论文摘要
在本文中，我们在事件触发的通信下引入了针对岛上AC微电网的分布式二级频率控制方案。提出了一个积分类型事件触发的机制，每个分布式生成器（DG）异步并定期检查其触发条件，并确定是否更新其控件输入并将其状态广播到相邻的DGS。与对微电网的二级控制的现有事件触发的策略相反，在提出的基于采样DATA的事件触发的机制下，DG不必同步到公共时钟，并且每个单独的DG都依靠其自身的时钟来定期检查其触发条件。此外，提出的方法有效地降低了通信和计算复杂性。我们提供了足够的条件，在该条件下，所有DGS的频率渐近地融合到了共同的参考频率值。最后，通过模拟MATLAB/SIMULINK环境中建立良好的岛AC微电网基准的不同场景来验证我们所提出的方法的有效性。
In this paper, we introduce a distributed secondary frequency control scheme for an islanded ac microgrid under event-triggered communication. An integral type event-triggered mechanism is proposed by which each distributed generator (DG) asynchronously and periodically checks its triggering condition and determines whether to update its control inputs and broadcast its states to neighboring DGs. In contrast to existing event-triggered strategies on secondary control of microgrids, under the proposed sampled-data based event-triggered mechanism, DGs need not be synchronized to a common clock and each individual DG checks its triggering condition periodically, relying on its own clock. Furthermore, the proposed method efficiently reduces communication and computation complexity. We provide sufficient conditions under which all DGs' frequencies asymptotically converge to the common reference frequency value. Finally, effectiveness of our proposed method is verified by simulating different scenarios on a well-established islanded ac microgrid benchmark in the MATLAB/Simulink environment.
