1. A system for producing a capability region of one or more monitored equipment, the system comprising:
an intelligent electronic device (IED) comprising:
at least one computer-readable medium having instructions to access:
a data set including a plurality of known performance characteristics of the one or more monitored equipment based on a plurality of variables; and
a constraint library comprising a plurality of geometric primitives;
a capability region module that is configured to:
analyze the data set; and
produce the capability region of the one or more monitored equipment by using one or more geometric primitives of the plurality of geometric primitives, wherein the capability region of the one or more monitored equipment comprises one or more constraints;
a response module that is configured to:
determine an operating point of the one or more monitored equipment by using one or more variables of the plurality of variables; and
compare the operating point of the one or more monitored equipment with the capability region of the one or more monitored equipment; and
a control module to implement a control action based on the comparison.
