[0061] ;
[0062] in, is the remaining dispatchable charging power of the current power grid, is the total power supply of the grid, is the current grid load.
[0063] In some embodiments, priority is given to intelligent charging of vehicles with high charging priority, so that their current charging power can be maintained to the maximum extent during peak load of the power grid to ensure their charging needs.
[0064] In some embodiments, step S303 may include but is not limited to steps S401 to S405:
[0065] Step S401: The vehicle with the highest charging priority is obtained as the currently adjusted vehicle, and the current charging power corresponding to the currently adjusted vehicle is obtained as the current charging power to be adjusted;
[0066] Step S402: When the current remaining dispatchable charging power of the power grid is greater than the current charging power to be adjusted, the current charging power to be adjusted is determined as the charging adjustment power corresponding to the current adjustment vehicle, and the current remaining dispatchable charging power of the power grid is updated based on the charging adjustment power corresponding to the current adjustment vehicle and the current remaining dispatchable charging power of the power grid.
[0067] Step S403: determining the total charging power corresponding to all vehicles except the currently adjusted vehicle, comparing the updated remaining dispatchable charging power of the current power grid with the total charging power, and generating a comparison result;
[0068] Step S404, determining the charging adjustment power corresponding to the remaining vehicles based on the comparison result, the current remaining dispatchable charging power of the power grid, and the charging status data corresponding to the remaining vehicles;
[0069] Step S405: When the remaining dispatchable charging power of the current power grid is less than the current charging power to be adjusted, the charging power is dynamically allocated according to the remaining dispatchable charging power of the current power grid and the current remaining charging time corresponding to each vehicle to determine the charging adjustment power corresponding to each vehicle.
[0070] In step S405 of some embodiments, the charging adjustment power corresponding to each vehicle is determined based on the current remaining dispatchable charging power of the power grid and the current remaining charging time corresponding to each vehicle. The charging adjustment power corresponding to each vehicle is calculated using the following formula:
[0071] ];
[0072] in, For the The charging adjustment power of each vehicle, For the The current remaining charging time of each vehicle, is the remaining dispatchable charging power of the current power grid, is the number of vehicles including the current adjustment vehicles, For the The current remaining charging time of each vehicle.
[0073] In some embodiments, step S404 may include but is not limited to steps S501 to S502:
[0074] Step S501: When the comparison result shows that the updated remaining dispatchable charging power of the current power grid is greater than the total charging power, the current charging power corresponding to the remaining vehicles is determined as the charging adjustment power;
[0075] Step S502 : When the comparison result shows that the updated remaining dispatchable charging power of the current power grid is less than the total charging power, the charging adjustment power corresponding to the remaining vehicles is determined based on the updated remaining dispatchable charging power of the current power grid and the current remaining charging time corresponding to the remaining vehicles.
[0076] In step S502 of some embodiments, the charging adjustment power corresponding to the remaining vehicles is calculated using the following formula:
[0077] ];
[0078] in, For the The charging adjustment power of the remaining vehicles is For the The remaining charging time of the remaining vehicles, is the updated remaining dispatchable charging power of the current power grid, is the number of remaining vehicles excluding the currently adjusted vehicles, For the The remaining charging time of the remaining vehicles.
[0079] In some embodiments, when the comparison result is that the updated remaining dispatchable charging power of the current power grid is greater than the total charging power, the current charging power corresponding to each of the remaining vehicles is maintained unchanged, and the current charging power corresponding to each of the remaining vehicles is determined as the charging adjustment power.
[0080] In some embodiments, for example, assuming that the total power supply of the power grid is 1000kW and the monitored current power grid load is 900kW, the current remaining dispatchable charging power of the power grid is: 1000kW-900kW=100kW.
[0081] Vehicle charging status: Assume that there are three electric vehicles charging, and their relevant information is as follows:
[0082] 1) Vehicle A: 30% charged, 70% remaining, 2 hours remaining, current charging power 50kW;
[0083] 2) Vehicle B: 50% charged, 50% remaining, 1.5 hours remaining, current charging power 60kW;
[0084] 3) Vehicle C: 20% charged, 80% remaining, 3 hours remaining, current charging power 40kW;
[0085] The charging priority of vehicles A to C is determined based on the current remaining charging time of vehicles A to C, specifically: vehicle B > vehicle A > vehicle C.
[0086] According to the charging priorities of vehicles A to C, vehicle B is determined as the currently adjusted vehicle, and the current charging power of vehicle B, 60kW, is obtained as the current charging power to be adjusted. The current charging power to be adjusted is compared with the current remaining dispatchable charging power of the power grid. 60kW<100kW, that is, the current remaining dispatchable charging power of the power grid is greater than the current charging power to be adjusted. The current charging power of the currently adjusted vehicle is maintained, and the current charging power to be adjusted is determined as the charging adjustment power corresponding to the currently adjusted vehicle, that is, the charging adjustment power of vehicle B is 60kW. According to the charging adjustment power corresponding to the currently adjusted vehicle and the current remaining dispatchable charging power of the power grid, the current remaining dispatchable charging power of the power grid is updated. The updated current remaining dispatchable charging power of the power grid is 100kW-60kW=40kW.
[0087] Determine the total charging power for all vehicles except the currently adjusted vehicle, which is 50kW + 40kW = 90kW. Compare the updated remaining dispatchable charging power of the current power grid with the total charging power to generate a comparison result of 40kW < 90kW, indicating that the updated remaining dispatchable charging power of the current power grid is less than the total charging power. Based on the updated remaining dispatchable charging power of the current power grid and the current remaining charging time of each vehicle, determine the corresponding adjusted charging power for each vehicle. Specifically, the adjusted charging power for vehicle A is 40kW * [2 / (2+3)] = 16kW, and the adjusted charging power for vehicle C is 40kW * [3 / (2+3)] = 24kW.
