The challenge

The power grid of the future will be more unpredictable and will have different characteristics, due to an increased share of renewable energy, changed consumption patterns and a greater exchange of power across national borders. Operation of the transmission grid will become more demanding and Statnett, as the TSO, must use new real-time methods and tools to maintain security of supply.

The goal

The project aims to develop and test methods for real-time status estimation, monitoring and control in tomorrow’s Nordic transmission grids. Based on collected Phasor Measurement Unit (PMU) data for the Nordic transmission grid, voltage stability will be monitored and oscillations detected in prototypes of new monitoring systems. Real-time control applications may include voltage profile control to increase voltage stability, and automatic measures to mitigate oscillations. The use of hybrid or linear status estimation will be demonstrated to achieve better calculation results and shorter computational time.

The project

SPARC is divided into four sub-projects that aim to contribute to the development of new methods and better tools for improved monitoring, control and protection of the transmission grid.

  1. PMU-based methods for hybrid and linear status estimation
  2. PMU applications for coordinated real-time control
  3. PMU-based system protection
  4. Demonstration in a relevant lab environment, with test examples validating the methods and applications.
