1. Cov qauv siv hluav taws xob tsim hluav taws xob tsis tsim nyog rau kev siv hluav taws xob loj loj
Piv txwv
Kev tsim hluav taws xob hauv hluav taws xob yog tsim los ntawm cov chaw nres tsheb hauv nruab nrab xa hluav taws xob rau cov neeg siv, thaum nrog kev sib koom ua ke loj ntawm kev faib tawm (DG) xws li hnub ci photovoltaics (PV), cua zog, thiab lwm yam., lub network faib tau maj mam hloov los ntawm unidirectional passive network mus rau ib tug bidirectional active network. Qhov kev hloov pauv no ua rau nws nyuaj rau cov qauv siv hluav taws xob tsim hluav taws xob thiab kev npaj ua kom tau raws li qhov xav tau tshiab. Piv txwv li, nyob rau hauv Shandong, Henan thiab lwm qhov chaw, vim qhov kev loj hlob sai ntawm cov khoom siv hluav taws xob uas muaj peev xwm ua tau, qee lub zog hauv cheeb tsam tau ntsib qhov tshwm sim rov qab hnyav dhau, uas yog, thaum lub sij hawm siab tshaj ntawm photovoltaic fais fab tuag, hluav taws xob ntau dhau raug xa mus. rov qab los ntawm sab qis-voltage mus rau sab high-voltage, uas coj cov siab ntxiv rau hauv daim phiaj fais fab.
2. Kev npaj kev faib tawm hauv lub network yuav tsum tau hloov mus rau ntau qhov xwm txheej yuav tshwm sim
Piv txwv
Nrog rau qhov kev faib ua feem ntau ntawm cov hluav taws xob faib tshiab, qhov tsis paub tseeb uas tau ntsib los ntawm kev faib network kuj tau nce ntau ntxiv. Yuav kom daws tau qhov tsis paub tseeb thiab qhov tsis txaus ntseeg no, kev npaj cov phiaj xwm kev faib tawm yuav tsum tau hloov pauv los ntawm kev txiav txim siab ib txwm muaj rau kev npaj yuav tshwm sim uas xav txog ntau yam xwm txheej. Qhov no txhais tau tias tsis tsuas yog ntsuas qhov kev ua tau zoo ntawm daim phiaj hluav taws xob nyob rau hauv cov xwm txheej zoo li qub, tab sis kuj simulating cov lus teb dynamic nyob rau hauv cov huab cua sib txawv, cov qauv thauj khoom, thiab lwm yam. Piv txwv li, Cov Lus Qhia rau Kev Ntsuas Kev Ntsuas Cov Peev Xwm Muaj Peev Xwm ntawm Cov Khoom Siv Hluav Taws Xob Txuas Txuas rau Fais Grids txhais ntau yam kev ntsuas rau kev nqa lub peev xwm ntawm cov xaim hluav taws xob, thiab xav tau ntau yam kev ntsuam xyuas xws li kev ntsuas thermal stability thiab kev ntsuas hluav taws xob sib txawv los xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm. daim phiaj zog.
3. Lub kaw lus ua haujlwm nyob rau hauv txoj haujlwm nyuaj, ua rau nws nyuaj rau kev hloov kho rau kev tsim kho lub zog tshiab
Piv txwv
Qhov sib ntxiv ntawm cov khoom siv hluav taws xob tshiab tau hloov pauv cov qauv qub ntawm lub zog hluav taws xob, ua rau lub zog ua haujlwm ntau dua. Tshwj xeeb tshaj yog nyob rau hauv siab nkag mus, cov tsoos "qhov chaw load dynamic" qauv teem sij hawm yog tsis siv, thiab yog hloov los ntawm ib tug complex "qhov chaw load kev sib cuam tshuam". Qhov no yuav tsum muaj lub zog hluav taws xob kom muaj qhov hloov tau yooj yim dua los hloov kho sai sai rau kev ua haujlwm. Piv txwv li, nyob rau hauv ib co cheeb tsam, thaum ib tug loj tus naj npawb ntawm faib photovoltaics yog generated ib txhij, nws yuav ua rau muaj teeb meem xws li high voltage grid voltage los yog unstable zaus, cuam tshuam rau stability ntawm tag nrho cov system.
4. Kev sib tw ntawm kev tswj hluav taws xob thiab zaus
Piv txwv
Tom qab kev koom ua ke ntawm kev faib cov photovoltaics, tshwj xeeb tshaj yog thaum lub sij hawm muaj zog tshav ntuj, qhov hluav taws xob ntawm qhov kawg ntawm cov khoom siv hluav taws xob tau nce siab tshaj qhov kev tso cai, yog li cuam tshuam rau kev ntseeg siab ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob zoo. Tsis tas li ntawd, vim qhov sib cuam tshuam thiab hloov pauv ntawm DG cov zis, nws kuj ua rau muaj kev hem thawj rau qhov kev ruaj ntseg ntawm qhov system. Yog li ntawd, cov cuab yeej ntse inverter yog dav siv los tswj cov qib voltage los ntawm kev kho lub zog tso zis; Nyob rau tib lub sijhawm, cov tswv yim tswj hwm qhov hluav taws xob siab tshaj plaws xws li Reactive Power Compensation (RPC) cov cuab yeej yuav tsum tau txais los ua kom muaj kev ua haujlwm zoo ntawm daim phiaj hluav taws xob.
5. Rov qab overload thiab davhlau ya nyob twg overvoltage teeb meem
Piv txwv
Kev siv hluav taws xob photovoltaic feem ntau yog siv nyob rau hauv cov cheeb tsam tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam nyob deb nroog lossis suburban ntawm cov nroog, uas tuaj yeem ua rau muaj kev cuam tshuam loj heev hauv cheeb tsam - cov hluav taws xob ntau dhau thaum nruab hnub yuav ntws rov qab mus rau qib siab dua substation raws cov kab feeder. Yog hais tias qhov no ntawm lub hwj chim tshaj qhov tsim muaj peev xwm ntawm txoj kab, nws yuav ua rau lub npe hu ua 'rov qab overload'. Tsis tas li ntawd, rau cov neeg siv kawg uas nyob deb ntawm lub zog hluav taws xob, qhov hluav taws xob uas lawv tau ntsib yuav nce ntxiv vim qhov ntxiv tam sim no tsim los ntawm photovoltaic array, tsim "terminal overvoltage", uas ua rau muaj kev pheej hmoo rau cov khoom siv kev nyab xeeb.
6. Nyuaj hauv kev thauj khoom forecasting thiab teem caij
Piv txwv
Ib qho ntawm cov teeb meem tseem ceeb tam sim no yog qhov nyuaj ntawm kev kwv yees, tswj, thiab teem caij lub zog tshiab. Cov txiaj ntsig ntawm cov khoom siv hluav taws xob faib yog nyob ntawm tej yam ntuj tso xws li hnub ci siv zog thiab cua ceev, uas nyuaj rau kev kwv yees kom raug. Yog li, cov txheej txheem kev kwv yees uas twb muaj lawm tsis tuaj yeem ntes tau qhov tseeb ntawm DG, uas cuam tshuam rau tag nrho cov sijhawm teem sijhawm ua haujlwm ntawm daim phiaj hluav taws xob. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb tab tom tshawb nrhiav kev siv cov thev naus laus zis tshiab xws li kev tshuaj xyuas cov ntaub ntawv loj thiab kev kawm tshuab algorithms los txhim kho DG qhov tseeb dua thiab cov qauv kev twv huab cua.
7. Cov qauv kev lag luam thiab kev txhawb nqa nyiaj txiag
Piv txwv
Kev nqis peev thiab kev ua haujlwm ntawm cov tshuab hluav taws xob faib tawm tseem tsis tau paub tab, tsis muaj kev txhawb nqa nyiaj txiag ruaj khov mus ntev thiab rov qab los. Ntawm qhov tod tes, tus nqi pib ntawm kev tsim kho yog tus nqi siab, nrog rau kev yuav khoom, kev teeb tsa thiab commissioning, thiab cov nqi kho tom ntej; Ntawm qhov tod tes, vim muaj kev hloov pauv hauv cov cai thiab cov cai thiab kev nrawm nrawm ntawm kev ua haujlwm thev naus laus zis, cov tub ua lag luam ntsib teeb meem kev lag luam tseem ceeb. Tsoom fwv yuav tsum qhia txog cov cai tseem ceeb los txhawb cov peev txheej hauv zej zog kom nkag mus rau hauv daim teb no thiab tsim kom muaj kev faib nyiaj tau los tsim nyog los xyuas kom muaj kev loj hlob ntawm cov haujlwm.
8. Kev tswj hwm thiab kev tswj xyuas tshuab
Piv txwv
Lub tshuab rau kev tswj hwm thiab saib xyuas cov tshuab hluav taws xob loj loj tsis tau paub tab txaus. Nrog ntau thiab ntau lub zog tsim hluav taws xob me me txuas nrog rau daim phiaj, yuav ua li cas thiaj li khaws cov ntaub ntawv zoo, saib xyuas cov xwm txheej hauv lub sijhawm, thiab teb raws sijhawm tau dhau los ua qhov teeb meem ceev kom daws tau. Tam sim no, txawm hais tias muaj qee qhov kev sim ua ntej, xws li kev siv cov chaw taws teeb tswj raws li Internet ntawm Yam (IoT) platforms, tag nrho nws tseem nyob hauv nws cov me nyuam mos. Nyob rau hauv lub neej yav tom ntej, kev tshawb fawb ntxiv thiab kev txhim kho ntawm cov thev naus laus zis thiab cov cuab yeej tsim nyog yuav tsum tau txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm lub system.
9. Cov qauv txheej txheem thiab kev sib koom ua haujlwm
Piv txwv
Tam sim no, tsis muaj cov qauv sib koom ua ke rau kev faib hluav taws xob nkag mus rau hauv kev lag luam, thiab muaj teeb meem kev sib raug zoo ntawm cov khoom los ntawm cov tuam txhab sib txawv. Qhov no txhais tau hais tias txawm nyob rau hauv tib lub teb chaws, tej zaum yuav muaj inconsistencies nyob rau hauv interfaces, uas ua rau kom qhov nyuaj ntawm qhov project. Yog li ntawd, nws yog ib qho tsim nyog los tsim kom tiav cov txheej txheem ntawm lub teb chaws thiab thoob ntiaj teb cov qauv los tsim cov txheej txheem kev nkag mus rau DG thiab cov kev tsis sib xws, thiab txhawb kev sib koom ua ke ntawm ntau yam khoom.
