Such efforts are core enablers for electric vehicles being used for demand side management. Hence this work investigates the ability to adapt the {EV} charging process in near real-time in case of grid violations through {V2G} communication by rescheduling or demand-limit renegotiations. The overall benchmark scenario is defined by the identified {V2G} rescheduling processes in case of unpredicted critical exceedance of operational grid constraints.}, number = {1}, journal = {International Journal of Interoperability in Business Information Systems}, author = {Ruthe, Sebastian and Schmutzler, Jens and Rehtanz, Christian and Wietfeld, Christian}, month = sep, year = {2011}, pages = {33--44} }, @article{rohjans_standardized_2011, title = {Standardized Smart Grid Semantics using {OPC} {UA} for Communication}, volume = {6}, issn = {1862-6378}, abstract = {As many roadmaps and studies were developed focusing on smart grid standardization a set of core standards was identified. Some of them specify own data models and thus, create a need for harmonization to enable interoperability in terms of communications. On the level of data model integration, two data models play key roles in the future smart grid. On the one hand the Common Information Model and on the other hand {IEC} 61850-based models. Both were identified as core standards and are part of the {IEC} {TC57} Seamless Integration Architecture, another recommended standard. In this contribution the {OPC} Unified Architecture, which is also a core standard specifying a server-client-architecture, is used to harmonize the two mentioned data models based on a common access layer. This leads to higher interoperability for, e.g., Energy Management Systems, Distribution Management Systems or {SCADA} systems.}, number = {1}, journal = {International Journal of Interoperability in Business Information Systems}, author = {Rohjans, Sebastian and Piech, Klaus and Mahnke, Wolfgang}, month = sep, year = {2011}, pages = {21--32} }, @article{lund_mobile_2011, title = {Mobile Power Information System}, volume = {6}, issn = {1862-6378}, abstract = {This paper investigates different methods for giving users informative feedback on their electricity consumption. After comparing different methods for giving feedback a method comparing power consumption and temperatures is chosen. The purpose is to let power consumers find out how much changes in temperatures affect their consumption. A prototype mobile application has been developed and tested on the Android platform. The application retrieves temperature values and compares this to the consumption of the users. This gives the users a heating efficiency value that describes the amount of electricity used for heating. This is presented with graphs and corresponding values to the users. The results so far are promising, and future work includes a more large scale evaluation by real users.}, number = {1}, journal = {International Journal of Interoperability in Business Information Systems}, author = {Lund, Kristian and Krogstie, John}, month = sep, year = {2011}, pages = {7--20} }, @article{rohr_using_2011, title = {Using {CIM} for Smart Grid {ICT} integration}, volume = {6}, issn = {1862-6378}, abstract = {The {eTelligence} project explores and demonstrates various smart energy grid ideas by using modern {ICT} (information and communications technology). For this purpose, many new and heterogeneous types of smart grid systems have to be developed and integrated, such as a regional energy market, distributed energy management systems, and an advanced metering infrastructure. The future interaction scenarios of such new systems are still topics of research, which calls for an architecture easily supporting future changes. The integration capabilities of the {eTelligence} {ICT} architecture are based on standardized communication, especially using {IEC} 61970/61968 {(Common} Information Model, {CIM)} and an easily extensible market product description language also realized with {CIM.} Additionally, we present a process model for using {CIM}, and report our experiences from using {CIM} for integration.}, number = {1}, journal = {International Journal of Interoperability in Business Information Systems}, author = {Rohr, Matthias and Osterloh, Andre and Gründler, Michael and Luhmann, Till and Stadler, Michael and Vogel, Nils}, month = sep, year = {2011}, pages = {45--61} }
