Ancillary services from renewable power plants - Final report RePlan

Modern ReGen plants can provide the distribution and transmission network with useful ancillary services, such as voltage and frequency control. The RePlan project has defined ReGen plant level control algorithms, modelled and simulated their technical performance, and tested them in a Real-Time Hardware-in-the-Loop (HIL) environment based on multi-domain physical systems or in a real small scale power system, namely the SYSLAB facility existing at the DTU Risø Campus. RePlan has developed and evaluated 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. Guidelines and recommendations for practical implementation of the developed control algorithms for targeted ancillary services have been defined. The technical ability is clear. The scientific contribution and industrial relevance is satisfactory. The continuation is straightforward, if commercial prospects prove their incentive.
