The invention discloses an electric power regulation and control method and belongs to the technical filed of electric power system. The method comprises the steps: acquiring monitoring data of a to-be-regulated-and-controlled position; according to a three-dimensional topographical map, acquiring relevant elevation information, landforms information and building information of the to-be-regulated-and-controlled position; according to the monitoring data, the elevation information, the landforms information and the building information, determining a candidate regulation and control strategy of the to-be-regulated-and-controlled position; pre-executing the candidate regulation and control strategy in the three-dimensional topographical map, and displaying pre-execution effect; and determining a final regulation and control strategy according to the pre-execution effect and the candidate regulation and control strategy. According to the invention, the candidate regulation and control strategy of the to-be-regulated-and-controlled position can be determined according to the monitoring data, the elevation information, the landforms information and the building information, the final regulation and control strategy can be determined according to the pre-execution effect and the candidate regulation and control strategy, then the monitoring data, the elevation information, the landforms information, the building information and the execution effect can be comprehensively considered for determining the regulation and control strategy, and the feasibility of the regulation and control strategy can be improved.
