Decentralized Estimation for AGC of Power Systems

چکیده
Abstract: A decentralized state estimation method for automatic generation control (AGC) of interconnected power systems is proposed in this paper. Based on the Inclusion Principle for linear stochastic systems, the state space model of the system is decomposed as a group of pair-wise subsystem models. The overlapping decentralized estimators and fully decentralized estimators are designed for each pair subsystems in the framework of LQG control schemes. Two types of estimators are considered 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.

This paper addresses a new decentralized robust strategy to adapt the well tested classical automatic generation control (AGC) system to the changing environment of power system operation under deregulation based on the bilateral AGC scheme. In each control area, the effect of bilateral contracts is taken into account in a modified traditional dynamical model as a set of new input signals. The ...
