Simscape Based Modelling & Simulation of MPPT Controller for PV Systems

摘要

In modern time electricity demand is increasing day by day and due to limitations of fossil fuels and other environmental issues the whole world is looking for alternatives. Renewable energy sources are proving their strength. Solar energy is the most important renewable and sustainable energy system. The modelling of solar cell and array is very much time consuming because it has so many complex mathematical equations. Sometimes we need only the solar cell for its applications without going into details of its complex equations. MATLAB has provided a very helpful and handy tool for solar cell in Simscape library that uses the physical language for modelling. But before using that tool It becomes necessary to learn the interfacing between Simscape and SPS tools with the use of some converters. In this paper step by step procedure is shown for modelling of solar array with the use of Simscape library. To extract the Maximum power from solar array, MPPT technique is necessary so in this paper Incremental conductance method is used for MPPT and results are shown in the form of various characteristics of solar array.
