Solar flares in Shanghai

Space weather, specifically Solar super storms can wreak havoc on modern infrastructure. The impacts of the resulting geomagnetic superstorms are known in the electrical engineering community, but have since their discovery been systematically underestimated for equatorial latitudes. New insights imply the risk and impact on these regions are equal to the impact in polar regions and consist of; ionosphere saturation and geomagnetic fluctuations. These, when poorly managed or unexpected, will lead to loss of wireless communication capabilities and a breakdown of the power grid. These impacts and their planned preventions, as well as possible complications via cascading failure are laid out in this paper. In conclusion, very little can be said about Shanghai as the information is seen as of strategically value and thus is kept confidential. Initial damaged are partially avoidable, but long term impact will be unprecedented in the modern world.

Second of the 4 A's: Availability

In this module we will discuss the concept of Availability. In module 2 we have learned that 1 billion people still lack access tot electricity services. But what if they do? Does that mean that all their problems are solved? Unfortunately not. Worldwide, there are plenty of examples where people do have access, but powercuts occur so often, that people still cannot always rely on the grid. Also, when becoming more dependent on renewable energy sources such as solar and wind, what happens when there is hardly any sun, or hardly any wind? These questions, among others, will be addressed in this module. Outline: The structure of this module consists of two parts: The theory track. After the introduction video there will be video’s on quality of supply, the availability of energy in a smart grid and dimensions of availability. The case track. This module’s case is on the North Sea Wind Power Hub, where multiple organisations and countries work together to improve the off-shore wind farms.
