Game on Pricing of a Micro Grid Based on Multi-agent System Considering New Energy Consumption

Abstract

Based on the analysis of the characteristics of micro grid, we established a micro grid power market with the multi-agent theory to mode the interaction between micro grid and large grid. Then the Nash game theory was used to analyze the bidding strategy of micro grid considering a power market with imperfect competition. We found that the bidding strategy with high proportion factor and low cost quotation of micro grid can maximize the system’s profit. Although the change of any micro grid’s bidding strategy will lead to the adjustment of bidding strategy of other micro grids, the system will eventually achieve Nash equilibrium. Finally, we obtained the optimal bidding strategy and selection scheme of micro grid to maximize the micro grid’s profit through numerical analysis.
