Parameter estimation of distribution transformer using harmony search algorithm

Abstract

In this work, the harmony search algorithm is applied to optimize the different unconstrained non linear benchmark functions viz. Sphere & Rosenbrock to highlight the efficacy of the algorithm and also observe the effect of user defined parameters of harmony search algorithm in the function optimization problems. The study of harmony search algorithm and its modified/improved version in the field of electrical engineering has also been surveyed. To estimate the parameters of distribution transformer, two objective functions have been taken: (1) minimize the voltage regulation (2) minimize the voltage regulation and maximize the efficiency simultaneously. Then the estimated results are compared with measured values and other different techniques existing in literature.
