FUZZY STATE PREDICTION FOR POWER SYSTEMS

This paper presents a new approach to power system state prediction based on the application of fuzzy logic. The fuzzy predictor uses the past (priori) estimated states and measurements vectors as entrance parameters,and it infers the next estimated states. The design of the fuzzy redictor is described. The results shows how the fuzzy predictor simultaneously detects and rejects bad data while obtaining an accurate predict of the state. The approach is illustrated for two sample systems:a 30 - bus and a 57 - bus system.
