Description
Summary:PV systems are one of the cheapest and most environmentally friendly types of Renewable Energy Source (RES). The integration of PV systems into electrical systems has a significant impact on power system stability, especially for small signal stability. One important concern in integrating PV systems is the impact of the inertia-less generation unit into an interconnected power system. With the increase PV penetration, it might affect the small signal stability performance of power system when it was subjected to small disturbances in the form of electromechanical oscillation. This oscillation is highly recommended to be well damped, as it can destabilize the system. In the worst-case scenario, undamped electromechanical oscillations can limit the power flow, affecting the operating conditions of the power system and may even cause the system blackout. This study aims to analyze the impact of the integration of PV systems on small signal stability in the case study of Lombok's electrical system. Eigen value analysis is used as method of this research, so the performance of small signal stability of the system can be known and studied. The results of this study showed that the integration of PV systems into Lombok electrical system has a significant influence on oscillatory condition and dynamic response, in particular it can enhance small signal stability performance of the power system.
