Provision of enhanced ancillary services from wind power plants – Examples and challenges


Power system impact of WPPs’ capability to provide TFR and POD is investigated.

WPPs can provide TFR and POD to enhance the stability of power systems.

The need for coordination between WPPs in TFR and POD provision is emphasized.

Simultaneous TFR and POD provision from multiple WPPs should not be stated as requirement without thorough analyses.


Emphasis in this article is on the power system impact of wind power plants capability to provide enhanced ancillary services, i.e. temporary frequency response (TFR) and power oscillation damping (POD). The main objective of the article is to analyze and justify the challenges in the use of TFR and POD from wind power plants (WPPs). The study is conducted with an aggregated wind power plant model which is integrated into a generic power system model, specifically designed to assess the targeted ancillary services in a relatively simple, but still relevant environment. Various case studies with different wind power penetration levels are considered.

The study shows that WPPs can provide additional control features such as TFR and POD to enhance the stability of power systems with large share of wind power. Nevertheless, the results illustrate that the power system stability can be potentially degraded without careful coordination between WPPs, simultaneously providing TFR or POD in power systems with large displacement of conventional power plants by WPPs. The article provides to TSO new insights into the need for service coordination between WPPs into future power systems.
