摘　　要：虚拟同步发电机的参数众多,参数设计较为复杂,常规方法难以保证设计效果。针对该问题,采用控制变量的方法改变阻尼系数、转动惯量、下垂系数和积分系数值大小,在分析比较不同参数值下虚拟同步发电机的有功、无功动态响应效果的基础上,通过建立以系统动态响应稳定性能为目标的优化函数,提出了一种基于松鼠搜索算法的虚拟同步发电机参数优化设计方法。仿真结果表明,提出的参数优化设计方法能够更准确地选择出合理参数,有效提升了虚拟同步发电机的动态响应性能,具有较好实用性。The parameters of virtual synchronous generator(VSG)are numerous,and the design of parameters is complex,so it is difficult to ensure the effect of parameter design by conventional methods.To solve this problem,the damping coefficient,moment of inertia,sag coefficient and integral coefficient are changed by the method of control variables.On the basis of the analysis and comparison of the active and reactive dynamic response effects of VSG under different parameters,by establishing an optimization function aiming at the stability of system dynamic response,a parameter optimization design method of VSG based on squirrel search algorithm is proposed.The simulation results show that the parameter optimization design method can select reasonable parameters more accurately,effectively improve the dynamic response performance of the VSG,and has good practicability.
