Abstract
The world is directing its efforts towards achieving 100% renewable power generation. This paper presents frequency control of a single area power system. The power system is feeding from renewable technologies and storage facilities only which are Photovoltaics, Biogas, Biodiesel, Solar thermal, battery storage and flywheel storage systems. The paper presents models to each renewable technology and energy storage facility. The frequency is controlled by using Nonlinear PID controller (NPID), Fractional order PID controller (FOPID) and Nonlinear FOPID controller (NFOPID). The three controllers are designed by using genetic algorithm at different operating conditions. A comparison between the three controllers at different operating conditions is presented. The results show that NFOPID has better performance than the other two controllers. The simulation and optimization are performed using MATLAB / SIMULINK 2017a.
