Testing of curative relief measures in extra-high and high-voltage networks

Berlin, August 12, 2022 - PSI Software AG, as consortium leader in the joint research project PROGRESS, is testing curative measures for decongestion in extra-high and high-voltage networks together with six other joint partners. The project is funded under 03EI4046A as part of the 7th Energy Research Program in the area of "Electricity Networks" of the German Federal Ministry of Economics and Climate Protection (BMWK).

The project objective is the practical testing of curative grid management in extra-high and high-voltage grids. In this context, curative measures correspond to a reactive adjustment of actuators in the network for the targeted influencing of voltages and currents after the actual occurrence of a fault. The existing network can thus be utilized to a higher and more efficient extent and the share of preventive measures in congestion management can be reduced.

The goal of PSI is the development of prototypical applications for curative grid operation management and their field testing in the grid areas of TenneT TSO GmbH, Transnet BW GmbH and Schleswig-Holstein Netz AG. In field test I (transmission system operator/transmission system operator), the focus of PSI is on the prototypical testing of a module for the online determination of limit values and their cross-network operator coordination. Furthermore, the further determination of curative measures and their validation by dynamic network analyses is considered in the project.

In field test II (transmission system operators/distribution system operators), PSI will test individual functional prototypes on the TSO side, which will pilot the data exchange between the network operators and the activation of curative measures. In addition to PSI Software AG, the six joint partners include TenneT TSO GmbH, Transnet BW GmbH, Schleswig-Holstein Netz AG, RWTH Aachen University (Institute for Electrical Systems and Networks, Digitalization and Energy Economics), Otto von Guericke University Magdeburg (Institute for Electrical Energy Systems) and Netze BW GmbH as an associated partner.

The project started on May 1, 2022 and runs until October 31, 2025.

The PSI Group develops its own software products for optimizing the flow of energy and materials for utilities (energy grids, energy trading, public transport) and industry (metals production, automotive, mechanical engineering, logistics). The industry-specific products, which are built from standard components, are sold both directly and via the multi-cloud PSI App Store and can also be customized by customers and partners themselves. PSI was founded in 1969 and employs over 2,200 people worldwide.
