Abstract

In the last few decades, humankind has been concerned with finding a feasible way of coping with the expected future increase in the demand for electricity, while reducing the emissions of pollutants to the atmosphere. Many governments are investing in the development of new technologies, and it is believed by many experts in the field that a potential solution for these problems is to replace the internal combustion engine automobiles with Electric Vehicles (EVs). The energy storage in their batteries and the potential connection of thousands of EVs to the distribution grid could greatly help with its operation while providing Vehicle-to-Grid (V2G) reactive power support. The aim of this thesis is to analyze the inclusion of different scenarios of EV penetration to a simulated distribution grid with 22 nodes, using the computing program Matlab. In every scenario, the influence of the different locations of the EVs in the grid will be examined according to their reactive power support and the voltage profile regulation. Additionally, all daily timeframes will be evaluated regarding the influence of different EV penetration scenarios on the voltage profiles of the 22-bus distribution network according to the location of the EVs, the number of EVs available and their charging patterns. The existing residential load variations over a 24 hour cycle as well as realistic EV residential parking occupancy were also taken into account when analyzing two different charging scenarios.
