Performance Evaluation of PIDD Controller for Automatic Generation Control in Interconnected Thermal System with Reheat Turbine in deregulated environment

This paper present automatic generation control (AGC) of interconnected two equal area thermal system with reheat turbine in deregulated environment and using PIDD controller that compared with other classical controllers. With existence of Electrical industry deregulation, the AGC system has been considered by taking the effect of bilateral contracts into account; it means that any distribution companies (DISCO) may have contracts with any generation companies (GENCO) in other areas. The goal is to improve system parameters such as frequency deviation error, area control error and line transmitted power using above – mentioned controllers. The simulation in MATLAB/simulink shows that the AGC with PIDD controller results in increased dynamic efficiency and improvement in responses.
