摘要：

Electric vehicles have incomparable advantages over traditional vehicles in terms of energy saving and emission reduction and promoting the “dual carbon” process. However, disordered charging of large-scale electric vehicles may aggravate the load fluctuation of distribution network and even cause safety problems such as low node voltage. This paper proposes a charging guidance strategy for traveling electric vehicles considering the safety of distribution network operation. First, based on the original load and node voltage of the distribution network, a sub-regional time-of-use price pricing model is established to establish a correlation between the electricity price and the load situation. Secondly, based on the formulated electricity price, the preparatory scheduling for charging behavior of Eelectric vehicles in different charging regions is put forwad. The principle of scheduling is that the charging cost of electric vehicles is the lowest, so as to guide electric vehicles to charge in the load valley and participate in the load optimization of the distribution network. Thirdly, the sum of the weights of charging cost, total travel time, and travel distance is set as the minimum to establish a selection function for the electric vehicle charging station, thus charging stations and plans of the optimal driving path for electric vehicles can be recommended, and the user economy and the operation safety of the distribution network can be optimized. Finally, the modified IEEE 33-node distribution network is taken as an example to verify that this strategy can effectively improve the travel satisfaction of electric vehicle users and take into account the operation safety of the distribution network. © 2023 Science Press.
