摘　　要：针对新能源渗透率不断增高带来的电网稳定性问题,提出一种采用虚拟电厂技术将分散的分布式新能源机组联合起来参与黑启动的频率及电压优化控制方法。首先以暂态频率及电压偏差量最小为优化目标,建立分布式新能源机组集群初期黑启动控制模型。其次,利用多智能体一致性算法并结合分层控制的方式,实现分布式电源集群初期黑启动电压和频率控制的整体优化及功率调度。最后通过仿真验证了分布式优化控制方法的有效性,仿真结果表明相比于集中控制方法,该方法对频率及电压有更好的控制稳定性。Targeting the problem of power grid stability caused by the increasing penetration rate of renewable energy,the paper proposes a frequency and voltage optimization control method using virtual power plant technology to unite dispersed distributed renewable energy units participating in black start.Firstly,the initial black start control model of distributed renewable energy unit cluster is established aimed at minimizing the transient frequency and voltage deviation.Secondly,the multi-agent consensus algorithm and hierarchical control method are used to realize the overall optimization and power scheduling of the initial black-start voltage and frequency control of distributed generation cluster.Finally,the effectiveness of the distributed optimal control method is verified by simulation,and the simulation results show that the proposed method has better control stability in the frequency and voltage than the centralized control method.
