Short description

Characterizing service provision by power-to-heat units through supervisory controllers.

Present use / development status

Test objective

characterization

Description incl. justification

This test seeks to characterize the impact use of local flexibility has on available regulating power from a local district.

System configuration

This test applies to the generic Nordhavn NHN_001 system configuration (see deliverable D2.3, Appendix D), outlined in Figure B.1. “PCC” denotes the point of common coupling for the district to the various grids.

Use case

System Under Test

All units connected downstream of the respective PCCs must be simulated.

Object Under Investigation

The characterization concerns the Booster Heater Controller and the Electric Storage Controller in combination with the District Supervisory Controller.

Function Under Investigation

Under Joint UC3, the heating system provides services to the electrical system. The test targets an examination of the ability of the system to provide these services. Specific services examined are electrical import and export limitation.

Objective Function / Target Metrics

The comparison is made on the electrical and heat exchange for their given PCC. The test is to be evaluated by the objective function “Trade-offs in heat for power” (see deliverable D4.2, Appendix B.6, page 31), with exogenous prices and relative weights.
Other relevant target metrics include:
• The electrical energy bound violation, separated into the violation on import and export powers  (see deliverable D4.2, Appendix B.1, page 25).
• Total district electricity export (see deliverable D4.2, Appendix B.2, page 25)
• Total district thermal energy import (see deliverable D4.2, Appendix B.3, page 28)
