Research on the Distributed Photovoltaic Trading and Settlement Model Based on the Energy Blockchain

With the new energy market-orientated reform in China, every resident has the same opportunity as industrial users to participate in the energy market. The paper focuses on the three photovoltaic trading modes “full power on-grid, surplus power on-grid, and grid parity,” to allow power producers and consumers to make a consensus on the trading. The flat topology of the blockchain can realize the direct interaction of energy flow, capital flow, and information flow among different distributed nodes. Running the smart contract with power trading settlement rules can reduce trading friction, improve the efficiency of purchasing and selling new energy, and promote the digitalization of the retail energy market.
