Abstract This article deals with automatic generation control of a multi-area interconnected thermal system in different modes using intelligent integral and proportional-integral controllers. Appropriate generation rate constraint has been considered for the thermal generation plants. The two cumulated thermal areas are considered with reheat turbines. Performances of reheat turbine on dynamic responses have been investigated. Further, selection of suitable integral and proportional-integral controllers has been investigated with a minority charge carrier inspired algorithm. Cumulative system performance is examined considering with different load perturbation in both cumulative thermal areas. Further, system is investigated with different area control errors, and results are explored.

Generation Control

Wind farms can contribute to ancillary services to the power system, by advancing and adopting new control techniques in existing, and also in new, wind turbine generator systems. One of the most important aspects of ancillary service related to wind farms is frequency regulation, which is partitioned into inertial response, primary control, and supplementary control or automatic generation control (AGC). The contribution of wind farms for the first two is well addressed in literature; however, the AGC and its associated controls require more attention. In this paper, in the first step, the contribution of wind farms in supplementary/load frequency control of AGC is overviewed. As second step, a fractional order proportional-integral-differential (FOPID) controller is proposed to control the governor speed of wind turbine to contribute to the AGC. The performance of FOPID controller is compared with classic proportional-integral-differential (PID) controller, to demonstrate the efficacy of the proposed control method in the frequency regulation of a two-area power system. Furthermore, the effect of penetration level of wind farms on the load frequency control is analyzed.
