    A consumer-orientated Architecture for distributed Demand-Side-Optimization
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Dethlefs, Tim; Beewen, Dirk; Preisler, Thomas; Wolfgang, Renz
    Demand-Side-Management (DSM) is one of the key applications in the future smart grid, creating a new degree of control in order to reduce losses and fluctuations caused by volatile distributed energy resources (DERs). To integrate the consumer side, several approaches like flexible tariffs, have been proposed and tested. However, many of these approaches not have been adopted widely yet because of the needed sophisticated (and often expensive) command and control infrastructures or their impact on the user comfort. In this paper an architectural approach for a lightweight demand-side-application will be proposed. Utilizing methods of peer-to-peer (p2p) networks and abstraction patterns the architecture will be enabling consumers to form spontaneous demand-side optimization networks in order to optimize their load and to provide energy services to the Smart Grid of the future. Because of the decentralized characteristic of the architecture, the aggregation instance does not need detailed information of the optimization network, while the approach is scalable.

    Scalable Integration of 4GL-Models and Algorithms for massive Smart Grid Simulations and Applications
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Preisler, Thomas; Balthasar, Gregor; Dethlefs, Tim; Renz, Wolfgang
    This paper presents a scalable integration approach for algorithms and models written in fourth generation (programming) languages for massive Smart Grid simulations as well as applications. While fourth generation languages (4GL) focus on rapid application development and the reduction of lines of code, they lack of integration and scalability features. Nevertheless, they are widely spread and often used by engineers. The scalable integration of such elements is achieved in this paper by wrapping the 4GL-models and algorithms with established web technologies like RESTful web services and load balancing. The provision of a seamless integration concept allows engineers to focus on rapid application development and liberates them from integration efforts.
