- Abstract
- In Sweden the installed wind power has increased rapidly in recent years and the trend looks to continue. New law, in which Svenska Kraftnät will lend investment capital for expansion of grid capacity to renewable energy, will facilitate the connection of wind power plants to E.ON’s regional grid network. With more wind power connected to the grid network losses will look different.In this report, the losses in the electricity grid in eastern Småland and E.ON’s subtransmission grid have been studied. It has been done such that new installed wind power has progressively increased up to 100 % of installed power capacity in the simulation model for eastern Småland in PSS/E.

- In Sweden the installed wind power has increased rapidly in recent years and the trend looks to continue. New law, in which Svenska Kraftnät will lend investment capital for expansion of grid capacity to renewable energy, will facilitate the connection of wind power plants to E.ON’s regional grid network. With more wind power connected to the grid network losses will look different.In this report, the losses in the electricity grid in eastern Småland and E.ON’s subtransmission grid have been studied. It has been done such that new installed wind power has progressively increased up to 100 % of installed power capacity in the simulation model for eastern Småland in PSS/E. System load for a whole year was divided into eight load ranges where simulation were made with increased new installed wind power for each load range.
The results show that when the installed wind power in eastern Småland increases, so will the energy losses in the grid, even for E.ON’s regional power grid. The most crucial issues for the energy losses are the system load and the number of hours the load lasts.
Also the placing of the wind power plants in eastern Småland affected the losses. As the installed wind power was substantial in relation to the load, the power was transmitted further out on the grid. From that the wind power first contributed to reduced power on the lines, so increased the power again when the installed wind power increased.
The existing installed wind power in E.ON’s regional grid today contributes to reduce grid losses. For wind energy production 2013 the producing wind power could be increased by 80 % and still contribute to reduced losses. This suggests that the placement of the wind power
today is optimum out of loss standpoint.
Investing in new high temperature, low sag (HTLS) conductors to reduce power grid losses in eastern Småland is not economically viable at present. Thought losses are reduces by 10 – 30 % for HTLS conductors compared to corresponding ASCR-conductors, so will the total
contribution to power losses over the year be very little.
New incentives, including increased use of the power grid and reduced losses, may affect the revenue cap limit for power grid companies. But at the same time increase the utilization of the power grid capacity and reducing power grid losses, is contradictory as increased utilization of the grid capacity results in increased power grid losses.
