1. A method comprising:
deriving a first circuit diagram representing a steady state sequence network by a computing device;
receiving an indication of an unbalanced condition in the steady state sequence network by the computing device;
in response to the indication of the unbalanced condition, converting the first circuit diagram to a second circuit diagram comprising impedances in the Laplace domain by the computing device;
performing a system analysis of the second circuit diagram using the unbalanced condition to determine if the unbalanced condition may result in a loss of stability for a power grid by the computing device; and
in response to determining that the unbalanced condition may result in a loss of stability, generating an alert that the unbalanced condition may result in the loss of stability by the computing device.
