Abstract

Wind power installed capacity is expected to reach 1,000 MW and 6,200 MW in the Vietnam Power System (VPS) in 2020 and 2030, respectively. But detailed dynamic analysis of the wind power plants' (WPPs) integration into the VPS is still scarce. In this paper, first, the impact of WPPs' integration on the dynamic voltage performance and the wind turbine generator (WTG) low-voltage-ride-through (LVRT) requirement in the VPS for the year 2020 is studied. Then, case studies on the VPS for the year 2020 with different levels of wind penetration and different values of WTG's maximum allowable voltage sag are studied. Simulation results show that the 2020 VPS can lose as much as 1,000 MW (100%) of WPP's generated power following a severe contingency if the WTG's LVRT capability is not considered. In some scenarios, the loss of WPPs' generated power can cascade into a power system islanding situation which in turn could cause massive load shedding (15%) in the load-rich subsystem and result in wide variations of the electrical parameters of generators near the islanding boundary.
