Claim:
1. In a renewable energy system comprising a plurality of renewable energy resources distributed over a geographic area, a method of configuring a renewable energy curtailment and control system comprising: providing a master controller; providing a plurality of controllers configured such that each controller is at a discrete location remote from the master controller and is operative to control one or more of the renewable energy resources; establishing a communication link between the master controller and each of the plurality of controllers, thereby enabling the master controller to receive information from the plurality of controllers and to issue commands to the plurality of controllers; providing the master controller with data comprising predetermined ranges of actual power and reactive power to be delivered to a point of interconnect remote from each discrete location, the data including set points for actual power and reactive power for at least wind turbine renewable energy resources; processing the data and issuing commands to cause the renewable energy resources to provide power such that an aggregate of power from the renewable energy resources is delivered to the point of interconnect within the predetermined ranges of actual power and reactive power; and monitoring active power and reactive power at a plurality of points among the renewable energy resources, and issuing additional commands to the plurality of controllers thereby to reduce flow of reactive power between the renewable energy resources while maintaining active power and reactive power delivered to the point of interconnect within the predetermined ranges.
