Electric Mobility Should Be Linked to an Additional Expansion of Renewables: Six Questions to Wolf-Peter Schill

Electromobility in Germany: CO2 Balance Depends on Charging Electricity

The German government plans to significantly increase the deployment of electric vehicles. What impact would this have on the country’s power system and carbon emissions? This question was addressed as part of a European research project analyzing various scenarios up to 2030. One of the key findings of the study is that total annual power consumption of the four to five million electric vehicles (depending ...

Analyzing the Continuity of Attitudinal and Perceptional Indicators in Hybrid Choice Models

This paper addresses the continuity of attitudinal and perceptual indicators in hybrid discrete choice models and the main objective of this work is to compare the consequences of treating the indicators as continuous or ordinal outcomes, given different assumptions about the way in which these are stated. Based on tradition and for computational reasons, such indicators are predominantly treated as ...

The Potential of Electromobility in Austria: An Analysis Based on Hybrid Choice Models

This paper analyses the impact of the introduction of electromobility in Austria, focusing specifically on the potential demand for electric vehicles in the automotive market. We estimate discrete choice behavioral mixture models considering latent variables; these allows us to deal with this potential demand as well as to analyze the effect of different attributes of the alternatives over the potential ...

Power System Impacts of Electric Vehicles in Germany: Charging with Coal or Renewables?

We analyze future scenarios of integrating electric vehicles (EV) into the German power system, drawing on different assumptions on the charging mode. We use a numerical dispatch model with a unit-commitment formulation which minimizes dispatch costs over a full year. While the overall energy demand of the EV fleets is rather low in all scenarios, the impact on the system’s load duration curve differs ...

Power System Impacts of Electric Vehicles in Germany: Project Report

Im Rahmen des Projekts DEFINE untersuchen wir die Integration künftiger Elektrofahrzeugflotten in das deutsche Stromsystem für verschiedene Szenarien der Jahre 2020 und 2030 bei unterschiedlichen Ladestrategien. Wir verwenden ein numerisches Kraftwerkseinsatzmodell mit einer Unit‐ Commitment‐Formulierung, bei dem die gesamten Kraftwerkseinsatzkosten über ein komplettes Jahr minimiert werden. Elektrofahrzeugspezifische ...

Analyzing the Continuity of Attitudinal and Perceptual Indicators in Hybrid Choice Models

The main objective of this paper is to compare the consequences of treating the attitudinal and perceptual indicators of hybrid discrete choice (HDC) models as continuous or ordinal outcomes. Based on tradition and computational reasons, such indicators are still predominantly treated as continuous outcomes in practice. This usually neglects their nature (as respondents are normally asked to state ...

Power System Impacts of Electric Vehicles in Germany: Charging with Coal or Renewables

We analyze the impacts of future scenarios of electric vehicles (EVs) on the German power system, drawing on different assumptions on the charging mode. We find that the impact on the load duration curve strongly differs between charging modes. In a fully user-driven mode, charging largely occurs during daytime and in the evening, when power demand is already high. User-driven charging may thus have ...
