  7. Abstract:
  8. Over the last few years, several economical and environmental reasons have caused many countries throughout the world to plan to replace conventional gasoline vehicles with different types of electric vehicles, and hence, it is anticipated that using these vehicles will quickly be developed in near future. Widespread use of electric vehicles calls for a comprehensive network of easily accessible charging stations being capable of replenishing their batteries. In this regard, municipal public parking decks, because of their characteristics, can be considered as proper candidates for installing charging equipment. However, as a large number of electric vehicles can be parked at a public parking deck, a considerable electric energy will be required to charge their batteries. Due to this high level of charging power demand, the appropriate operation of the parking deck is possible only if there is an efficient energy management system. In order to address this issue, this thesis proposes an energy management strategy with the main objective of maximizing the parking deck owner’s profit, which besides satisfying the electric vehicle owners’ requirements, considers the appropriate performance of the power system. In this regard, as the first step, the electric vehicles are only assumed as controllable loads which require electrical energy to charge their batteries, and based on this assumption, a charging control strategy is presented. In this step, different electricity tariffs which can be used to calculate the charging costs of the electric vehicles are studied, and also a new tariff is proposed. As the second step, the electric vehicles, because of their batteries, are assumed as energy storage resources which can return their stored electrical energy to the grid, and based on this assumption, a charging and discharging control strategy is presented. As the final step, it is assumed that the parking deck under study has also a number of photovoltaic panels, and based on this assumption, a comprehensive energy management strategy is proposed
