论文摘要
分布式优化方法已广泛应用于电源分配系统的优化,尤其是用于网格边缘协调。现有的分布式优化算法应用于电源分配系统需要分布式代理之间的许多通信回合,并可能在困难的非线性设置中构成收敛挑战。通信网络参数也会显着影响算法的性能。在本文中,我们提出了一种基于等效的网络近似,分布式优化算法,该算法使用系统的数字双胞胎(DT)在优化中采用仿真来解决三相不平衡分布系统的最佳功率问题(OPF)。提出的方法是使用网络物理共模拟平台实施的,以验证在压力交流下提出的分布式算法的鲁棒性。使用IEEE 123-BUS测试系统对所提出的方法进行了彻底验证。
Distributed optimization methods have been extensively applied for the optimization of electric power distribution systems, especially for grid-edge coordination. Existing distributed optimization algorithms applied to power distribution systems require many communication rounds among the distributed agents and may pose convergence challenges in difficult nonlinear settings. The communication network parameters also significantly impact the algorithm's performance. In this paper, we propose a scalable, equivalent network approximation-based, distributed optimization algorithm that employs simulation within optimization using the system's digital twin (DT) to solve the optimal power problems (OPF) for a three-phase unbalanced distribution system. The proposed approach is implemented using a cyber-physical co-simulation platform to validate the robustness of the proposed distributed algorithm under stressed communication. The proposed approach is thoroughly validated using the IEEE 123-bus test system.
