The paper presented here outlines an approach to design a damping controller which is used for providing the pulses to the gates of the energy storage based type static synchronous compensator (STATCOM). The energy storage type STATCOM is one of the AC transmission system devices which are also known as FACTS devices. It is an advanced flexible device, which controls injection and absorption of both active and reactive power to the power system. The integration of an energy storage system into

... FACTS device helps to provide much needed flexibility for mitigating transmission level power flow problems. It also provides a better power oscillations damping. The control strategy is carried out using proportional integral controller. The desired model is implemented in MATLAB simulink using simpower system toolbox. Power oscillations are introduced in the power system and their effects on the power system generator's and load's current voltage with and without the use of STATCOM are shown in simulink waveform. The simulation results and waveforms are used to verify the effectivity of the proposed control method to provide power oscillation damping.
