摘要: 本文提出一种仅利用局域信息的孤岛微电网分布式控制方法。该方法利用agent构造通信网络，并进行局域信息交换。Agent根据收集的信息，计算下一时刻分布式电源的输出设定值，从而调整下一时刻分布式电源的输出。本文系统地给出，从任意通信网络为agent导出分布式控制律的一般方法，并且在理论上证明，该分布式控制律不仅能够保证微电网内功率平衡，而且能够使得可控分布式电源输出与其容量成比例。最后，设计两组实验，验证文中提出的分布式控制律有效性。仿真结果表明，当环境和负载变化时，文中提出的方法能够维持微电网内功率平衡，保证功率在可控分布式电源之间按照容量大小进行分配。
Abstract: A distributed control method with local information for islanded microgrids is proposed in this paper. First, a communication network composed of agents is established, on which local infor-mation is exchanged among agents, and agents compute setting points and regulate outputs of distributed generation at the next time step. Furthermore, a systematic method is presented to derive a set of control laws from any given communication network. Moreover, it is proved that the control laws not only balance the system, but also make the outputs of controllable distributed generation proportional to their capacities. Finally, two cases are designed to evaluate the performance of the proposed method. The simulation results show that the proposed methods can maintain power supply-demand balance, and also can guarantee power dispatched proportionally, when load demand and environmental conditions fluctuate.
