Optimal control parameters of controllers in automatic generation control for a two-area hydro-hydro system

Abstract

In this study, three different optimization algorithms are adopted for the sake of comparison of optimal performances and obtaining the optimal values of the gain settings of the devices independently. Optimum control parameters of controller using QOTLBO, TLBO, GA algorithms are applied to the interconnected reheat thermal power system for a two-area hydro-hydro system. The impact of coordinated controllers SMES-SMES and TCPS-SMES on load frequency stabilization for such a hydro dominated system have been evaluated. A control strategy using SMES and TCPS are proposed to provide active control of system frequency. The automatic generation control (AGC) tuning is requiring to minimize the fuel cost as well as to avoid operation of generating units in undesirable changes. The proposed methodology is applied to AGC of an electric power system for real-time control of interconnected power systems. The results indicate that the controllers exhibit better performance.
