Modeling and Analysis of Local Grid Behaviour Due to Increase Installation of Solar PV System at College of Science and Technology (CST)

This paper discusses the impact on the local grid due to the increased installation and integration of the Solar Photovoltaic system in the college of science and technology (CST). The modeling and analysis done in the MATLAB software were with the future provision of SPV system integrated into the local grid of CST. As of now, there is a hybrid photovoltaic system of three-phase 15.6 kW, a grid-tie photovoltaic system of single phase 5.5 kW, 7 kW of a single-phase standalone photovoltaic system, and a three-phase 10.08 kW grid-tied photovoltaic system yet to be integratedinto grid. With the real-time solar irradiance data collected, the solar PV to grid system has been modeled with both static and dynamic load. The real-time dynamic load has been collected and has been simulated in the MATLAB software with the real-time solar irradiance data collected. Power curves and Voltage Current (VI) characteristic graphs have been derived for analysis.
