Blockchain Based Potential Game Model of Microgrid Market

Microgrid is effective to realize the complementary advantages, efficient accommodation, and grid-connected long-distance transmission of renewable energies. Based on the distributed topological structure of blockchain similar to that of microgrid market, the overall framework of microgrid market is designed. Taking a full consideration of economy and energy utilization of microgrid market, this paper introduces the conceptions of game theory and potential game to convert constraints to state space, and build a microgrid operation optimization model based on the ordinal potential game of state variables with two-way time-varying information interaction. The state balance of this model is proved. In different information interaction conditions of microgrid market, the strategic learning algorithm of games is used to solve this potential game model, and the operation of microgrid market is optimized. Simulation results show that the application of this potential game model with rational microgrid participants enables all devices of the microgrid to operate at the optimal level, increases the revenue of the microgrid, and improves the utilization rate of renewable energy.
