Abstract: The distributed active power control problem is explored by equating wind turbines to multi-agent systems in this paper. Both time delays and unknown topological relations are considered in the proposed model. Using the graph discovery algorithm, the algebraic connectivity of the graph is found in advance. Further, a proportional control protocol is proposed based on the adjustable margin of different wind turbines. Moreover, the proposed distributed controller not only handles the problem of supply-demand balance between the wind farm and power grid but also regulates the output power of individual wind turbines based on their capacities. Finally, simulations are performed on the wind turbines to illustrate the validity of the proposed method.
