“…When taking RESs as undispatchable sources, the conventional formulation of the joint scheduling of generation and reserves has been well addressed such as the affinely adjustable robust optimal power flow in [16] and the endogenous approach proposed in [24]. As the time scale of AGC is from 30 s to 15 min, which is much shorter than the start-up and shut-down time of SGs, we only consider spinning reserves [38], [39]. Based on the output transformation, VSRs are also dispatchable.…”

“…Integral and derivative gains of the same controller is represented by 𝑘 𝑖 𝑖 and 𝑘 𝑑 𝑖 .From the literature survey, it is observed that the multiple derivative controllers enhance the actual response over normal controllers. Therefore, the multiple derivative component concept is inserted in the PIDD controller, and the output of the controller is modified from (1) to (2) given by:…”

“…"During load perturbations, secondary control mechanism helps to balance the active power generation, demand and reduces the frequency deviations caused by the power imbalances". In the case of regular conventional plants, generation control is possible with secondary control action schemes [2]. Therefore, several controllers are investigated to improve the interconnected power system frequency profiles [3].…”

This work proposes a 2-degree-of-freedom proportional-integral-double-derivative (2-DOF PIDD) controller to improve frequency profiles of an IEEE 39 bus 10 generator 3 area New England interconnected power system during step load perturbations. To increase the system’s dynamic response, parallel derivative components are used in the secondary controller mechanism, and comparisons are made with proportional, integral and derivative (PID) and 2-DOF PID controllers to illustrate the advantage of the proposed controller scheme. The ideal gain values of the PID, 2-DOF PID, and 2-DOF PIDD controllers are achieved using a novel evolutionary algorithm called the intelligent water drops (IWD) algorithm, which is used for the first time for the load frequency control problem for a 3-area power system. The results proved that the proposed controller is superior to the existing controllers. Simulations are done in the MATLAB-Simulink® environment.
