Description

In this presentation the topic of sector coupling is discussed with a specific focus on utilising extra profits for the operation of an existing 5th generation district heating and cooling network (5GDHC) in Zürich, Switzerland. It was investigated, how the heat energy production through large industrial heat pumps and the total heat capacities of the 5GDHC system can provide flexibilities for power to heat applications. The intention was to take advantage of the European electricity day ahead market or provide grid stabilisation services to the electricity balancing market of the respective country to obtain a lower heat energy retail price for the customers of the 5GDHC network. Therefor in a first step the special requirements of a 5GDHC system were implemented into a previously developed co-simulation tool for large district heating systems. Followed by the modelling of the investigated network using the tool IDA ICE. In a second step the system flexibilities were systematically investigated with respect to key performance indicators like heat capacity, response behaviour or electrical energy consumption as a function of the thermal comfort in the connected buildings. It was also investigated, how a sliding average control strategy using the electricity price signal and the indoor room tempertare can contribute to utilising extra profits for the network.
