Potential and costs for wind power of providing system services to the electricity grid Part 2.

Wind power has excellent ability to supply the electricity grid with the service Fast Frequency Reserve (FFR) by operating the turbines at higher rotor speeds at low winds. The cost of FFR has been quantified to a production loss of 1%.

In this new part, the costs will be calculated as loss of revenues, as the value of electricity varies over time. At the same time, income will be added for FFR.

The control system in the existing generic turbine model of 3.4 MW is further upgraded with market information on compensation levels for electricity production and FFR reserve respectively. Based on these signals, the turbine operation is controlled to maximize the compensation (= system benefit) for the two different services that the wind turbine can offer (energy + power reserve).

The control algorithms will also be implemented and tested on Chalmers' research turbine.
