1. Power control strategy of electric vehicle charging socket in charging station
During the peak period of power consumption, the grid dispatching department will provide a power value that the charging station can consume, which may be lower than the installed capacity of the charging station, and how the charging station will distribute the limited total power in the case that the total output power is not allowed to exceed the limit value.
2. Power control system structure of electric vehicle charging socket in charging station
The power control strategy of the charging station is to predict the charging power of the electric vehicle connected to the charger, then make statistics on the output capacity of the charger, and formulate the corresponding distribution strategy according to the limit value given by the grid dispatching and the current output, so as to realize the control of the total charging power of the charging station. On the basis that the total power output of the charging station should not exceed the limit value sent by the dispatching department of the power grid, three control strategies are proposed: the power control strategy based on average distribution, the queue power control strategy based on the shortest charging time and the coordinated power control strategy based on the maximum utilization rate.
3. Power control policy in average distribution mode
In order to make the total power of the charging station not exceed the limit value set by the grid, the simplest way is to take the average distribution of the power control of the charging station, that is, the total power allowed to be consumed by the charging station is evenly distributed to each charger to achieve the purpose of limiting the total power.
