Photovoltaic ntxiv rau lub zog cia, yooj yim tso, yog kev sib txuas ntawm lub hnub ci hluav taws xob tsim thiab roj teeb cia. Raws li photovoltaic daim phiaj-kev sib txuas muaj peev xwm ua tau siab dua thiab siab dua, qhov cuam tshuam ntawm daim phiaj hluav taws xob nce ntxiv, thiab lub zog cia tau ntsib txoj hauv kev loj hlob ntau dua.
Photovoltaics ntxiv rau lub zog cia muaj ntau yam txiaj ntsig. Ua ntej, nws ua kom lub zog ruaj khov thiab txhim khu kev qha. Lub zog cia khoom zoo li lub roj teeb loj uas khaws cov hnub ci ntau dhau. Thaum lub hnub tsis txaus lossis qhov kev thov rau hluav taws xob siab, nws tuaj yeem muab lub zog los xyuas kom muaj lub zog txuas ntxiv.
Qhov thib ob, photovoltaics ntxiv rau lub zog cia tuaj yeem ua rau lub hnub ci hluav taws xob ntau dua kev lag luam. Los ntawm kev ua kom zoo dua qub, nws tuaj yeem tso cai rau siv hluav taws xob ntau dua los ntawm nws tus kheej thiab txo tus nqi ntawm kev yuav khoom hluav taws xob. Tsis tas li ntawd, cov cuab yeej siv hluav taws xob kuj tseem tuaj yeem koom nrog hauv lub khw muag khoom siv hluav taws xob kom coj tau cov txiaj ntsig ntxiv. Daim ntawv thov ntawm lub zog cia tshuab ua rau lub hnub ci zog tsim tau yooj yim dua thiab tuaj yeem ua tau raws li ntau yam kev xav tau ntawm lub zog. Nyob rau tib lub sijhawm, nws tseem tuaj yeem ua haujlwm nrog cov chaw tsim hluav taws xob virtual kom ua tiav qhov kev sib txuas ntawm ntau lub zog thiab kev sib koom tes ntawm cov khoom siv thiab kev thov.
Lub zog txuag hluav taws xob photovoltaic yog qhov sib txawv ntawm cov hluav taws xob hluav taws xob sib txuas. Lub zog cia cov roj teeb thiab cov roj teeb them thiab cov khoom tso tawm yuav tsum tau ntxiv. Txawm hais tias tus nqi them ua ntej yuav nce mus rau ib qho twg, daim ntawv thov ntau dua. Hauv qab no peb qhia txog plaub lub photovoltaic + lub zog cia daim ntawv thov scenarios raws li kev siv sib txawv: photovoltaic off-grid zog cia daim ntawv thov scenarios, photovoltaic off-grid zog cia daim ntawv thov scenarios, photovoltaic grid-txuas lub zog cia daim ntawv thov scenarios thiab microgrid zog cia system daim ntaub ntawv. Scenes.
01
Photovoltaic off-grid zog cia daim ntawv thov scenarios
Photovoltaic off-grid lub zog cia lub zog tsim hluav taws xob tuaj yeem ua haujlwm ntawm nws tus kheej yam tsis muaj kev cia siab rau daim phiaj hluav taws xob. Lawv feem ntau siv nyob rau hauv tej thaj chaw deb roob, thaj chaw tsis muaj zog, Islands tuaj, chaw nres tsheb sib txuas lus, txoj kev teeb thiab lwm qhov chaw thov. Lub kaw lus muaj xws li photovoltaic array, photovoltaic inverter integrated tshuab, roj teeb pob, thiab hluav taws xob load. Lub photovoltaic array hloov lub hnub ci zog rau hauv lub zog hluav taws xob thaum muaj teeb pom kev zoo, muab lub zog rau kev thauj khoom los ntawm lub tshuab inverter tswj, thiab them cov roj teeb rau tib lub sijhawm; Thaum tsis muaj lub teeb, lub roj teeb muab lub zog rau AC load los ntawm inverter.

Raws li qhov tshwm sim ntawm daim ntawv thov lub zog huv si, photovoltaic daim phiaj sib txuas nrog lub zog khaws cia tau nyiam ntau yam hauv kuv lub teb chaws lub zog tshiab kev lag luam. Lub kaw lus sib txuas ua ke photovoltaic lub zog tsim hluav taws xob, lub zog cia khoom siv thiab AC daim phiaj hluav taws xob kom ua tiav kev siv lub zog huv. Cov txiaj ntsig tseem ceeb yog raws li hauv qab no: 1. Txhim kho qhov kev siv hluav taws xob photovoltaic. Kev tsim hluav taws xob photovoltaic muaj kev cuam tshuam zoo heev los ntawm huab cua thiab thaj chaw, thiab muaj kev hloov pauv ntawm lub zog tsim hluav taws xob. Los ntawm cov khoom siv hluav taws xob cia, cov khoom siv hluav taws xob tsim hluav taws xob photovoltaic tuaj yeem ua kom du thiab qhov cuam tshuam ntawm kev tsim hluav taws xob hloov pauv ntawm daim phiaj hluav taws xob tuaj yeem txo qis. Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob khaws cia tuaj yeem muab lub zog rau daim phiaj nyob rau hauv cov teeb pom kev tsis zoo thiab txhim kho kev siv hluav taws xob photovoltaic. 2. Txhim khu kev ruaj ntseg ntawm daim phiaj fais fab. Lub photovoltaic daim phiaj-txuas lub zog cia qhov system tuaj yeem paub txog lub sijhawm saib xyuas thiab kev hloov kho ntawm daim phiaj hluav taws xob thiab txhim kho kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob. Thaum daim phiaj hluav taws xob hloov pauv, lub zog cia khoom tuaj yeem teb sai sai los muab lossis nqus lub zog ntau dhau los ua kom muaj kev ua haujlwm zoo ntawm daim phiaj hluav taws xob. 3. Txhawb nqa kev siv hluav taws xob tshiab Nrog kev txhim kho sai ntawm cov khoom siv hluav taws xob tshiab xws li photovoltaics thiab cua zog, cov teeb meem kev noj haus tau dhau los ua qhov tseem ceeb. Lub photovoltaic daim phiaj-txuas lub zog cia qhov system tuaj yeem txhim kho kev nkag mus tau thiab kev siv qib ntawm lub zog tshiab thiab txo qhov siab ntawm kev tswj hwm ntawm daim phiaj hluav taws xob. Los ntawm kev xa tawm ntawm lub zog cia khoom siv, cov khoom siv du ntawm lub zog tshiab tuaj yeem ua tiav.

Microgrid zog cia system daim ntawv thov scenarios
Raws li ib qho tseem ceeb ntawm lub zog cia khoom, microgrid zog cia qhov system plays lub luag haujlwm tseem ceeb hauv kuv lub teb chaws txoj kev txhim kho lub zog tshiab thiab lub zog. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nrov ntawm lub zog tauj dua tshiab, daim ntawv thov scenarios ntawm microgrid zog cia tshuab txuas ntxiv nthuav dav, feem ntau suav nrog ob yam hauv qab no:
1. Kev faib hluav taws xob tsim hluav taws xob thiab lub zog khaws cia: Kev tsim hluav taws xob xa tawm yog hais txog kev tsim cov khoom siv hluav taws xob me me nyob ze ntawm cov neeg siv, xws li hnub ci photovoltaic, cua zog, thiab lwm yam, thiab cov khoom siv hluav taws xob ntau dhau yog khaws cia los ntawm lub zog cia. yog li ntawd nws tuaj yeem siv tau thaum lub sij hawm lub zog siab tshaj plaws los yog Muab lub zog thaum lub sij hawm ua tsis tiav.
2. Microgrid thaub qab fais fab mov: Nyob rau hauv tej thaj chaw deb, Islands tuaj thiab lwm qhov chaw uas lub hwj chim daim phiaj nkag tau yooj yim, lub microgrid zog cia system yuav siv tau raws li ib tug thaub qab fais fab mov los muab kev ruaj ntseg fais fab mov rau hauv cheeb tsam.
Microgrids tuaj yeem siv tag nrho thiab zoo siv lub peev xwm ntawm cov khoom siv huv huv los ntawm ntau lub zog ntxiv, txo cov yam tsis zoo xws li lub peev xwm me me, lub zog tsis ruaj khov, thiab tsis muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob ywj pheej, ua kom muaj kev nyab xeeb ntawm daim phiaj hluav taws xob, thiab yog ib qho khoom siv hluav taws xob. muaj txiaj ntsig ntxiv rau cov kab hluav taws xob loj. Microgrid daim ntawv thov scenarios yog hloov tau yooj yim dua, qhov ntsuas muaj peev xwm nyob ntawm ntau txhiab watts mus rau kaum tawm megawatts, thiab daim ntawv thov ntau dua.
Daim duab 4 Schematic daim duab ntawm photovoltaic microgrid zog cia system
Daim ntawv thov scenarios ntawm photovoltaic zog cia yog nplua nuj thiab ntau haiv neeg, npog ntau yam ntaub ntawv xws li off-grid, grid-txuas thiab micro-grid. Hauv kev siv cov tswv yim, ntau yam xwm txheej muaj lawv tus kheej qhov zoo thiab cov yam ntxwv, muab cov neeg siv nrog kev ruaj khov thiab muaj zog huv. Nrog rau kev txhim kho txuas ntxiv thiab txo tus nqi ntawm photovoltaic technology, photovoltaic zog cia yuav ua lub luag haujlwm tseem ceeb hauv lub zog yav tom ntej. Nyob rau tib lub sijhawm, kev nce qib thiab kev siv ntau yam xwm txheej tseem yuav pab txoj kev loj hlob sai ntawm kuv lub teb chaws lub zog tshiab kev lag luam thiab pab txhawb kom muaj kev hloov pauv ntawm lub zog thiab kev loj hlob ntsuab thiab qis-carbon.
