Design of frequency control on hybrid wind-diesel with PID-firefly

Power quality in hybrid wind turbine system with diesel (wind-diesel) affected by change of frequency fluctuation. Low - frequency oscillation due to the transmission network is long and low time constant and the high gain Automatic Voltage Regulator (AVR). Hybrid wind turbine system with diesel (wind-diesel) is controlled by Proportional Integral Derivative (PID) controllers. Trial - error method is used to determine the value of the gain of PID, so it is very difficult to get the optimum value. Study on the design control using Artificial Intelligent (AI) algorithms to find the optimum value of firefly from gain PID. The optimum value of the PID gain is used to adjust the frequency of the load with the matlab Simulink program. Hybrid wind turbine system with diesel (wind-diesel) with PID - firefly has a response which indicates that large overshoot and settling time response is being reduced and faster than a hybrid wind turbine system with diesel (wind-diesel) with PID trial-error.
