Influence of DDSG Wind Turbine and Fault on Stability of Two Area Power System

The penetration of distributed generation sources in the power system has increased many fold in the last few years. This is mainly due to the technological development in solar PV and wind turbines. Although these clean renewable energy sources offers many advantages, there are certain technical challenges to operate the system in the presence of increased penetration of distributed generation. This paper investigate the effect of wind power penetration in a standard two area power system. The influence of system inertia and fault on rotor angle and synchronous frequency has been investigated. Simulation results shows that the effect of fault and wind turbine on the system stability is related to inertia of the system. Furthermore, the bus voltage magnitude significantly decreased during fault and also after fault clearance.
