摘　　要：针对传统虚拟同步发电机(VSG)控制策略在光储一体系统中动态调节性能不佳的问题,提出了一种基于幂函数控制的协同自适应控制策略。该策略采用构造幂函数型自适应控制方法,协同优化虚拟惯量和阻尼系数以改进系统动态特性。在分析相应控制原理的基础上增加控制环节得到改进的控制方法,并对该方法和其它典型的VSG控制方法进行了仿真和对比。结果表明相比其它典型虚拟同步发电机控制策略,该方法较好地减小了系统超调量、缩短了调节时间,具有更高的系统功率和频率稳定性。To solve the problem of poor dynamic regulation performance of the conventional virtual synchronous generator(VSG)control strategy in a PV-storage integrated system,a synergistic adaptive control strategy based on idempotent function control is proposed to construct an idempotent function-type adaptive control method to synergistically optimize the virtual inertia and damping coefficients to improve system dynamic behavior.Based on the analysis of the corresponding control principle,the improved control method is obtained by adding control links,and the method is simulated and compared with other typical VSG control methods.The simulation results show that compared with other typical virtual synchronous generator control strategies,this method better reduces the system overshoot,shortens the regulation time,and has higher system power and frequency stability.
