摘　　要：新能源并网规模的不断扩大和并网容量的大规模增加给电网的调节能力和新能源消纳问题带来了严峻的挑战,采用储能系统参与调峰是推进新能源发展的重要手段。为此,提出了综合考虑储能用户满意度和新能源调峰需求的电力系统双边交易联合运营模式和交易模型,以各方综合效益最大为目标,建立新能源侧、电网侧和用户侧的投标和出清模型,其中储能用户与新能源于日前完成双边交易以直接减小电网的调峰服务压力,最终由电网侧的储能消纳剩余新能源出力。算例仿真结果表明,所提运营模式不仅有效地调动了用户主动调峰的积极性,还减小了电网侧储能的调峰压力,在促进新能源发展和保障电力系统稳定运行方面具有重要意义。The continuous expansion of new energy grid-connected scale and the massive increase of new energy grid-connected capacity have brought severe challenges to the regulation capacity of power grid and the consumption of new energy. Using energy storage system to participate in peak regulation is an important means to promote the development of new energy. Therefore,the joint operation mode and transaction model of power system bilateral transaction are proposed comprehensively considering the satisfaction degree of energy storage users and the peak regulation demand of new energy. With the goal of maximizing the comprehensive benefit of each party,the bidding and clearing models of new energy side,power grid side and user side are established. Among them,energy storage users and new energy complete bilateral transaction day-ahead to directly reduce the peak regulation service pressure of power grid,and finally the energy storage at the power grid side consumes the remaining output of new energy. The simulative results show that the proposed operation mode not only effectively mobilizes the enthusiasm of users for active peak regulation,but also reduces the peak regulation pressure of energy storage at the power grid side,which is of great significance in promoting the development of new energy and ensuring the stable operation of power system.
