Strong geomagnetic disturbances resulting from solar activity can have a major impact on ground-based infrastructures, such as power grids, pipelines and railway systems. The high voltage transmission network is particularly affected as currents induced by geomagnetic storms, so-called GICs, can severely damage network equipment possibly leading to system collapse. Therefore, increasing attenti...

The large distributed electric power system is a hierarchical network involving the transportation of power from the sources of power generation via an intermediate densely connected transmission network to a large distribution network of end-users at the lowest level of the hierarchy. At each level of the hierarchy (generation/ transmission/ distribution), the system is managed and monitored w...

When the technology of wireless sensor network is applied to ocean monitoring, the ocean underwater monitoring system will become a distributed network system. That could improve the level of ocean monitoring significantly. But most of the current ocean monitoring equipments work independently, and it is difficult to form them into a sensor network. To set up a sensor network, electric energy s...

Light Detection and Ranging (LIDAR) can be used for collecting spatial data of power (transmission) lines providing more accurate geometric information of the power lines and vegetation/object near power electric network. However problem with this kind of data is extraction and classification of raw point cloud data. There is no perfect automatic classification of points, so it is necessary to ...

In power systems, graphical representations of the electric networks are systematically used when designing and operating a network. Being able to visualize the elements of a power system in a two-dimensional space is of paramount importance at these two stages of power system analysis and control. The graphical representation commonly used by all the Transmission System Operators (TSOs) is bas...

using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in this area. in this thesis with using multi-objective evolutionary algorithms nsga-ii and offere...

flexible ac transmission systems (facts) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. in this paper, in order to find type, size and location of facts devices in a power system a dedicated improved particle swarm optimization (dipso) algorithm is developed for de...
