Project description

The research project includes the measurement-based analysis of mini- and micro-CHP systems, numerical investigations of the systems in the network, a field test phase as well as the creation and optimisation of a superordinate control regime with the inclusion of the power exchange.

Objectives

The research project aimed at calculating and optimising complex energy supply structures on the electrical and thermal sides. Particular attention was paid to the different reaction times of the subsystems. In addition to CO2 savings, it was also intended to investigate the possibilities and limitations of micro-CHP systems in the building sector. The development, testing and optimisation of appropriate control strategies for micro-CHP systems are also intended to support their establishment in the market.

Work programme

The research work encompasses:

  • Measurement-based analyses at a laboratory scale
  • The development of a "hardware in the loop" environment
  • Dynamic investigations and the creation of numeric simulation models
  • Conducting such simulations in the form of variant calculations
  • as well as a field test
Funding

In addition to the project funding provided by the German Federal Ministry for Economic Affairs and Energy as part of the EnEff:Wärme research initiative, another quarter of the expenses was met by industrial partners.

Preliminary steps, findings

In the first step of the processing, new thermal and electrical test rigs were built. These were integrated together to form the "Combined Energy Lab". This experimental arrangement is currently being used to run extensive analyses concerned with basic research. A field test is also currently being prepared. The selected test objects were equipped with appropriate measurement technology.

The investigations have produced detailed measurements of the CHP devices in the laboratory. The test rigs and their commissioning have been described in detail. The final report also documents a field test that was monitored by the participating institutions during the research project. Different simulation tools have been developed to simulate a regional virtual power plant (RVPP). This was used to carry out numerous numerical simulations that focussed on controlling RVPPs and optimising the control engineering.
