Large-disturbance voltage stability in power systems with high penetration of renewable energy



The transmission system operator (TSO), must ensure a stable power grid under large voltage disturbances, such as a solid three phased fault. However, defining the stability of a power grid is a complex task, as the power flow within the power grid has changed through the years. The reason of this, is due to a higher level of renewable energy sources with power electronics interfaced devices, and flow from HVDC connections.
Hereby a problem statement can be defined as following:
The purpose of this project is to investigate different large voltage disturbance criteria within the modern power grid.
