Optimizing plug-in electric vehicle charging in interaction with a small office building
No full textThis paper considers the integration of plug-in electric vehicles (PEVs) in micro-grids. Extending a theoretical framework for mobile storage connection, the economic analysis here turns to the interactions of commuters and their driving behavior with office buildings. An illustrative example for a real office building is reported. The chosen system includes solar thermal, photovoltaic, combined heat and power generation as well as an array of plug-in electric vehicles with a combined aggregated capaci-ty of 864 kWh. With the benefit-sharing mechanism proposed here and idea-lized circumstances, estimated cost savings of 5% are possible. Different pricing schemes were applied which include flat rates, demand charges, as well as hourly variable final customer tariffs and their effects on the operation of intermittent storage were revealed and examined in detail. Because the plug-in electric vehicle connection coincides with peak heat and electricity loads as well as solar radiation, it is possible to shift energy demand as desired in order to realize cost savings. --Battery storage,building management systems,dispersed storage and generation,electric vehicles,load management,microgrid,optimization methods,power system economics,road vehicle electric propulsion

Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems: Through Market Prices and Use-of-System Network Charges
No full textBoth electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world. To this end, electrifying personal vehicles is believed to contribute to an affordable and reliable energy model that provides tolerable environmental impact. Representing an inherently flexible electricity demand, plug-in electric vehicles (PEVs) promise to facilitate the integration of variable renewable energy sources. Yet, how should the PEVs' system usage be ideally coordinated for providing benefits to electric power systems in the presence of resource scarcity? The thesis develops a model of an aggregation agent as the interface to the wholesale electricity generators, which is envisaged to be in charge of procuring energy in electricity markets, exposed to uncertainty in prices, fleet availability and demand requirements. This aggregator could coordinate the PEV charging either with direct load control (DLC), i.e., sending power set points to the individual vehicles, or with indirect load control (ILC), i.e., by sending retail price signals. Contributing to the technical literature this thesis has on the one hand proposed a two-stage stochastic linear program for the PEV aggregator's day-ahead and balancing decisions with DLC over a large fleet of PEVs, while accounting for conditional value at risk in the objective function. On the other hand, it has put forward a formulation of ILC coordination as a bi-level optimization problem given by mathematical programming with equilibrium constraints, in which 1) the upper level decisions on retail tariffs and optimal bidding in electricity markets are subject to 2) the lower level client-side optimization of PEV charging schedules. These decisions may respect a potential discomfort that could arise when PEV users have to deviate from their preferred charging schedule. Set in an existing, real medium voltage distribution network with urban characteristics and spatial PEV mobility, network UoS tariffs for capacity have been applied to both DLC and ILC scheduling by a PEV aggregator.Engineering, Systems and ServicesTechnology, Policy and Managemen
"The Translingual Sensibility: A Conversation Between Steven G. Kellman and Ilan Stavans"
No full textDialogue might be the most appropriate medium for reflections on translingualism. In a dialogue conducted by email over the course of ten days, Steven G. Kellman and Ilan Stavans consider the validity and implications of linguistic determinism. Their conversation examines whether some words that seem to embody the unique Weltanschaaung of a particular culture – such as Schadenfreude, duende, or mångata – can be appropriated, if not translated, into another culture. Pondering whether there are any inherent qualities that distinguish texts by monolingual writers such as Jane Austen and William Faulkner from work by authors who switch languages, such as Samuel Beckett and Vladimir Nabokov, they agree on the usefulness of thinking in terms of a translingual sensibility. Apart from the biographical circumstances of the author, a text possesses a translingual sensibility if it embodies an awareness of both the power and the limitations of its own verbal medium
[Book Review] "Understanding street culture: Poverty, crime, youth, and cool" by J. Ilan
No full textIn <i>Understanding Street Culture</i>, Jonathan Ilan analyzes one of the key areas of future concern for young people: how they engage in street culture and the links between street cultural practices and disparate forms of marginality, criminalization, poverty, transgression, and consumerism. Chapter 1 begins with an inquiry into street culture as concept and mode of theorization. The author contends that it is not “a form of ‘resistance’, but rather a posture of defiance” (21). The precise differences between these terms is not very clear, given that the definitions themselves tend to imply one another (resistance meaning refusal to comply and defiance meaning open resistance and disobedience). In the conclusion, however, Ilan does hint at how thinking about street culture as defiance is a more suitable conceptualization than as resistance, which ought to be “reserved for phenomena more overtly political in nature,” suggesting that “street culture generally channels the defiance of exclusion as opposed to practical action towards altering configurations of power” (174). Ilan’s analysis does not, however, elucidate precisely how defiance may be less political. Importantly, street culture is reconceptualized “as a spectrum running from stronger to weaker variants that ultimately provides a similar scheme for understanding the world” (23)
What Do You See in Your Bot? Lessons from KAS Bank
No full textThe introduction of robotic process automation (RPA) has created an opportunity for humans to interact with bots. While the promise of RPA has been widely discussed, there are reports suggesting that firms struggle to benefit from RPA. Clearly, interactions between bots and humans do not always yield expected efficiencies and service improvements. However, it is not completely clear what such human-bot interactions entail and how these interactions are perceived by humans. Based on a case study at the Dutch KAS Bank, this paper presents three challenges faced by humans, and consequently the perspectives humans develop about bots and their abilities to perform work. We then provide a set of five practices that are associated with the management of the interactions between humans and bots.Information and Communication Technolog

Plug-in Electric Vehicle Interactions with a Small Office Building: An Economic Analysis using DER-CAM
No full textIt is generally believed that plug-in electric vehicles (PEVs) offer environmental and energy security advantages compared to conventional vehicles. Policies are stimulating electric transportation deployment, and PEV adoption may grow significantly. New technology and business models are being developed to organize the PEV interface and their interaction with the wider grid. This paper analyzes the PEVs' integration into a building's Energy Management System (EMS), differentiating between vehicle to macrogrid (V2M) and vehicle to microgrid (V2m) applications. This relationship is modeled by the Distributed Energy Resources Customer Adoption Model (DER-CAM), which finds optimal equipment combinations to meet microgrid requirements at minimum cost, carbon footprint, or other criteria. Results derive battery value to the building and the possibility of a contractual affiliation sharing the benefit. Under simple annual fixed payments and energy exchange agreements, vehicles are primarily used to avoid peak demand charges supplying cheaper off-peak electricity to the building during workdays

A chamber of echo : on the post-comics of Ilan Manouach
No full textThis chapter presents the work and trajectory of conceptual comics artist Ilan Manouach. Focusing on points of convergence between theory, practice, and technology, it suggests that Manouach's work experiments with ways of 'withdrawing' or 'undrawing' the traditional author from the body of work in order to produce unsettling experiences that qualify as an expansion, extrapolation, or deviation from comics culture
