Title  Study on the influence of the load characteristic of      distribution network and the optimization strategy of electric vehicle charging and discharging     

Abstract One of the effective ways to reduce the traditional energy consumption and environmental pollution is to develop electric vehicles。 The number of electric vehicles is increasing, and the charging and discharging load of the electric vehicle will affect the load characteristics of the power grid。

The electric vehicles at home and abroad research status, electric cars pided into four categories, discusses the factors of five of the electric vehicle load characteristics trip characteristics, ownership, charging mode, charge mode and battery characteristics。

Analysis of various types of electric vehicle travel characteristics,The Monte Carlo method is used to simulate the all electric vehicle charging and discharging load characteristics, and through specific examples to simulate the impact of electric vehicles on the distribution network daily load curve, analyzes the influence of electric vehicle charging and discharging load on the load characteristics of the power grid, by means of regulation to be guided。

Discussed concentrated charging and discharging time control and the grid and automotive bidirectional communication control (V2G) the two optimizing charge and discharge control strategy, using the particle swarm algorithm to optimize the load curve, it is pointed out that the V2G method can effectively improve the load characteristics。
