摘　　要：随着可再生能源的快速发展,光伏能源在电力系统中占据了重要地位。分布式光伏集群的利用能够提高能源利用效率和降低成本,但也带来了一系列的挑战。为了保证光伏集群系统的稳定运行和最大功率输出,本文提出了一种鲁棒性虚拟同步化控制策略,参考虚拟同步发电机的内部惯性结构,进一步采用混合鲁棒控制方法,在抑制模型建立不准确和功率耦合不确定性对系统控制性能的影响方面取得了显著成果,从而实现系统快速动态恢复。With the rapid development of renewable energy,photovoltaic energy has occupied an important position in the power system.The utilization of distributed photovoltaic clusters can improve energy efficiency and reduce costs,but it also brings a series of challenges.In order to ensure the stable operation and maximum power output of the photovoltaic cluster system,this paper proposes a robust virtual synchronization control strategy.Referring to the internal inertia structure of the virtual synchronous generator,a hybrid robust control method is further adopted to achieve significant results in suppressing the impact of model establishment inaccuracy and power coupling uncertainty on system control performance,thereby achieving rapid dynamic recovery of the system.
