摘　　要：针对传统储能变流器控制方法存在的同步速度较慢、有功功率跟踪效果欠佳的问题,提出了一种基于虚拟振荡器控制的储能变流器控制策略。该策略基于虚拟振荡器控制,采用优化惯性权重和学习因子的改进粒子群算法整定控制器参数,避免了有功和无功功率的测量,具有比传统下垂控制更好的动态响应。最后,针对储能系统中2台并联储能变流器在负荷突变情况下进行了相应控制,仿真结果表明,所提新型控制方法具有更快的同步速度和更好的有功功率跟踪性能。In response to the problems of slow synchronization speed and poor active power tracking effect in traditional control methods of energy storage converters,this paper proposes a control strategy for energy storage converters based on virtual oscillator control.This strategy is based on virtual oscillator control,using an improved particle swarm optimization algorithm that optimizes inertia weights and learning factors to tune controller parameters.Avoiding the measurement of active and reactive power,it has better dynamic response than traditional droop control.Finally,corresponding control measures were taken for the two parallel energy converters in the energy storage system under sudden load changes.The simulation results show that the new control method proposed in this paper has faster synchronization speed and better active power tracking performance.
