Résumé

The integration of wind power into the national or EU energy supply systems is becoming more problematic with increasing installed capacity and production, due to a mismatch of supply and demand of energy. The wind energy is produced at random times, whereas the energy use pattern shows distinct demand peaks during daytime and office hours, and low levels during the night. To use a refrigerated warehouse as a giant battery for wind energy will provide economical benefits from the cost difference between low and peak hour electricity prices. It can also assist in levelling out undesired peaks on the electrical grid. Storage of energy in cold stores is done by producing more cold than necessary - thus lowering product temperatures. The virtual release of energy arises from the difference between average cold store demand and zero demand {with product temperatures rising to the original value). The Night Wind project will manage with existing technology and will develop new control strategies and control concepts that will set the temperature level in cold stores, taking into account economical aspects (derived from the actual balance between wind energy production and actual electricity demand), technical aspects and limits derived from food quality aspects.
