电力系统无功优化研究

Study on Power System Reactive Power Optimization

随着电力工业向"大系统、超高压、远距离、大容量"发展,电网结构日趋复杂,系统稳定性问题日益突出。通过无功优化来改善电压质量、降低运行网损以及提高系统运行的安全稳定性显得尤为必要。因此,对电力系统无功优化研究,具有理论意义,又有实际意义。而无功优化问题又是一个多变量、多约束的混合非线性规划问题,其变量既有连续变量又有离散变量,使得优化过程十分复杂。

With power industry＇s development towards ＂large-scale system, high pressure, tong distance and high-capacity＂, the power network is becoming more complex; the system stability issue is becoming increasingly prominent. It is necessary to use reactive power optimization to improve voltage quality, reduce operation network loss and improve security and stability of the operation system. Therefore, it is meaningful to study the power system reactive power optimization. Reactive power optimization is a multi variable, multi-constrained mixed nonlinear problem; there are both discrete variable and continuous variable which make the optimization process very complicated.
