Brazil's Energy Storage Capacity Reserve Auction Prioritizes Weak Grid Areas

 

Brazil's Energy Storage Capacity Reserve Auction Prioritizes Weak Grid Areas, 10% -30% ntawm Nodes Tau Txais Cov Nyiaj Xaiv Qhov Chaw

 

Brazil's Energy Research Office tau tshaj tawm txoj hauv kev xaiv qhov chaw rauroj teeb lub zog cia systemsnyob rau hauv peev reserves auctions. Txoj kev no tsom mus rau cov phiaj xwm yeej los nrhiav cov nodes tsis muaj zog hauv lub teb chaws sib cuam tshuam, yog li kev txhim kho kab sib chaws robustness, txhawb kev ruaj ntseg voltage, thiab muaj peev xwm txhim khu kev qha. Cov ntaub ntawv qhia tshwj xeeb yog tam sim no qhib rau pej xeem tawm tswv yim txog thaum Lub Kaum Ob Hlis 1st, hais txog qhov chaw cov txheej txheem ua ntej cov nodes nrog qis zog hluav taws xob.

 

Txoj kev no siv hluav taws xob muaj zog los ua lub hauv paus rau kev xaiv qhov chaw, txheeb xyuas cov kab ke nrog qhov muaj zog qis tshaj (10%, 20%, lossis 30%) ua ntej -tier qhov tseem ceeb. Cov kev ntsuam xyuas kev ruaj ntseg dynamic yog tom qab ntawd siv los tshuaj ntsuam rau siab - qhov chaw muaj txiaj ntsig ntawm lub zog cia nrog cov hluav taws xob sib sib zog nqus thiab rov qab qeeb dua. Cov kev ntsuam xyuas ua ntej qhia tau hais tias muaj kev sib tshooj siab ntawm cov kev txheeb xyuas ntawm cov nodes thiab cov cheeb tsam uas paub txog qhov teeb meem ntawm kev tswj hluav taws xob, nrog rau cov chaw uas cov neeg ua haujlwm tau txiav txim siab siv cov condensers synchronous.

 

Qhov kawg auction scheme yuav suav nrog tag nrho cov npe ntawm cov chaw tseem ceeb, nrog rau cov haujlwm txuas mus rau cov npe tau txais nyiaj tshwj xeeb. Brazil's Energy Research Office tau hais ntxiv tias txoj kev no tuaj yeem coj daim phiaj -raws lizog cia systemskom stabilize voltage, txhim kho dynamic kev ua tau zoo, thiab txo cov hardware xav tau ntxiv. Nws cia siab tias lub zog cia cov phiaj xwm siv los ntawm txoj kev no yuav txhim kho daim phiaj yooj yim thiab npaj rau kev sib koom ua ke ntawm cov feem ntau ntawm cov hluav taws xob tauj dua tshiab.
