Impact of the High Penetration PMSG-Based Wind Turbine on Power System Transient Stability

Nowadays, the cost of installing wind turbines is declining. Companies endeavor to install the high influential rate wind turbine. This desire to use wind turbines indicates that in the future a sufficient part of the electricity will be supplied by wind turbines. The basis of electricity generation in many countries is based on synchronous generators. Wind turbines, which are expected to have a significant share of production in the future, have different dynamics than today's conventional synchronous generators. If a fault occurs in such networks, which consist of wind turbines and conventional synchronous generators, it is significant how the transient stability of the network will be. This paper focuses on the transient stability of the grid when loads are not just static. Previously, the impact of dynamic loads has been ignored. Since dynamic load density is massive, these loads are aggregated to show high accuracy of the transient stability. In this paper, the growing trend of wind turbines on transient network stability is analyzed. This article demonstrates how the presence of wind turbines can assist the grid to be robust during fault. Turbines are variable-speed permanent magnet synchronous generators. Simulations are performed in Simulink / MATLAB environment.
