摘要:
采用地区电网无功综合效益优化模型,从经济运行角度,兼顾地区电网有功网损最小和因数达到要求值,使电网的年运行费用达到最小。优化算法将仿射变换内点法与简化分枝定界法(内点-分枝定界法)综合应用于优化过程中,计算结果表明它是一种有效的无功优化算法。

A method for optimizing VAR synthetic benefits based on local power system economic operation
YANG Su qin  CHEN Xing ying
Abstract:
With the objectives of minmizing power loss and meeting the power factor requirement of local power system,the model for optimizing VAR synthetic benefits of local power system is used to minimize the annual cost of power system economic operation.The optimization algorithm applies affine transform based interior point method and simplified branch bound method for reactive power optimization.The numerical result shows clearly its validity.
Key words:  economic operation,VAR optimization,power losses,affine transform based interior point method,simplified branch bound method
