Power Transaction Strategies Based on Stackelberg Game Model and Smart Contract Between PV Users and Electric Power Aggregator Ge Xiangdi, Hou Hui, Wang Yifan

Abstract

In order to accelerate the realization of the global “double-carbon” goal, we introduced game theory into the electricity market to formulate a reasonable strategy to transaction. A strategy of purchasing and selling power is proposed in this paper. Firstly, we devised a transaction strategy based on Stackelberg game. Then, we designed an incentive mechanism for this game. This mechanism takes the reputation value of users as an index and adopts the smart contract technology in blockchain, which can reduce the transaction risk. The proposed strategy can encourage users to use electricity reasonably and sale surplus electricity to the grid. In addition, it can increase the benefits of electric power aggregator and users effectively.
