Getting the most electricity out of solar PV while minimizing losses is of the main design objectives of a PV system. Numerous methods for monitoring the PV system's peak performance point have been documented in various literatures in order to accomplish this. Theoretical information on creating and deploying an artificial neural network-based Maximum Power Point Tracking (MPPT) controller for a standalone Photovoltaic systems are implemented. MATLAB/Simulink is used to create a 5KW solar PV array. The neural network is trained and evaluated using real-time data regarding shifting environmental variables, such as temperature and irradiance changes. Simulation results are shown under rapidly fluctuating load circumstances, temperature, and sun radiation. Solar photovoltaic (PV) systems, neural networks, and maximum power point tracking (MPPT) are the keywords.
1.INTRODUCTION The solar energy that sustains life on Earth is also a limitless and sustainable source of power. Over the past 50 years, a large number of research have been conducted to examine various aspects of photovoltaic (PV) cell design and performance characteristics. The ultimate objective has been to develop fully integrated PV modules which may successfully contend with conventional energy sources. There is a growing trend toward the usage of solar cells in both industrial and domestic applications as solar energy is anticipated to play a significant part in future smart grids as a distributed renewable energy source. The global demand for energy is increasing day by day, and it leads to energy crises. Alternative renewable energy sources are needed to meet the growing demand for energy and environmental problems. India has huge solar energy potential. According to the National Institute of Solar Energy (NISE), the country’s solar potential is about 748 GW. The installed capacity of solar energy is 82.64 GW as of April 2024. Earlier solar photovoltaics were very expensive, but today they have become affordable for many consumers thanks to the improvement of technology and the mass production of solar panels. Solar photovoltaic cells are the basic building block of a PV system that converts solar energy into electricity. But PV cells have poor conversion efficiency and it further deteriorate with increasing temperature and decreasing irradiance level because the output current and voltage of solar PV are a function of solar radiation and panel operating temperature. The V-I characteristic of a photovoltaic cell (Figure 1) provides a non-linear curve and it is observed that there is a point on the curve at which the cell produces maximum power at a given irradiance and temperature. This point is called the maximum power point (MPP) and occurs when the rate of change of power with respect to voltage is zero. Various control techniques known as maximum power point tracking (MPPT) are used to monitor the MPP of solar cells.
