Stability Analysis of Two Area Power System in the Presence of DDSG Wind Turbine and Fault

Abstract

The penetration of distributed generation sources in the power system has increased many folds 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 offer many advantages, there are certain technical challenges to operate the system in the presence of increased penetration of distributed generation. This paper investigates the effect of wind power penetration in a standard two area power system. The influence of point of interconnection of Direct Driven Synchronous Generator (DDSG) wind turbine and fault on rotor angle and synchronous frequency has been investigated. Simulation results show that the effect of fault and wind turbine on the system stability is related to the point of installment of wind turbine. It was observed that operation of DDSG wind turbine remains satisfactory under the influence of short duration fault. Furthermore, it was also noticed that point of installment of wind turbine greatly influences the synchronous frequency and rotor angle of neighboring synchronous generator.
