“…In comparison, the first 1100 kV CSC HVDC line (currently under construction in China) will be able to transmit up to 12 GW, half the average power use of Spain (The Economist, 2017). Although immediate technical implementation of supergrid is not yet possible, most of the problems are not fundamental and can be solved given sufficient time (Van Hertem et al, 2010).…”

“…An alternative vision to smart grid is the supergrid, which focuses on connecting remote RES to the grid and bridging power systems over a large geographic region through long-distance HVDC cables that overlay the existing grid (Van Hertem, Ghandhari, & Delimar, 2010). The supergrid aims at reducing the variability of RES by aggregating a diverse portfolio and making remote RES available to more electricity users, by expanding and merging existing transmission capacity (Blarke & Jenkins, 2013).…”

In recent years, the debate on electricity market design in the EU has focused on the fitness-for-purpose of the existing dominant design, the appropriateness of energy policy that underpins the existing market design, and on the process through which energy policy is coordinated with market design. In this paper, we contribute to this debate on all three levels. First, we propose a 'module-and-level'-based framework to illustrate our diagnosis of coordination issues present in the EU's power markets. We apply this framework to make a systematic identification of existing misalignments between the components of current market design and physical RES integration/financial RES support schemes. Secondly, we argue that the role of energy policy is not just in managing existing trade-offs between competitiveness, sustainability, and reliability, but also in encouraging innovations that increase the compatibility of energy policy objectives in the future. Finally, we propose a seven-step condition-dependent evolution of power market design, where the government/regulatory authority plays the role of meta-coordinator, matching the adaptation of market-based coordination modules with a hybrid future where distributed energy resources coexist with centralised generation, while decentralised market participants trade with each other and with incumbents.

“…It has been long acknowledged that this offshore grid could be considered as a precursor to a European SuperGrid. It has also been proposed that this SuperGrid could connect the offshore wind generation, from the North Sea, to the potential solar generation in southern Europe, the geothermal generation in Iceland, and the hydro generation in Norway [2]. It has been well established that an offshore grid will be implemented using HVDC transmission, as it is more efficient and costeffective than HVAC when using submarine cables.…”

With increasing offshore wind generation, there is a strong argument for implementing a multi-terminal DC grid offshore by the interconnection of individual HVDC links. The point of intersection of three or more lines can be used to interconnect projects with different voltage levels and to control power distribution. It is being proposed that these points, or nodes, be implemented using DC devices. A highvoltage, high-power DC/DC converter will therefore be an important component of a DC node. This paper reviews possible DC/DC converter topologies, looking at device requirement, different voltage conversion ratio and fault management. The suitability of the converters considered, for use in a node in a HVDC offshore grid, is discussed. A resonant DC/DC converter topology is considered in detail and is modelled at a conversion ratio of two, and demonstrates high power efficiency.

“…With a large number of VSC converter stations far offshore from each country, it has been suggested that connecting the countries to each other using an HVDC grid would be beneficial for all [4]. The wind farms proposed are rated in the gigawatts and, with the addition of country to country transfers, the grid is likely to be transferring power in the tens of gigawatts.…”

Abstract-The large number of proposals for wind farm developments across northern Europe and the North Sea have lead to the suggestion that a European Supergrid using High Voltage DC (HVDC) would be beneficial. Grid formats of HVDC will use Voltage Source Converters (VSCs) with a fixed voltage polarity and power flow controlled through current magnitude and direction. The multi-level form of VSC looks set to displace 2-level for reasons of lower switching power loss and lower harmonics. Given the significant size of the power transfers involved compared to total capacity in GB and other smaller systems, there is a potential loss-of-infeed problem if a converter station or line fails. This paper examines the extent to which Multi-level Modular Converters (MMC) can continue to transfer some power following the loss of a subsystem such that a lossof-infeed is limited to some fraction of the total capacity. The subsystem faults tested were a single DC line to ground fault and a transformer phase fault. In both cases the converter is able to transfer 50% of rated power continuously with the fault applied. This result means that the HVDC converter stations and routes could possibly be built at higher ratings than the system loss-of-infeed limit.
