摘要/Abstract

摘要： 针对新能源发电逐步取代火电导致电网调频能力下降的问题，搭建了一种光储（photovoltaic-energy storage, PV-ES）系统模型，提出利用逆变器空闲容量参与系统调频/调峰的控制策略；设置储能电池禁用区、调频区、调峰充电区、调峰放电区4类荷电状态分区，保证储能电池的调峰和调频2种模式能够协调运行；构造了基于荷电状态（state of charge, SOC）反馈的储能电池的最大出力约束系数来优化其出力，延长储能电池的使用寿命；最后，在MATLAB/Simulink软件中搭建光储系统仿真模型。典型算例仿真和经济性分析表明：在所提控制策略下光储系统能够利用逆变器空余容量参与电网的调频/调峰，该控制策略有实际推广意义。

Abstract: The increasing replacement of renewable energy for thermal power results in the decline of power grid frequency regulation capability. To solve this problem, a photovoltaic-energy storage (PV-ES) system model is established and a control strategy is proposed, which utilizes the idle capacity of the inverters to participate in peak shaving and frequency regulation. To ensure the two modes of peak shaving and frequency regulation of the energy storage battery operate coordinately, the energy storage battery is set into four types of state of charge (SOC) zones, including disable zone, frequency regulation zone, peak shaving charging zone and peak shaving discharging zone. The maximum output constraint coefficient of the energy storage battery is constructed based on SOC feedback to optimize the output and prolong the service life of the energy storage battery. Finally, a PV-ES system model is established in MATLAB/Simulink software. The simulation results and economic analysis for a typical case show that with the proposed control strategy, the PV-ES system has the ability to participate in peak shaving and frequency regulation of power grid by utilizing the idle capacity of the inverters.

Key words: photovoltaic storage system, frequency regulation mode, peak shaving modes, integrated control strategy, state of charge zone
