Abstract
In this paper, a power system set membership state estimator (SMSE) in a bounded-error context is proposed based on interval constraint propagation. Its effectiveness is tested with the IEEE 4-bus, 14-bus, 30-bus, 118-bus, and 300-bus systems. Comparison is made between SMSE and typical existing methods. Simulation results show that the proposed method is effective in obtaining a guaranteed and small envelop of the state and measurement and is also time efficient.
