Abstract

The renewable energy resources in the Shetland region are considered to be the richest in Europe with capacity factor up to 40%. However, the current Shetland power network which is an islanded 33kV system accommodates only very limited capacity of renewable generation (3.68MW wind farm) due to the network stability issues - one of which is related to frequency. The conventional generation plant at Lerwick power station (LPS) which supplies most of the local demand (11-48MW) is reaching the end of its life, and a more efficient station will be built in the next few years. This research investigates and quantifies the effectiveness of frequency responsive demand side management as an enabling technology for increasing the wind generation levels in the future Shetland power system.
