线性规划在有功静态安全域中的应用

提出了一种以直流潮流模型为基础,将构成显式安全域超长方体每个分量的上、下限作为待求变量,并选取发电机有功调节量总和最大为目标函数,将有功静态安全域的模型化成一个线性规划模型直接求解的新方法。文中附有算例,计算结果验证了该方法的有效性。

Application of Linear Programming in the Steady - State Real Power Security Region

This paper presents a new method for analysis and computation of steady-state real power security region by linear programming. In this method based on the D. C load flow, the upper and lower bounds of the hyper-cuboid explicit steady-state security region are chosen as unknown variables. The objective function is the total amount of the adjustable generations with weighting factors.The model of the steady - state real power security region is changed into the proposed linear programming method for calculation. The numerical examples are tested on IEEE 6-bus and 30-bus sample systems. The computational results showed the proposed model and algorithm feasible and effective.
