Predicting steady-state instability

The ability to know how much load can be met and how much power can be sold while maintaining a safe distance from the point of voltage collapse and steady-state instability is of great concern both in the real-time dispatch and during the operations planning and scheduling activities of power systems. This is particularly true in an increasingly deregulated electric utility industry where power systems are, and will be, dispatched within smaller voltage and steady-state stability margins than in the past. The authors describe a new application of REI-Dimo techniques which targets power system operation close to the maximum power transfer capability while maintaining a safe distance from critical states.<
