  7. Abstract:
  8. The usage of plugin hybrid electric vehicles has environmental benefits. However, the penetration of these components raises important concerns for grid planning. Thus, it is necessary to model the load change due to their charge to investigate the impact of these vehicles on distribution networks. For this reason, it is necessary to determine the specifications of these vehicles, such as battery charge and energy consumption on daily trips. In addition, the study of some behavioral patterns of these vehicles and some experts are necessary to complete the model.In this thesis, an active distribution network is planned using dynamic programming formulation. In this model, some buses are added to the distribution network on the planning horizon. The model's objective function is to minimize the operating costs of the distribution network, which consists of the investment cost of feeders and distributed generators, reliability costs of demand, the operation cost of distributed generations, and the cost of buying energy from the upstream network. Also, some new feeders and distributed generators are added to the network to cover the increase in demand along the planning horizon so that the limitations of network operation such as limitation of voltage drop of buses and feeder currents and limitation related to the amount of distributed generation are satisfied.. The base model has some non-linear equations, so the model is linearized using some of the linearization techniques. The final model is formulated as mixed-integer linear programming. Finally, the model was tested on 16-bus test systems in four scenarios with different levels of plugin hybrid electric vehicles penetration in the network using GAMS software
