摘要：

Based on the Inclusion Principle for linear stochastic systems, a decentralized state estimation methodology for automatic generation control (AGC) of the multi-area overlapping interconnected power system is proposed in this paper. The overlapping decentralized estimators designed in the framework of LQG control schemes are applied to the system decomposed as a group of pair-wise subsystems. For area autonomous control, the estimators of subsystem interconnections described by the tie-line power are fully decentralized in each pair subsystems. Two types of estimators are designed for the cases of full and reduced measurement sets in the framework of system closed-loop operations. Simulation results show a high quality of the AGC scheme based on dynamic controllers with the proposed state estimators.
