Abaphandi abavela kwiYunivesithi yaseNtshona yaseKhanada baye bavelisa i-open-source, i-blockchain-based based utility virtual for peer-to-peer (P2P) yorhwebo lwelanga, usebenzisa izivumelwano ezihlakaniphile ukugcina ukuya ku-$ 1,600 (iidola zaseMelika) kwi-10 amakhaya kwiimeko ezifanisiweyo.

Izazinzulu ezivela kwiYunivesithi yaseNtshona yaseCanada ziye zayila inoveli evulelekileyo-umthombo osebenzayo ozimeleyo wokubeka iliso kubasebenzisi bePV kunye nokwenza urhwebo lweP2P. Inkqubo yabo ye-blockchain ye-SolarXchange iteknoloji idala izivumelwano ezihlakaniphile ngokwayo, iququzelele ukuthengiselana phakathi kwabasebenzisi ngeyure. "Sinomdla wokwenene ekusebenzeni kunye nezixhobo zombane ezijoliswe phambili ezifuna ukunika amandla ukusabalalisa i-solar esasazwa ngokubanzi kunye notshintshiselwano lwe-P2P ukwenza igridi yombane eyomelela ngokwenene," umbhali ohambelanayo uGqr Joshua M. Pearce uxelele pv imagazini.
“Kwizinto eziluncedo ezikhetha ukwamkela isizukulwana esasasazwayo kukho iindlela ezahlukeneyo zoshishino. Enye indlela enomtsalane kukwenza ukuba iP2P irhwebe ngombane welanga,” zatsho izifundiswa. “Umba ophambili ngowokuba iinkqubo zokuhlawula zimiselwe ukuveliswa kombane kwindawo enye, indlela entsha yokuhlawula/urhwebo iyafuneka eyenzelwe ukusasazwa kombane. Enye indlela kukusebenzisa itekhnoloji ye-blockchain kuba ivumela ukuthengiselana okukhuselekileyo. "
Usetyenziso lwenoveli lwenyani lusekwe kumanqanaba amabini eekhontrakthi, ezibhalwe kusetyenziswa iSolidity, enye yeelwimi ezidumileyo zekhontrakthi. Kwimeko ye-blockchain, iikontraki ezihlakaniphile ziikhowudi ezenza ngokuzenzekelayo imisebenzi xa iimeko ezithile zidibene. Kwinqanaba lokuqala, indlu nganye ethatha inxaxheba inenkontileka yeNdlu, echaza imeko ngokubanzi yesizukulwana sePV somsebenzisi kunye nemfuno. Kwinqanaba lesibini, i-virtual utility iqhuba ikhontrakthi ye-HouseFactory, ethatha ulwazi kwiikontraka zenqanaba lokuqala, ukugcina umkhondo wemfuno yamakhaya ngamnye kunye nemveliso kunye nokwenza isigqibo sokuba umbane kufuneka utshintshwe nini.
“Uvavanyo lweeyunithi kwindlela nganye yeekhontrakthi zibhalwa kwiSolidity, kwaye idatha malunga nokusetyenziswa kwerhasi kunye neendleko ziyaqokelelwa. Kufuneka kuqatshelwe ukuba 'igesi' kumxholo uthungelwano lwe-P2P lubhekiselele kwiyunithi yokulinganisa iintlawulo zentengiselwano kunye neendleko zokubala hayi igesi yendalo, "litshilo iqela. "Iindleko ezipheleleyo zokuthumela iikhontrakthi zibalwe ngokufudusa iikhontrakthi kwi-blockchain ye-Truffle yendawo kunye nokubuyisela ukusetyenziswa kwegesi kunye nolwazi lweendleko ezivela kwi-terminal output."

Ukulandela ukuvavanywa kwemisebenzi ye-blockchain, ukulinganisa kweJavaScript kuphuhliswa ukusebenzisa izivumelwano kumthwalo wangempela kunye nedatha yokuvelisa i-PV ngonyaka omnye ngeyure. Ukulinganisa kuqwalasela iimeko ezimbini: zombini zibandakanya amakhaya e-10 kunye nolwazi lombane lokwenene oluvela kwisiXeko saseNew York. Uphononongo lwemeko yokuqala, "Oontanga bokwenyani," imele inkqubo evuthiweyo kwixesha elizayo apho zonke izindlu ziyi-prosumers ezinePV yazo.
“Eyesibini i-case study ibizwa ngokuba yi-Intermittent Transition. Kolu phando kukho iindidi ezine zezindlu,” bacacisa oosonzululwazi. “Okokuqala, ikota yezindlu inePV eyiphinda kabini iPV abayidingayo ukuze bazithengele yona, emele amakhaya aneendawo ezinkulu ezinophahla olungakhuselwanga. Okwesibini, ikota enye inePV eyaneleyo yokutshatisa umthwalo wabo wombane minyaka le, nto leyo eza kubonisa indlela uninzi lweenkqubo zePV eziphezu kophahla ziyilwe namhlanje ukuba zithathe ithuba lokulinganisa iimitha ezishiyekileyo. Okwesithathu, ikota enye yezindlu zinesiqingatha kuphela sePV efunekayo ukuze ihambelane nomthwalo wabo, oya kumela izindlu kwiindawo ezincinci okanye kwi-non-optimal. Okokugqibela, ikota enye ayinayo i-PV emele amakhaya ngaphandle kwendawo ekhoyo yePV ngenxa yomthunzi okanye amakhaya angenako ukufikelela kwimali yokufaka iPV.
I-True Peers case study yakhokelela kwi-521 kWh yamandla otshintshiselwano, inikezela ukonga kweendleko zonyaka ezipheleleyo ze-70.78 yeedola phantsi kwexesha lokusetyenziswa (i-ToU) isakhiwo sezinga. Ngokwahlukileyo, i-Intermittent Transition case study ibangele i-11,478 kWh yotshintshiselwano, kunye nokugcinwa kwe-net iyonke ye-$ 1,599.24 phantsi kwesakhiwo sezinga le-ToU efanayo.
"Ukuba nentlukwano enkulu kwimveliso ye-PV ngaloo ndlela kubangele ukwanda okungaphezulu kwamashumi amabini kutshintshiselwano kunye nokonga kweendleko," batsho abaphandi.
"Olu phando lujolise ekuboniseni ukuba kunokwenzeka ukwenza igesi esebenzayo ye-P2P ye-network metering system enokugcinwa okuncinci kubasebenzisi ngelixa ugcina imali yabasebenzisi," liqukumbelele iqela. “Ngenxa yoko, le nkqubo yenza ukuba ubunini bePV kunye nokuthatha inxaxheba kuthungelwano lweP2P lufikeleleke ngakumbi. Bobabini abanikazi be-PV kunye nabangewona i-PV baxhamla ngokuthatha inxaxheba kule nkqubo, njengoko kubonwa kwi-Intermittent Transition case study. Izinto eziluncedo kufuneka zamkele indima yosetyenziso lwenyani kwinkqubo ecetywayo yokubeka kwindawo enye inkqubo yeP2P. ”
Babonise inkqubo yabo “kukusebenzisa incwadi yokujonga i-autonomous peer-to-peer virtual metering yesolar photovoltaic generated generation,” esanda kupapashwa Ukuqhubela phambili kwamandla eSolar.
