Research on Load Capacity Improvement of Electric Vehicles Based on Orderly Charging

As the environmental pollution caused by fossil energy consumption becomes more and more serious, the development of electric vehicles has received attention, so it is important to study the carrying capacity of the power system for electric vehicle charging load for practical guidance. The electric vehicle charging load is simulated by Monte Carlo. The maximum load capacity and node voltage deviation are selected as the operating constraints. The total electric load of the industrial park under different electric vehicle scales is simulated with the actual lines in Jiangsu Province as an example. The key reasons for limiting EV access are analyzed according to the parameters of the operating limiting conditions at the maximum EV scale. The impact of distributed PV access scale on the EV carrying capacity is simulated. The results show that the access to an appropriate amount of distributed PV can help alleviate the voltage dips at the nodes of the industrial park caused by the access of electric vehicles, and make the system operate safely and stably.
