Ancillary services from renewable power plants

Project Details

Description

RePlan project is a frontrunner for the integration of large share of renewable energy in the Danish power system. RePlan aims at rethinking the way of using renewable generation resources, as it focuses on enabling a resilient power system by providing ancillary services in a jointly coordinated manner.
The overall objective of this project is to contribute to the integration of large share of renewable energy in the Danish power system and thus to enable a resilient power system in the future by developing technical solutions for the provision of ancillary services by renewable power plants. RePlan focuses on WP and PV plants since they are expected to jointly produce the lion’s share of renewable energy generation capacity needed to reach the Danish government 2050 targets.
With respect to renewable generation (ReGen) plants, investigation of ancillary services, coordinated control, fast communication and forecast of available power are crucial step stones on the route toward a future resilient power system. The ability to provide ancillary services from ReGen plants depends on the communication and the forecast of availability power. In this respect, RePlan develops controllers for the delivery of ancillary services, incorporating communication properties in the control loops of the ReGen plant model and using state-of-the-art methods for simulation of renewable generation patterns and wind power forecast methods. Based on both simulation models and verification in laboratory facilities, this project intends to address this challenge: What is the impact of communication and power availability forecast error in providing coordination and ancillary services from ReGen plants?
The novelty of RePlan consists in the investigation and verification of the ancillary services provision from wind and photovoltaic power plants and of the suitability to coordinate their services provision to power system operator. In this respect, RePlan strives to identify and analyze the strengths and limitations of WP and PV plants, anticipating new challenges and exploring some of the more complex issues and uncertainties related to the coordination of their ancillary services. The services with great concerns in the future include: voltage, frequency and rotor angular stability support.
