Design and Analysis of Modified Single P&O MPPT Control Algorithm for a Standalone Hybrid Solar and Wind Energy Conversion System

Abstract

In this paper, a modified single P&O MPPT control algorithm for hybrid solar and wind energy system is designed and analyzed for the standalone application. The extraction of maximum power from the intermittent and erratic nature renewable energy sources are the main target in the hybrid renewable energy system. In the literature, many researchers developed an individual MPPT control algorithm for solar and wind energy system, which in turn increases the number of control algorithms in a hybrid system. In this paper, a single modified P&O control algorithm is proposed to extract maximum power from both the sources simultaneously. The performance of the proposed P&O MPPT control algorithm is analyzed by comparing with the conventional individual P&O MPPT control method under different weather conditions. A 560 W PV system and 500 W wind system is considered with conventional Boost converter topology for the design of the hybrid system and it is simulated in Matlab/Simulink environment to analyze the performance of proposed control algorithm.
