SOLAR MAXIMUM POWER POINT AND PANEL TRACKING USING FUZZY LOGIC CONTROL SYSTEM

Abstract

Globally increase in demand and consumption of energy has led to the energy crisis. In newlineupcoming Renewable Energy Technology applications, Photovoltaic (PV) have emerged as the newlinemost appropriate solution for electricity generation purposes. Photovoltaic s have become a newlineuniversal source for power utility applications in comparison to conventional technologies. newlineSolar Renewable Technology appears most abundant, perennial, environment-friendly and newlinedistributed source of energy all over the globe. The extensive use of PV panels in Distributed newlineand Renewable Electricity Generation is significantly driving Green energy revolution newlineespecially in areas of green computing and ICT (Information and Communication Technology) newlinesustainability. As the efficiency of solar PV panel is low, it becomes mandatory to extract newlinemaximum power from the PV panel at any given period of time. The generation and newlinedistribution of energy by maximization of power output from panels are being propelled by newlineMaximum Power Point Trackers (MPPT). newlineMaximum Power and efficiency in Photovoltaics can be improved by use of MPPT newlineunder distributed environmental conditions (changing temperature and irradiance). This newlineinvolves monitoring of Maximum Power Point (MPP) i.e. optimum point giving highest power newlineoutput under partial or shaded conditions. The attempt is made to develop an efficient newlinephotovoltaic MPPT system to extract maximum power under distributed conditions. The newlinedeveloped system increases efficiency and optimizes the working performance. newlineThe mathematical model for commercially available Solarex MSX-60W panel in the newlineMATLAB-Simulink environment is developed. Simulation is carried out using different newlineparameters that affect solar system performance and model is validated. The performance newlineindicators fill factor and efficiency are determined by changes in open circuit voltage, short newlinecircuit current, voltage, current and power obtained at MPP. The implementation of Buck newlineConverter (step down) is used for power switching and impedance matching when connecting newlinethe pane
