Robust automatic generation control in two area thermal-hydro-nuclear plant with 2DOFPID controller

Abstract

This paper addresses the robustness of the automatic generation control and optimized artificial bee colony (ABC) algorithm with 2DOFPID. Now a day's Fractional order control has been widely established as an effective and alternative control approach. In order to increase the performance of dynamic systems factional order controllers has been used. The widely used traditional Proportional Integral and Proportional Integral Derivative (PID) controllers are commonly implemented in the automatic generation control (AGC) to enhance the dynamic performance and to decrease or eliminate steady state error. This study develops two degree of freedom PID (2DOFPID) controller based AGC system to enhance the system stability and performance. This study uses the PI/PID/optimized 2DOFPID having ITAE is the objective function. The paper explores AGC for interconnected power system with diverse source and demonstrates that ABC optimized based 2DOFPID performs better than traditional PI and PID controllers. Furthermore, robustness analysis is carried out with their performance index.
