Reliability of Grid Infrastructures
Almost every day, a major electrical failure occurs somewhere in the world within the electrical power grid. The causes vary and can include ageing infrastructure, environmental effects, external interferences (such as animals, projectiles, or moving objects), human error, and in many cases, the inability of equipment to withstand the stresses for which it was designed—such […]

Substation Automation System: The Key Component in Energy Transmission
In recent decades, the growing need for electric power has brought out the need to implement increasingly efficient and reliable automation and protection systems for electrical substations. The development of remote control and tele-conduction functions, which supports remote management plant, has also become a fundamental requirement in the operation of the electricity network. S.A.S. (Substation […]

Photochemical Pollution Modelling In Complex Terrain
Ozone is considered one of the most significant pollutants with respect to the potential impacts to human health and natural ecosystem, both in terms of critical episodes and as long-term exposures. Consequently, in order to assess the comprehensive effects of photochemical pollution, not only ozone peak concentrations need to be examined, but also ozone exposures […]
