The adoption of electric vehicles (EV) has to be complemented with the right charging infrastructure roll-out. This infrastructure is already in place in many cities throughout the main markets of China, EU and USA. Public policies are both taken at regional and/or at a city level targeting both EV adoption, but also charging infrastructure management. A growing trend is the increasing idle time over the years (time an EV is connected without charging), which directly impacts on the sizing of the infrastructure, hence its cost or availability.

The availability and continuity of energy supply play a key role in qualifying the energy security of a country. This report explores the meaning of energy security, according to the perceptions and preferences of a broad range of market actors. Making use of interviews and survey data taken in Estonia, the Netherlands and Portugal, the importance of an encompassing set of policy topics/measures is explored and described to investigate the relevance of different dimensions of energy security.

The Value of Lost Load (VoLL) is an indicator of the economic value that consumers place on the energy not served in case of a supply disruption, e.g. an electricity outage (blackout). VoLL is broadly used by industry and regulators for benchmarking the operating conditions of an energy system. The perceived worth of the reliability of the energy system can be used for assessing the economic convenience of future improvements, e.g. infrastructure investments, or to assess the damages caused by disruptions.

This report presents the results of a study on the Value of Lost Load (VoLL) in Greece for various scenarios of interruptions of power supply. The VoLL is the value of unserved energy, and quantifies the value of damages perceived by energy users, in case of a blackout. The VoLL is used as a proxy of the economic value of reliability or alternatively of the social costs of power outages.

As photovoltaic (PV) penetration increases in low-voltage distribution networks, voltage variation may become a problem. This is particularly important in residential single-phase systems, due to voltage unbalances created by the inflow of points in the network. The existing...

Exposing electric vehicles (EV) to extreme temperatures limits its performance and charging. For the foreseen adoption of EVs, it is not only important to study the technology behind it, but also the environment it will be inserted into. In Europe, temperatures ranging from...

Electric vehicle (EV) charging infrastructure rollout iswell underway in several power systems, namelyNorthAmerica, Japan, Europe, and China. In order to support EVcharging infrastructures design and operation, little attempt has been made to develop indicator-based methods characterising such networks across different regions...

Multi-type fast charging stations are being deployed over Europe as electric vehicle adoption becomes more popular. The growth of an electrical charging infrastructure in different countries poses different challenges related to its installation. One of these challenges is related to weather conditions that are extremely heterogeneous due to different latitudes, in which fast charging stations are located and whose impact on the charging performance is often neglected or unknown. ...

Smart Grid pilot projects and their assessment through a cost-benefit analysis are crucial to ensure that Smart
Grid and Smart Metering roll-out are economically reasonable and cost-effective. Analysing the Isernia pilot
project, the key result of the investigation is that an extra remuneration for such ambitious projects has been
crucial in turning the Distribution System Operator’s Return on Investment (RoI) positive.

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.

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.

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.

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.

The 2017 Outlook offers a snapshot of the state of play and of the latest developments in the field of smart grids in Europe. The analysis is based on a database of 950 R & D and demonstration projects, totalling around EUR 5 billion of investment. It aims to foster knowledge sharing and to inform future policymaking.

The document presents an update of the assessment framework, a methodology to assess smart grid projects of common interest, in line with Regulation (EU) No 347/2013 on guidelines for trans-European energy infrastructure. In this context, every 2 years the European Commission establishes an EU-wide list of projects of common interest (PCIs), consisting of key energy infrastructure projects in the EU. These are essential for completing the European internal energy market and reaching the EU’s energy policy objectives of affordable, secure and sustainable energy.

This paper seeks to investigate if the theoretical and political trends towards a more collective dimension of energy use are reflected in the design and development of demand side management (DSM) pilot projects in Europe. Specifically, the paper analyses DSM projects in the database of the Joint Research Centre (JRC) of the European Commission to capture signs of a new attention towards the wider context in which consumers live and towards the social dimension associated with energy consumption.
