Economy of the Mediterranean energy: Chapter 7
The 2023 ENEMED Report, produced by SRM and the ESL@energycenter/Department of Energy/Politecnico of Turin, is now in its fifth edition and is dedicated to the interactions between geopolitics and energy with reference to emerging energy technologies.
The focus is once again on the current situation of the Mediterranean energy system, identifying and discussing possible evolutionary paths and highlighting the geopolitical implications that these could have. The aim is to highlight some of the key issues that need to be carefully considered in the short, medium and long term for an effective energy dialogue between the shores of the Mediterranean.
The volume contains an analysis of the Mediterranean energy context and prospects, with an overview of the most relevant technologies, the role of related critical raw materials and the role of electricity interconnectors in the Mediterranean context, deepening the shift from fossil-based to 'green' energy dialogue between the shores of the basin. A constant presence in this report is the synergy with the maritime sector, with this year's focus on new sustainable port models
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Impact of RES electricity exchanges between North Africa and the EU power systems and markets
Market and regulatory factors influencing smart-grid investment in Europe: Evidence from pilot projects and implications for reform
Electricity distribution system operators (DSOs) are expected to invest heavily in system innovation in the form of smart grids (SG) in order to help achieve energy policy goals. In this context, regulatory reforms to spur DSOs investments are considered a policy priority. Based on a review of the European regulatory status and using a dataset of 459 innovative SG projects, this study focuses on market and regulatory factors and performs a series of statistical tests to investigate how the different factor levels affecting SG investments in Europe. The results show that (1) lower market concentration in the electricity distribution sector (2) the use of incentive-based regulatory schemes; and (3) the adoption of innovation-stimulus mechanisms are key enablers of SG investment
Assessment framework for EV and PV synergies in emerging distribution systems
The next-generation electricity grid (“smart grid”) is expected to integrate interoperable technologies – particularly in the energy, transport, information and communication fields – with the aim to increase reliability, affordability and sustainability considering at the same time, distribution systems and market operation. In order to gauge the implications of the anticipated paradigm shift for the electricity system, new reference architectures and assessment methodologies shall be developed to properly capture the interactions between the different actors (especially utilities, operators, energy aggregators, end-users, etc.) and technologies to value and allocate the costs and benefits of such transformation. Against this background, this paper proposes a conceptual architecture and an assessment framework to explore how high penetration scenarios of electric vehicles and intermittent renewable generation can complement each other in emerging distribution networks. We start from the identification of the smart grid functionalities to be implemented in a system with distributed power injections under the need to supervise and coordinate myriads of decentralized and interoperable energy sources and actors. Relying upon the proposed smart grid conceptual architecture, we develop an assessment framework to maximize the renewable electricity and electric vehicle penetration for given electricity and transport systems. The application of the proposed assessment framework to a realistic case study, representing the distribution and mobility systems of a typical mid-size Italian city, illustrates how some of the limitations and constraints of the current electricity network operation and design approaches can be addressed and overcome. We show how integration of substantial amounts of energy production and electric-based transport technologies can be achieved while improving the reliability and sustainability performances of the emerging power systems
