The role of Swedish wind energy storage system

Can large capacity wind power be installed in Sweden?

Olauson et al. did a sophisticated study on wind power scenarios in Sweden and the time series analysis for future wind power productions. It is simulated and found that large capacity wind power can be installed within a wide area and offshore in Sweden.

How can hydropower and wind power work together in Sweden?

Coordinating hydropower and wind power satisfies hourly operation requirement. Swedish government’s target is to have 100% renewable electricity production by 2040. Currently, hydropower contributes the majority of renewable electricity generation of the country. The wind power capacity has increased significantly in the past decade.

What is the capacity factor of wind power in Sweden?

Due to the restricted availability of wind power and its fluctuations, capacity factor of wind power is low, between 20% and 35%, depending on locations, wind resources, turbines, etc. The existing wind power capacity for Sweden (2014) is 6038 MW, and capacity factor is 0.22.

Can wind power replace nuclear power plants in Sweden?

Zhong et al. investigated the current status of the electricity sector in Sweden to explore the feasibility of replacing nuclear and conventional thermal power plants with wind power. The results indicated that such a replacement is possible by increasing the capacity of wind power to three times the current levels with pumped hydro storage .

How can a 100% renewable electricity system be achieved in Sweden?

A 100% renewable electricity system in Sweden can be achieved by using wind power generation to fill the gap between electricity consumption and hydropower generation. The total electricity consumption of 2014 in Sweden was 129.83 TWh, and total hydropower generation was 65.01 TWh.

How much wind power does Sweden produce in a year?

The existing wind power capacity for Sweden (2014) is 6038 MW, and capacity factor is 0.22. This means the total generation from wind power in one year is around 11.6 TWh, which is calculated by E t o t a l = C F × P M a x × T = 0.22 × 6038 MW × 8760 h. Capacity factors of off-shore wind farms are usually higher than for on-shore wind farms.
