Battery Energy Storage System-Based Stabilizers for Power System Oscillations Damping

Abstract

To ensure secure and reliable operations of power systems, rapid damping of power system oscillations is unavoidable. This paper addresses the improved damping characteristics of a power system by integrating the Energy Storage System (ESS) such as a battery into a Flexible AC Transmission System (FACTS) device named the Battery Energy Storage System (BESS). Design of the BESS-based stabilizers is created to enhance the power system dynamic stability and damping profile. A modified Philips-Heffron model of a Single Machine Infinite Bus bar (SMIB) power system with BESS is established and analyzed. Improved damping characteristics of the power system oscillations are selected as performance criteria for the proposed design. Simulation results show the superior performance of the proposed design as compared to the coordinated design of BESS and conventional Power System Stabilizers (PSS). All the simulations are carried out in MATLAB/SIMULINK.
