Abstract
Power system economic dispatch with renewable energies like wind power is a typical decision-making problem with uncertainty. Firstly, a robust decision-making model for this type of decision-making problem is formulated in this paper based on the two-person zero sum game, and the detailed robust economic dispatch model for the power system with wind power and plug-in electric vehicles (PEV) is proposed. Further, a relaxation algorithm is adopted to get the optimal solution for the min-max problem. Then, the one hour ahead, ten hours ahead and day ahead economic dispatch simulations on the modified IEEE-9 bus system with wind generators and PEV are carried out and analyzed. And finally the effect of PEVs on smoothing load demand is verified.
