Electric vehicles (EVs) can be an important building block of future power systems due to the flexibility of the charging process. In liberalized power systems, the objectives of using this flexibility vary for different actors in the system. In this paper we formulate the optimization problem of EV charging from the perspective of three different actors: 1) consumers (represented by an aggregator),...
The impacts of EV charging on electricity grids is becoming an increasingly important subject of study, but detailed knowledge about the future charging profiles of EVs appears to be missing. In this study we construct EV charge profiles based upon a large dataset of driving patterns. We consider both controlled and uncontrolled charging scenarios, where the main rationale of the controlled charging...
Reductions in greenhouse gas emissions are a strong incentive for the large scale introduction of electric vehicles. Studies that quantify these environmental benefits have to incorporate emissions caused by generating the electricity used to power the vehicles. We show that an approach that uses the average CO2 intensity of power generation is inaccurate and one needs to consider the generation capacity...
This papers investigates the impact of electric vehicle charging on residential low-voltage networks. The analysis is based on real life data of both driving patterns and a large number of electricity networks. The focus is on comparing uncontrolled an controlled charging scenarios. The results indicate that a significant number of LV-transformers will be overloaded if no charge control is applied...
