Electricity storage for short-term power system service
The aim of the project is to evaluate and compare – technically and economically – options for using electricity storage to provide short term (seconds to an hour) system services at transmission level in the Danish power system. The project will benchmark potential technologies and give recommendations for a subsequent experimental project phase.

Results
Ancillary services to the power system are likely to become still more important for grid stability as intermittent energy sources penetrate to higher degrees and eventually cover the entire demand. The US Department of Energy has estimated that for every GW of wind power capacity installed in a system, 17 MW of spinning reserves must also be added to account for the system's variability. Crucial properties of storage technologies, which provide ancillary services, are speed, ramp rate and capacity. The speed at which the service can be deployed must at least meet the requirements given by the TSO for the particular synchronous areas, but faster response is an attractive property which can ensure instantaneous balance of load demand and general power.
