Abacwaningi abavela eNyuvesi yaseNtshonalanga yaseCanada basungule umthombo ovulekile, i-blockchain-based utility virtual for peer-to-peer (P2P) yokuhweba ngelanga, besebenzisa izinkontileka ezihlakaniphile ukonga kufika ku-$1,600 (amadola ase-US) ezindlini ezingu-10 ezimweni ezilingisayo.

Ososayensi abavela eNyuvesi YaseNtshonalanga YaseCanada baklame insiza ebonakalayo evulekile enomthombo ovulekile yokuqapha abasebenzisi be-PV futhi inike amandla ukuhweba kwe-P2P. Uhlelo lwabo olusekelwe kubuchwepheshe be-SolarXchange blockchain ludala izinkontileka ezihlakaniphile ngokwalo, lula ukuthengiselana phakathi kwabasebenzisi ngehora. "Sikuthakasela ngempela ukusebenza nezinsiza zikagesi ezigxile phambili ezifuna ukunika amandla isizukulwane esatshalaliswa kakhulu solar kanye nokushintshaniswa kwe-P2P ukwenza igridi kagesi eqinile ngempela," kusho umbhali ohambelana noDkt. Joshua M. Pearce etshela pv umagazini.
“Ezinsizakalweni ezikhetha ukwamukela isizukulwane esisabalalisiwe kunezinhlobo ezahlukene zebhizinisi. Enye indlela ethokozisayo ukwenza ukuthi iP2P ihwebe ngogesi welanga,” kusho izifundiswa. “Inkinga eyinhloko ukuthi izinhlelo zokukhokhisa sezisungulelwe ukukhiqizwa kukagesi endaweni eyodwa, kudingeka indlela entsha yokukhokhisa/ukuhweba eyenzelwe ukuphehla ugesi. Enye indlela ukusebenzisa ubuchwepheshe be-blockchain ngoba ivumela ukuthengiselana okuphephile. ”
I-virtual utility inoveli isekelwe emazingeni amabili ezinkontileka, abhalwe kusetshenziswa i-Solidity, olunye lwezilimi zenkontileka ehlakaniphile ezidumile. Kumongo we-blockchain, izinkontileka ezihlakaniphile amakhodi enza imisebenzi ngokuzenzakalelayo lapho izimo ezithile zifinyelelwa. Ezingeni lokuqala, indlu ngayinye ebambe iqhaza inenkontileka ye-House, echaza isimo esijwayelekile sokukhiqizwa kwe-PV yomsebenzisi kanye nesidingo. Ezingeni lesibili, insiza ebonakalayo iqhuba inkontileka ye-HouseFactory, edonsa ulwazi oluvela ezinkontilekeni zezinga lokuqala, ilandelela izidingo nokukhiqizwa kwendlu ngayinye futhi inquma ukuthi ugesi kufanele ushintshwe nini.
“Ukuhlolwa kweyunithi yendlela ngayinye yezinkontileka kubhalwa nge-Solidity, futhi idatha ngokusetshenziswa kwegesi nezindleko iyaqoqwa. Kufanele kuqashelwe ukuthi 'igesi' endabeni yamanethiwekhi e-P2P isho iyunithi yokulinganisa yezindleko zokuthengiselana kanye nezindleko zekhompiyutha hhayi igesi yemvelo," kusho iqembu. "Izindleko eziphelele zokuphakela izinkontileka zibalwe ngokuthuthela izinkontileka ku-Truffle blockchain yasendaweni kanye nokuthola ukusetshenziswa kwegesi nolwazi lwezindleko oluvela ekuphumeni kwetheminali."

Ngemva kokuhlolwa kwemisebenzi ye-blockchain, kwakhiwa ukulingisa kwe-JavaScript ukuze kusetshenziswe izinkontileka kumthwalo wangempela kanye nedatha yokukhiqiza i-PV unyaka owodwa ngehora. Ukulingisa kucubungula izimo ezimbili: zombili zihlanganisa amakhaya ayi-10 kanye nolwazi lwangempela lukagesi oluvela eNew York City. Ucwaningo lwecala lokuqala, "Oontanga Beqiniso," lumelela uhlelo oluvuthiwe esikhathini esizayo lapho zonke izindlu zingama-prosumers ane-PV yazo.
“I-case study yesibili ibizwa nge-Intermittent Transition. Kulolu cwaningo kunezinhlobo ezine zezindlu,” kuchaza ososayensi. “Okokuqala, ingxenye eyodwa kwezine yezindlu ine-PV ephindwe kabili eyidingayo ukuze izisebenzisele yona, imele imizi enezindawo ezinkulu zophahla ezingafakwanga umthunzi. Okwesibili, ikota eyodwa ine-PV eyanele ukufanisa umthamo wabo kagesi minyaka yonke, okungamela indlela iningi lamasistimu e-PV ophahleni aklanywe ngayo namuhla ukusizakala ngamanani we-net metering. Okwesithathu, ingxenye eyodwa kwezine yezindlu inengxenye ye-PV kuphela edingekayo ukuze ihambisane nomthwalo wabo, ongamela izindlu endaweni encane noma engafanelekile. Okokugcina, ingxenye eyodwa kwezine ayinayo i-PV emele amakhaya ngaphandle kwendawo engaphezulu ye-PV ngenxa ye-shading noma amakhaya angenayo imali yokufaka i-PV. "
Ucwaningo lwecala le-True Peers luholele ku-521 kWh wokushintshana kwamandla, okuletha ukonga kwezindleko zonyaka okungu-$70.78 ngaphansi kwesikhathi sokusebenzisa (i-ToU) yesakhiwo sesilinganiso. Ngokuphambene, ucwaningo lwecala le-Intermittent Transition luholele ku-11,478 kWh wokushintshana, nokongiwa kwengqikithi engu-$1,599.24 ngaphansi kwesakhiwo sesilinganiso se-ToU esifanayo.
"Ukuba nokuhlukahluka okukhulu ekukhiqizeni kwe-PV ngaleyo ndlela kubangele ukwanda okungaphezu kwesici esingamashumi amabili ekuhwebeni nasekulondolozeni izindleko eziphelele," kusho abacwaningi.
"Lolu cwaningo luhlose ukukhombisa ukuthi kungenzeka ukudala i-P2P ye-virtual metering system yegesi esebenza kahle eyisondlo esincane kubasebenzisi ngenkathi isalondoloza imali yabasebenzisi," kuphetha leli qembu. “Ngenxa yalokho, lolu hlelo lwenza ukuba ubunikazi be-PV nokubamba iqhaza kunethiwekhi ye-P2P kufinyeleleke kalula. Bobabili abanikazi be-PV nabanikazi abangewona ama-PV bayazuza ngokubamba iqhaza kulolu hlelo, njengoba kubonakala ocwaningweni lwecala le-Intermittent Transition. Izinsiza kufanele zamukele indima yokusetshenziswa okubonakalayo ohlelweni oluhlongozwayo lokuhlanganisa inqubo ye-P2P. "
Bethule uhlelo lwabo kokuthi “Ukusebenzisa ibhukwana ukusiza ukulinganisa okuzenzakalelayo kwe-peer-to-peer virtual metering yesizukulwane esatshalaliswa yi-solar photovoltaic,” esanda kushicilelwa ku I-Solar Energy Advans.
