• Conclusions
Year 2014Danish wind power generation: 39.1% of the electricity consumption
January 2014Danish wind power generation: 63.3% of the electricity consumption
December 21th 2013Danish wind power generation: 102% of the electricity consumption
Single hour July 9th 2015Danish wind power generation: 140% of the electricity consumption
March 11th 2014only 9 MW wind power generated out of installed 4,900 MW
but 480 MW out of 580 MW solar units supplied the grid

• Conclusions
Heat Pump Model• The dynamics of a direct air heating system can be sufficiently
described by three thermal masses.• The ambient air of the building interior has smaller storage
volume, and defines a faster dynamics of the system.• the larger storage volume of the building envelope, or structure,
describes a slower dynamics of the system

• Conclusions
• The DFR technology has been developed to utilize the demandside resources to provide fast reserves needed in the futurerenewable based power system.
• The DFR technology has been tested by offline simulations in theprevious work.
• The real time HIL tests were conducted to verify the effectivenessof the DFR technology.
• The HIL test results show that the DFR technology cansuccessfully arrest the system frequency and illustrate the efficacyof the SmartBox.
