摘要

研究了孤岛微电网二次控制中存在通信压力大的问题

提出一种新的动态事件触发机制来调度微电网间的通信

不仅将下垂控制无法控制的电压和频率调节到期望值

同时避免使用全局信息。与现有的研究结果相比

利用线性矩阵不等式（LMIs）设计出理想的触发机制和控制协议

所提出的触发机制涉及内部动态变量

能动态调整触发阈值

扩大事件触发时间间隔的下限

大幅度降低各控制器的通信次数。由于控制方案是完全分布式的

各发电单元只与其邻居进行信息交换

从而降低了对通信网络的要求

也提高了系统的稳定性

且这些内部动态变量在排除芝诺（Zeno）行为方面起着重要作用。最后

通过仿真得到论证。

Abstract

In this paper

the problem of high communication burden in the secondary control of islanded microgrids is investigated

and a new dynamic event triggering mechanism is proposed to schedule the communication between microgrids not only to regulate the voltage and frequency that cannot be controlled by the drop control to the desired values

but also to avoid the use of global information. Compared with the existing research results

the linear matrix inequality is used to design the ideal triggering mechanism and control protocol

and the proposed triggering mechanism involves internal dynamic variables

which dynamically adjusts the triggering thresholds

enlarges the lower limit of the event triggering interval

and drastically reduces the number of communication times among the controllers. Since the control scheme is fully distributed

there is information exchange between each generating unit only with its neighbours

which reduces the requirements of the communication network and improves the stability of the system. These internal dynamic variables play an important role in excluding Zeno behaviour. Finally

the argumentation is obtained through simulation.
