New technologies provide a much clearer view on the electricity grid and its processes, mainly due to the fine-grained and near real-time acquisition of data as well as assessment of it. The huge amount of information will include additional technical data beyond the traditional metering information for billing purposes. This may give rise to a new generation of tools that rigorously monitor residential endpoints. Such monitoring may assist towards rapidly identifying problems and decrease the time to resolve them. Currently, a real-time view of the grid state is done by specialized equipment, but their costs combined with their need to be widely deployed, is a limiting factor. Today's modern communication approaches coupled with high-performance analytics can be used in complex system monitoring and assessment. We argue how a large network of distributed smart meters can be used for analytics of the smart grid, based on our experiences in developing a smart metering platform that is currently monitoring approximately 5000 real smart meters. We analyse and discuss the results stemming from the data being streamed to the platform, and show how new insights can be obtained with respect to power quality.","PeriodicalId":244881,"journal":{"name":"2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122767488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the increasing connectivity, the power and cyber systems become more interdependent. Models of the interactions are needed between the power devices and information and communication technology (ICT). A broad range of cyber attacks has become a serious concern. Cyber attacks must be simulated to analyze the consequences on the power grid. Thus, the cyber system must be modeled explicitly and integrated with the power grid model. This paper describes the development and simulation of a novel co-simulation framework that integrates both the cyber and power systems. The objective is to implement the ICT model for real-time interactions with both the power grid and transmission operator. Different industrial grade environments have been developed to simulate the cyber-power interactions. ICT events that may affect the stability of the grid, e.g., cyber attacks, are simulated at the cyber system layer, and their impact analysis is conducted at the power system layer. The proposed co-simulation framework is validated with the IEEE 39-bus system.","PeriodicalId":244881,"journal":{"name":"2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128965481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A further target was to maximize the own consumption of the generated electricity by implementing a storage system. The house was to be built in Berlin as a showroom for public. For a period of 15 months (March 2012 to May 2013) a family of four is testing the suitability for daily use. Since the design of such a house requires knowledge in many fields, universities were asked to participate in the competition. The goal was not just to maximize the efficiency, energy output or own consumption by optimization, rather an attractive building was to be designed including an intelligent energy concept.","PeriodicalId":244881,"journal":{"name":"2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129082875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Smart Grid, the coordination of new actors and monitoring of new business processes, such as Active Demand and Electric Vehicles is non-trivial. These new actors and related business processes change the landscape of power grid from traditional passive Demand Side Management of loads to active customers connected in Active Distribution Grid. Smart Grid operations require monitoring and coordination between high-level business requirements and low-level infrastructure affordances. To support such perspectives of the power grid an additional ICT infrastructure supplementing traditional SCADA systems is required. We argue that to enable and validate end-to-end interoperable solutions a new tool is required. In this paper we introduce Service Level Agreement as one such a tool, supporting design and implementation of well-coordinated interoperable information flows and ensuring shared agreed-upon situation awareness among stakeholders.

The energy balance in the hybrid system is obtained by regulating the dc-bus voltage. In this study, all the elements can ensure the stability of the DC-bus voltage and the grid interventions are reduced. The control strategy is a rule-based strategy where a set of rules are defined and implemented using state machines. The novelty in this strategy is that there is no specific communication network between the elements of the system, the value of the DC-bus voltage is the only information that allows the several elements to interact. This condition permits to easily plug or unplug an element in the system without changes in the control scheme. The system configuration, the control method, the simulation results, analysis and future perspectives are all presented.","PeriodicalId":244881,"journal":{"name":"2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125783152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work a mathematical impedance model of a Lithium-ion battery with high dynamics for simulation of loads due to driving cycles and battery-to-grid applications as well as parameterization and validation of the model are presented. The model approach is based on an equivalent circuit. Parameterization of the model is done at many different operating points to assess the dependencies of the parameters on different battery states and model inputs. Both for high dynamic impacts and static periods simulation of terminal voltage shows good results in the considered operational range. The model is real time capable and suitable for robust control.
