1. A system for optimal planning of electric power demand, comprising:

  • a node comprising one or more smart charging plug-in electric vehicles (SCPEVs);

    a processing subsystem, wherein the processing subsystem;

    receives system level data, node level data and vehicle level data from one or more sources; and

    determines an optimized SCPEV load and optimal charging schedule for the node by applying at least a mathematical programming technique programming technique on the system level data, node level data and vehicle level data,wherein the node comprises a residential area, a commercial area, or any other area defined by a utility for distribution of electric power, and the node level data comprises load characteristics of the node, wherein the mathematical programming technique comprises;

    dividing the one or more SCPEVs in to one or more groups;

    generating an objective function based upon one or more portions of the system level data, node level data and vehicle level data and determining one or more constraints; and

    optimizing the objective function subject to the one or more constraints to determine the optimized SCPEV load and the optimal charging schedule for the one or more groups.
