Sub-project 6: Electricity supply

Starting point and aim of research

Energy markets are facing severe changes due to an increasing share in renewable energy sources. These changes come along with new challenges in grid stability as well as energy billing. Today’s technical and economical tools do not fulfill all requirements of the highly fluctuating feed-in by renewable energy sources and their absolute priority in energy supply.

In order to balance electricity supply and demand measures such as grid expansion und high volume energy storages are currently being discussed. Another promising option is to adapt the energy demand flexible to the currently available energy supply. This form of demand side management can be achieved by actively including flexible consumers such as manufacturing industries into the power grid.

The object of this sub-project is to analyze the potential in flexible energy demand in comparison to large-scale energy storages. Additionally, regulative policies as an enabler of energy flexible factories are explored.

Approach and methodology

The project starts with a model-based analysis of flexibility required to integrate excess electricity produced from renewable resources. It is supported by a time series analysis.

The second step is to determine the technical potential of different actions to shift the energy consumption in production. It is necessary to analyze how different processes can contribute to the different lengths of changes in energy demand. In addition, it is important to analyze the competition between energy flexibility in production and large-scale energy storage.

The third step is the designing of a regulative environment where it is possible to develop new products for the energy market. These products should provide incentives for the factories to adapt their production. The main question is how to design the products and the markets the products are supposed to be traded on. An agent-based model provides a simulation environment for the testing of new market conditions and products.

In the last step the necessary gateways and data structure for the technical integration of energy flexible factories into the whole system are defined.
