A novel meta-heuristic algorithm based optimized load frequency controller

Abstract

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.

A Novel 2DOF Fractional Controller for Wind-Solar Integrated Power System

“…The 2-DOF PID controller is widely used in multi-area power systems to reduce frequency disturbances during load fluctuations [17]. Recently, a 2-DOF-PIDD controller is introduced to reach the objectives of the LFC [18]. The application of these advanced controllers in LFC of interconnected power systems with renewables is limited in the literature.…”

“…The application of these advanced controllers in LFC of interconnected power systems with renewables is limited in the literature. Few works are reported in [18]- [21]. In [19], a cascade controller is applied with PID blocks around LFC with renewable sources.…”
