Project description

The current political and ecological underlying conditions combined with continuously increasing energy prices require not only the utilisation of all options for generating environmentally friendly energy but also further energy savings. As a consequence of the development of renewable energy, in particular for generating electrical energy, generation solutions will be required in future that can react very quickly to fluctuating loads.

The aim of the project is to develop and analyse an active load and generation management system for electrical and thermal energy forms with a focus on decentralised generation structures as well as decentralised plant- and building-related thermal storage systems in the urban environment. In addition to supplying heat to individual buildings, a particular focus will be on inter-real estate connections to local heating networks.

Project structure

Various scientific facilities are cooperating as part of the project with the aim of achieving a coordinated energy management system for buildings and neighbourhoods. The project is divided into 5 sub-themes (ST), which are being processed as follows:

  • ST1: Energy management in buildings
    Professorship for building energy technology and heating provision
  • ST2: Energy management of district heating networks
    Professorship for building energy technology and heating supplies
  • ST3: Storage ability of the building structure
    Professorship for building climatology
  • ST4: Storage potential outside of buildings
    Professorship for construction management
  • ST5: Modelling electrical networks
    Professorship for electrical energy provision.

In addition to developing analysis tools in the form of numeric programs, the findings will be tested out in selected example systems. In addition to the thermal and hydraulic analyses, an electrical network is being modelled for the supply area under consideration and the impacts on the developed control and optimisation strategies will be discussed.

Objective

In addition to developing optimised regulation and control concepts for operating complex energy systems, the thermal storage potential within and outside of building envelopes will be quantified and assessed in terms of energy and economic aspects. In conjunction with the use of small, decentralised CHP systems, this will provide information about the electrical frequency stability and voltage quality.

Work plan

To conduct the research programme, an interdisciplinary research group has been set up at TU Dresden that comprises scientists from the construction, building energy technology, thermal provision and electrical energy provision sectors. Techem Energy Services and Vattenfall Europe are also supporting the project.

The research work encompasses:

  1. Detailed literature research, definition of interfaces
  2. Measurement-based experimental test rigs
  3. Conducting stationary and dynamic investigations as a basis for producing numerical simulation models.
  4. Modelling of plant components, building models and neighbourhoods
  5. Implementing simulations in the form of variant calculations
Financing

The project is being funded by the German Federal Ministry of Economics and Technology as part of the EnEff:Stadt research initiative’s joint "Network" project, whereby 16.5% of the expenses are being paid for from funding supplied by industrial partners.
