Drivers for the development of HVDC grids

Dirk Van Hertem

Open publisher page 17 citations

Abstract

This chapter describes the evolution and the drivers in energy policy, resulting in a strong move towards the development of the offshore grid and super grid. As the perceived drive is strongest in Europe, the main focus is on the evolutions there. The specific drivers for high-voltage DC (HVDC) grids are the liberalization of the energy sector and the increase of renewable generation in the energy mix. With respect to the applicability for grid investments, the power-flow-controlling devices are being categorized into two types: flexible AC transmission systems (FACTSs) including phase-shifting transformers (PST) and high-voltage DC (HVDC) solutions. HVDC transmission systems transmit electric power at zero frequency and use power electronic converters to interface between the AC grid and the DC grid. HVDC offers an inherent active power control, making it more flexible in use and easier to limit overloads in the system.
