1. A controller configured to implement coordinated control actions in an electrical power delivery system, the controller comprising:
- a communications interface;
a processor communicatively coupled to the communications interface; and
a non-transitory computer-readable storage medium comprising instructions that, when executed by the processor, enable the controller to;
derive a first state of at least one portion of the electric power delivery system based upon an indication received via the communications interface;
calculate a first controller condition comprising a state of a protective function of the controller;
calculate a proximity of the first state to a possible control action;
generate a component model based on the first state;
model a response of a component of the electrical power delivery system based on the component model;
determine a control action that may be selectively adopted or not adopted from the possible control action, based upon the first state, the proximity of the first state to the possible control action, the modeled response of the component, and the first controller condition;
communicate the first state, the first controller condition, and the control action to a subscribing controller via the network; and
,implementing the control action.

Abstract
Distributed controllers in an electric power delivery system obtain measurements and equipment status, calculate derived values, and determine Intelligent Electronic Device (IED) state, and share such with other distributed controllers and coordination controllers. Distributed controllers and coordination controllers further refine measurements, equipment status, derived values, and IED state. Control of the electric power delivery system is coordinated among the distributed controllers and the coordination controllers.
