摘　　要：可再生能源的消纳推动着储能技术的发展,共享储能因其分散性特征得到了广泛的关注。在共享储能优化调度中,面临多主体之间的利益分配问题,因此提出一种基于纳什谈判理论的共享储能电站运行优化方法。文章构建了共享储能电站及工业用户的联合模型,基于纳什谈判理论建立各运营主体的合作运行模型,根据均值不等式将此非凸非线性问题等效为系统收益最大化和电能交易支付谈判2个子问题,采用交替方向乘子法(alternating direction method of multipliers,ADMM)对其进行分布式求解。算例选取3家典型工业用户参与的共享储能联合系统,通过合作谈判前后对比分析,得出所提优化方法可以有效提高各主体的效益,同时促进新能源的消纳。The consumption of renewable energy promotes the development of energy storage technology.Shared energy storage has attracted extensive attention because of its decentralized characteristics.In the optimal scheduling of shared energy storage,there is a problem of benefit distribution among multiple subjects.Therefore,this paper proposes an operation optimization method for shared energy-storage power station applying Nash negotiation theory.In this paper,the joint model of shared energy-storage power station and industrial users is constructed,and the cooperative operation model of various operators is established according to Nash negotiation theory.According to the mean inequality,the non-convex nonlinear problem is equivalent to two sub-problems:system revenue maximization and power transaction payment negotiation,which are solved by alternating direction method of multipliers(ADMM).Through the comparative analysis before and after the cooperative negotiation,it is concluded that the optimization method used in this paper can effectively improve the benefits of each subject and promote the consumption of new energy.
