Abstract: This paper presents a fractional order PID (FOPID) to control the operation of a stand-alone hybrid energy system with a wind turbine based on permanent magnet synchronous generator (PMSG) and a battery bank. In order to maintain the DC-link voltage at its reference value, regardless the variation in wind speed and load impedance a FOPID controller using a DC-DC buck-boost converter fed by a lead acid battery bank is used. The line to line AC output voltage regulation based on PID controller to supply RL load with constant amplitude and frequency has been achieved. The proposed FOPID controller is examined through simulation using MATLAB-simulink and experimentally via an experimental test bench under step change variation of wind speed and load impedance. The obtained simulation and experimental results using FOPID controller show better performances than the conventional PID regulator in terms of less settling time and lower overshoot in the transient state as well as a minimum steady state oscillation.
