PROJECT TITLE :

Guest Editorial Special Section on HVDC Systems for Large Offshore Wind Power Plants

ABSTRACT:

The papers during this special section specialize in HVDC systems for large offshore wind power plants. These plants have experienced an important growth within the last decade and are becoming a key energy source worldwide. Offshore wind presents clear blessings due to high and stable wind speeds offshore, enabling the use of larger wind turbines than those commonly used on inland wind power plants. However, transmitting power to load centres also brings a variety of technical challenges. Depending on the space to the shore and the power rating, AC or DC technology might be the preferable possibility for integrating offshore wind power to onshore grids. There are a range of problems which need to be thought of requiring substantial analysis and development. For DC connections, (Voltage Source Converter) VSC-HVDC technology has shown benefits over (Line Commutated Converter) LCC-HVDC. The event of multiterminal HVDC grids though brings additional challenges related to system operation, management, and protection and coordination between HVDC converters, wind power plants, and therefore the onshore system. The event of power electronic switches has reached a point where the dimensions, rating, and also the system potency can meet the requirements of economic HVDC. Wind power plants connected to HVDC transmission system need specific control and protection coordination between HVDC converters and wind turbines.
