Distributed electric vehicles cooperative charge control with wind power

Load dispatch such as electric vehicles (EVs) is considered as a promising approach to promote the integration of wind power. In this paper, a distributed framework is proposed to coordinate a large number of EVs with wind power based on stochastic dual programming theory. Lagrangian Relaxation (LR) and Auxiliary Problem principle are adopted in the problem decomposition. Compared with existing distributed methods, the proposed method gains an advantage in minimizing generation cost and is proper for masses of EVs. In addition, it can depose of non-convex problems with coupling constraints and it is with larger applications. The method is verified feasible and valid by the case study on IEEE-RTS.
