The distributed generators (DGs) and energy storages systems (ESSs) have different droop characteristics for power sharing in autonomous microgrids (MGs). In previous research, the distributed secondary control is proposed for only one specific type of units, and relies on periodic communications among neighbors. In this paper, a unified distributed real power sharing control scheme based on the dynamic event-triggered mechanism is proposed for droop-governed DGs and ESSs. A unified power sharing strategy is proposed where the power are fairly shared among all DGs and ESSs considering their different power ratings and capacities, while state-of-charges among ESSs are balanced. In the meantime, a distributed event-triggered control scheme with a novel dynamic triggering mechanism is designed to reduce the communications among controllers. Besides, the proposed event-triggered mechanism is sample-based and only uses the largest and the second smallest eigenvalues of the Laplacian matrix to design the controller gain and event-triggered parameters. To validate the proposed control design, a MG test system with detailed component models is built in the OPAL-RT real-time simulator. The results demonstrate the effectiveness and performance of the proposed controller.

通过分布式动态事件触发控制，对岛上微电网中的发电机和储能装置进行统一的有功功率共享

分布式发电机（DG）和储能系统（ESS）具有不同的下垂特性，用于自治微电网（MG）中的功率共享。在先前的研究中，仅针对一种特定类型的单元提出了分布式辅助控制，并且依赖于邻居之间的定期通信。本文提出了一种基于动态事件触发机制的分布式分布式有功功率共享控制方案。提出了一种统一的功率共享策略，其中考虑到DG和ESS的不同额定功率和容量，在所有DG和ESS之间公平地共享功率，同时均衡ESS之间的充电状态。同时，设计了一种具有新型动态触发机制的分布式事件触发控制方案，以减少控制器之间的通信。除了，提出的事件触发机制是基于样本的，并且仅使用拉普拉斯矩阵的最大和第二最小特征值来设计控制器增益和事件触发参数。为了验证所提出的控制设计，在OPAL-RT实时模拟器中构建了带有详细组件模型的MG测试系统。结果证明了所提出控制器的有效性和性能。
