Photovoltaic (PV) is known as an intermittent energy source so that the impacts need to be calculated by the developer. In order to ensure the presence of PV does not cause the reliability of the system interrupted, developers are required to perform the stability study before the integration. In this paper, voltage stability study is done by using various PV capacities ranging from 5 MWp to 15 MWp in systems with a capable capacity of 90.79 MW using software ETAP 12.6.0. PV generation is set at the maximum site irradiance where power drop due to weather condition. The analysis shows the system stabilized in less than 50 seconds where the voltage disturbance does not exceed 10% for PV with a capacity of 5 and 10 MWp which is connected to a distribution network. Meanwhile, PV with a capacity of 15 MWp requires load release in order to regain stability.
