The construction of an intelligent battery charging and swapping network，which includes centralized charging stations，battery charging and swapping stations，battery distribution stations and charging spots，is considered as a reasonable business model to cope with the popularization of electric vehicles in densely inhabited districts.In electricity market environment，the uncertainty of electricity prices may have significant impacts on the decision-making process of the centralized charging station.In order to formulate a coordinated charging strategy and determine the proper frequency regulation capacity in each trading hour of the day-ahead market，the dispatching ratio of the contracted frequency regulation capacity and the battery degradation cost are first analyzed.In the framework of the centralized charging and unified distribution battery swapping mode，novel robust optimization models for both unidirectional and bidirectional energy transfer modes are then presented respectively to solve the coordinated dispatching problem of the centralized charging station with the market price uncertainties considered.Afterwards，the highly efficient commercial solver developed by the IBM Corporation，namely CPLEX12.2，is employed to solve the developed robust optimization model.Finally，a test system of a centralized charging station，providing charging services to eight affiliated battery distribution stations，is employed to illustrate the basic characteristics of the presented model and solving method.
