Integration of alternative energy sources into digital micro‐grids

Integration of Renewable Energy Sources Using Microgrids, Virtual Power Plants and the Energy Hub Approach

The amount of generation of renewable energy sources in the European grid has strongly increased. In 2005 eight times more energy was generated by RES compared to 1990. In the future the EU wants to promote the integration of RES. Mainly the use of wind energy and biomass should be expanded. As to date, RES were connected to the distribution grid usually with a ”fit and forget” approach. Due to...

Energy Management in Microgrids Containing Electric Vehicles and Renewable ‎Energy Sources Considering Demand Response

Microgrid and smart electrical grids are among the new concepts in power systems that support new technologies within themselves. Electric cars are some advanced technologies that their optimized use can increase grid efficiency. The modern electric cars sometimes, through the necessary infrastructure and proper management, can serve as an energy source to supply grid loads. This study was cond...

Looking for alternative energy sources

With unrest in oil-exporting countries, backlashes against biofuels and photovoltaics, and a nuclear incident in Japan, the year 2011 rattled confidence in future energy supplies. The search for alternatives is all the more urgent, but some of the solutions investigated hark back to fossil fuels that we can't afford to burn.

Optimisation with Integration of Renewable Energy Sources into Energy Supply Chain

Integration of Electric Springs and Multi-Port Transformers—A New Solution for AC Microgrids with Renewable Energy Sources

The new concept of integrating electric springs (ESs) and multi-port transformers (MTPs) as an active solution for energy management in alternating current (AC) microgrids is proposed. With an ES located at the port where storage devices previously were, the so-called critical flux is regulated to a constant value within the core of the transformer. The voltage on each winding is then clamped s...
