Title: Automatic Generation Control of TCPS Based Hydrothermal System under Open Market Scenario: A Fuzzy Logic Approach
Authors: C. Srinivasa Rao and S. Siva Nagaraju and P. Sangameswara Raju
Abstract: This paper presents the analysis of Automatic generation control (AGC) of a two-area interconnected thyristor controlled phase shifter (TCPS) based hydrothermal system in the continuous mode using fuzzy logic controller (FLC) under open market scenario. The effects of nonlinearities like deadband and generation rate constraint on the system have also been investigated. The traditional AGC two-area system is modified to take into account the effect of bilateral contracts on the dynamics. It is possible to stabilize the system frequency and tie-power oscillations by controlling the phase angle of TCPS which is expected to provide a new ancillary service for the future power systems. A control strategy using TCPS is proposed to provide active control of system frequency. Simulation results show that the limitations of integral controller can be overcome by including Fuzzy concept and thereby the response of frequency and tie line power can be improved substantially following a load change in any area. Further dynamic responses for small perturbation have been observed, considering FLC and integral controller and the results of both have been compared.
