11. Application of PSS to Improve the Stability of a Power System With a High Penetration of Renewable Energy
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Unlike traditional power generation composed of synchronous generators, renewable energy in theform of solar and wind power does not add inertia to power systems. Therefore, as increasedproportions of renewable energy are added, the dynamics of the power system will be affected. READ MORE
