摘要

针对由多个微电网组成的微电网群系统,因其系统庞大控制器繁多,存在控制目标信息数据难以协调统一的问题。考虑在微电网内分布式电源之间通信存在延迟的情况,建立含稀疏通信网络的微电网群系统模型,提出一种分布式牵制二次控制策略,仅需通过与邻居节点交换功率信息状态,即可实现精确功率共享,提高系统的可靠性和灵活性。最后搭建基于StarSim-HIL的实验平台,并在多种场景下进行实验,结果显示所提方案对微电网群可实现精确的功率共享和微电网区域高度自治,验证了所提策略的有效性。

Abstract

For a MGC system composed of multiple MGs, it is difficult to coordinate and unify control target information and data due to its large system size and numerous controllers. Considering the delay in communication between distributed power sources within a microgrid, a model of a microgrid cluster system with sparse communication networks is established, and a distributed containment secondary control strategy is proposed. By exchanging power information states with neighboring nodes, accurate power sharing can be achieved, improving the reliability and flexibility of the system. Finally, an experimental platform based on StarSim-HIL was built and experiments were conducted in various scenarios. The experimental results showed that under the proposed scheme, the microgrid group could achieve accurate power sharing and a high degree of autonomy in the microgrid region, verifying the effectiveness of the proposed strategy.
