TCPS and SMES Coordinated Supplementary Control for Interconnected Power System Stability

Abstract

This work presents the implementation of Thyristor controlled phase shifter (TCPS) and superconducting magnetic energy storage (SMES) as an effective supplementary control strategy in the interconnected power system (IPS) stability. Dual area traditional hydro-thermal (DATHT) is selected as the investigative IPS model and carried out the analysis for 10% step load disturbance (SLD) in area 1. Fruit fly technique (FFT) based tilt-integral-derivative-filter (TIDN) is enacted for the DATHT system as a secondary regulator. Time delays (TDs) are conceived with the DATHT system to get a more practical investigation and their impact on performance is also demonstrated. Later, the investigation is stretched to the adoption of TCPS-SMES control and the simulation analysis reveals the enhancement in DATHT performance.
