Interview with Thomas Böhmer, Executive Vice President at PSI Software
Hybrid AC/DC and HVDC power systems have the potential to increase energy efficiency, and support the widespread integration of renewable energies.
The transformation of current AC power systems to hybrid AC/DC and with HVDC brings several challenges, however. Common power systems, and also the SCADA system, were originally designed for AC grids. Therefore, maintaining the stability of the power system is the most pressing technical and operational challenge.
Frequency, rotor, voltage, oscillation, and protection schemes must be updated properly to ensure the future reliability of the hybrid AC/DC power systems.
PSI is closely involved in the DAEDALOS project, a 48-month scheme divided in 7 Work Packages (WP) that aims to develop a comprehensive framework and advanced software tools to support the planning, operation and monitoring of AC/DC hybrid systems and MVDC/HVDC grids on a state-of-the-art SCADA system.
The DAEDALOS project will contribute to the acceleration of the energy transition and the integration of intermittent renewable energy sources (RES).
The project comprises the partners from European grid operators, industry - such as PSI - and leading research institutes. This collaboration is well placed to achieve the evolution towards hybrid AC/DC power systems. It will also work on developing the software tools to cover the aspects of grid planning, operation, and monitoring for the hybrid AC/DC…
