STATCOM modeling for voltage and angle stability studies

Abstract:

This paper proposes and validates models to accurately represent static synchronous shunt compensators (STATCOM) in voltage and angle stability studies of powers systems. The proposed STATCOM stability models are justified based on the basic operational characteristics of this flexible AC transmission system (FACTS) controller for both phase and PWM control strategies. These models are first validated by means of EMTP simulations on a test system, and then are implemented into two different programs used to study voltage and angle stability issues in the system. All details of the model implementation, the controls used, and the data for the test system are provided in the paper. © 2003 Elsevier Science Ltd. All rights reserved.
