Power substation supervisory control
Proceedings of IEEE International Conference on Systems, Man and Cybernetics, 2002This paper approaches the utilization of expert system (ES) in operation and control of power substations, within a practical and far-reaching view. Initially, the paper delineates the potential areas and the relevance of utilization of ES as a practical tool in power substation (SE) control and operation.

Algorithm for visualizing substation areas in electric power systems
Expert Systems with Applications, 2022Electric power distribution systems can be represented with mathematical graphs in which the hub nodes are substations which receive electric power from the transmission system and deliver it to the consumers via feeders which consist of transformers, junctions, cables and power lines.

Power supply to distribution substations in wartime
Electrical Engineering, 1942THE purposes of this symposium in relating distribution engineering to the present war emergency have been fully introduced and set forth in the opening paper so that further elaboration will be unnecessary here. As indicated by the title, the discussion in this paper will be confined principally to transmission substations and subtransmission lines ...

Power quality: increasing reliability of power substations
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003In the context of deregulation of the electricity market, a special effort must be made to guarantee a high level of system reliability and supply quality. EDF has developed a tool called TOPASE for characterizing faults in electric power supply, particularly in terms of frequency and duration of power cuts at substations.

A Case Study in Power Substation Network Dynamics
ACM SIGMETRICS Performance Evaluation Review, 2017The modern world is becoming increasingly dependent on computing and communication technology to function, but unfortunately its application and impact on areas such as critical infrastructure and industrial control system (ICS) networks remains to be thoroughly studied. Significant research has been conducted to address the myriad security concerns in

Optimal Power Flow with Substation Reconfiguration
2021 IEEE Madrid PowerTech, 2021Substation reconfiguration may reduce congestion and therefore reduce the cost of economic dispatch. In this paper we propose a novel method that can be applied to any substation configuration using a mixed-integer linear model. Our methodology generalizes substation reconfiguration to include both more traditional transmission switching and bus ...
