Interdisciplinary research for sustainable and stable grid operation

"Smart Nord“ research group, Lower Saxony
The future electricity supply system will be characterised by large numbers of decentralised producers and storage units in distribution grids. In addition to coordinating power balance, these systems will have to contribute to critical system tasks, especially regarding frequency and voltage control. Currently, these tasks are handled by conventional power plants. The challenges of a continuous substitution of conventional power plants with distributed energy resources are subject to methodical research and development within the Smart Nord interdisciplinary research group. The main objective is to achieve a stable grid operation in future power systems.

“Smart Nord – Smart Grids in Northern Germany” is an interdisciplinary research group comprising four universities and three research institutes. It is funded by the Lower Saxony Ministry for Science and Culture. The objective is to contribute to a coordinated and decentralised supply of active power, control power and reactive power in the distribution grids. An ICT infrastructure including all of the components is a prerequisite for this purpose. The infrastructure relies on agent-based, self-organised control systems and takes security aspects and component interoperability into account. Particular attention is paid to the dynamic aggregation of decentralised consumers, producers and storage systems for a schedule-based provision of active power and ancillary services. The power grid itself is subject to analyses regarding the frequency and voltage stability of these new operating modes. These analyses comprise both the European transmission grid as well as possible microgrid operations. In addition, a spatial feasibility assessment for the potential of renewable energy systems especially in Lower Saxony is carried out.

Smart Nord is divided into six sub-projects:

1. Active power supply in distribution networks by means of decentralised, dynamically formed clusters of energy systems

2. Methods for a guaranteed supply of ancillary services that support grid operation in real time and are based on decentralised producers with uncertain behaviour

3. Development of an integrated energy market for the purpose of trading both active power and ancillary services

4. Investigation if the potential of decentralised supply units within the distribution grids for power plant functions in the overall system

5. System theory and optimisation for inverter-dominated distribution grids through the inclusion of stochastic producers and consumers

6. Methods for spatial feasibility assessments of renewable energy and their impact on landscape functions and ecosystem services.
