Multiobjective Strategy for Optimized Load Breaker Switch Placement to Improve Distribution Network Performance and Reliability

This paper examines the issue of load management in electrical distribution networks, with a focus on the optimal placement of telecommunication load breaker switches (TCLBSs). The main innovation of this study lies in the introduction of a dual‐objective optimization framework that simultaneously aims to minimize energy not supplied (ENS) and preserve critical loads. This approach enables network operators to prioritize switch placement based on the importance of each objective, offering a level of flexibility, and comprehensiveness not thoroughly addressed in previous studies. To solve this problem, an iterative graph‐based search algorithm is employed, which dynamically identifies the optimal locations for switch installation. By leveraging graph theory, the proposed method significantly reduces computational complexity and enhances responsiveness to changing network conditions. According to simulation results on the IEEE 33‐bus network, switch locations change as the priority of critical loads increases, and the proposed strategy greatly improves the reliability and performance of the power distribution network during peak demand periods. This dual‐objective approach, with adjustable settings, enhances the efficiency of load management, and strengthens network dependability.
