基于调频备用容量约束的储能规划方法

Energy Storage Planning Method Based on Frequency Modulation Reserve Capacity Constraints

建设新型电力系统是构建新型能源体系的重要任务,而随着新能源大规模并网将导致电力系统频率响应能力下降,灵活性条件资源不足。以电化学为主的新型储能作为优质的灵活性调节资源,有望在电力系统动态频率支撑中发挥重要作用。本文从电力系统备用容量管理及实际电网一次调频需求角度出发,提出了一种基于调频备用容量约束的储能规划方法,并通过算例进行了验证,可作为省级储能规划的参考。

Building a new type of power system is an important task in constructing a new energy system.However,the large-scale integration of new energy sources into the grid will lead to a decline in the power system's frequency response capability and a lack offlexible resources. New types of energy storage, mainly electrochemical, as high-quality flexible regulation resources, are expected to play an important role in the dynamic frequency support of power systems.This paper,starting from the perspective of power system reserve capacity management and the actual grid's primary frequency control demand,proposes an energy storage planning method based on frequency modulation reserve capacity constraints, and verifies it through case studies, which can serve as a reference for provincial-level energy storage planning.
