Optimal Solutions for Protection, Control and Automation in the Power System

The project covered all grid levels, 1 – 420 kV.

The project had two subprojects:

• Opportunities and potentials of new technology (PCA and ICT) and functionality
• Methods, models and decision support for finding optimal PCA solutions
