Introduction Solar energy is inexhaustible. The amount of solar irradiation that reaches the Earth’s surface is tremendous: approximately 10,000 times more than the current humanity’s energy needs for a whole year [1]. Besides solar power, many other forms of renewable energy such as wind energy, hydropower and biomass depend on the Sun. Wind, used by…

Synchronization in dynamical systems and power systems
Synchronization - a fundamental concept Synchronization is a fascinating and fundamental physical phenomenon found in many different systems with vastly different sizes. It can be found in mechanical, biological or chemical systems as well as human behavior or human made structures, for example in power systems. The first observation and description of synchronization was made…

Microgrids, a game changer
In the coming years, the Energy sector will change completely its paradigm. It is already happening due to the disruption of the ICT technologies, the cost reduction of the renewable energy sources (RES), energy storage systems (ESS) and other grid devices which make the grid smarter, in other words, more controllable and more observable. One…

Faults and power grids
Electric energy is one of the most remarkable resources of modern society. From the consumers’ side, electricity is available instantaneously, exactly in the amount required, and at the requested voltage and frequency. To achieve this very high level of performance, a very complex network composed of generators, transformers, and transmission and distribution lines is carefully…
