摘　　要：随着能源短缺、环境污染等问题日益突出,大量的可再生能源和储能(ESS)开始接入用户侧。由于可再生能源出力的间歇性造成的问题较为突出,因此研究电力市场环境下分布式光储的运营策略,对提高用户用电的经济性、ESS资源的利用率及系统的消纳能力具有重要意义。该文以社区为背景,借鉴航空等领域的超售运营策略,以社区用户群总收益最大为目标,建立了超售策略下社区共享光储联合运行的优化模型。对基于超售模式下共享光储社区能量管理系统进行了算例仿真,结果表明对于光储系统推广初期发掘用户积极性方面,少量超售ESS资源参与调频市场是一种经济高效的运营策略,能够充分利用ESS资源,促进清洁能源消纳。With the increasingly prominent problems of energy shortage and environmental pollution,a large number of renewable energy and energy storage system(ESS)have begun to be connected to the user side.Due to the prominent problems caused by the intermittent output of renewable energy,studying the operation of photovoltaic energy storage in the electricity market environment is of great significance to improve the economic efficiency of users’electricity consumption,the utilization of ESS resources,and the absorption capacity of the system.Based on the background of the community,this paper draws on the oversold operation strategy of aviation and other fields and establishes an optimization model for the joint operation of sharing photovoltaic energy storage in the community aiming to maximize the total revenue of community users.A case simulation is carried out on the sharing photovoltaic energy storage community energy management system based on the oversold mode.The results show that in terms of exploring user enthusiasm in the initial promotion of the photovoltaic storage system,overselling a small amount of ESS resources in regulation market is a cost-effective operation strategy,making full use of ESS resources and promoting the integration of clean energy.
