Energibranschens förutsättningar och förväntningar
The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large …
… objekt inom svensk infrastruktur. Speciellt intresse ägnas åt Snake Grid-projektionen som utvecklats av University College London i samarbete med Network Rail, som bygger och underhåller det brittiska järnvägsnätet. I samband med att man i Sverige satsar på utbyggnad och …
As a part of Göteborg Energi’s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the …
Bidraget till minskade förluster
… the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency …
Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as …
