Compare the performance of TCPS-SMES and SMES-SMES controller in Automatic Generetion Control of two area interconnected hydrothermal system

Frequency deviation and inter-area transmitted power oscillations are under local load disturbances. This is a major concern in performance and control of interconnected power systems. In this paper, in order to minimize frequency deviations and increase production control performance, a structure of automatic control for power system production using thyristor-controlled phase-shifter, superconducting magnetic energy storage, as well as governor backlash nonlinearities effect on load frequency control is presented. The aim of this paper is to compare oscillations’ damping and stability evaluation when superconducting magnetic energy storage (SMES) is used in an area and thyristor-controlled phase-shifter (TCPS) in series with transmission line and SMES in both areas considering governor backlash nonlinearities in an interconnected two-area network. Simulation results reveal that the network with SMES-SMES is better than TCPS-SMES in terms of load frequency control.
