Abstract: A hybrid power plant including a plurality of power sources and controllers, a hybrid plant controller, and a computing system. The controllers operate the power sources according to operating set points. The hybrid plant controller transmits the operating set points to the controllers. The computing system is coupled to the hybrid plant controller and receives a first set of input parameters from a first subscriber, and carries out a first level of services to which the first subscriber subscribes to determine operating parameters for the first subscriber. The computing system receives a second set of input parameters from a second subscriber and carries out a second level of services to which the second subscriber subscribes to determine operating parameters for the second subscriber. The computing system then computes the operating set points based on aggregate operating parameters for the first and second subscribers.
