Automation of the supplier role in the GB power system using blockchain based smart contracts

摘要

An electricity supply smart contract was developed anduddemonstrated to perform pre-time-of-use priceudnegotiation between demand and generation and posttime-udof-use settlement and payment. The smart contractudwas demonstrated with 1000 loads/generators withudusages simulated using lognormal probabilityuddistributions. It combines payment of deposit, negotiationudof price based on estimates, settlement based on actualudusage and enactment of payments using crypto-currency.udThe settlement procedure rewards customers thatudadjusted to balance the system. The smart contract wasudwritten in the Solidity programming language andudimplemented with a simulated Ethereum blockchain usingudtestrpc and go-ethereum. In the example test case, a priceudwas agreed, settled and payment enacted.
