摘要

对模拟转子运动方程和改变功率给定值两类光伏虚拟同步发电机调频控制策略和实现方式进行分析，对比研究了两类控制策略在调频启动时间、振荡风险、功率支撑方式、惯量响应死区等方面的差异。基于风光储电站虚拟同步发电机示范工程现场实测数据，研究了两类光伏虚拟同步发电机控制策略的实际支撑效果与差异化特征。针对现场实测中发现的两个性能缺陷，提出了功率深度利用和光储协调优化控制策略，借助RT-LAB硬件在环仿真平台验证了所提控制策略的有效性。

Abstract

This paper analyzes different damping coefficient control strategies and additional frequency regulation characteristics control strategy of photovoltaic virtual synchronous generators(PV-VSG). The differences between these two strategies

which is in frequency regulation start-up time

oscillation risk

mode of supporting power

inertia response dead zone and so on

are compared and studied. Based on field data

the actual frequency modulation effect and characteristics of the two different strategies are shown. To improve the system performance

a new control strategy is proposed to make the full use of power from PV-VSG and effectively coordinate the photovoltaic and energy storage to stabilize the grid frequency. The effectiveness of the control strategies is verified on a RT-LAB semi-physical simulation platform.
