FREQUENCY RESTORATION PRODUCT SPECIFICATIONS (EU / THE NETHERLANDS)


Frequency-restoration

This report presents the results of a study performed to investigate the requirements for and impacts of properties and specifications for balancing products for frequency restoration reserves (FRR) in a representative future power system. The following research questions to be answered in this study were formulated:

  •  What should be the properties and specifications for balancing products for frequency restoration in a system with a high degree of renewable sources that provide adequate frequency quality for the Continental European synchronous power system?
  • How does a selection of properties and specifications for balancing products influence the system costs? To answer the research questions, a two-step approach was taken. First, using a technical model, the adequacy of different balancing products was assessed. Next, selected combinations of specifications on frequency restoration reserves have been evaluated in an economic model of the European power system. This step gives a quantitative analysis on how the reserve requirements impact the operational expenses of the system and the availability and reservation of capacity for power balancing purposes. The operational expenses assessed relate to keeping balancing capacity available for the system. Throughout the course of the project the relation between the different requirements for FRR were considered from a broader perspective which led to the following observations.
