This article addresses the potential of interconnecting electricity systems to geographically aggregate remotely located variable power sources. Increasing the deployment of power generators using variable renewable power sources, such as wind and solar, brings power balancing challenges in electricity systems. One mean to achieve power balancing and to share balancing resources, is to interconnect.


European representative electricity distribution networks


C. Mateo, G. Prettico, T. Gómez, R. Cossent, F. Gangale, P. Frías, G. Fulli
Publication Category: Journal Papers Publication year: 2018 Activity Type: Software / Desktop Research Area: Smart Grids

In Europe there is a great diversity of distribution grids and distribution system operators (DSOs) and a consolidated and shared knowledge of their techno-economic features is missing. This fact represents a major hindrance for fully assessing the performances of distribution grids evolving towards Smart Grids (SG) embedding low-carbon technologies, digital services and emerging actors. In order to contribute to bridge this knowledge gap, this paper presents a methodology to build representative distribution networks.


Power Grid Recovery after Natural Hazard Impact


Georgios Marios Karagiannis, Stamatios Chondrogiannis, Elisabeth Krausmann, Zehra Irem Turksezer
Publication Category: Reports Publication year: 2017 Activity Type: Desktop Research Area: Integrated power systems

This study analyses the performance of the power grid during 16 earthquakes, 15 space weather events and 20 floods. It concludes that different natural hazards affect the power grid in different ways. Earthquakes cause inertial damage to heavy equipment and brittle items, and ground failure and soil liquefaction can be devastating to electric infrastructure assets. Recovery time is driven by the balance of repairs and capabilities. Poor access to damaged facilities, due to landslides or traffic congestion, can also delay repairs.


A China-EU electricity transmission link


M. Ardelean, P. Minnebo
Publication Category: Reports Publication year: 2017 Activity Type: Desktop Research Area: Super Grids

This report looks at the potential routes for a future power interconnection between EU and China. China has launched in 2016 the idea of transmitting electricity as far as Germany via an Ultra High Voltage Direct Current (UHVDC) link. China intends to exploit its Renewable Energy Sources (RES) from north-eastern regions both for domestic use and for export. The country has the capabilities to design and build long and powerful systems to transmit electricity across the country for thousands of kilometres.
