1. A method of controlling an energy delivery system, the method comprising:

  • providing an energy management system (EMS) including a wind power management (WPM) system;

    determining sensitivity values for a plurality of wind farms within the energy delivery system using the WPM system;

    maximizing wind power generation from the plurality of wind farms within a set of security limits defined based on the sensitivity values using the WPM system;

    minimizing wind power generation loss from the plurality of wind farms using the WPM system;

    determining wind farm security-priority groups using the WPM system;

    minimizing wind power generation production cost based on cost priority of the wind farms in each security-priority group using the WPM system;

    minimizing wind power generation production cost based on energy bids for each wind farm in each security-priority group using the WPM system;

    conducting a fault analysis to identify which wind farms would trip if a contingency is applied;

    computing a total loss of wind power from those wind farms that would trip; and

    for each of the contingencies, comparing the total loss of wind power to pre-designated wind power loss thresholds for determining a contingency ranking,wherein the contingency may be ranked as a critical contingency, a semi-critical contingency or a non-critical contingency,wherein the critical contingency is that which causes a wind generation loss that is greater than a maximum admissible wind generation loss,wherein the semi-critical contingency is that which causes the wind generation loss that added to a configurable adder constant is greater than the maximum admissible wind generation loss, andwherein the non-critical contingency is that which are neither critical contingencies nor semi-critical contingencies.
