提出了通过可及的计算（FAR）进行的正式分析，以有效地评估网络微电网的稳定性，这是由于高渗透分布式能源而引起的异质不确定性的存在，直接计算出所有可能的动态轨迹的边界。传统时间域模拟或直接方法无法实现的稳定信息。然后将技术与估计与可及的边界有关的这些方案的特征值结合在一起，以识别系统的稳定性范围。网络微电网系统与这些显着特征的稳定性距离有多远。网络微电网。
A formal analysis via reachable set computation (FAR) is presented to efficiently assess the stability of networked microgrids in the presence of heterogeneous uncertainties induced by high penetration of distributed energy resources. FAR with mathematical rigor directly computes the bounds of all possible dynamic trajectories and provides stability information unattainable by traditional time-domain simulations or direct methods. An advanced Geršgorin theory with a quasi-diagonalization technique is then combined with FAR to estimate eigenvalues of those scenarios pertaining to the reachable set boundary to identify systems’ stability margins. Extensive tests show that FAR enables efficient analysis on impacts of disturbances on networked microgrid dynamics and offers a potent tool to evaluate how far the networked microgrid system is from its stability margins. These salient features make FAR a powerful tool for planning, designing, monitoring, and operating future networked microgrids.
