‘Future-ready’ grid control centre system

23 March 2021

Ellevio, Sweden’s second largest grid company, has contracted with Siemens Smart Infrastructure for the delivery of a new grid control system for its distribution network. The system, based on the proprietary Spectrum Power 7, is intended to improve handling of increased network complexities, abnormalities, and security threats, while improving ease of use by operators. Ellevio's control center in Karlstad is responsible for providing the energy supply for nearly a million citizens in the area. The grid control is to be set up in a flexible multi-site operation with a main control centre in Karlstad and a supporting control centre in Stockholm as back-up.

The system is expected to better monitor and control Ellevio's high, medium and low voltage power grid. The new system should also improve the decision-making process through 2D/3D situational awareness and visualisation. Integration to current and future Enterprise IT systems is ensured through proven service-oriented architecture (SOA) and web service capabilities and Common Information Model CIM (IEC 61968) compatibility. The new control system is expected to be operational in 2022.

"With the fast-changing energy landscape, we have seen the need to upgrade our control centre to meet increasing grid complexities … we need a secure platform to stay ahead of cybersecurity threats, and we need more transparency with the advent of more and more renewables, storage, and electromobility", commented Niklas Eklund of Ellevio.
