Research on cooperative game model for distributed photovoltaic microgrid based on blockchain

In recent years, as the dual-carbon target has been proposed, the installed capacity of distributed photovoltaic (PV) systems has been increasing annually. As a novel networking approach, a microgrid can integrate distributed energy resources and enable the effective grid connection and utilisation of distributed PV energy. Based on this, a distributed PV microgrid group power trading model is proposed, which is based on blockchain technology and game theory. This provides a new approach to optimise the electricity market of microgrids. The cooperative game model of microgrid groups can effectively solve the interest issues of microgrid users. The simulation results demonstrate that due to the transparent and open nature of blockchain, microgrids can effectively engage in dynamic games, achieve the nearby consumption of distributed PV energy, and verify the feasibility and effectiveness of the model. © 2023 Inderscience Enterprises Ltd.
