| Abstract | ||
| This study introduces a multi-zone of the Iraqi system model powered by various energy sources, where decentralized controllers operate independently to manage the system’s frequency. The system model comprises two zones: the first zone represents the north and central power plants of Iraq. The second zone incorporates the Euphrates and southern power plants of Iraq. The data of the system is obtained from the Iraqi Ministry of Electricity. To evaluate the system’s performance, a load disturbance is applied to the system. The study examines various control methodologies, first with an Optimised Proportional-Integral-Derivative (OPID) controller as the baseline, subsequently progressing to an Optimised Fractional Order (OFOPID) controller. These controllers are utilized to maintain the frequency of each zone around 50 Hz and maintain the power of Tie-lines between the zones at schedualled values. The parameters of the controllers are refined using the Ant-Colony Optimization (ACO) Algorithm. Three case studies are conducted. In the first and second case studies, 10% of load disturbance is subjucted individually to the first and second zones, respectively. In the third case study, the 10% of load disturbance is given for both zones simultaneously. Simulation results show that improvement about 97%, 85% for settling time and peak respectively in area1 and 94%, 97% in area2 respectively in comparison with classical PID controllers and using Iraqi dataset. | ||
