  • Publication number: 20190252886
    Abstract: The present disclosure provides systems and methods for managing an electric power delivery system. The systems and methods may limit generated power of the power delivery system from surpassing a load demand, in order to avoid system instability. The systems and methods may receive an excess generation value and manage generators to runback and/or shed to maintain excess generation below a threshold. The systems and methods may determine a plurality of generator groups for runback. The runback capacity of the generators may be compared against the excess generation. If the excess generation is not greater than the runback capacity, the systems and methods may select generator groups until the runback capacity of the selected groups is greater than the excess generation, and may runback those generators according to runback set points. The unselected generators may continue normal operation to be available for another runback request.

  • Publication number: 20190252883
    Abstract: The present disclosure describes load shedding management systems and methods. A load shedding management system may simulate multiple load shedding actions. Based on the simulations the load shedding management system may select a load shedding action. The load shedding management system may send a signal to trip a set of breakers to implement the load shedding action.
