Load Frequency Control of Wind Diesel Hybrid Power Systems via Predictive Control

Wind-diesel hybrid power systems are efficient in supplying power to remote areas. To maintain a sustainable and dependable power supply, the frequency of the system must be kept a constant. This paper studies decentralized load frequency control for wind-diesel hybrid systems based on predictive control. In order to implement in practice, this paper approximates the predictive control with conventional PID control structure. The method is applied to design PID controllers for two wind-diesel hybrid power systems. Simulation results show that the method can achieve better results compared with traditional method (ISE).
