MATLAB-Based Modeling tool for designing, predicting and analyzing Grid Tied Photovoltaic Systems

Abstract

Planning a photovoltaic (PV) system is complex. Many different factors must be taken into account such as site information, module type and inclination of the modules, level of irradiation, choice of the most suitable inverter, etc. To ease the planning process, computer based tools must be utilized. In this paper, a MATLAB-based modeling tool to design, predict and analyze grid - tied PV systems is presented. This software has a user friendly interface which requires a minimum of data in order to present your optimum system and examine its performance in a clear graphical form. The user can explore different combinations and scenarios to meet the proposed design requirements. Simplicity, accuracy and ability to adapt the designed tool to any updates in both site information and system components would probably make it an excellent tool for educational and research purposes.
