An optimal active power control strategy of islanded microgrid with diverse communication delays

摘要

Communication networks are increasingly applied in smart grid for information exchange and optimal operation. This paper presents an optimal active power control strategy for islanded microgrid in the presence of communication delays. The control strategies are fully distributed. The impact of the diverse communication delays and the effectiveness of the algorithm are analyzed by using the Generalized Nyquist criterion. The proposed approach can minimize the total cost and maintain the supply-demand balance of the microgrid. Several case studies are carried out to verify the effectiveness of the proposed approach.
