Kev sib koom tes ntawm Berkeley Lab thiab USGS tsim cov ncauj lus kom ntxaws thiab nthuav dav tshaj plaws rau pej xeem muaj ntau lub hnub ci chaw khaws ntaub ntawv rau hnub tim.
Berkeley Lab, koom tes nrog US Geological Survey (USGS), tso tawm Tebchaws Meskas Loj-Scale Hnub Ci Photovoltaic Database (USPVDB) (txuas yog sab nraud) hnub no. USPVDB yog cov ncauj lus kom ntxaws thiab cov ntaub ntawv nthuav dav ntawm av-mounted loj-teev hnub ci (LSS) photovoltaic zog qhov chaw thiab lawv cov cwj pwm hauv Tebchaws Meskas. Cov ntaub ntawv tuaj yeem rub tawm hauv ntau hom, nkag tau los ntawm tus saib hauv online, thiab yuav hloov kho txhua xyoo.
Nyob rau hauv kaum xyoo dhau los, LSS txoj kev loj hlob tau nce ntau nyob rau hauv cov nqe lus ntawm ob qho tib si tsim hluav taws xob muaj peev xwm thiab tus naj npawb ntawm cov chaw tshiab tuaj online txhua xyoo. USPVDB muab txoj hauv kev los txheeb xyuas cov xwm txheej keeb kwm hauv LSS thiab txhawm rau txheeb xyuas qhov tseeb ntawm cov nqi thiab cov txiaj ntsig ntawm kev txhim kho yav tom ntej, thaum tseem muab kev nkag tau yooj yim tsis tau pom dua rau txhua tus xav paub txog LSS qhov kev tsim tawm tsis ntev los no.
Ib tsab xov xwm luam tawm hauv Nature Scientific Data (txuas yog sab nraud) piav qhia txog USPVDB thiab nws txoj kev txhim kho. Cov kws sau ntawv yuav tuav lub rooj sib tham hauv webinar npog USPVDB thaum Lub Kaum Ib Hlis 16 thaum 1 teev tsaus ntuj Eastern / 10 AM Pacific. Sau npe rau lub webinar ntawm no: https://lbnl.zoom.us/webinar/register/WN_DABtH_86SNe4TSZPKn_QPg(link is external).
USPVDB muab cov ntaub ntawv zoo uas tsis tau muaj dua los ntawm qhov chaw thiab tus cwj pwm rau ze li LSS cov chaw thoob plaws Tebchaws Meskas.
Cov ntaub ntawv muaj xws li 3,699 LSS hauv av-mounted chaw uas muaj peev xwm ntau dua 1 MWdc uahauv kev ua haujlwm thoob plaws 47 lub xeev thiab Washington, DC txog thaum kawg ntawm 2021 (Daim duab 1). Cov ntaub ntawv muaj ob qho tib si geospatial polygons puag ncig cov khoom siv xws li panels thiab inverters. Cov polygons tau kos tes siv cov duab siab dav dav. Qhov no yog qhov kev txhim kho tseem ceeb ntawm lwm cov ntaub ntawv, suav nrog Lub Chaw Haujlwm Saib Xyuas Lub Zog (EIA), uas tsuas yog muaj kev sib koom ua ke ntawm lub hauv paus ntsiab lus ntawm lub hnub ci loj loj, uas tsis yog tus kheej txheeb xyuas qhov tseeb.
Cov ntaub ntawv USPVDB suav nrog cov ntsiab lus nthuav dav, suav nrog qhov loj ntawm thaj chaw array, vaj huam sib luag hom tshuab, hom axis, xyoo ntawm kev teeb tsa, thiab ntsuas lub peev xwm los tsim hluav taws xob. Tsis tas li ntawd, USPVDB coj ntau yam cwj pwm ua ke, xws li yog qhov chaw nyob tam sim no lossis yav dhau los ib puag ncig muaj kab mob thiab yog tias lub chaw muaj cov yam ntxwv ntawm kev ua liaj ua teb. Pab neeg sib koom ua ke los ntawm Environmental Protection Agency's RE-Powering (txuas yog sab nraud) cov ntaub ntawv thiab National Renewable Energy Laboratory's InSPIRE(txuas yog sab nraud) agrivoltaics cov ntaub ntawv. Qhov no tau tso cai rau USPVDB, raws li, muab kev piav qhia ntawm cov chaw chaw, xws li greenfield lossis yav dhau los, tam sim no, lossis xav tias muaj kab mob sib kis, nrog rau txheeb xyuas cov chaw ua liaj ua teb uas muaj kev pabcuam ua liaj ua teb lossis ib puag ncig ntawm pawg vaj huam sib luag lossis ib puag ncig arrays.
Daim duab 1. Qhov chaw ntawm USPVDB cov chaw
USPVDB tau tsim los ntawm kev ua tib zoo saib xyuas qhov pom thiab kev lees paub zoo.
USPVDB txoj kev txhim kho tau ua tiav thoob plaws plaub theem pib ntxiv kom ntxaws thiab pom hauv daim duab 2:
Theem 1 - Georectifying PV chaw tswj xyuas:Pib los ntawm qhov chaw latitude thiab longitude suav nrog hauv EIA cov ntaub ntawv, 10 qhov chaw ntawm LSS cov chaw tau pom pom tseeb siv cov duab huab cua siab.
Theem 2 - Digitizing LSPV array polygons:Siv cov georectified PV chaw tswj xyuas, polygons tau kos manually nyob ib ncig ntawm lub vaj huam sib luag arrays thiab inverters los ntawm USGS thiab LBNL cov kws tshuaj ntsuam siv ArcGIS software.
Theem 3 - Kev pov hwm zoo thiab kev tswj xyuas qhov zoo (QA/QC) kev daws teeb meem, thiab kev tshawb nrhiav qhov tob: Ntau cov txheej txheem QA / QC tau ua haujlwm los xyuas kom meej qhov ua tau zoo tshaj plaws ntawm qhov raug. Qhov no suav nrog kev siv cov kws tshuaj ntsuam xyuas sib txawv los tshuaj xyuas kev ua haujlwm, sib piv USPVDB rau ob peb lwm cov ntaub ntawv ntawm US LSS, thiab khiav cov kev ntsuam xyuas txheeb xyuas kom pom cov txiaj ntsig.
Theem 4 - Populating facility attributes:Cov ntaub ntawv ntxiv tau ntxiv rau txhua qhov chaw, kos duab ntawm EIA thiab ntau qhov chaw cov ntaub ntawv.
Daim duab 2. USPVDB txoj kev txhim kho
USPVDB cov ntaub ntawv tau tshaj tawm rau pej xeem siv rau hauv kev tshawb fawb, kev tshuaj xyuas txoj cai, kev txiav txim siab, thiab kev tshawb fawb dav dav.
USPVDB thiab nws cov ntaub ntawv saib xyuas cuam tshuam yuav raug siv los ntawm tsoomfwv cov koomhaum, cov kws tshawb fawb, cov tuam txhab ntiag tug, thiab lwm tus neeg muaj feem cuam tshuam rau ntau yam kev tshuaj xyuas uas yav dhau los tsis tuaj yeem ua tiav. Tsis tas li ntawd, qhov yooj yim ntawm kev nkag mus rau cov ntaub ntawv yuav qhib lub sijhawm tshiab rau ntau tus neeg koom nrog los kawm thiab cuam tshuam nrog cov qauv hauv LSS xa tawm thoob plaws Asmeskas USPVDB muaj nyob rau hauv geospatial (shapefile, GeoJSON) thiab tabular (csv) versions, thiab tuaj yeem rub tawm raws li tag nrho cov ntaub ntawv lossis hauv ntu ntawm daim ntawv thov raws tu qauv interface (API). Tsis tas li ntawd, tus neeg saib xyuas lub vev xaib sib tham ua rau muaj ntau lub sijhawm tshwj xeeb rau kev tshawb nrhiav cov ntaub ntawv thiab kev pom, xws li kev xa tawm mus rau lub sijhawm thiab los ntawm qhov ntau thiab tsawg.
