Frequency response is a crucial aspect of power quality, representing the system's response to generated power and applied loads. Understanding frequency variations when integrating renewable energy into a microgrid is essential, considering the variability of renewable sources due to weather conditions. This study focuses on Covenant University as a case study, aiming to identify the optimal renewable energy source and permissible penetration levels in relation to the average hourly peak load, without disrupting the existing system's operations. The study calculates the average peak load demand at Covenant University as 1.42MW, with a generation capacity of 4.5MW. The MATLAB-Simulink software was employed to design and simulate the solar PV system, while maintaining a constant average peak load throughout the simulations. Penetration levels of 5%, 10%, 15%, 20%, and 25% were considered. Simulation results indicate that the system's frequency response remains within permissible limits up to a solar PV penetration level of 21% (289.2kW) relative to the average hourly peak load. Beyond this point, the frequency starts deviating beyond the acceptable limits. The findings of this study provide valuable guidance for integrating solar PV into Covenant University's existing campus system, revealing that the maximum solar PV penetration without energy storage is 21% (298kW) of the average hourly peak load, resulting in frequency deviations of 50.89Hz and 49.22Hz.
