摘　　要：随着储能在调频市场的不断发展,关于含储联盟体的决策行为对出清结果的影响及最大化自身收益的问题亟待解决。为探求能量及调频市场下申报不同的功率及电价所带来的影响,提出调频参与度概念,并搭建以最大化含储联盟体的收益及最小化配电系统运营商(DSO)成本为目标的双层优化模型,以跟踪中心轨迹内点法及遗传算法对联盟体间的博弈均衡问题进行求解,确定市场的纳什均衡点,得到2个市场下含储联盟体所采取的最优运行策略。最后,在IEEE 33节点系统算例中对所提模型及方法的可行性进行验证,分析不同调频参与度影响下的出清结果及自身收益情况,得出对调频参与度进行合理选择相比只参与能量市场时可获得更高收益的结论。With the development of energy storage in the frequency regulation market,it is urgent to solve the impact of the decision⁃making behavior of alliance containing energy storage on the clearance result and the problem of the maximization of its own profit.First,the concept of degree of participation is proposed to explore the influence of the difference of declared power and price in the energy and frequency regulation markets,and then a bi⁃level optimization model is constructed to maximize the profits of the alliances and to minimize the cost of distribution system operator(DSO).The game equilibrium problem is solved by the path⁃following interior point algorithm and genetic algorithm,and the Nash equilibrium of the markets is achieved for obtaining the optimal bidding strategies of alliances in two markets.Finally,the proposed model and algorithm are validated on IEEE 33⁃bus system.The market clearing result and its own profit under the influence of different degree of participation are analyzed,and the results show that reasonable selection of degree of participation can obtain higher profits.
