Distributed Economic Dispatch Control Method with Frequency Regulator for Smart Grid under Time-Varying Directed Topology

The paper studies a new distributed control method to solve the economic dispatch problem (EDP) under directed topology based on consensus protocol. Electrical equipment is closely related frequency, and frequency of each generator varies independently during operation. Therefore, it hinders realization dispatch. To problem, we combine regulator with protocol, which eliminates effect variation designed algorithm. Meanwhile, considering excessive communication cost low computational efficiency in large-scale power systems, an event-triggered mechanism introduced into Furthermore, order overcome unexpected loss links, time-varying employed develop (DED) algorithm improve robustness. Then, stability above proved by graph theory convergence analysis. Finally, several simulations illustrate that our proposed methods are effective.
