Kev tswj ntau zaus, tseem hu ua ntau zaus hloov kho, yog ib qho kev tswj tsis siv neeg uas ua rau muaj qee yam kev sib raug zoo thiab muaj zaus. Kev tswj kom zaus yog qhov kev ntsuas tseem ceeb los tswj kev sib npaug ntawm cov khoom siv fais fab, thiab nws lub hom phiaj tseem ceeb, thiab cov zaus muaj kev ruaj ntseg ntawm lub zog hluav taws xob. Cov ntsiab lus tseem ceeb ntawm kev hloov kho hauv lub zog hluav taws xob hloov kho lub zog tsim tawm thiab ua cov kev tswj hwm kev thauj khoom. Raws li cov kev hloov kho sib txawv thiab muaj peev xwm kho tau, muaj cov kev hloov kho zaus ua ntu zus ua ke, cov zaus thiab tertiary zaus kev hloov kho. Cov kev hloov kho lub zog hluav taws xob yog qhov tseem ceeb ntawm kev ua lag luam hluav taws xob.
Cov kev tswj hluav taws xob ntawm cov hluav taws xob hluav taws xob yog kev hloov kho kom ua rau lub zog ua kom muaj kev hloov pauv ntawm lub zog hluav taws xob hauv kev sib txawv (saib hluav taws xob kev ua haujlwm).Kev hloov kho zaus yog qhov tseem ceeb kom ntseeg tau tias muaj kev sib raug zoo (saib kev hloov pauv tsis yooj yim thiab kev hloov kho sib raug zoo. Thaum lub sijhawm ua haujlwm ib txwm muaj, lub zog phiaj xwm faib khoom xa khoom yuav tsum npaj lub peev xwm kom tsim nyog thiab npaj lub peev xwm ntawm thaub qab. Cov hau kev rau kev tswj cov zaus ntawm lub hwj chim kev cai suav nrog kev pib ua feem ntau, cov zaus tsawg zaus pib, thauj khoom, thiab DC kev tswj hwm. Lub Fais Fab Daim Ntawv yuav tsum tau tsim nyog tau muaj peev xwm ntawm tus kheej muaj peev xwm, thiab tsis siv neeg tsawg zaus ua haujlwm muaj peev xwm ua haujlwm lub zog.
Tsis siv neeg tiam tswj (AGB) yog ib qho kev tswj hwm tsis siv neeg rau zaus thiab lub zog hauv lub zog. Raws li kev ua yeeb yam ntawm kev ua hluav taws xob zoo, AGB tau raws li kev sib tw ntawm cov sijhawm sib npaug los ntawm feeb, uas zwm rau theem ob. Nws txoj haujlwm tseem ceeb suav nrog kev tswj hwm qhov zaus ntawm lub hwj chim sib tshooj nyob rau hauv cov kev ua yuam kev tsis pub dhau, qhov kev hloov kho tsis tau yam tsis muaj kev sib cav; Tswj lub zog Net Hwj Chim ntawm kev sib tshuam hluav taws xob kom ua haujlwm raws li cov neeg tau npaj cov txiaj ntsig; Tswj lub zog pauv hloov hluav taws xob hauv kev sib tshuam hluav taws xob hauv lub zog hauv qhov kev txwv.
Cov kev cai tseem ceeb zaus thiab cov kev cai theem nrab qhov sib txawv los tswj hwm qhov chaw ruaj khov, thiab muaj qhov sib txawv ntawm ob hauv cov lus teb, kev cai lij choj raug cai, thiab cov qauv siv. Electrochemical lub zog cia fais fab koom tes hauv cov kev cai lij choj kev cai tsis tuaj yeem ua rau cov kev coj ua ntawm cov qauv kev ua tau zoo, tab sis kuj ua rau pom qhov tshwj xeeb vim lawv tus cwj pwm.
Qhov sib txawv ntawm thawj zaus zaus zaus kev hloov kho thiab theem nrab zaus
Cov kev tswj hwm theem tseem ceeb yog hais txog qhov kev hloov kho tsis zoo no los kho cov khoom siv ceev thiab ua kom cov khoom siv hluav taws xob nquag thaum muaj zog ntawm lub zog hluav taws xob deviates los ntawm lub hom phiaj zaus. Tus yam ntxwv ntawm cov zaus kev hloov kho yog cov lus teb ceev ceev, tab sis nws tuaj yeem ua tiav kev tswj hwm. Lub hom phiaj tseem ceeb ntawm cov kev cai feem ntau yog los daws cov kev nqus sai Lub Fais Fab Daim Ntawv nyias muaj nyias qhov yuav tsum tau ua rau cov kev cai tseem ceeb ntawm (5} Lub hydroelectric unit ua haujlwm ntawm (5 0 ± 0.05) hz; Qhov chaw nres nkoj photovoltaic ua haujlwm ntawm (50 ± 0.06) HZ; Cov cua fais fab cog kev ua haujlwm ntawm (50 ± 0.10) HZ.
Cov txheej txheem tseem ceeb yog kev teb sai mechanism cia li ua los ntawm cov tshuab hluav taws xob. Thaum cov phiaj xwm zaus cuam tshuam los ntawm cov teeb tsa tus nqi, txhua lub tshuab hluav taws xob tsim tawm sai sai los txo cov amplitude kev hloov pauv. Hom kev cai no yog txhais tau tias nws tsis tuaj yeem tshem tawm ntau qhov kev sib txawv, tab sis tsuas yog txo nws txoj kev hloov pauv. Tus yam ntxwv ntawm cov zaus kev hloov kho yog nws qib siab ntawm sai sai thiab kev siv tshuab, feem ntau ua tiav nrog rau ncua sijhawm (feem ntau tsis pub dhau 10 vib nas this) thiab me me amplime ntau zaus hloov pauv.
Cov kev tswj ntau zaus, tseem hu ua ib tiam tsis siv neeg los ntawm lub tshuab hluav taws xob hloov kho, kom tau raws li qhov yuav tsum tau muaj kev ruaj khov. Kev hloov kho ob zaug zaus thiab siv tau ntau zaus hloov kho thiab saib xyuas thiab kho lub zog ntawm cov kab sib txuas.
Cov kev cai txuas ntxiv yog kev sib tham ntxiv lossis kev ntsuas kev ntsuas ntawm cov kev sib tw ntau zaus, ua kom pom cov phiaj xwm tseem ceeb rau nws cov nqi. Qhov no feem ntau yog ua tiav los ntawm lub chaw xa hluav taws xob muab cov lus qhia rau cov khoom siv hluav taws xob tshwj xeeb raws li kev hloov pauv ntawm zaus, lossis los ntawm kev tswj hwm tiam (AGC). Piv rau thawj zaus zaus cov kev sib cais, cov zaus feem ntau zaus muaj kev sib haum xeeb dua vim tias nws cuam tshuam nrog kev sib txuas lus, thiab kev txiav txim siab, thiab cov txheej txheem txiav txim siab. Thib ob cov kev sib txawv ntawm cov kev sib txawv yog tsuas yog siv los ua cov kev sib txawv nrog cov kev hloov pauv ntau dua nrog loj hloov pauv (}. 5% ~ 1. 10 feeb txog 30 feeb).
Qhov zoo ntawm electrochemical lub zog cia fais fab koom nrog hauv cov kev cai zaus
Kev tswj hwm lub zog yog hais txog kev siv cov kev cai ceev thiab raug cov peev txheej ntawm cov khoom siv hluav taws xob ntawm cov phiaj xwm kev cai lij choj hauv AGC
Cov kev sib koom ua ke zaus cov kev cai ntsuas K {}} kev hloov pauv ntawm chav tswj hwm ntawm chav tsev / 5min, k 3=1- Cov kev hloov kho tsis raug ntawm lub hwj huam ntawm cov khoom siv Raws li cov cai ntawm yav qab teb fais fab rooj sib chaws; K1 muaj qhov siab tshaj plaws ntawm 5, thaum K3 muaj tus nqi siab tshaj plaws ntawm 1. Yog li ntawd, qhov tseem ceeb tshaj plaws yog 3.
Electrochemical Zog cia fais fab nroj tsuag, raws li kev hloov pauv tshiab, tau pom zoo heev hauv kev koom ua ke, feem ntau yog cuam tshuam hauv cov hauv qab no:
Teb Flasad ceev:Electrochemical Zog kaw cov tshuab tuaj yeem ua tiav tus nqi thiab kev hloov mus rau hauv milliseconds, deb tshaj qhov ceev ntawm cov khoom siv hluav taws xob ua kom cua sov. Qhov no txhais tau tias nws tuaj yeem teb cov nrawm dua rau cov kev hloov pauv hauv cov phiaj xwm ntau, muab kev txhawb nqa ntau dua.
Yog Kev Tswj Xyuas Tseeb:Lub zog cia tej lub zog tuaj yeem ua tiav kev tswj hwm muaj zog heev, uas pab txhim kho lub zaus ruaj khov ntawm tag nrho cov zog hluav taws xob. Qhov no yog qhov tshwj xeeb tshaj yog thaum ntsib cov randomness thiab intermittical ntawm kev siv hluav taws xob tshiab.
Kev tiv thaiv ib puag ncig:Piv nrog tsoos fossil roj zog tsis siv cov tsev cog khoom muaj pa roj emissions lossis lwm yam kuab paug, uas ua tau zoo tam sim no rau kev loj hlob lub zog. Lub caij no, vim nws lub zog hloov kho tau zoo, lub zog cia lub tshuab tuaj yeem txo cov nqi kev ua haujlwm rau qee yam. Hauv cov ntsiab lus, cov txheej txheem kev cai tseem ceeb thiab kev ua haujlwm sib txawv, ua haujlwm ua haujlwm tau zoo ntawm cov hluav taws xob sib thooj; Electrochemical lub zog cia fais fab chaw nres tsheb fais fab, muaj qhov tseem ceeb tshaj plaws hauv kev txhawb nqa lub zog ntawm cov kev tsim kho cov grids ntse.
The energy power characteristic refers to the external charging and discharging and energy changes of energy storage batteries viewed from the grid side, and its dynamic model is shown in the following figure. Among them, PESS is the active power, Psset is the initial set power of energy storage, EESS is the rated capacity, η 1 is the discharge efficiency coefficient and η 1>1, η 2 yog them cov coefficiency thiab η 2<1, SOC0 is the initial state of charge of energy storage, SOC is the current state of charge of energy storage, that is, the ratio of current energy to total energy.
Hauv cov ntsiab lus, cov txheej txheem kev cai tseem ceeb thiab kev ua haujlwm sib txawv, ua haujlwm ua haujlwm tau zoo ntawm cov hluav taws xob sib thooj; Electrochemical lub zog cia fais fab chaw nres tsheb fais fab, muaj qhov tseem ceeb tshaj plaws hauv kev txhawb nqa lub zog ntawm cov kev tsim kho cov grids ntse.
