Smart charging in the Netherlands

As the Dutch electric vehicle (EV) fleet continues to expand, so will the amount of charging sessions increase. This expanding demand for energy will add on to the already existing strain on the grid, primarily during peak hours on workdays in the early morning and evening. This growing energy demand requires new methods to handle the charging of EVs, to distribute the available energy in the most effective way. Therefore, a large number of ‘smart charging’ initiatives have recently been developed, whereby the charging session of the EV is based on the conditions of the energy grid. However, the term smart charging is used for a variety of smart charging initiatives, often involving different optimization strategies and charging processes. For most practitioners, as well as academics, it is hard to distinguish the large range of smart charging initiatives initiated in recent years, how they differentiate from each other and how they contribute to a smarter charging infrastructure. This paper has the objective to provide an overview of smart charging initiatives in the Netherlands and develop a categorization of smart charging initiatives regarding objectives, proposed measures and intended contributions. We will do so by looking at initiatives that focus on smart charging at a household level, investigating the smart charging possibilities for EV owners who either make use of a private or (semi-)public charging point. The different smart charging initiatives will be analyzed and explicated in combination with a literature study, focusing on the different optimization strategies and requirements to smart charge an electric vehicle.

New journalism 3.0 – aggregation, content farms and Huffinization

Journalists in the 21st century are expected to work for different platforms, gather online information, become multi‐media professionals, and learn how to deal with amateur contributions. The business model of gathering, producing and distributing news changed rapidly. Producing content is not enough; moderation and curation are at least as important when it comes to working for digital platforms. There is a growing pressure on news organizations to produce more inexpensive content for digital platforms, resulting in new models of low‐cost or even free content production. Aggregation, either by humans or machines ‘finding’ news and re‐publishing it, is gaining importance. At so‐called ‘content farms’ freelancers, part‐timers and amateurs produce articles that are expected to end up high in web searches. Apart from this low‐pay model a no‐pay model emerged were bloggers write for no compensation at all. At the Huffington Post thousands of bloggers actually work for free. Other websites use similar models, sometimes offering writers a fixed price depending on the number of clicks a page gets. We analyse the background, the consequences for journalists and journalism and the implications for online news organizations. We investigate aggregation services and content farms and no‐pay or low‐pay news websites that mainly use bloggers for input.

Aggregation level determines reliability of accelerometer Fitbit Ultra

The aim of this study is to examine the inter-device reliability of an activity tracker on three different levels of aggregation: minute, hour and day.

Deliverable D 1.1: Whitebook requirements

The following report aims to introduce the main me2 specifications, and to describe the requirements needed to develop the me2 project. Me2 is a technological platform where the behaviours related to energy consumption could be monitored, and also to increase the energy efficiency.In order to have a better understanding about the use of that kind of platforms, a brief literature review is firstly presented, where some of the main behaviour changing mechanisms practices are highlighted. Also, a policy analysis was developed to give an extended overview of the existing market structures and barriers, as well as, the technical features that are relevant for the development of a venture like me2.The report will end with a detailed description of what the me2 user will be like. This information is mostly based on the pre-pilot survey and on a cross-cultural analysis between Portugal and the Netherlands. This comparison is fundamental for a better understanding about the target community used in this project. Concerning to the functional systems requirements, they are also described in this report, giving special attention to what is called me2 Logic, that includes the front-end platform, back-end activities, and the algorithms to user engagement.Therefore, this report delivers, in a very detailed way, all the reviewed information and procedures needed to be determined prior to the platform’s establishment, and regarding its implementation for the project’s first pilot in Lisbon.

Deriving vehicle-to-grid business models from consumer preferences

Combining electric cars with utility services seems to be a natural fit and holds the promise to tackle various mobility as well as electricity challenges at the same time. So far no viable business model for vehicle-to-grid technology has emerged, raising the question which characteristics a vehicle-to-grid business model should have. Drawing on an exploratory study amongst 189 Dutch consumers this study seeks to understand consumer preferences in vehicle-to-grid business models using conjoint analysis, factor analysis and cluster analysis. The results suggest that consumers prefer private ownership of an EV and a bidirectional charger instead of community ownership of bidirectional charger, they prefer utility companies instead of car companies as the aggregator and they require home and public charging. The most salient attributes in a V2G business model seem to be functional rather than financial or social. The customer segment with the highest willingness to adopt V2G prefers functional attributes. Based on the findings, the study proposes a business model that incorporates the derived preferences
