Active distribution substation capacity control system and method

The present invention is active distribution substation control method and system capacity, on the one hand, consider the uncertainty of the load, analyzes the overall power load, the load can participation schedule grid, on the other hand, consider the case of a grid distributed energy output, DER trusted output power value is calculated based on the maximum load power grid and the predicted value output distributed trusted energy value, to calculate the total capacity of the substation in plan, and then the total capacity of the substation in planning, distribution substation capacity control. Throughout the process, take full account of the uncertainty of load cases and distributed energy output to ensure accurate calculation of the total capacity of the substation planning, thereby enabling accurate control of the power grid substation capacity, to ensure the safe operation of the power grid and efficient use of resources.
