First Claim
1. A method comprising:
- providing a model for a predetermined location within an electrical power system having therein distributed resources (DR), the model based on known system conditions, the model indicative of first sensed characteristics of the electrical power system at the predetermined location;
sensing at the predetermined location characteristics of the electrical power system corresponding to at least some of the first sensed characteristics;
determining a status of the electrical power system network indicative of an islanding event in dependence upon sensing and other than in dependence upon other sensed data sensed remotely from the predetermined location; and
,controlling a distributed resource in dependence upon the status.
