Abstract

Interconnected microgrids are a new type of power system that interconnects multiple microgrids through tie-lines and communications to realize coordinated control and optimized management. In many existing applications, the interconnected microgrids need a central controller to realize the scheduling of generators, energy storage systems, and flexible loads. However, each microgrid belongs to different owners, rendering the centralized control inconvenient. Thus, a novel distributed method for solving the economic dispatch problem (EDP) of interconnected microgrids is proposed in this paper. First, the EDP is reformulated to incorporate a penalty, and decomposed to subproblems for the microgrids. Then, a penalty-based distributed economic dispatch method (PDED) is proposed accordingly for each microgrid to solve the entire problem in parallel. Rigorous theoretical analysis has been provided to guarantee the equivalence of reformulation and the convergence of PDED to optimal solutions. Simulations have also been conducted to demonstrate the effectiveness and advantages over existing methods. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

一种新型的互联微电网分布式经济调度方法

互联微电网是将多个微电网通过联络线和通信互联起来，实现协同控制和优化管理的一种新型电力系统。在现有的许多应用中，互联微电网需要一个中央控制器来实现发电机、储能系统和灵活负载的调度。然而，每个微电网属于不同的所有者，这给集中控制带来了不便。因此，本文提出了一种解决互联微电网经济调度问题的分布式方法。首先，将EDP重新表述为包含惩罚的问题，并将其分解为微电网的子问题。在此基础上，提出了一种基于惩罚的微电网分布式经济调度方法（PDED），以并行解决整个问题。为保证重新表述的等价性和PDED收敛于最优解提供了严格的理论分析。仿真也证明了该方法的有效性和优于现有方法的优点。©2025日本电气工程师协会和Wiley期刊有限责任公司。
