Since intermittent nature of distributed generation and uncertainty in load behavior, the existing secondary control are not sufficient to deal with robustness and fast response. In this paper, attacked from a cooperative based control perspective inspired to the tracking consistency paradigm, a robust nonlinear distributed secondary voltage controller is proposed to achieve fast compensation for the islanded microgrid. Employing sparse communication, the proposed control strategy can achieve a compromise between the conflicting goals of voltage regulation and reactive power sharing. As the distributed architecture only requires the information of its own and its neighbor, the use of centralized controllers is avoided and the flexibility and scalability of system can be enhanced. Finally, the stability analysis is provided and the simulation results are presented to verify control performance under rapid load changes, robustness under communication failure, and flexibility during plug-and-play operation.

基于分布式一致性的孤岛微电网非线性二次电压控制


由于分布式发电的间歇性和负载行为的不确定性，现有的二次控制不足以处理鲁棒性和快速响应。本文从基于协作的控制角度出发，受到跟踪一致性范式的启发，提出了一种鲁棒的非线性分布式二次电压控制器，以实现孤岛微电网的快速补偿。采用稀疏通信，所提出的控制策略可以在电压调节和无功功率共享这两个相互冲突的目标之间实现折衷。由于分布式架构只需要自身及其邻居的信息，避免了集中控制器的使用，增强了系统的灵活性和可扩展性。最后，提供了稳定性分析和仿真结果，以验证负载快速变化下的控制性能、通信故障下的鲁棒性以及即插即用操作期间的灵活性。
