Abstract

The electrical power grid is a fundamental infrastructure in today’s society. The synchronization of the frequency to nominal frequency over all the network is essential for the proper functioning of the power grid. The current transition to a more distributed generation by weather dependent renewable power sources, which are inherently more prone to fluctuations, poses great challenges to the functioning of the power grid. Among these fluctuations, the frequency fluctuations negatively affect the power supply and stability of the power grid. In this thesis, we focus on load frequency control laws that can effectively suppress the frequency fluctuations, and methods that can improve the synchronization stability...
