Embodiment Construction
[0121] Below in conjunction with specific accompanying drawing and case the specific embodiment of the present invention is further described as follows:
[0122] Electric vehicle charging station planning method based on voltage stability and charging service quality, the process is as follows figure 1 As shown, it specifically includes the following steps:
[0123] Step 1. Obtain the charging demand information of electric vehicles through the analysis of traffic starting and ending points combined with Monte Carlo simulation;
[0124] Step 1.1: Use Monte Carlo simulation to generate battery capacity cap for each electric vehicle according to formula (1), and calculate the mileage Ran before the state of charge reaches the threshold according to formula (2) ac ;
[0125]
[0126] where μ 1 and σ 1 are the mean and standard deviation of the standard normal distribution function, respectively.
[0127] ran ac =η×(SOC i -SOC c )×Ran mc (2)
[0128] In the formula...

The electric vehicle charging station planning method based on the voltage stability and the charging service quality comprises the steps of adopting Monte Carlo simulation to sample an electric vehicle traveling rule, obtaining charging information of an electric vehicle in combination with traffic starting and ending point analysis, and determining a candidate station address according to the charging reliability of an electric vehicle user; Comprehensively considering charging station construction and operation economy, system voltage stability, electric vehicle user charging queuing time and a charging service quality index, and establishing a comprehensive optimization model of charging station planning; And converting the multi-target problem into a single-target problem, and solvingthe model to obtain an optimal site selection constant volume scheme. According to the method, the rationality of the candidate station addresses of the charging station is ensured by applying the traffic start-stop point analysis and the charging reliability, a multi-objective planning model is established by taking the two attributes of the charging station as electric facilities and public service facilities into account, and the service quality index of the charging station is provided, so that the model has more practical significance.
Description
technical field [0001] The invention relates to the technical field of electric vehicle charging station planning, in particular to a planning method for electric vehicle charging stations based on voltage stability and charging service quality. Background technique [0002] Electric vehicles have the advantages of zero emission and no pollution, and their large-scale use will be further expanded. The planning and construction of charging stations will largely affect the promotion of electric vehicles. Unreasonable planning and configuration of charging stations will also have a serious impact on the economy and stability of power grid operation, as well as the convenience and reliability of user charging. Therefore, the popularization of electric vehicles must be based on scientific and reasonable planning of charging stations. [0003] Scholars at home and abroad have carried out research on the planning of electric vehicle charging stations from different angles, but the...
