摘要

传统的虚拟同步发电机（VSG）控制策略由于缺少动态调节虚拟惯量和阻尼系数的能力,已无法满足电网实际接入的需求。为解决这一问题,首先针对VSG控制的工作特性建立VSG输出阻抗的小信号模型,绘制出回率矩阵特征值的奈奎斯特曲线图,分析VSG处于不同电网强度下的稳定性;然后,结合VSG有功功率环的小信号模型,推导出VSG的虚拟惯量和阻尼系数取值范围,进而引出基于自适应神经模糊推理系统（ANFIS）的光储VSG控制策略;最后,在Matlab/Simulink中搭建光储VSG仿真模型,仿真结果验证该控制策略的有效性。

Abstract

Traditional virtual synchronous generator （VSG） control strategy is unable to meet the actual grid integration requirements due to inability to dynamically adjust virtual inertia and damping coefficient. To address this issue, this article first establishes the output impedance model of the VSG based on the working characteristics of VSG control. The Nyquist curve of the eigenvalues of the return ratio matrix eigenvalues is plotted to analyze the stability of VSG under different grid strengths. By combining the small-signal model of the VSG active power loop, the range of virtual inertia and damping coefficient values for VSG is derived. This leads to the proposal of a control strategy for photovoltaic and storage system VSG based on an adaptive neural fuzzy inference system （ANFIS）. Finally, a photovoltaic and storage system VSG simulation model is built in Matlab/Simulink, and the simulation results validate the effectiveness of this control strategy.
