Reactive power compensation of wind energy distribution system using Distribution Static Compensator (DSTATCOM)

In recent years generation of electricity using wind power has received considerable attention worldwide. Induction machines are mostly used as generators in wind power based generations, since induction machines have a stability problem as they draw heavy reactive power. To improve stability of the system reactive power compensation is provided. In the literature various methods have been already suggested for improving the reactive power using different controllers. This paper deals with voltage stability improvement of a distribution system embedded with Wind Turbine Induction Generator (WTIG) by using power electronics based Flexible AC Transmission Systems (FACTS) based Distribution Static Compensator (DSTATCOM). The behavior of the system during the load condition is investigated. The study is carried out by three-phase dynamic simulation of distribution system component models. Simulation are presented for different cases such as with and without capacitors and also for with and without Distribution Static Compensator (DSTATCOM). The simulation analysis of voltage stability and reactive power compensation of distributed system with Wind Turbine Induction Generator (WTIG) is performed using MATLAB/SIMULINK.
