Fachbeitrag "Integration von eFahrzeugen in Stromnetze" in der Fachzeitschrift "NEUE MOBILITÄT"

Die Elektrifizierung von Fahrzeugen im Sinne einer nachhaltigen Mobilität schreitet voran. Elektrofahrzeuge ermöglichen eine direkte Nutzung des aus regenerativen Quellen stammenden Stroms. Eine Voraussetzung ist die Bereitstellung einer adäquaten Ladeinfrastruktur. Für Netzbetreiber ergibt sich die Herausforderung, die Fahrzeug-Ladeprofile und damit verbundenen Stromflüsse zu prognostizieren, die Netzinfrastruktur an verschiedenste Ladeszenarien anzupassen und Regeln für ein langfristig robustes Zusammenspiel von Elektrofahrzeugen, erneuerbarer Stromerzeugung und Stromnetzen in einem ökonomisch effizienten Rahmen zu schaffen. Im Projekt NEMO entwickelt ein internationales Forschungsteam aus Holland, Deutschland und Dänemark ein Modellierungs-Framework, um die genannten Fragestellungen zu untersuchen.

Analysis of the Exploitation of EV Fast Charging to Prevent Extensive Grid Investments in Suburban Areas

Voltage control decreases the need for conventional grid reinforcement: We analyze the extent to which voltage control strategies decrease critical voltage levels compared to uncontrolled charging of EV in suburban low voltage grids. If in the underlying grid at the same time both active and reactive power control is applied for all sub-scenarios the volume and frequency of power limitation is reduced and in most cases a power limitation of 2 kW satisfies the voltage boundaries.

Anticipation and simulative analysis of electric grid problems caused by electric vehicles

Electric vehicles (EV) are one element of the future transition towards a clean and sustainable energy system, since they can be powered by electricity generated by wind, photovoltaics (PV) and other renewable energy sources. With their ability of decentralized storage of electricity they can even contribute to solving the challenge of leveling out fluctuating generation by shifting demand or re-feeding electricity into the grid. For grid operators it is necessary to anticipate grid problems resulting from the new dynamic energy flows between EV, grid and renewables, and to contrive smart and cost effective measures counteracting such problems. A research team in the European project NEMO develops a tool suite able to simulate the grid impact of EV charging stations and helping to tailor technical solutions to different application cases.

NEMO – a novel techno-economic tool suite for simulating and optimizing solutions for grid integration of electric vehicles and charging stations

With an increasing use of electric vehicles (EV) grid operators need to predict energy flows depending on electromobility use profiles to accordingly adjust grid infrastructure and operation control accordingly. Tools and methodologies are required to characterize grid problems resulting from the interconnection of EV with the grid. The simulation and optimization tool suite NEMO (Novel E-MObility grid model) was developed within a European research project and is currently being tested using realistic showcases. It is a combination of three professional tools. One of the tools aims at a combined techno-economic design and operation, primarily modeling plants on contracts or the spot market, at the same time participating in balancing markets. The second tool is designed for planning grid extension or reinforcement while the third tool is mainly used to quickly discover potential conflicts of grid operation approaches through load flow analysis. The tool suite is used to investigate real showcases in Denmark, Germany and the Netherlands. First studies show that significant alleviation of stress on distribution grid lines could be achieved by few but intelligent restrictions to EV charging procedures.

New report online: Handling abnormal charging situations. Evaluation of tool application, manual and tool set reference

The report summarizes the findings of the “Abnormal charging” use case. These situations are characterized by irregular load requirements which occur only during limited time intervals that lead to singular charging requirements where the requested load profiles are untypical for EV prohibiting application of common grid design tools and methodologies. These situations are characterized by strongly varying load profiles with only limited long-term predictability. Any significant short-term change of the EV charging profiles leads to a serious technical problem. Typical examples are events where a larger number of people are gathering at one spot such as sports or festivals. The report describes how the NEMO tool suite was applied for three different show cases in order to derive implications for manuals for abnormal charging situations. Authors: Dr.-Ing.

Report: NEMO Showcase Designer and Simulation Tool Suite

The NEMO process for automized grid planning has been automated in the NEMO showcase designer. The function is implemented in the programming language R and is based on the sub-function design and calculation. Interfacing is possible via com-mand line or graphical user interface. The command line operation requires simulation settings and parameters to be defined within the NEMO showcase simulator script in R. The graphical interface version has basically the same functionality as a front end user inter-face where the parameter settings can be provided in a user friendly manner.
