Abstract:

A fuzzy control model for coordinated and orderly charging management of electric vehicle network under reservation mechanism is proposed.Firstly,the travel chain model of electric vehicle user behavior is constructed,and the Markov process of electric vehicle travel between different destinations is simulated by probability transfer matrix.Secondly,according to the distribution network load forecasting curve and electric vehicle reservation situation,collaborative management is carried out according to the distribution network load margin and electric vehicle charging demand.The charging power of electric vehicle is calculated dynamically.Finally,a simulation example is given to verify the proposed model and algorithm.The results show that the orderly charging management of vehicle network cooperation in this paper can reduce the peak valley difference of distribution network power,reduce the fluctuation of charging power and reduce the charging cost,and the synergistic effect is remarkable.

Key words: EV vehicle grid cooperation, orderly charging management, travel chain, fuzzy control, peak valley difference
