Les réseaux actuels et le courant continu: Nanogrilles et Microgrilles pour télécom, centres de données, les bâtiments commerciaux et militaires

 

Le marché pour les réseaux de distribution de courant continu n’est pas un marché unique, cohérent. Il englobe plusieurs possibilités allant des tours de télécommunication aux centres de données, bâtiments commerciaux qui gravitent autour de différentes hypothèses de marché. L’industrie se concentre actuellement sur la distribution moyenne tension concentrée sur le segment de marché des centres de données, mais qui pourrait également s’appliquer aux bâtiments commerciaux.

Un débat se poursuit sur les avantages et les inconvénients du courant continu. La majorité des technologies développées à base de courant continu touchent soit la haute tension (plus de 1000 V) ou la basse tension (moins de 100V) niveau. Un autre défi survient avec les nanogrilles et les microgrilles.

The market for direct current (DC) distribution networks encompasses several disparate opportunities — telecommunications towers, data centres, grid-tied commercial buildings, and off-grid military networks — that revolve around different market assumptions, dynamics, and drivers. The industry is currently focused on medium-voltage DC distribution networks — systems that are mostly concentrated on the data centre market segment, but which can also apply to commercial buildings.

A heated debate continues about the advantages and disadvantages of DC. The majority of progress in developing DC-based technologies has occurred at either the high-voltage (more than 1,000V) or low-voltage (less than 100V) level. Since microgrids and building-scale nanogrids typically operate at medium voltage (roughly 380V–400V), much work needs to be done to bridge this voltage innovation gap. Another challenge facing DC distribution networks lies with the need for standards and open grid architectures that can help integrate the increasing diversity of resources. Yet, there is momentum at the distribution level of electricity service to diversify power offerings and pursue hybrid solutions that incorporate a growing proportion of DC. According to Navigant Research, implementation revenue in the global DC distribution network market is expected to grow from $2.8 billion in 2015 to $5.1 billion in 2024 under a base scenario.

This Navigant Research report analyzes the global market for DC distribution networks in four key segments: off-grid/bad grid telecommunications, data centres, commercial building grids, and off-grid military applications. The study provides an analysis of the market issues, including opportunities, drivers, and implementation challenges, associated with DC distribution networks. Global market forecasts for capacity and implementation revenue, broken out by segment, region, and scenario, extend through 2024.
