Smart Transmission Grids Operation and Control A project funded by Objectives: And co-funded by Nordic TSOs and DSOs Address the challenges that the secure and reliable operation of the power grids will face in the future. Support the development of better tools for planning, operation and control of power grids We seek to establish an interdisciplinary theoretical and experimental foundation for research and development

Project partners Industry Academia Institute of Physical Energetics

Goals Create innovative applications that will enable operation and control of the Nordic power grid more reliably and with better information about security margins. Develop a research platform comprised by a power systems emulator (software and hardware labs), PMUs, PDCs and specialized software. Develop a set of software interfaces allowing PMUdata application development, and implementation.

Project Approach and Major Deliverables: A common real-time data infrastructure PMUs, PDCs and other HW installed at LV network to exchange real-time data RT data exchange over public internet A Nordic PMU Data Applications Software Platform A common SW platform for prototyping of new applications New application prototypes Testing at TSOs Set-up hardware laboratories for application development and testing of PMU applications Labs at NTNU, KTH and DTU.

EU-prosjekt: Kommentarer og erfaringer EU-prosjekt er mer målrettede Tvinges til reelt samarbeid (deliverables og tidsfrister) Utfordringer ved NTNU mht å rekruttere forskere og prosjektledere til å jobbe på EU-prosjekt.. Vi har god hjelp fra EU-kontoret på IME
