    Darstellung des Konzeptes - DMA Decentralised Market Agent - zur Bewältigung zukünftiger Herausforderungen in Verteilnetzen
    (INFORMATIK 2015, 2015) Thomsen, Jessica; Hartmann, Niklas; Klumpp, Florian; Erge, Thomas; Falkenthal, Michael; Kopp, Oliver; Leymann, Frank; Stando, Sven; Turek, Nino; Schlenzig, Christoph; Schwarz, Holger
    In der vorliegenden Veröffentlichung wird ein Konzept für einen neuen Marktakteur im Strommarkt vorgestellt, der im zukünftigen Smart Grid als Aggregator und Planer fungieren kann. Dieser Decentralised Market Agent - DMA - soll die Informationen aller vorhandenen Erzeugungsund Speicheranlagen, Lasten und Netzinformationen auf Verteilnetzebene aggregieren sowie mit lokalen Akteuren und an den zentralen Märkten agieren um einen kostenoptimalen Betrieb und Ausbau des Systems Verteilnetzes zu realisieren. Zur Handlungsfähigkeit dieser neuen Marktrolle bedarf es hochauflösender Messungen im Verteilnetz und einer \?real-time“ Aufbereitung der Messdaten. Im vorliegenden Paper sollen das Konzept sowie die notwendigen Bausteine zur Erreichung der Handlungsfähigkeit des DMA vorgestellt sowie die zukünftig geplanten Untersuchungen erläutert werden. Die detaillierte Entwicklung des Konzepts sowie weiterführende Analysen sind Teil des Projektes NEMAR - Netzbewirtschaftung als neue Marktrolle, gefördert durch BMWi im Rahmen der Forschungsinitiative Zukunftsfähige Stromnetze.

    MESAP — A Co-operative Modelling System for Sustainable Local Energy and Environmental Planning
    (Sustainability in the Information Society, 2001) Schlenzig, Christoph; Steidle, Thomas
    Since the deregulation of German energy markets 1998 we can observe diverging planning interests and priorities of the local communities on one side and the local energy utilities on the other side. This seriously endangers the consensus in local energy planning achieved in the past which will be crucial in order to identify and implement effective greenhouse gas (GHG) mitigation strategies. This paper presents a co-operative planningapproach which embeds systems analysis into a well structured communication, mediation and learning process for decision making. This process is supported by the cooperative modelling systemMESAP, a software for energy and environmental planning, which integrates different energy models with an energy information system. This allows to combine traditional local energy planning with the more business oriented view of the utilities. The specific design of MESAP allows for a continuous "sustainable" planning and monitoring similar to business tools for accounting and controlling in companies.

    The MESAP Software for the German Emission Inventory
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Schlenzig, Christoph
    Emission reporting is a complex task. Large quantities of data have to be handled. They come from different sources and are communicated through a heterogeneous variety of means and tools. As a consequence they need a high degree of manual treatment which opens up the door for many types of errors. Since most of the reporting is done with Excel, the degree of data redundancy is high, each spreadsheet containing a copy of the original figures. Data flow, data processing and the calculations performed are rarely documented which makes it hard to verify the reported data. The German central system of emissions CSE was designed to achieve the five objectives of emission reporting: transparency, consistency, completeness, comparability and accuracy of the reported data. The requirements were to store time series with different time resolution, to quickly retrieve data and to easily create user defined views on the data. Finally the reporting was to be done using MS Excel format. CSE speeds up data processing and improves the documentation of data and calculation procedures. CSE offers a better management and accessibility of the time series data and allows even to open up this treasure via Internet. The data is well protected and documented in a central database. CSE gives the staff versatile analysis capabilities and lets them create reports in a well known fashion – still with Excel, but with a link to the database. The different steps from collecting new data up to publishing reports are automated as much as possible. CSE is built using the MESAP software technology, which enables the agency to profit from new developments and new functional modules at low cost.
