摘要
本文不区分控制变量和状态变量,以节点电压增量作为目标函数自变量。优化时从寻找一个合理初始点着手,用线性规划求解,使网损达到最小。由于不需计算灵敏度逆矩阵和采用松驰技术,本算法具有计算速度快、收敛性能好和占用空间少的优点。本算法的有效性在两个例网上得以显示。
Undistinguishing state variables from control variables, this paper considers the increment of node voltage as independent variables of objective function. The minimizing network loss is achieved through searching a proper initial operation point and adopting linear programming for solution. Since it does not need to calculate sensitivity matrix and the relaxation technique is used, this algorithm is advantageous to save computational time and memory space. The effectiveness of this methodology is demonstrated by two 1EEE system examples.
