Intermittency of Solar Power thiab Stability Challenges
Thaum Lub Plaub Hlis 28, 2025, hluav taws xob loj tau tshwm sim hauv Spain thiab Portugal. Qhov xwm txheej tau tshwm sim los ntawm qhov hluav taws xob hluav taws xob thaum sawv ntxov. Spain cov phiaj xwm hluav taws xob ua tsis tiav los nqus qhov nce siab zoo vim kev npaj tsis txaus thiab ntsuas kev teb. Qee lub tuam txhab hluav taws xob kaw ua ntej ntxov, ua rau qhov xwm txheej hnyav dua. Hauv vib nas this, cov khoom siv hluav taws xob poob li ntawm 60%, ua rau muaj kev cuam tshuam loj heev. Qhov hluav taws xob tau ua rau kev thauj mus los tuag tes tuag taw thiab kev sib txuas lus tawg.
Intermittency of Solar Power thiab Stability Challenges
Spain muaj feem ntau ntawm lub hnub ci tsim hluav taws xob hauv nws lub zog sib xyaw. Nyob rau hnub tsaus ntuj, cov khoom siv hluav taws xob hnub ci tau poob qis hauv ob peb feeb xwb, los ntawm ntau dua 18 gigawatts mus rau tsuas yog 8 gigawatts. Qhov sib cuam tshuam ntawm lub zog qhov chaw no ua rau muaj kev hloov pauv loj hauv cov zis hluav taws xob, uas ua rau muaj teeb meem loj heev rau daim phiaj zaus thiab qhov voltage stability.
Ntxiv mus, tsawg dua 30% ntawm Spain lub zog tshiab zog ua tau raws li cov qauv, thiab qis -voltage caij- los ntawm kev ua haujlwm tsis tau dav ntsia hauv photovoltaic thiab cua fais fab units. Cov chav no muaj kev nkag siab zoo rau kev hloov pauv ntawm kab sib chaws, thiab txawm tias me me voltage oscillations tuaj yeem ua rau muaj kev tiv thaiv kaw.
Tsis txaus Grid Infrastructure Exacerbates Stability Teeb meem
Spain cov phiaj xwm phiaj xwm kuj tau ua lub luag haujlwm hauv qhov teeb meem kev ruaj ntseg. Lub teb chaws muaj peev xwm cia lub zog tsawg, tsuas yog 2.1 gigawatt- teev muaj, uas tsis txaus los cuam tshuam qhov cuam tshuam ntawm lub zog hluav taws xob tsis zoo los ntawm cov khoom siv txuas ntxiv.
Tsis tas li ntawd, daim phiaj yog kev laus thiab tsis muaj kev sib tshuam txaus. Kwv yees li 40% ntawm cov khoom siv hluav taws xob sib kis tau ua haujlwm rau ntau tshaj 30 xyoo, thiab cov nodes tseem ceeb yog feem ntau ua rau overloading thiab melting nyob rau hauv huab cua load.
Thaum lub sijhawm hluav taws xob hluav taws xob, nws tau tshaj tawm tias Spain lub phiaj xwm tsis muaj peev xwm tswj tau qhov hluav taws xob tsis txaus. Cov kev npaj thiab kev ntsuas kev teb tau pom tias tsis txaus, ua tsis tiav qhov nqus hluav taws xob hauv lub sijhawm thiab ua rau muaj kev cuam tshuam ntawm cov saw hlau tsis sib haum.
Cov Lus Qhia Kawm thiab Kev Ntsuas Yuav Tau Ua
Cov hluav taws xob hluav taws xob hauv Spain ua haujlwm ua ib qho tseem ceeb ceeb toom ntawm qhov cuam tshuam ntawm kev sib koom ua ke ntawm hnub ci thiab lwm yam khoom siv hluav taws xob txuas ntxiv rau ntawm daim phiaj kev ruaj ntseg. Tsiv mus rau pem hauv ntej, nws yog ib qho tseem ceeb kom ceev txoj kev loj hlob thiab kev siv lub zog cia technologies los txhim kho cov kab sib chaws lub peev xwm los cuam tshuam qhov kev hloov pauv hauv kev tsim hluav taws xob tauj dua tshiab. Kev txhim kho cov phiaj xwm phiaj xwm phiaj xwm thiab txhim kho nws qib kev txawj ntse kuj tseem ceeb rau ntxiv dag zog rau kev tswj hluav taws xob muaj peev xwm.
Tsis tas li ntawd, yuav tsum tau tsim kom muaj kev npaj txhij txog hluav taws xob thiab cov phiaj xwm daws teeb meem thaum muaj xwm txheej ceev. Kev faib cov neeg ua haujlwm kom meej, txhim kho kev sib koom tes, thiab ua kom pom tseeb yog qhov tsim nyog los xyuas kom meej cov lus teb zoo rau cov xwm txheej tsis tau xav txog thiab tswj xyuas kev ua haujlwm ruaj khov.
