Mitigation of SSR in a Series Compensated Wind Power System by using SMES with STATCOM

In recent years, the large penetration of wind power system is considered as an effective means for power production due to this continuously growing nature of wind power system, power utilities does not consider the power quality problems that are issued by the system. They are going for other power system stability analysis. This will produce an integration of large wind power system with the electrical network that are series compensated for ensuring bulk power transfer. But this series compensated transmission system will produce an unwanted effect of subsynchronous resonance. SMES (Super Conducting Magnetic Energy Storage) with STATCOM (Static Compensator) controller provide an efficient damping for Subsynchronous Resonance that will enhance power system stability in addition to real and reactive power compensation. And it will reduce MVA rating required by the STATCOM when it is operated alone. Here output of PV cell is used instead of a constant dc source. This work mainly concentrate for the coordinated operation of STATCOM control with SMES scheme for the series compensated wind power system for damping power system oscillation is simulated using MATLAB/SIMULINK in power system block set.
