  7. Abstract:
  8. Todays, thanks to the positive effects of electric vehicles, (against the vehicles which use patrol as their fuel), reduction of the Earth temperature and its climate change; the manufacturing, sale and use of electric vehicles experience a sharp increase. In addition to decreasing the air pollution, due to their abundant smart implications, they have been dramatically propagated. Massive use of these devices has raised the concern about the loss of the security which is indispensable part of the infrastructure. None of the past publications and works have taken the cyber-attack on the charging price rate and other data into account. In this thesis, charging methods of electric vehicles are identified, as well as the impact of any change in the charging prices on the costumers and power system operator behavior. A tri-level optimization model is utilized to cope with the issue. At the first level, the problem is studied from system planner’s point of view to reduce the total cost in order to locate the distributed generators at the optimum locations around the grid. At the second level, worst-case scenarios are presented by observing the problem from the attacker's perspective. In this stage, we inaugurate a state-of-the-art method for detecting any abnormality which none of the up-to-date works has considered. In this regard, a self-generated dataset is created by modifying the charging price in the California state and a common machine learning algorithms which are exploited to detect abnormalities with an accuracy of 98%. At the final stage, this problem is viewed from a system operator perspective, to be employed for enabling him/her to change the switch status in order to minimize the effects of the attack. In this thesis, the IEEE-123 bus distribution system is employed to verify the new proposed methodology. Due to application of false data detachment in this method, a 38% reduction observed in service interruption
