Enhancing Oscillation Damping in a Power Network Using EWOA Technique

Abstract

Small oscillations with low frequency are ubiquitous in the power system, and it needs to be damp out to preserve the stability of the system. This paper deals with a power system stabilizer (PSS), including STATCOM for damping oscillations of small frequency. An enhanced whale optimization algorithm (EWOA) is proposed to tune the parameter of the controllers. This paper describes the significance of the FACTS controller and proper coordination between the controllers through novel soft computing technique; a sample power network is considered and modeled with system dynamics.
