Cov yam ntxwv cuam tshuam rau kev tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag

Sep 11, 2024 Tso lus

  Raws li lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob tauj dua tshiab, Photovoltaic Power Plants (PVPPs) muab cov khoom siv rau kev siv fossil fuels. Kev ua tau zoo thiab muaj peev xwm tsim tau ntawm PVPPs raug cuam tshuam los ntawm ntau yam ib puag ncig, kev ua haujlwm thiab kev ua haujlwm. Kev txheeb xyuas cov kev hloov pauv no yog qhov tseem ceeb txhawm rau txhawm rau txhim kho cov txiaj ntsig ntawm cov nroj tsuag thiab lub zog tso zis. Lub hom phiaj ntawm tsab xov xwm no yog los piav qhia meej txog qhov kev koom tes tseem ceeb no rau PV tsim hluav taws xob raws li muaj pov thawj tshawb fawb, nrog rau cov ntaub ntawv coj los ntawm thaj chaw.

1. Solar Irradiance thiab Geographic qhov chaw

 

Tus thawj tsav tsheb ntawm PV lub zog tso zis yog lub hnub ci irradiance los yog hnub ci uas ncav cuag PVPP. Qhov chaw ntawm PVPP txiav txim siab qhov ntev thiab siv ntawm cov hnub ci hluav taws xob uas nws tau txais. Sahara-zoo li thaj chaw kuj muaj lub hnub ci zoo tshaj plaws vim tias lawv muaj huab cua qis thiab muaj lub hnub ci ntev dua thiab tsis muaj kev cuam tshuam (xws li Saharan suab puam). Ib rooj plaub ntawm taw tes yog Qinghai-Tibet Plateau. Nws muaj hnub ci hluav taws xob hluav taws xob ntawm qhov kev txiav txim ntawm 30MJ / m2. Txawm li cas los xij, nws muaj qhov kub thiab txias heev, uas cuam tshuam rau kev ua haujlwm ntawm lub hnub ci vaj huam sib luag. Lub caij sib txawv kuj ua rau lub hnub ci sib txawv. Muaj lub ncov hnub ci irradiance nyob rau lub caij ntuj sov.

Txawm li cas los xij, nyob rau lub caij ntuj no, nws txo qis vim tias tsis muaj hnub ci thiab lub hnub rays nyob rau ntawm kaum sab xis. Cov peev txheej tau diverged los ntawm cheeb tsam. Muaj kev loj hlob ntawm cov khoom siv hnub ci dhau sij hawm nyob rau hauv cheeb tsam ntug dej hiav txwv thiab tus dej Yangtze. Plateau muaj cov khoom siv hnub ci poob qis. Qhov no yog qhov chaw hnub ci tshaj plaws Tuam Tshoj muaj, thiab teeb liab yog qhov sib txawv ntawm hnub ci kev pab cuam los ntawm cheeb tsam.

 

2. Photovoltaic Module Efficiency

 

Covefficiency ntawm solar cellsncaj qha cuam tshuam lub zog hloov dua siab tshiab. Monocrystalline silicon panels, nrog kev ua tau zoo tshaj 22%, yog siv dav, tab sis cov thev naus laus zis tshiab xws li perovskite thiab bifacial hlwb cog lus tias yuav muaj ntau dua. Piv txwv li, Jinko Solar's N- hom ABC modules ua tiav 25.3% kev ua haujlwm zoo, ua haujlwm zoo dua qub PERC vaj huam sib luag los ntawm 1.15–3.96% hauv ntau hom.

Qhov kub thiab txias yog qhov kev tawm tsam tseem ceeb. Silicon hlwb poob kev ua haujlwm thaum kub nce -txhua 1℃nce siab tshaj 25℃txo cov zis los ntawm 0.04%. Kev ua cua sov ntuj, mounting systems nrog cov cua txias, lossis txawm tias dej -cov vaj huam sib luag txias tuaj yeem txo cov nyhuv no.

 

3. Ib puag ncig thiab kev ua haujlwm nyuaj

 

Plua plav thiab paug:
Cov ntoo, cov tsev, thiab lwm yam kev cuam tshuam ib feem ntawm lub hnub ci vaj huam sib luag thiab cuam tshuam qhov ntws ntawm cov tam sim no hauv cov vaj huam sib luag sib txuas, uas ua rau cov txiaj ntsig tseem ceeb. Bifacial panels thiab smart tracking systems tuaj yeem cuam tshuam qhov no los ntawm kev ntes cov teeb pom kev zoo.

Huab cua Extremes: Hail, daus, thiab cua daj cua dub ua rau cov vaj huam sib luag puas, thaum overirradiance (xws li, nyob rau hauv cov suab puam cheeb tsam) muaj kev pheej hmoo overheating. Cov ntaub ntawv zoo tshaj plaws xws li tiv thaiv-corrosion steel thav duab thiab tus kheej- ntxuav txheej txhim khu kev ruaj ntseg.

 

4. Technical thiab System Design Factors

 

Inverter Efficiency: Inverters convert DC electricity to AC electricity. The inverter's efficiency typically ranges from 95% to 98%, based on the MPPT algorithm. Fluctuating conditions of the MPPT calibration add up to a 2% to 5% reduction in inverter output. DC/AC Ratio: A (higher) DC/AC ratio (>1.2) tso cai rau kev khaws cia lossis txo qis ntawm cov khoom siv hluav taws xob DC, ua kom muaj kev saib xyuas ntawm daim phiaj ruaj khov. Cov neeg uas xaiv kom loj dua lawv cov inverters yuav raug nqi ntxiv. Cabling thiab Losses: Losses tshwm sim ntawm DC thiab AC xov hlau (3% thiab 1-2%, feem) tsim qhov kev xav tau rau kev ua kom zoo dua ntawm cov cables nrog rau qhov tsawg kawg nkaus kom thauj hluav taws xob. High voltage DC yog siv los txo qhov kev puas tsuaj uas tshwm sim thaum kis hluav taws xob.

 

5. Site-Kev ua kom zoo tshwj xeeb

 

Tilt thiab Orientation: Kev taw qhia ntawm cov qauv (cov vaj huam sib luag) mus rau lub hnub txoj kev, piv txwv li, nyob rau sab qaum teb Hemisphere, yog sab qab teb -fab, nrog lub kaum sab xis uas sib haum nrog lub latitude. Cov neeg taug qab uas tuaj yeem kho tau thiab taug qab hauv qhov kev coj ua kom zoo tuaj yeem ua kom tag nrho lub zog sau los ntawm ib qho array los ntawm 20% mus rau 30%. Cov trackers adjustable no yuav tsum tau ntxiv mechanical complexity. Kev Siv av thiab Topography: Sloped struts yuav xav tau terracing los yog ballast systems kom tshem tawm shading ntawm modules. Qhov siab mounts yog qhov zoo rau kev teeb tsa suab puam kom txo tau qhov tshwm sim ntawm cov modules tau npog los ntawm xuab zeb. Grid Integration: Qhov ze dua lub hnub ci PV installation yog rau lub chaw nres tsheb, qhov qis dua qhov kev sib kis yuav raug tshwm sim hauv kev thauj khoom uas tsim hluav taws xob. Kev siv cov cuab yeej ntse ntse uas tau tsav los ntawm kev txawj ntse txawj ntse (AI) uas kwv yees / faib kev thov pab txhim kho kev tswj hwm kev sib tshuam ntawm PV tsim hluav taws xob.

 

6. Kev tsim kho tshiab tshiab

 

Bifacial Panels: Kev siv cov vaj huam sib luag bifacial tuaj yeem ua rau nce ntawm 10-20% tawm los ntawm lub hnub ci arrays vim yog lub teeb pom kev tawm hauv av, qhov no yog qhov tseeb tshwj xeeb hauv qhov chaw daus thiab xuab zeb.
AI thiab Predictive Analytics: Artificial Intelligence thiab Predictive Analytics muab cov tshuab kev kawm nrog tiag - cov ntaub ntawv sijhawm los kwv yees cov khoom tsim los ntawm cov ntaub ntawv huab cua thiab tso cai rau cov neeg saib xyuas kab sib chaws ua kom zoo dua kab sib chaws ua ntej muaj teeb meem. Piv txwv li, Tuam Tshoj lub Gobi Desert nroj tsuag siv AI los kho cov haujlwm ua ntej ntawm cov xuab zeb.

Hybrid Systems: Pairing PV nrog cua turbines lossis roj teeb ua kom muaj kev sib raug zoo thaum lub sij hawm qis - hnub ci.

Txhawm rau txhim kho tus nqi ntawm photovoltaic (PV) lub zog tsim los ntawm lub hnub ci, kev txhim kho cov tswv yim zoo yog qhov tseem ceeb los muab cov tswv yim zoo rau kev tsim cov thev naus laus zis los tswj thiab siv cov tshuab photovoltaic (PV). Txawm hais tias hmoov av los ntawm ib puag ncig yog ib qho kev sib tw tseem ceeb thiab qhov kub thiab txias tseem ua rau muaj kev cuam tshuam tsis zoo rau photovoltaic (PV) kev ua haujlwm, cov ntaub ntawv thiab cov qauv siv hauv photovoltaic (PV) raug txhim kho zoo; Yog li, kev ua tau zoo ntawm ntau dua 30 feem pua ​​​​ua tiav nrog kev tsim cov khoom siv tshiab, cov tshuab tshiab, thiab kev nqis peev ntau ntxiv hauv cov tshuab ntse. Kev ua tau zoo ntawm cov dej num no yuav yog qhov tseem ceeb rau kev tsim kom muaj lub hnub ci zog. Tam sim no, ntau lub teb chaws tab tom txav nrawm los tshem tawm cov pa roj carbon monoxide kom dhau los ua cov pa roj carbon- haiv neeg nruab nrab.
