Multidisciplinary Smart Grid Research and the Design of Users Georgia Gaye & Grégoire Wallenborn Centre for Studies on Sustainable Development Université Libre de Bruxelles Brussels, Belgium Abstract— Working in a multidisciplinary smart grid research interests. We represent the part of the project that mixes as social scientists, we show how engineering and economic anthropology, design and sociology. In order to grasp the models design and restrict users to a limited set of features. This economists’ and engineers’ interventions, we draw on different poor design puts a priori limits to possible uses. In contrast, we traditions in sociology and anthropology (sociology of usage, argue that users can be “designed” as interested in and open to practice theory and STS) that enables us to analyse how users devices that concern them.

In the following parts, we quickly analyse how users, social acceptance and engagement are used in the different disciplines and how these conceptions I. SMART GRIDS AND MULTIDISCIPLINARITY frame possible uses. As part of the target 20-20-20 set by the European Union, the Walloon Region in Belgium has decided to fund the FLEXIPAC project to evaluate the potential of flexibility in II.

In this project, which spans over 2013-14, different scenarios to evaluate the potential of flexibility, i.e. we work as anthropologists and designers, along with partners shiftable loads for different types of buildings, heat pumps and who are engineers and economists. In order to collect occupancy profiles. Technical models are carried out on a consumption data, smart meters have been installed in 70 reference building that is used to simulate different households and 15 small enterprises.

For engineers, the user is a random variable renewable energy. Today, smart grid instruments are mainly which makes their models fluctuating. The user is thus reduced based on information, prices and technology. Aspects of to a set of parameters that emulate his actions on the inner environment, participation and community are hardly explored climate of the house: humidity, temperature and CO2 in smart grid projects.

ECONOMICS: USERS SHOULD BE RATIONAL management of their devices to external operators? We have In our project, economists (and electricity suppliers) seek to adopted a provisional definition of flexibility: curtailing or determine the potential and the cost of flexibility for heat pump shifting one’s consumption for the benefit of a upper level (i.e. systems. They seek to identify electricity pricing to encourage that makes sense and value to an aggregate level). The upper consumers to shift their heat pump loads to time where energy level can be the electrical grid, the provider, the environment, is cheaper. The study focuses on the development of a cost etc. model that would minimize the “societal costs” (i.e. the cost for In collecting data through interviews and observations, the the provision of energy for consumers), would comply with the social scientist is faced with a diversity of uses and users, and technical requirements and would propose a more transparent is required to summarise this information and translate it in a tariff, splitting the benefits of flexibility between the different useful language for the project partners.

The economist requires also that users make leave economists and engineers quite baffled. rational choice and respond immediately to signals. It is at this price that behaviours can be mathematised. It goes without V. DESIGN: PRACTICES AND ENGAGEMENT saying that in this model non-economic interests are not represented. Top down innovation is facing a lot of resistance to change. The economic criterion of social acceptance is that services Numerous usage studies demonstrate the difficulty for must be competitive. Market is the place where potential users engineers to convince the user to follow the “right gesture”, can just say whether they agree or not with the product in “original script” or “procedure” of using a device [5]. The task buying it or not. This shows that the economists’ conception of is further complicated because 1) there is not a standard user innovation supposes that the relative absence of user but a diversity of individuals; there is not a right gesture, but a acceptance during the early stage is a necessary condition for singular appropriation. 2) The device comes in the domestic the development of innovation.
