Problems solved by technology
If electric vehicles are charged in low power consumption valleys, the peak-to-valley difference of the power grid can be reduced, the actual utilization rate of power distribution system facilities can be improved, and a positive impact is brought to the power grid; however, disorderly and random charging may lead to new power consumption peaks , increasing the burden on the power supply system
[0004] The charging of a large number of electric vehicles will also change the load structure and characteristics of the distribution network. The traditional urban grid planning guidelines may not be applicable to the scenario of large-scale access to electric vehicles. Changes in load distribution may cause local distribution transformers to Changes will result in changes in network loss and changes in network congestion
