Enable robust smart grid control utilizing heterogeneous third-party communication infrastructures
Challenges
Variable communication network performance– caused by variable traffic load and
accidental faults
– affecting quality of input data and timeliness of control actions
Security threats– due to additional network
interfaces and
– the use of off-the-shelf communication technology

IFIV: Remote control of heat pumps for smart grid purposes
Purpose: to move consumption according to wind power production.
Elspot prices and wind power production correlates.
Balance Responsible Party (BRP) optimize Elspot purchase based on•Elspot price estimates•Weather forecast•House parameters
The BRP controls the individual heat pumps. For each hour an amount of energy is bought in advance. Each house is controlled by the VPP in order keep the house temperature within a predefined band using the bought energy.The VPP calculates the possible regulating power each hour.
Results
Tested on 6 inhabited single family houses.Results for one house 18-19 April 2012 is shown.Spot plan power is the purchased energy for the house.Active plan power is the real time control signal to the house.Heat pump power is measured power from the heat pump.
It is seen that the active plan is approximately the same as the spot plan power.The room temperature is within the comfort bounds.A low threshold value on the heated water tank temperature forces additional heat pump starts.

Smart & Cool: Adaptive balancing of consumption in supermarkets
The overall goal of the project is to allow an increase in penetration of wind energy in the power grid. This will be realized by the optimal distribution of consumption in refrigeration systems and electricity production.
