Nowadays, Renewable Energy Sources (RES) are attracting more and more interest. Thus, many countries aim to increase the share of green energy and have to face with several challenges (e.g., balancing, storage, pricing). In this paper, we address the balancing challenge and present the MIRABEL project which aims to prototype an Energy Data Management System (EDMS) which takes benefit of flexibilities to efficiently balance energy demand and supply. The EDMS consists of millions of heterogeneous nodes that each incorporates advanced components (e.g., aggregation, forecasting, scheduling, negotiation). We describe each of these components and their interaction. Preliminary experimental results confirm the feasibility of our EDMS.
Modern demand-side management techniques are an integral part of the envisioned smart grid paradigm. They require an active involvement of the consumer for an optimization of the grid's efficiency and a better utilization of renewable energy sources. This applies especially in so called demand dispatch systems, where consumers are required to proactively communicate their flexibilities. However, a monetary compensation may not sufficiently motivate the individual consumer for a sustainable participation in such a program. The proposed approach uses a motivational framework leveraging the novel area of gamification, which applies well-known game mechanics, such as points and leaderboards, to engage customers in the system. This is accomplished by embedding a special scoring system and social competition aspects into a stimulating user interface for the definition and management of flexible energy demand. In a first user study, the system showed a high user acceptance and the potential to engage consumers in participation.
Abstract. The emerge of web services in Service-Oriented Architectures (SOA) within companies or at the global internet oers new ways for the creation of web applications. Even though the composition of services via business processes are covered by existing tools and solutions, concepts for a lightweight service consumption are still in a preliminary phase. The complexity of state-of-the-art SOA technology prevents users with limited IT skills getting easy access to web services and their oered functionalities. This paper presents a user-centric design approach to model and create simple service-based applications in a graphical way without being necessary to write any code.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
