Cooperative Operation Strategy of Optical Storage Network Based on Cooperative and Non-cooperative Game

To solve the problem of direct electricity transactions between photovoltaic power generation entities and power users, the cooperative and non-cooperative two-stage game theory was used to study the process of cooperative operation between micro-grid system composed of optical storage and power grid in two stages: optimal scheduling and negotiated price. In the first stage, optimal scheduling is used to improve the benefits of the alliance. The mathematical model is built according to the operation characteristics of the microgrid. The alternating direction multiplier method is adopted to avoid the situation that the electricity will cancel each other due to superposition in the transaction process, and the scheduling result is obtained by cooperative game. The second stage first analyzes the impact of electricity price on the transaction mode, builds a negotiation price model between photovoltaic power generation entities and users, improves based on the beetle antennae search (BAS) algorithm, adopts a bargaining model combined with adaptive moment estimation and uses non-cooperative game income distribution to obtain the optimal transaction price. Finally, a numerical example is given to verify the feasibility of the model. The results show that the model not only improves the revenue of micro-grid but also improves the PV consumption level through the guiding role of the market.
