Controlling the power balance in an 'empty network'
This paper presents the concept of an 'empty network' and shows how the power balance can be controlled in such a system. In this study, an 'empty network' is defined as a transmission system in which no rotating mass is present. All generators are connected to distributed systems and 'hidden' behind power electronic interfaces. One generator creates a neat 50 Hz voltage that serves as a ...

Optimal control of matrix converter based WECS for performance and stability enhancement at low wind speeds
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal ...

When Disaster Response Drives Transformational Change to Grids, Fuel Cells are the Preferred Choice of Many Energy Prosumers
The increasing frequency of weather-related disasters puts emergency disaster response in the headlines often and encourages more and more systematic solutions. In the example of wildfires in the U.S., where 30,000 fires burned over 3.5 million acres between January – August 2019, systematic solutions are crucial. Seeking to minimize fire damage, utilities in California have instilled the ...

Trends in the Energy Sector Digitalisation
As the intensifying debate around climate change amplifies, the energy sector is continuing its trend toward phasing out fossil fuels and moving towards reliance on renewable energy. The American Energy Information Administration (EIA) has reported that it expects about 65 GW of coal power to be retired between now and 2030 and that nearly 90 GW has already been phased out since 2011. The latest ...
