Renewable Energy is starting to grow rapidly, the use of solar energy in Indonesia has a good development. According to the grid code issued by the national utility company, the maximum standard harmonic limit is 5%. Harmonic is mostly caused by non-linear loads that form a distorted sine wave, which leads the equipment to become hotter faster, adding losses and reducing the equipment lifetime. The simulation method uses ETAP software to obtain values from Total Harmonic Distortion (THD) on the 20kV and 150 kV Beta substations sides with several scenario simulations of photovoltaic power plant integration with a capacity from 5 to 20 MWp with multiple of 5. The simulation results have shown that the maximum THDv value in the scenario at 20 kV Beta substation is 0.26% and at 150kV Beta substation is 0.1%. This value is still below the standard limit, so by the integration of PV plant, system still operates securely.
