Research Project kurSyV

More efficient use of electricity grids through curative system management

Curative system management makes it possible to make better use of the existing grid infrastructure and reduce the measures required to eliminate bottlenecks. This is an innovative approach in which interventions are only carried out after the occurrence of predefined faults and thermal reserves are used. This represents a fundamental change in the way electricity grids are operated and poses numerous practical and technological challenges due to its complexity.

Background and developments to date

Initial investigations into the possibilities of curative system management, particularly with regard to the transmission grid, were carried out as part of the "InnoSys 2030" project. Since the start of this project, however, the pace of change in the energy system has continued to accelerate. In particular, the feed-in of electricity from renewable energy sources such as wind and solar energy into the distribution grids has increased significantly. Despite measures already planned and long-term grid expansion, these distribution grids could become a bottleneck factor.

kurSyV project: Curative system management in the distribution grid

The kurSyV project has set itself the goal of extending curative system management to the 110 kV distribution grid. The aim is to examine how the advantages of this innovative mode of operation can also be used within the distribution grid, along with creating the possibility of higher capacity utilization whilst ensuring grid security. As a result, more renewable energy sources can be integrated into the existing grid in the short term and the necessary grid expansion can be delayed.

Practical implementation and development of new concepts

As part of kurSyV, specific measures are being developed to implement curative system management in the 110 kV distribution grid. The aim is to develop practicable concepts for both the grid and the systems involved. An additional aspect of great importance would be the development of incentive systems that enable operators of renewable energy plants to put their flexibility at the service of curative system management. The focus here is on the creation of concrete sample solutions along with the necessary adjustments needed to integrate these into grid operation.

Analysis and practical relevance

The solutions developed in the project will be tested for their practical suitability, effectiveness and relevance during the course of the project. In this way, kurSyV should make an active contribution to improving grid capacity utilization and further promoting the integration of renewable energies.
