Power plants experience distinct dynamic behaviors according to the primary source of energy. Whereas thermal power plants have a slow dynamic, modern renewables such as wind and solar PV are subject to very fast variations, due to environmental factors. T ...
There has been an evolving electricity market structure starting from the spot market and its derivatives, to several other markets such as the Intraday Market, the Balancing Market and the Reserve Capacity Market. The participation in these markets has ch ...
The global emission of CO2 has increased in the sector of power generation from countries outside the OECD, particularly in China which comprises two-third of the share. Meanwhile, OECD countries focus their effort in reducing their emission, where the ind ...
This paper deals with a power management mechanism using Modular Multilevel Converter (MMC) with integrated energy storage elements, the typical use of which could be a grid-interface for a photovoltaic park or a charging park for electric vehicles. In com ...
In Switzerland, the government has made ambitious plans for a major energy transition. There is a planned phase out of nuclear facilities by mid-century, their capacity replaced by an expansion of hydroelectric infrastructure, new geothermal installations, ...
The security of supply is becoming an important concern in the energy supply of the railway networks operated at 16.7âHz. This situation calls for the improvement of the interconnection with the 50âHz grid and creates a need for ancillary services, esp ...
Ancillary services constitute the cornerstone of the power grid. They allow for an efficient system operation, provide resilience to uncertainties and establish safeguards against unprecedented events. Their importance is growing due to the rise of grid de ...
Development of intermittent solar and wind energies and the demand peak increase has made energy storage very important in energy policy. Thus, energy storage will play a key role in enabling the world to develop a low-carbon electricity system. An interes ...
Decentralized generation, distributed energy storage systems and active participation of end-users in the lower level of the electrical infrastructure, intelligently managed to provide grid support, define the notion of Active Distribution Networks (ADNs). ...
This paper reports the design, fabrication, and testing of a soft dielectric elastomer power generator with a volume of less than 1 cm3. The generator is well suited to harvest energy from ambient and from human body motion as it can harvest from low frequ ...
