Abstract

In this chapter, the STATCOM characteristics are analyzed when it is utilized for improving the voltage stability. This chapter aims to analyze the STATCOM in the abc coordinates, and its impact over the power system under steady state and transient conditions is studied. Mathematical description of the main components is included to represent the dynamic behavior. These elements are formulated by differential equations in order to demonstrate how the STATCOM influences overall power system performance and voltage stability margins. The proposed methodology is validated on a Synchronous Machine Infinite Bus (SMIB) and on the New England test power system, which comprises 39-buses, 46-transmission lines, and 10-generators.
