1. A controller configured to balance electrical generation and electrical demand in an electrical power system, the controller comprising:

  • a user parameters subsystem configured to receive;

    a plurality of priority designations associated with a plurality of loads; and

    an inertia of a plurality of electrical generators;

    a trigger event analysis subsystem configured to detect a first trigger event based on electrical conditions at a plurality of nodes within the electrical power system, each node comprising an electrical generator;

    a topology detection subsystem configured to;

    identify a first subset of the plurality of nodes at which electrical conditions reflect the first trigger event;

    associate in an electrical island a subset of the plurality of electrical generators and a subset of the plurality of loads based on the first subset of the plurality of nodes at which the operating conditions reflect the first trigger event;

    an electrical balancing subsystem configured to determine an imbalance between electrical generation and electrical demand in the first island based on a combined inertia of the subset of the plurality of electrical generators and the electrical demand of the subset of the plurality of loads;

    a control action subsystem configured to generate a control action operable to eliminate the imbalance between electrical generation and electrical demand based on the combined inertia of the subset of the plurality of electrical generators and the plurality of priority designations associated with the subset of the plurality of loads.
