摘要
大容量电池储能在微电网系统中启动了平抑功率波动,孤岛时提供电压和频率参考的作用,成为微电网必备的组网元件。为此,研究储能系统在微电网中的运行控制方法,并与风电系统配合在消纳功率的同时,实现储能的充放电运行。依据传统同步发电机具有惯性、阻尼等特性,提出将虚拟同步机控制技术运用到储能设备变流器上,实现系统的调压调频。采用仿真软件,搭建基于虚拟同步发电机的风储一体发电系统的仿真模型,验证了控制策略的可行性。
Because the large capacity battery energy storage system can stabilize the fluctuation of the power in microgrid system,and provide the reference of voltage and frequencyin the islanding mode,so it has become an essential networking element for microgrid. Therefore,the operation control method of energy storage system in the microgrid was researched in this paper. while coordinating with the wind power system for the purpose of consumptive power,it could realize the charge and discharge energy storage operation. According to the characteristics of inertia and damping of the traditional synchronous generator,the virtual synchronous machine control technology was applied to the converter of energy storage equipment in order to realize the voltage regulation and frequency modulation of the system. Using the simulation software to build asimulation model of wind storage integrated power generation system based on virtual synchronous generator,the feasibility of the control strategy was verified.
