Test Systems for Voltage Stability Studies

Abstract:

This paper describes the two test systems for voltage stability studies set up by the IEEE PES Task Force on 'Test Systems for Voltage Stability Analysis and Security Assessment' under the auspices of the Power System Stability Subcommittee of the Power System Dynamic Performance Committee. These systems are based on previous test systems, making them more representative of voltage stability constraints. A set of representative results are provided for both systems, with emphasis on dynamic simulation. They illustrate various aspects such as long-term dynamics, voltage security assessment, real-time detection, and corrective control of instabilities. The value for educators, researchers and practitioners are emphasized.
