The share of renewable energy sources in the electricity generation is expected to maintain a steady growth in the future driven by economic and environmental reasons. However, these renewable sources such as wind and solar have fluctuating power output. This fluctuation causes strain on the power system and can cause imbalances between...

There is a rapid increase in the off-shore wind farms and the interconnection between countries which results in an increased energy transfer over longer distances. High voltage DC (HVDC) cables can transfer this energy in a reduced cost and efficient way in contrast with high voltage AC (HVAC) along with many other benefits. For the HVDC cables...

Wind constitutes a dominant form of sustainable energy that is expected to grow rapidly in the years to come. Increased inverter-based wind power penetration may however endanger grid stability and reliability, if not enriched with the capability to provide crucial ancillary services to the grid, such as frequency regulation. In order for the...

The accuracy of modelling distribution networks plays a very important role in analysing the stability of transmission systems. In recent years, due to the surge in the integration of renewable energy resources via power electronic interfaces, distribution networks are evolving from passive networks to modern active networks. This means that...

Increasing wind generation causes displacement of conventional power plants with Synchronous Generators in electrical power systems. This condition leads to less inertia, less controllability and a degraded damping performance in the electrical systems. Studies of stability of the power system attempt to analyze this issues. Rotor angle...

There are two existing surface passivation principles. Passivation of unsaturated Si bonds is called chemical passivation. Surface passivation can also be achieved by shielding the minority charge carriers from the semiconductor interface by means of an electric field. This method is referred to as field-effect passivation. <br/>To test the...

As the primary protection of high voltage (HV) and Extra high voltage (EHV) transmission networks, distance protection needs to operate properly under all possible fault conditions. It needs to operate as fast as possible for internal fault, while it also must be able to discriminate between the internal and the external faults to prevent...
