10. Protection of HVDC Grids Against Blackouts (Simulation)
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE
