Description
Summary:	The integration renewable energy sources, characterized by inherently intermittent characteristics and low inertia, into grids introduce several impacts on the network operation such as stability, protection and challenges for management. In this paper, the stability of Con Dao Island grid in Vietnam with high renewable energy penetration, especially photovoltaic (PV) and Wind Turbine (WT) energy, is extensively studied. The main purpose of this paper is to investigate the impacts of high renewable energy integration on stability of this grid. Then, several solutions to the stability issues, including Fault Ride Through (FRT) capability of PV system and implementation of battery, is proposed and validated. Numerous scenarios are considered, including different PV penetration levels (inertia impact) and different events (short circuits and generator outage). The results obtained show the significant impact of PV penetration levels on the grid stability. However, the proposed solutions demonstrate their high effectiveness in addressing the identified instability issues of the grids.
