COMPARATIVE ANALYSIS OF AN IMPROVED PSO BASED MPPT ALGORITHM USING DC-DC CONVERTER FOR PHOTOVOLTAIC SYSTEM
Yoganandini A. P.* and Anitha G. S.
Many Different approaches have been proposed for Maximum Power Point Tracking (MPPT). It is plays an essential role in operations of any Photo-Voltaic (PV) cell design. By using PSO can achieve reduction in steady state oscillations when it reached maximum power points, this can track MPP for different environmental conditions like Partial shading conditions, temperatures fluctuations of insulations, Faces many challenges because of various factors like uncertainty resulting higher degree of fluctuation in current and voltage of PV cell. This paper presents a novel approach of different analysis of modified PSO algorithms with simple design and computations. Peak power to be extracted from the PV cells using PSO based MPPT. The outcomes of the model are analyzed and compared with tracking speed, accuracy and faster time response and fast convergence easy implementations, better analysis of current-voltage- power for given state of PV cells compared with traditional PSO systems.[Full Text Article]
