Situation Aware Assessment of Regulating Power Need and Resource

Distributed generation and renewable energy sources are both, new disturbance and new regulation resource. Which it is, depends to a large extend on the facilitation of control capabilities, that for example modern wind turbines can provide. Most renewable energy sources are quite unlike classical power plants, but have the capability to provide a number of ancillary services.

It is envisioned that wind power may at times provide a certain share of system stabilization, but it must also be seen that this contribution is limited to only a part of the required functions and that it fluctuates with the available wind. The approach proposed in this paper uses a functional classification to sort out the control requirements of a power system with a high share of fluctuating renewable and distributed energy sources and aims to combine it with a structured quantitative assessment.
