Research on Distributed Power Trading Based on Blockchain Technology

Abstract

A large number of grid-connected distributed photovoltaic and wind power generation projects bring challenges to traditional electricity market trading. A distributed power trading model based on blockchain technology is designed in this paper, and the transaction process is introduced in detail. The transaction is established in an annual cycle and settled monthly. The trading model adopts the average price of the sellers' and buyers' quotation price by matching, and the matching transaction takes into account the influence of the differences in transmission prices between different buyers and sellers. The matching transaction mechanism and the monthly transaction settlement mechanism are elaborated. A distributed power trading system based on blockchain technology is developed on the Ethereum platform. Combined with a distributed power trading example, the feasibility of the trading system for distributed power trading is verified.
