TL;DR: In this paper, the authors present a concept overview of an automatic operator of electrical networks (AOEN) for real-time alleviation of component overloads and increase of system static loadability, based on state-estimator data only.
Abstract: This paper presents a concept overview of an automatic operator of electrical networks (AOEN) for real-time alleviation of component overloads and increase of system static loadability, based on state-estimator data only. The control used for this purpose is real-power generation rescheduling, although any other control input could fit the new framework. The key performance metrics are the vulnerability index of a generation unit (VIGS) and its sensitivity (SVIGS), accurately computed using a realistic ac power flow incorporating the AGC model (AGC-PF). Transmission overloads, vulnerability indices and their sensitivities with respect to generation control are translated into fuzzy-set notations to formulate, transparently, the relationships between incremental line flows and the active power output of each controllable generator. A fuzzy-rule-based system is formed to select the best controllers, their movement and step-size, so as to minimize the overall vulnerability of the generating system while eliminating overflows. The controller performance is illustrated on the IEEE 39-bus (New England) network and the three-area IEEE-RTS96 network subjected to severe line outage contingencies. A key result is that minimizing the proposed vulnerability metric in real-time results in increased substantial loadability (prevention) in addition to overload elimination (correction).

15 Jun 2001TL;DR: In this paper, power flow management is achieved in an electrical power transmission network using serial impedance modulation distributed throughout the transmission lines of the network, where power flow is managed in at the segments by changing the series impedance of the line by controlling the switching units.
Abstract: Power flow management is achieved in an electrical power transmission network using serial impedance modulation distributed throughout the transmission lines of the network. Switching units are mounted to insulated portions of transmission line towers in proximity to phase lines for modulating power flowing in at least one phase line conductor of at least one bundle conductor phase line in an electric power transmission line at a plurality of segments in the network. Power flow is managed in at the segments by changing the series impedance of the line by controlling the switching units. Enhanced insulation between phase line conductors is added. The power flow in a plurality of electric power lines of the network is analyzed, a desired change in impedance for the electric power lines is determined, and at least some of the switching units are controlled to implement the desired change in impedance.
