Investigation of Performance of Stochastic Beam Search, Variable Neighborhood and Simulated Annealing Algorithms Under Partial Shaded

Abstract

This paper presents a comparison for Maximum Power Point Tracking (MPPT) algorithms such as Stochastic Beam Search (SBS), Variable Neighborhood Search (VNS) and Simulated Annealing (SA) under partial shading conditions. Experimental setup consist of 4 series connected PV module and Buck type DC/DC converter. In this work P/V characteristics of the PV array was collected and analyzed in MATLAB environment for algorithm comparison. Results show that, SA and SBS algorithms can find the maximum power point under all shading conditions with high speed and accuracy.
