Effect of the European Union Emission Trading System on promoting industrial electrification
No full textpeer reviewedThe European Union designed the Emission Trading System (EU-ETS) aiming to achieve climate neutrality by 2050. Theoretically, this mechanism should incentivize consumers to emit less CO2 and invest in green technologies. While there is evidence that it helped reduce CO2 emissions, it is unclear whether it helped promote green investments. This paper answers such a question based on a large European industry. We demonstrate that historical EU-ETS prices have not been incentive enough for this industry to transition from gas to electricity to produce steam. Our calculations show that companies would have to pay at least 30,57% more for operational costs when using only electricity for heat generation compared to natural gas, even with the addition of EU-ETS prices. We argue that using both conventional and green technologies might be the way to proceed since such a hybrid solution can reduce energy costs by up to 1,68% and CO2 emissions by 16,23%. These savings could pay back the electric boiler's investment until the gas boiler's lifetime is terminated. Nevertheless, even with the addition of the EU-ETS cost, the operational cost of the electric boiler in 2030 is expected to be higher than gas unless electricity spot prices are controlled
Distributionally Fair Peer-to-Peer Electricity Trading
Get PDFPeer-to-peer energy trading platforms enable direct electricity exchanges between
peers who belong to the same energy community. In a semi-decentralized
system, a community manager adheres to grid restrictions while optimizing
social welfare. However, with no further supervision, some peers can be discriminated
against from participating in the electricity trades. To solve this
issue, this paper proposes an optimization-based mechanism to enable distributionally
fair peer-to-peer electricity trading. For the implementation of our
mechanism, peers are grouped by energy poverty level. The proposed model
aims to redistribute the electricity trades to minimize the maximum Wasserstein
distance among the transaction distributions linked to the groups while
limiting the sacrifice level with a predefined parameter. We demonstrate the
effectiveness of our proposal using the IEEE 33-bus distribution grid, simulating
an energy community with 1600 peers. Results indicate that up to 70.1%
of unfairness can be eliminated by using our proposed model, even achieving
a full elimination when including a non-profit community photovoltaic plant
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Exploring the Effectiveness of the Integrated European Balancing Markets in Encouraging Demand Response Engagement
No full textpeer reviewedThe energy transition is reducing the available flexibility of the power system. Consequently, there is a pressing need to identify new flexibility sources and adapt market designs to ensure a reliable and stable operation of the power system. Among the potential solutions, Demand Response (DR) has shown great potential to offer flexibility through ancillary markets. This paper presents a comprehensive analysis of the market design of the Integrated European Balancing Markets, focusing on the FCR, MARI and PICASSO platforms. We evaluate their effectiveness in fostering DR engagement, identifying both strengths and weaknesses. While characteristics such as capacity and granularity hinder DR participation across all platforms, linking and grouping in MARI can increase DR involvement. We propose enhancements, including the addition of linking and grouping characteristics to PICASSO and the approval of conditional linking to complex bids to further incentivize DR participation
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
