Energy Storage by Static Synchronous Compensator with Power Oscillation Damping Controller

Abstract

This paper offers with the design of an adaptive power oscillation damping (POD) controller for a static synchronous compensator (STATCOM) prepared with Energy storage. That is performed utilizing a signal estimation system based on a modified recursive least square (RLS) algorithm, which allows a quick, selective, and adaptive estimation of the low-frequency electro-mechanical oscillations from locally measured indicators for the period of power system disturbances. The proposed approach is amazing in increasing the damping of the process at the frequencies of interest, additionally within the case of procedure parameter uncertainties and at quite a lot of connection points of the compensator. First, the evaluation of the impact of active and reactive power injection into the power system will likely be implemented making use of a simple two-computing device method model. A manipulate process that optimizes active and reactive vigour injection at various connection points of the STATCOM will likely be derived utilizing the simplified model. Small-signal evaluation of the dynamic performance of the proposed manage approach might be applied. The effectiveness of the proposed control system to furnish power oscillation damping regardless of the connection factor of the device and within the presence of method parameter uncertainties shall be tested by means of simulation.
