摘要/Abstract

摘要： 能源绿色低碳转型下，电力系统调峰调频缺口日益增大，储能凭借灵活爬坡和双向调节特性，可作为独立主体或虚拟电厂（virtual power plant，VPP）内部成员参与协调解决调峰调频及新能源消纳问题。分析了国内外储能参与电力市场概况，建立VPP聚合多分布式能源（distributed energy resource，DER）的调峰竞标模型及整体效益最大的调峰竞标策略；在以发电、调频成本最小化为目标的电能量和调频市场联合出清模型基础上，引入效率因子体现快速调频资源的优势。算例验证了VPP竞标策略下储能分配的收益优于独立运营模式；传统和快速调频交易品种参与日前市场设计的火-储联合出清模型较顺次出清模式具备更高的社会效益，引入效率因子能提升优质调频资源参与市场的积极性和节约电网总调频成本的目的。

Abstract: Under the green and low-carbon energy transition, the gap of peak and frequency modulation in the power system is increasing. With the flexible climbing and bidirectional regulation characteristics, energy storage can be an independent subject or an internal member of a virtual power plant (VPP) to coordinate and solve the problems of peak and frequency modulation and new energy consumption. This paper analyzes the general situation of energy storage participating in the electric power market in China and abroad and establishes the VPP aggregated multi-distributed energy resource (DER) peak modulation bidding model and peak modulation bidding strategy with maximum overall benefit. Based on the joint clearing model of the electricity energy and frequency modulation market with the goal of minimizing the cost of power generation and frequency modulation, an efficiency factor is introduced to reflect the advantages of fast frequency modulation resources. An example is given to verify that the income of energy storage distribution under the VPP bidding strategy is better than the independent operation mode. Compared with the sequential clearing mode, the fire-storage combined clearing model of traditional and fast frequency modulation trading varieties participating in the day-ahead market design has higher social benefits. The introduction of the efficiency factor can enhance the enthusiasm of high-quality frequency modulation resources to participate in the market and save the total frequency modulation cost of the power grid.
