Abstract

Growing pollution and depleting fossil fuel reserves have encouraged exploration and exploitation of nonconventional energy sources since oil crisis faced in late 1970. Among available renewable energy sources, photovoltaic (PV) generation is supposed to play major role in future energy scenario. High installation cost and low efficiency has been major challenges for its wide spread usage. This work focuses on reducing cost of generation from PV and enhances power tracking with low cost controller design module. Maximum power point tracking (MPPT) highly depends on atmospheric conditions and exposure of PV panel surface to solar radiation. So MPPT technique should be good enough in dynamic atmospheric conditions. Different algorithms are design in which the Perturb and Observer (P and O) and Incremental conductance (INC) are widely used MPPT techniques. Present work focus to design the cost effective PV controller module. In the PIC technology C/C++ Coding is used to design the algorithm but the drawback of the PIC technology is the complex coding and debugging is much more difficult. Emphasizing on DsPIC30f4011, in which automatic C/C++ code for the algorithm generated in the MATLAB using simulation and can easily be dumped on the respected pins and for the completion of the coding MP-Lab IDE software is used which interface between the DsPIC chip and DsPIC hardware kit. For the compilation process complier XC16 and C30 complier is used. Efforts have been made to design the cost effective and reliable operation of PV system using IGBT based boost converter and rectifier circuit thereby ensuring the minimum switching losses, reducing size and cost of controller. The new topology is well suited for drives and renewable energy applications.
