摘要: 在开放的电力市场环境下,微电网内部各运营主体间可进行电能交易。以微电网内部各运营主体与配电网单独交易时的成本作为谈判破裂点,提出了一种基于合作博弈理论的多运营主体微电网日前经济调度纳什议价方法,该方法可在使各运营主体获得帕累托最优成本的同时实现微电网系统的成本最小化。依据该方法建立的纳什议价模型为非凸非线性模型,不易直接求解,将其分解成两个凸的子模型并采用ADMM算法依次求解以起到保护运营主体隐私的作用。仿真给出了议价前后微电网内部各运营主体的成本对比,并进一步分析了孤岛模式下多运营主体间的纳什议价策略。

Abstract: In the deregulated electricity market environment, the power trading can be carried out among the operators in the micro-grids. In this paper, we take the cost of individual transactions between operators in a micro-grid and power distribution network as the disagreement point of bargaining, and propose a day-ahead economic dispatching Nash bargaining method for multi-operators in micro-grids based on Nash cooperative game theory. This method can minimize the cost of micro-grid systems while each operator obtains Pareto optimal cost. The Nash bargaining model based on this method is a non-convex and non-linear model, which is not easy to solve directly. This paper decomposes the Nash bargaining model into two convex sub-models and uses ADMM algorithm to solve them sequentially in order to protect the privacy of operators. The simulation gives the cost comparison of each operation agent in the micro-grids before and after the bargaining, and further analyses the Nash bargaining strategy among multi-operators in the island mode.

Key words: micro-grid, multi-operator, cooperative game, Nash bargaining solution, alternating direction method of multipliers
