This paper provides a comprehensive discussion of the market value of variable renewable energy (VRE). The inherent variability of wind speeds and solar radiation affects the price that VRE generators receive on the market (market value). During windy and sunny times the additional electricity supply reduces the prices. Because the drop is larger with more installed capacity, the market value of VRE falls with higher penetration rate. This study aims to develop a better understanding on how the market value with penetration, and how policies and prices affect the market value. Quantitative evidence is derived from a review of published studies, regression analysis of market data, and the calibrated model of the European electricity market EMMA. We find the value of wind power to fall from 110% of the average power price to 50-80% as wind penetration increases from zero to 30% of total electricity consumption. For solar power, similarly low value levels are reached already at 15% penetration. Hence, competitive large-scale renewable deployment will be more difficult to accomplish than as many anticipate. © 2013 Elsevier B.V. Source

As the patterns of power generation and distribution are rapidly changing in Europe towards a highly dispersed and volatile system, Distribution System Operators need to completely change traditional ways of grid operations. Currently developed solutions to increase the intelligence of medium and low voltage grids to cope with this task are often highly specialized, non-replicable and therefore not cost-effective. It is therefore the aim of this project to assess the optimal level of intelligence in the distribution network and to determine the replicable technological options that will allow a cost-effective and reliable enhancement of observability and controllability of the future distribution networks in Europe. DISCERN will build on five demonstration projects operated by major European DSOs. The involved demonstration sites unite a variety of technological approaches addressing different challenges. They hereby constitute the main resource of DISCERN. In addition, DISCERN will liaise with other EEGI smart grid innovation projects in Europe in a series of workshops and leverage on their results. Hence, DISCERN will become part of the EEGI family of projects. Based on comparative assessment, guided by a set of Key Performance Indicators, of technological options, solutions and operational processes, the project will define recommendations on replicable solutions. Moreover, DISCERN will demonstrate innovative solutions in field tests and simulations. As a result, DISCERN will enable DSOs to more rationally manage their networks and to plan their extension thereby facilitating the large scale introduction of renewable generation necessary for the transformation of the energy system. To achieve its objective, DISCERN builds on a strong European consortium which includes five DSOs, technology providers, research institutes and universities as well as a technical consultancy.

The overall aim of NewBusFuel is to resolve a significant knowledge gap around the technologies and engineering solutions required for the refuelling of a large number of buses at a single bus depot. Bus depot scale refuelling imposes significant new challenges which have not yet been tackled by the hydrogen refuelling sector: Scale throughputs in excess of 2,000kg/day (compared to 100kg/day for current passenger car stations) Ultra-high reliability to ensure close to 100% available supply for the public transport networks which will rely on hydrogen Short refuelling window buses need to be refuelled in a short overnight window, leading to rapid H2 throughput Footprint needs to be reduced to fit within busy urban bus depots Volume of hydrogen storage which can exceed 10 tonnes per depot and leads to new regulatory and safety constraints A large and pan-European consortium will develop solutions to these challenges. The consortium involves 10 of Europes leading hydrogen station providers. These partners will work with 12 bus operators in Europe, each of whom have demonstrated political support for the deployment of hydrogen bus fleets. In each location engineering studies will be produced, by collaborative design teams involving bus operators and industrial HRS experts, each defining the optimal design, hydrogen supply route, commercial arrangements and the practicalities for a hydrogen station capable of providing fuel to a fleet of fuel cell buses (75-260 buses). Public reports will be prepared based on an analysis across the studies, with an aim to provide design guidelines to bus operators considering deploying hydrogen buses, as well as to demonstrate the range of depot fuelling solutions which exist (and their economics) to a wider audience. These results will be disseminated widely to provide confidence to the whole bus sector that this potential barrier to commercialisation of hydrogen bus technology has been overcome.

The MTO-E method for event investigation is described in the light of almost 20 years of usage in the Swedish nuclear industry. Various problems are addressed in the context of the method, e.g. accident models, causality, the use of the barrier concept, the meaning of safety culture, and the process of going from problem identification to problem solving. It is argued that future applications of in-depth investigations should focus more on (innovative) methods when suggesting remedial actions as a consequence of information derived from event investigations. © 2009 Elsevier Ltd.

Unlike the control and observability put in service in HV/MV, LV networks are still being substantially managed as usual: no visibility of power and voltage or grid components status, poor knowledge of connectivity, manual operation of switches or few tools for worker support. The LV grid characteristics (radial topology, exposition to local disturbances, local accumulation of distributed generation, technical and no-technical loses, aging heterogeneous, etc.) limit the construction and refurbish of LV electric infrastructure and the integration on it of grid remote monitoring and operation and automation resources, bringing to difficulties in the implementation of the LV Smart Grid and the integration of Distributed Generation Resources and Active Demand Management (ADM). Smart metering deployment Mandates offer an opportunity to maximize the gains derived from the obliged functions to be deployed related to smart metering, developing and integrating additional innovative grid and ICT infrastructure, functions, services and tools improving grid operation performance and quality and paving the way for benefits and business opportunities for the involved actors (DSOs, customers, retailers and ESCOs). The project aims to develop, deploy and demonstrate innovative solutions (grid systems, functions, services and tools) for advanced Operation and Exploitation of LV/MV networks in a fully smart grid environment improving the capacity of that networks as enablers for Distributed Generation, ADM, Customer empowering and business opportunities. The project proposes 4 real pilots in Portugal, Poland, Spain and Sweden covering: Smart grid monitoring and operation, advanced grid maintenance, DER and ADM integration and active Consumer awareness and participation with cost efficiency. Also proposes specific WPs to maximize the socioeconomic impact of results, especially for their market uptake, business opportunities triggering and society awareness on the smart grid benefits.
