Control of Large Power Systems Based on Situation Recognition and High Speed Simulation

The operation of large power systems places an increasing importance on the security of the system which must be evaluated in steady state, transient, and long term dynamic situations. A method based on "situation recognition" and high speed simulation for on-line security computations is proposed and analyzed. The method combines the advantages of high speed hybrid computer simulation and pattern recognition methods, and, at the same time, has the flexibility of a pure digital simulation.
