- In this paper, a new frequency control strategy is proposed for islanded microgrid. Due to characteristics of islanded microgrid, the load variation and the new energy disturbance can be predicted by the ultra-short-term prediction. By using feedforward control method, the load disturbance can be roughly adjusted in advance. However, load variation and new energy disturbance in islanded microgrid cannot be precisely predicted and there must be prediction error. Therefore, feedback control is used to eliminate prediction error. Specifically, considering characteristics of different units, wind turbines and diesel engines are used in feedforward control part, and energy storage systems in the feedback control part. Besides, this paper proposes an allocation method on feedforward and feedback resources, which can improve resources utilization to a certain extent. Simulation results show that the proposed control method can improve the frequency control effect for islanded microgrid.
