摘要：

微电网中虚拟同步机（VSG）需要搭配储能模块满足持续的供电需求,如何对储能模块的荷电状态（SOC）进行控制就非常重要。针对该问题,本文在传统VSG控制的基础上,增加了基于比例积分（PI）调节器的SOC控制环节,并在建立小信号模型的基础上,通过极点配置的方式设计了调节器参数,使得系统具有良好的动态性能,最后通过仿真验证了该控制策略的正确性和可行性。

Abstract:

Virtual synchronous generator (VSG) in microgrid requires storage module to meet the needs of continuous power supply demand. It is vital to control the state of charge (SOC) of the storage module. To solve this problem, based on the traditional VSG control, SOC control section is added on the basis of proportional integral (PI) controller, and regulator parameter is established through pole assignment on the basis of small signal model, which makes the system a good dynamic performance. At last, the correctness and feasibility of the control strategy is verified by simulation.

Key words: Virtual synchronous generator, state of charge, pole assignment
