Probabilistic Allocation Of Parking lots In Distribution Network Considering Uncertainty.

In this paper, parking lots with bidirectional power flow capability, is used as an achievements of smart power systems. Based on operating conditions, electric vehicles can be considered  as a load  or generator. For optimal operation of power systems, allocation of these novel units is also necessary same as other distributed generation. In this paper, an optimization problem is  proposed for allocation of electric vehicles parking lots. Loss reduction and reliability improvement are considered as two  main components of this allocation problem cost function. Because of uncertain in electric vehicle grid connection, modeling of  these probabilistic units is necessary to determine optimal size and location of  parking lots. There-fore, in this paper electric vehicle’s generated power is modeled by  Markove Chain. Markove Chain analysis is based on passengers’-trip data such as trip start and end time. Simulation  results show that installation of electric vehicle parking lots depends on many factors such as availability of electric vehicles as well as the electricity price. Also, it is shown that by taking enough incentive for electric vehicles owners, optimal size and location of parking lots  has a considerable benefit for distribution system companies.
