论文摘要
本文提出了一种新的基于分布共识的控制方法，用于完全基于逆变器的微电网（MGS）的电压和频率控制。所提出的方法包括电压控制中的主动功率共享，以提高反应能力共享精度，从而推广一些现有的二次频率和电压控制方法。首先，频率由分布式二级频率控制调节。其次，电压由分布式平均电压控制和分散的个体电压控制调节。它在电压调节，主动和反应性分享精度之间提供了可调节的权衡。因此，它避免了滥用牺牲反应能力共享精度的精确电压法规，这是现有方法的常见问题。提出的方法是以分布式的方式实现的，该方法不需要先验了解MG网络结构和负载，因此可以确保可伸缩性。仿真结果表明，在不同的操作模式下，所提出的控制器在上述三个目标之间实现了不同的折衷。
This paper proposes a new distributed consensus-based control method for voltage and frequency control of fully inverter-based islanded microgrids (MGs). The proposed method includes the active power sharing in voltage control to improve the reactive power sharing accuracy and thus generalizes some existing secondary frequency and voltage control methods. Firstly, frequency is regulated by distributed secondary frequency control. Secondly, voltage is regulated by distributed average voltage control and decentralized individual voltage control. It offers a tunable trade-off between voltage regulation, active, and reactive power sharing accuracy. Therefore, it avoids the abuse of sacrificing reactive power sharing accuracy for exact voltage regulation which is a common issue of existing methods. The proposed method is implemented in a distributed way that does not require a prior knowledge of the MG network structure and loads and hence can ensure scalability. Simulation results shows that the proposed controller achieves different compromise between the above three targets under different modes of operation.
