1. Protection Strategies to Mitigate Major Power Systems Breakdowns
Sammanfattning : This thesis deals with new methods to improve the performance of power system protection in the case of voltage- and transient instability. These methods are designed primarily to mitigate power system breakdown. Relay algorithms are proposed where conventional distance protection is combined with additional relay criteria. LÄS MER
2. The Impact of Non-synchronous Generation on Power Systems Dynamics
Sammanfattning : Due to the increasing integration of Renewable Energy Sources (RES), and the installation of High Voltage Direct Current (HVDC) systems, more power is injected to the AC grid based on power electronic converters. This kind of power injection is called non-synchronous generation in this thesis. LÄS MER
