摘要

以电化学、飞轮等中短时储能作为独立主体参与电网调频可有效减少火电频繁的负荷调节需求,增加频率调节的灵活性。现阶段参与二次调频辅助服务的独立储能电站的功率与容量尚缺乏合理的规划方法,该文通过采用日前调度计划、日内滚动优化的方式确定各并网主体的出力曲线,从而确定调频资源的基准运行点。构建包含电网频率稳定性指标和经济性指标的多目标函数,建立储能参与的区域电网二次调频模型,获取电网实时调频需求,确定独立储能电站在不同参与程度下的最优容量规划。最终,通过多时间尺度下的案例模型,验证该文策略实现独立储能电站辅助电网二次调频的经济性和安全性。

Abstract

Using electrochemical energy storage, flywheels, and other medium- and short-term storage systems as independent entities to participate in grid frequency regulation can effectively reduce the frequent load adjustment demands of thermal power plants and increase the flexibility of frequency regulation. Currently, there is a lack of reasonable planning methods for the power and capacity of independent energy storage stations participating in secondary frequency regulation ancillary services. This paper determines the output curves of all grid-connected entities by using day-ahead scheduling plans and intra-day rolling optimization, thereby establishing the benchmark operating point for frequency regulation resources. This paper then constructs a multi-objective function that includes frequency stability and economic indicators of the power grid, establishes a regional power grid secondary frequency regulation model with energy storage participation, obtain real-time frequency regulation demand of the power grid, and determines the optimal capacity planning of independent energy storage power stations under different levels of participation. Finally, through case models on multiple time scales, the proposed strategy is verified to achieve the economic and security benefits of independent energy storage stations assisting with grid secondary frequency regulation.
