Realising the Isle of Wight’s aspirations for renewable energy power generation and local consumption
No full textTransitioning to net-zero carbon emissions will necessitate the use of many low-carbon technologies such as electric vehicles (EV), heat pumps (HP), micro- and utility-scale low-carbon electricity generation– such as solar photovoltaics. All such systems are likely to be rapidly deployed and connected to the electrical network at varying voltage levels. This is predicted to have a fundamental change to net-demand and substation load through transformers, which the current network infrastructure was not originally designed for. Hence, there is risk of faults occurring within the network, one of which is exceeding thermal limits due to high demand. This provides a threat to energy security and reliability as outages may occur due to such faults. To facilitate this transition, there is a need for high-resolution net-demand and constraint forecasting to assist Distribution Network Operators (DNO) with effective network planning.Within the context of the Isle of Wight (IoW), an island off the south-coast of the UK in the English Channel, this research proposes a methodology to determine the areas at greatest risk of constraints arising and when they may occur, and how these can be effectively managed to assist the IoW Council’s energy aspirations. The IoW Council wishes to transition to net-zero by 2040 and become self-sufficient in electricity from local renewable sources. By using actual half-hourly scaled EV charging and HP demand data, and weather data for the IoW in conjunction with technology penetration projections, potential constraint events were forecasted for different technologies rate of uptake. It was found that network constraints could arise as soon as 2030 with regular faults occurring soon after, which shows the urgency for immediate intervention.There are a range of interventions that can be considered by the DNO to manage and alleviate network constraints. The traditional method is to reinforce the network which increases the connectable capacity however, this is often time-consuming and expensive. This research proposes alternative interventions that the DNO should consider including utility- and micro-scale battery storage systems (BSS), time-of-use tariffs, private wire connections, an increase in the connected low-carbon generation capacity, and combinations of all these interventions. It was found that a combination of interventions is most beneficial to the DNO and can provide effective protection to the network against power constraints. This will also assist with the IoW Council’s aspirations as well as ensure energy security during the transition to net-zero. A business case for the DNO was created by completing economic analysis to protect the network from constraints arising across the IoW. This analysis compares the Capital Expenditure (Capex) of reinforcing the network to that of the utility-scale BSS capacity required to protect the network on its own, and as a combination of other interventions. An incentive scheme is also proposed in the research to incentivise the purchase of micro-scale BSS, which can absorb micro-scale low-carbon generation (e.g. rooftop solar photovoltaic systems) on site to be used during times when demand increases and provide protection to the network by reducing power flows through it. The incentivisation scheme proposed found that by subsidising the Capex of a micro-scale BSS by less than 40% provides the DNO with financial benefits as opposed to solely deploying utility-scale BSS to protect the network.The proposed methods applied are generalisable and can be replicated in other areas of the UK, globally, and should provide advice to other local authorities and DNO who are likely to experience similar challenges as they make their net-zero transition

No full textThe University of Southampton's (UoS) vision is that by 2030, sustainability will be a part of everything the University does; our individual behaviours, how we work together, and how we make decisions for the future. This is key to achieving our mission of changing the world for the better. The Sustainability Strategic Plan (SSP) is one of ten Strategic Plans created to underpin and drive forward the overall University Strategy. The SSP was developed to deliver on its sustainability targets and sets out six Goals to achieve these targets as highlighted in Figure 1. The six Goals do not only address reducing our emissions, but also cover embedding sustainability in our teaching, research and investment .This is the second annual report on the development of the University of Southampton's Sustainability Strategic Plan and progress against its 6 Goals for the years 2024-25. The report provides a summary of the planned work across the 6 Goals, whereby the first three relate to our institutional emissions reporting under the various scopes of the Greenhouse Gas Reporting Protocol. The latter 3 Goals of the Plan cover education, research, and investment

LATENT - findings from a two year heat deferral field trial
No full textIn order to meet UK 'net zero' objectives, residential heat demand is to be decarbonised through a combination of electrification (alongside the decarbonisation of electricity generation) and energy efficiency measures. This strategy, in combination with electric vehicles, could lead to a 200-300% increase in the UK's annual electricity demand and could introduce serious capacity issues for the electricity system. In the future, residential electrical heating or electric vehicle charging loads may need to be controlled remotely and adjusted to better suit the capacity of electricity network infrastructure. Here we present findings from a two year field trial which aims to understand issues surrounding third-party control of electric heating systems (including heat pumps), in which a number of aspects were investigated, including: user behaviour and attitudes and the thermal response of dwellings
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
