1. Enhanced Active Resonant DC Circuit Breakers for HVDC Grids
Abstract : High-voltage DC (HVDC) grids are considered promising for the electricity grid expansion required to integrate renewable energy sources into the existing infrastructure. DC fault currents increase rapidly and lack a current zero crossing. READ MORE

2. Steady state analysis of HVDC grid with Wind Power Plants
Abstract : The idea of building a multi-terminal, even a meshed HVDC grid in the North Sea, that can inter-connect surrounding nations, is being discussed widely. Such a system is expected to be realised in steps through the interconnection of wind power plants and electricity markets. READ MORE

3. On the Analysis of DC Network Dynamics of VSC-based HVDC Systems
Abstract : In this thesis, the dc network dynamics of VSC-HVDC systems is investigated through eigenvalue and frequency domain analysis. The eigenvalue analysis has been used to identify the factors that have an impact on the system stability. READ MORE

4. Expansion Governance of the Integrated North Seas Offshore Grid
Abstract : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. READ MORE

5. Main Circuits, Submodules, and Auxiliary Power Concepts for Converters in HVDC Grids
Abstract : In order to enable the massive introduction of renewable energies the need for high-voltage direct current (HVDC) grids is anticipated. Large, globally interconnected HVDC networks will likely be the most cost-efficient means to balance electricity demand and available generation. READ MORE
