Interaction between charging infrastructure and the electricity grid : the situation and challenges regarding the influence of electromobility on mainly low voltage networks
This report summarizes the situation with knowledge and challenges regarding the large scale introduction of electromobility in the Swedish power grid. The content convers a range of systemic perspectives in terms of challenges and impacts that the fast-growing amount of charging associated with electromobility poses to the actual power system. From this, several important questions are addressed in order to predict the future positive and negative impacts of this. A description of electromobility in technological terms is given by presenting various configurations of electric vehicles, charging infrastructure and energy supply. The focus is placed on the possible impacts on the low-voltage networks, mainly exploring the power quality issues and grid hosting capacity. The following power quality issues are addressed: rms voltage (slow voltage variation, overvoltage, undervoltage, fast voltage variations), unbalance, waveform distortion (harmonics, interharmonics, and supraharmonics), and power system stability. The hosting capacity is examined to predict whether the charging demand from electromobility can be accommodated in the existing power system considering the involved challenges. Furthermore, the aspect related to the charging process and people’s travelling patterns under a stochastic point of view is analyzed. With the advantages that electromobility brings, it is noticeable that people will change the way they move around. Insights from this perspective make it possible to predict how the grid needs to change to accommodate the future needs. This report is the intermediate result, about 10 months after the start of the project.
