Today, the expansion of power sources is the main task to meet the development of demand. Therefore, Da Nang City has been approved to build the Khanh Son waste incineration power plant in the near future. The Khanh Son power plant project not only helps to reduce a large amount of waste in the area but also provides electricity supply directly to the city, increasing the budget for that locality. However, the connection of this power plant to the system will modify the operating parameters of the grid which may cause some negative impact on the regional power system. Therefore, the main aim of this paper is to simulate various operation modes of the system such as steady-state mode, short circuits, and transient to evaluate the impact of the connection of the new power plant on the national power. The result shows that the Khanh Son power plant helps to reduce the overload of the main cable during the high load scenario, the stability of the system is enhanced significantly. Based on the simulation results, some recommendations to ensure the stabilizing of the grid have been proposed as well.
