Description

PV is one of the most promising renewable energy resources that converts solar energy into electricity with environment friendly manner. The aim of this book is to study, design and performance analysis of grid-connected PV system as follows: - System modeling; that is composed of two-diode model to describe the I-V and P-V characteristic curves of PV system performance. Modeling of PV system represents the main goal in the design and performance study of grid-connected PV system using accurate parameters of PV module. - Improving the efficiency of grid-connected PV system to operate at maximum power point (MPP) with the aid of perturb and observe (P&O) tracker via DC/DC converters. Although, P&O algorithm is widely applied due to its simplicity, costless and easy implementation, it suffers from instabilities, and oscillation around MPP at steady state. This book presents a modified P&O algorithm to overcome such drawbacks and improve MPPT performance of PV system under rapidly changes of weather. - Investigating the design performance of grid-connected PV inverter that suitable for low voltage appliance of distributed grid network at 220V and 50HZ.
