This paper investigates the application of an Electric Vehicle (EV) aggregator in a Load Frequency Control (LFC) system and analyzes its impact on stability regions. By adjusting the controller parameters through droop coefficient and participation factor, the EV aggregator contributes positively to the stability regions under the LFC-EV concept, as proven through MATLAB-Simulink-based studies.
In this paper, an Electric Vehicle (EV) aggregator is included both primary and secondary frequency control loops of a single-area Load Frequency Control (LFC) system via the droop coefficient and participation factor, respectively. Then, its impact on the stability regions in controller parameter space is investigated in detail. The effect of the Gain and Phase Margin Tester (GPMT) coefficients and integrator order of the Fractional-Order PI (FOPI) controller on the stability region are also examined. Finally, MATLAB-Simulink-based studies prove that the EV aggregator contributes positively to the stability regions under the LFC-EV concept.
