Web-based Geographical Visualization of Container Itineraries

Around 90% of the world cargo is transported in maritime containers, but only around 2% are physically inspected. This opens the possibility for illicit activities. A viable solution is to control containerized cargo through information-based risk analysis. Container route-based analysis has been considered a key factor in identifying potentially suspicious consignments. Essential part of itinerary analysis is the geographical visualization of the itinerary. In the present paper, we present initial work of a web-based system’s realization for interactive geographical visualization of container itinerary.JRC.G.4-Maritime affair

Electronic Logbook for Small Vessels - A Preliminary Study

All EU fishing vessels above 10m length are supposed to fill in fisheries logbooks. In the near future these logbooks will be replaced by electronic forms. Although this replacement is straight forward for large vessels (>15m) that can keep on board PCs and other electronic devices, it is more difficult for small vessels (<15m) that don't have the space and the power supply for this purpose. Other solutions based on handheld devices should be envisaged. However non of the current logbook software producers can offer a system based on handheld devices. Moreover the requested by the law reporting frequency should take into account the lack of satellite terminals on board of small fishing vessels. The report proposes various scenarios to optimise the use of handheld deviacies on board of small fishing vessels.JRC.G.3-Agricultur

Energy Management and Optimal Power Scheduling in a Smart Building under Uncertainty

In this Chapter, we consider a microgrid with a certain number of distributed energy resources (DER) components connected to an office building (in a university campus) provided with electricity by a utility company. We develop the initial version of the energy management system which is responsible for the optimal energy scheduling of the microgrid’s distributed energy resources. These resources include a photovoltaic (PV) installation, a Storage Energy System (ESS), a small Combined Heat and Power (CHP) unit, and a fleet of electric vehicles (EVs) used for work-related trips. The mobility behavior of the EVs fleet is modeled considering deterministic realizations of the probabilistic distributions used for the arrival/departure, and the time EVs remain parked. To investigate the impact of renewable generation and load unpredictability on the energy management system (EMS) operation, PV production and electric load are modeled under uncertainty using actual smart meters data for the scenarios formulation. We also assume that each DER component, through an EMS, can communicate and control the power exchange from and towards this component and that, two way communication with the utility company can be reached through aggregators using advanced metering equipment. We also consider a simplified thermal model that provides a specific level of thermal comfort to the building’s occupants, by meeting the predicted heating load. The energy produced by the DERs can be sold back to the grid by the microgrid manager and/or it can be stored for future utilization

An experimental approach for assessing the harmonic impact of fast charging electric vehicles on the distribution systems

Fast charging is seen by users as a preferential way for electric vehicles (EV) to extend average daily mobility. Fast chargers rated power, their expected operation mostly during peak hours and clustering in designated stations, raise significant concerns. On one hand it raises concerns about power quality standard requirements, especially harmonic distortion due to the use of power electronics connecting to high loads typically ranging from 18-24 kWh, and on the other hand infrastructure dimensioning and design for those investing on such facilities. We performed four sets of measurements during an EV complete fast charging cycles and analysed individual harmonic’s amplitude and phase angles behaviour and calculated the voltage and current total harmonic distortion (THD) and Total Demand Distortion (TDD) comparing it with IEEE519, IEC 61000/EN50160 standards. Additionally, we simulated, two vehicles being fast charged while connected to the same feeder, and analysed how the harmonic phase angles would relate. We concluded that the use of TDD was a better indicator than THD since the first one uses the maximum current (IL) and the latter uses the fundamental current, sometimes misleading conclusions, hence suggested to be included in IEC/EN standard updates. Voltage THD and TDD for the analysed charger, were within the standards limitations 1.2% and 12% respectively, however individual harmonics (11th and 13th ) failed to comply with the 5.5% limit in IEEE 519 (5% and 3% respectively in IEC61000). Phase angles tended to have preferential range differences from the fundamental. We found that the average difference between the same harmonic order phase angles, are lower than 90°, meaning that when more than one vehicle is connected to the same feeder the amplitudes will tend to add. Since the limits are dependable on the upstream short circuit current (ISC), if the number of vehicles increase (i.e. IL), the standard limits will decrease and eventually are broken. The harmonic limitation is hence a first binding condition, well before the power limitation is. The number of chargers will be limited first not by the power capacity of the upstream power circuit but by the harmonic limits for electric pollution.JRC.F.3-Energy Security, Systems and Marke

Smart Grid Interoperability Laboratory

The Smart Grid Interoperability Laboratory in Petten was inaugurated on 29/11/2018. The Smart Grid Interoperability Laboratory is designed to foster a common European approach to interoperable digital energy, focussing on the smart home, community and city levels. The facility in Petten is part of a larger activity of the Joint Research Centre, as the science and knowledge service of the European Commission, encompassing electric vehicles, smart grids and batteries. The activities in 2019 are highlighted in this report.JRC.C.3-Energy Security, Distribution and Market

Smart grid interoperability testing methodology

Smart grid interoperability is an important enabling aspect of electricity technology deployments. It involves all parts of the smart grid from generation to transmission and from distribution to consumption. Testing interoperability requires producing detailed test cases describing how smart grid components are intended to interact with each other. A systematic approach for developing smart grid interoperability tests may facilitate the dissemination of innovative solutions, the stability and resilience of the smart grid. This report provides an analysis of the methods applicable to smart grid interoperability tests. It comprises the body of methods and principles associated with smart grid interoperability and it proposes a methodology offering theoretical underpinning to the necessary set of methods and best practices for developing successfully smart grid interoperability testing specifications.JRC.C.3-Energy Security, Distribution and Market

ARTEFACTS: How do we want to deal with the future of our one and only planet?

The European Commission’s Science and Knowledge Service, the Joint Research Centre (JRC), decided to try working hand-in-hand with leading European science centres and museums. Behind this decision was the idea that the JRC could better support EU Institutions in engaging with the European public. The fact that European Union policies are firmly based on scientific evidence is a strong message which the JRC is uniquely able to illustrate. Such a collaboration would not only provide a platform to explain the benefits of EU policies to our daily lives but also provide an opportunity for European citizens to engage by taking a more active part in the EU policy making process for the future. A PILOT PROGRAMME To test the idea, the JRC launched an experimental programme to work with science museums: a perfect partner for three compelling reasons. Firstly, they attract a large and growing number of visitors. Leading science museums in Europe have typically 500 000 visitors per year. Furthermore, they are based in large European cities and attract local visitors as well as tourists from across Europe and beyond. The second reason for working with museums is that they have mastered the art of how to communicate key elements of sophisticated arguments across to the public and making complex topics of public interest readily accessible. That is a high-value added skill and a crucial part of the valorisation of public-funded research, never to be underestimated. Finally museums are, at present, undergoing something of a renaissance. Museums today are vibrant environments offering new techniques and technologies to both inform and entertain, and attract visitors of all demographics.JRC.H.2-Knowledge Management Methodologies, Communities and Disseminatio

XML Fuzzy Ranking

This paper proposes a method of ranking XML documents with respect to an Information Retrieval query by means of fuzzy logic. The proposed method allows imprecise queries to be evaluated against an XML document collection and it provides a model of ranking XML documents. In addition the proposed method enables sophisticated ranking of documents by employing proximity measures and the concept of editing (Levenshtein) distance between terms or XML paths.JRC.G.2-Support to external securit
