kongera, ibicuruzwa byinjira muri garanti, kuzenguruka - igihombo cyurugendo, ingufu zikonje, ubushobozi butaboneka, ibihano byimikorere ningufu zo kugarura SOC. Igisubizo cyihuse ntabwo gisobanura igiciro gito cyo gukora.

Kwipimisha no Gukora Ikizamini cyo Kugenzura Inshuro

• Porotokole ya SCADA, ingingo zamakuru, icyitegererezo hamwe na telemetrie
• Kwipimisha kure, gusigara hamwe na O&M

Izi zitanga impinduka mugihe zidasobanutse neza

• Igisubizo - ibisobanuro byigihe - byapimwe aho, hamwe nikizamini
• Itumanaho - imyitwarire yo gutakaza
• Ninde ufite SOC iherutse ingufu nigiciro cyayo
• Niba kuboneka bipimirwa kurwego rwibimera cyangwa portfolio

Gukemura ibi bisobanuro byinshi nibyo bituma abayitanga batanga umurongo wa serivisi nyirizina aho kugena rusangesisitemu ya batirino kuvumbura icyuho mugihe cyo gutangiza.

Ibibazo Bikunze Kubazwa

Nibihe byihuse BESS ishobora gusubiza gutandukana?

PCS ubwayo isanzwe isubiza neza munsi yisegonda. Igisubizo cyibimera kigeragezwa kiratinda, kubera ko igipimo cyo kuvugurura metero, kuyungurura, gutora protocole hamwe nigihe cyumuzenguruko wongeyeho - amasegonda abiri kurangira birangiye birasanzwe mubihingwa bidakorewe. Ibicuruzwa bisabwa biratandukanye: Amategeko ya ENTSO - E yo ku mugabane w’Uburayi asaba ko ibikorwa bya FCR bitangira bitarenze amasegonda abiri nyuma yintambwe yumurongo kandi bigera kuri enterineti byuzuye mumasegonda 30 mugihe cyo gutandukana 200 mHz, mugihe andi masoko agaragaza imyirondoro itandukanye.

Nangahe MWh inshuro - amabwiriza BESS akeneye?

Kurenza imbaraga × igihe. Kubicuruzwa bya MW 10 bihwanye na 15 - byateganijwe gutangwa, kubara byerekana hejuru yubutaka buri hagati ya 6.3 MWh mugitangira cyubuzima na 8.9 MWh niba ushaka kuzuza ibisabwa nyuma yubuzima utarinze kwiyongera - kurwanya MW 2.5h uhereye kuri formulaire ya naive. Kugwiza biva mugukenera ingufu zabitswe hamwe nicyumba cyumutwe, idirishya rya SOC ritari 100%, igihombo cyo guhinduka hamwe nubushobozi burashira.

Ni ubuhe buryo bwo kwishyurwa bukoreshwa mugutunganya inshuro?

Kuri serivisi ihuriweho, hafi yidirishya ryemewe, bityo ibyerekezo byombi bigumaho. Intego nyayo igomba kwimuka hamwe nibimenyetso bibogamye, serivisi asimmetrie, chimie, imiterere ya garanti hamwe na serivise iyo ari yo yose - mu buryo bukomeye, ntabwo ari numero ikomeye -.

Ese imbaraga zo kugenzura inshuro - ntaho zibogamiye?

Ntabwo byizewe. Ibimenyetso bimwe byashizweho kugirango bihuze kutabogama hejuru yidirishya rigufi, kandi amasoko amwe atuma iryo huzwa risabwa. Kubogama guhoraho nimpamvu isanzwe itera kwiyuzuzamo SOC, kubwibyo rero igitekerezo kigomba kugeragezwa kubimenyetso byerekana amateka yabatangajwe mbere yuko bishushanya.

Ese kugenzura inshuro byangiza bateri?

Irasaza, nkinshingano iyo ari yo yose. Kugabanuka, gusiganwa ku magare bikunze kuba byoroheje kuri MWh yinjira kuruta gusohora inshuro nyinshi, ariko ibyinjira byose, C - igipimo, ubushyuhe hamwe nimpuzandengo ya SOC byose bigenda bishira, kandi gusaza kwa kalendari birakomeza utitaye. Ikibazo cyingenzi mubucuruzi ntabwo ari ukumenya niba kwambara bibaho ahubwo niba inshingano iguma imbere mu ibahasha yinjira muri garanti.

BESS imwe irashobora gukora inshuro nyinshi kugenzura no kugarura imbaraga?

Mubyukuri yego, kandi nibisabwa muriakamaro - igipimo cyimishinga. Ariko ingufu zabigenewe zabitswe ntizishobora kuboneka ku isoko, kandi kubika bigabanya idirishya rya SOC serivisi ishinzwe kugenzura ishobora gukoresha. Ingano y'imirimo yombi mu buryo bweruye, hanyuma uhitemo mbere uwo itanga mugihe cy'amakimbirane.

Incamake

BESS inshuro nyinshi ituma umurongo wishyuza cyangwa ugasohora vuba kandi neza mugusubiza itangwa - risaba ubusumbane. Umuvuduko, ibyerekezo byombi hamwe no gukurikirana neza nibyiza nyabyo, kandi nigice cyoroshye cyumushinga kubona neza.

Ibice byerekana ibizavamo ni imbaraga zikoreshwa imbere yidirishya rya SOC, iherezo - kugeza - itinda ryurwego rwo gupima no kugenzura, ingamba za SOC zirokoka ikimenyetso kibogamye, icyitegererezo cyo gutesha agaciro cyujuje amasezerano mumwaka wa cumi, hamwe nigishushanyo cyahagaritswe nigitabo cyisoko kizakoreshwa mubizamini. Shakisha ibikorwa byubu ukoresha, kora simulation hamwe nibitekerezo byavuzwe hamwe nibisabwa, hanyuma ushire imibare kumpera. Nibyo bihindura amabwiriza ya frequence kuva mubushobozi rusange BESS mumasezerano - umushinga witeguye.
