Protection requirements for integration of distributed energy sources

- Dr. Jorun I. Marvik, SINTEF Energy Research

This sub-project will review and recommend protection requirements for grids with DER. This work will be based on requirements developed within the former KMB-project ‘Distribution 2020’ [42], CIGRE working group JWG B5/C6.26, and experience from the utility and power plant owner sides. Of particular interest is the coordination of voltage and frequency protection with the feeder protection and the introduction of distance relays in distribution grids. Rating and technology of the DER-units are important factors. Power electronics interfaced units will be considered in addition to conventional generators.
