Solid State Power Substations for Future Power Grids
2023 IEEE International Conference on Energy Technologies for Future Grids (ETFG), 2023The growing integration of renewable energy sources (RES) is consistently reshaping the power generation mix, while the shift of electricity end-users from customers to prosumers is altering the load patterns. Additionally, as future power grids are expected to include DC resources and DC networks, conventional substations, which are primarily designed

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.

ELF electromagnetic environment in power substations
Bioelectromagnetics, 1989AbstractThis paper presents a theoretical analysis of electromagnetic environments in power substations in service. A new analytical method is developed and applied to magnetic field calculations in 187‐kV and 66‐kV substations. Experimental results verify that the method offers a good prediction of the magnetic field profiles in the substations except

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 ...

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.

Computer vision applications in power substations
2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004Computer vision is a quite mature technology nowadays and it is very useful for power system monitoring applications. In this paper, some computer vision applications in a power substation will be reported. The system implemented is able to conduct automatically intruder detection, fire alarm zone detection and substation meter reading.

Analysis of interconnection substations for sewave power farms
2014 Oceans - St. John's, 2014In this paper we analyse the interconnection of a seawave power farm to the grid. The generator type used in the farm is a linear synchronous generator driven from the seawaves that generates, highly distorted emfs. We presents two possible ways to interconnect the farm to the grid.

Lightning interaction with power substations
2020This chapter presents the influence of lightning on the insulation performance of substation equipment. First, in Section 2.1, the lightning surge analysis including reliability evaluation is positioned in the insulation coordination procedure. As an introductory section of the following ones, the lightning surge analyses are classified in terms of ...
