基于原—对偶内点法的二次电压—无功功率优化

基于原－对偶内点法对电力系统的电压－无功优化问题进行了分析，首先对原－对偶内点法进行了扩展，使之能处理电压－无功优化控制中大量不等式约束；此外，提出了一种新的壁垒参数和步长的控制策略，并采用了一种有效的预测－校正方法来提高算法的收敛速度。实际电网中优化计算表明，原－对偶内点法可有效地解决大规模电网的电压－无功优化问题。

Quadratic Voltage/Reactive Power Optimization Based on Primal Dual Interior Point Method

This paper presents a quadratic voltage/reactive power optimization method based on a path following primal dual interior point algorithm. A predictor corrector technology is applied in the algorithm and, a new method to select the computation step size and to update the barrier parameter is developed. The proposed method can effectively deal with inequality constraints which is more important in on line voltage reactive power optimization. Test in a practical power system demonstrates that the developed method is effective and accurate.
