Frequency Regulation in Hybrid Renewable Power System using Fractional Order PID under Various Uncertainties

Frequency regulation of hybrid power system integrated with conventional units and renewable energy sources is studied in this work using a conventional and non-integer controller. The hybrid system contains various renewable sources as solar and wind in addition electric vehicle and battery resources. Here, Proportional Integral Derivative (PID) controller is used as the conventional controller and Fractional Order PID (FOPID) controller is used as the non integer controller in order to get more adjustable time and frequency responses. In this paper, a rigorous simulation and comparison of dynamic performances of PID and FOPID controllers is carried out under different operating conditions.
