Abstract

This research presents a Teaching Learning Based Optimization (TLBO) algorithm to solve Optimal Reactive Power Dispatch (ORPD) problem. The primary objective of this paper is to minimize the active power transmission losses by the optimal settings of the control variables within their limits and avoiding violations on the constraints. TLBO is a population- based algorithm and requires few algorithm specifications to compute making it a recommended option to solve various degrees of optimization problems. The TLBO algorithm was implemented using MATLAB programming and by incorporating MATPOWER, the algorithm was tested on IEEE 30-bus test system to solve the ORPD problem. The optimal values obtained from the TLBO algorithm was validated on PowerWorld- a power system visualization tool. The results obtained from the algorithm were compared with other algorithms in the literature and TLBO proved to be an efficient prediction method for solving the ORPD problem.
