Conference Paper
Conventional methods of on-load tap changer transformer (OLTCs) based voltage control in low Voltage (LV) distribution grids turn out to be more and more difficult. This is due to constant growth of distributed infeed (e.g. from photovoltaic systems) and the emergence of new electric load types (e.g. electric cars, heat pumps). New concepts to face...
Technical Report
Zielsetzung der Smart-Grid-Technologieroadmap Die vorliegende Technologieroadmap ist ein zentraler Beitrag zum – vom bmvit initiierten – Strategieprozess Smart Grids 2.0. Sie behandelt die kurz- und mittelfris-tigen Entwicklungsschritte zur Umsetzung von Smart Grids bis hin zur industriellen Entwicklung und Imple-mentierung marktfähiger Produkte un...
Conference Paper
Full-text available
Die vermehrte Integration dezentraler Erzeuger in die europäischen Verteilernetze führt zu einer Transformation der europäischen Energieversorgung. Zukünftig wird es vermehrt zu Konflikten zwischen überregionalen Marktaktivitäten und (technischen) lokalen Netzgrenzen kommen. Eine Möglichkeit zur Lösung dieser Konflikte besteht in der Schaffung eine...

"Flexibility Operator" - Marktbasierter Ansatz für die Koordination von Markt und Netz
Conference Paper
Full-text available
In order to compare the impact of passive (like network restructuring) or active (like on-load-tap-changer) grid management measures a novel tool was developed, which performs specific load flow benchmarks tests using synthetic daily load and infeed profiles. In this paper first preliminary results of the analysis of a real urban medium voltage dis...
Conference Paper
Upcoming challenges for LV grids include a high penetration of distributed energy resources and electric vehicles. The project “DG DemoNet — Smart LV Grid” aims to enable an efficient and cost effective use of existing grid infrastructures based on a three-step concept: intelligent planning, on-line monitoring and active LV grid management. Communi...
Conference Paper
Full-text available
The subject of this paper is to describe the method newly developed within the research project ISOLVES (Innovative Solutions to Optimize LV Electricity Systems). The objectives are to study LV grids in detail and to close gaps of knowledge about impacts on voltage levels caused by asymmetric load or feed, and real grounding systems. Therefore a sm...
Conference Paper
Full-text available
According to low cost smart meters requirements a simple method providing weekly basic statistical information about voltage levels at costumer's sites was applied. The results from the meters in nine low voltage grids are presented and discussed in this paper. Lowest minimum but also highest maximum voltage values were observed at sites away from...
Conference Paper
Full-text available
Within this paper the goals and dedicated results for building the "National Technology Platform - Smart Grids Austria" are described and presented in detail. The "National Technology Platform - Smart Grids Austria" will prepare a network for relevant Austrian players in the area of Smart Grids and serve as competent discussion and implementation p...
Conference Paper
Full-text available
While distributed generation (DG) from renewable energy resources is seen as key element of future energy supply, current electricity grids are not designed to integrate a steadily increasing share of distributed generators. The hierarchical network topology was designed for unidirectional power flows and passive operation. In order to avoid excess...
Article
Full-text available
For the integration of a high amount of distributed genera-tion fundamental changes in electricity network operation are required. For avoiding expensive extension of grid capacity an intelligent electricity infrastructure is needed. That means to design and operate electrical distribution grids with intelligent approaches as for example some proce...
