摘要：
The minimum total supply capability is the dual index of the maximum total supply capability，they are respectively located at the lowest point and the highest point of total supply capability curve. The definition，mathematical model，solution method，and application method of minimum total supply capability are proposed. The mathematical model of minimum total supply capability is established，which is a linear programming model with the minimum total load on the strict security boundary as the objective function. A solution method based on the maximum redundancy equation is proposed for obtaining the working points with the minimum total supply capability. Aiming at each boundary with minimum total supply capability，the method adds the constraints that the redundancy equals to the maximum redundancy into the boundary constraints for forming the maximum redundancy equation，and the expressions of minimum total supply capability points on each boundary are obtained by solving the equation. The final result is obtained by the union of all the expressions of minimum total supply capability points. The correctness of the proposed model and method is verified by the example results. © 2024 Electric Power Automation Equipment Press. All rights reserved.
