København og omegn

Large heat storages are used in district heating systems to balance supply and demand. They also help to provide flexibility to the power system. Power is converted into heat, when there is excess power in the system and then the energy is stored as heat until it is distributed to the customers.
A stratified storage tank is characterized by a warm and a cold fluid layer that are very stable due to the density difference between hot and cold water. Usually, the tank is charged with hot water from the top and the hot water is taken from the top during discharging. However, there are situations were it seems beneficial from a cost perspective to charge the tank from the bottom.
The aim of this project is to identify the effect on the stratification in the tank and the storage efficiency, when being charged from the bottom. To evaluate this a dynamic 2D-model of a stratified storage tank should be build (e.g. in Modelica, Matlab or similar) and validated against measuring data from a system in Nordhavn, Copenhagen.The respective tests are planned for September 2018 and it is possible to join druing the measurements to get an insight into the system.

The project can be started 01.06.2018 or later, an the scope an also be extended for a MSc Thesis.
