Abstract: | With the deepening reform of the electricity market in the retail side, it is of great signifcance to study the direct electricity trading on the distribution side with the participation of multimicrogrids. In this paper, a Nash bargaining model based on cooperative game theory is proposed to deal with the direct electricity transaction between multi-microgrid and load aggregator, taking the optimal beneft of each participant under the traditional transaction mode as the disagreement point of bargaining, so that the participants of the game can obtain Pareto optimal beneft. The model is a non-linear and non-convex problem, which is diffcult to solve directly. Therefore, it is divided it into two sub-problems:solving payment and maximizing alliance benefts. In order to protect the privacy of each agent, the maximizing alliance benefits uses alternating direction method of multiplier to solve the distributed optimization problem. In the process of solving the model, only the expected transaction power is exchanged between the two parties. The simulation results show that the model can effectively improve the operational effciency of both sides of the transaction. |
