جایگذاری بهینه تعویض شیر بار در شبکه های توزیع با استفاده از روش SA-TLBO

This paper presents a multi-objective optimal location of on-load tap changers (OLTCs) in distribution systems at spirit of distributed generators (DGs) based on Teaching–Learning-Based optimization coupled with Simulated annealing algorithm (SA-TLBO). In the suggested algorithm, teacher and learner phases are modified by SA. The proposed algorithm utilizes several teachers and considers the teachers as an external cache to store found Pareto optimal solutions during the search process. The proposed approach allows the decision maker to take one of the Pareto optimal solutions (by trade-off) for different applications. The performance of the SA-TLBO algorithm on a 70-bus distribution network in comparison with other methods such as GA, PSO, SA and TLBO is remarkable.
