| 摘 要： | 在非线性原-对偶内点法的基础上引入了预报-校正技术,使改进后的非线性预报-校正内点法获得了较纯原-对偶内点法更大的迭代步长,从而加速了算法的收敛.应用该方法求解电力系统无功优化问题时能有效处理目标函数中的大量不等式约束.IEEE 14节点、IEEE 30节点、IEEE 57节点和IEEE 118节点系统的仿真结果表明,该算法收敛快、鲁棒性好.

| Abstract: | The predictor-corrector technology is applied to nonlinear primal-dual interior point method and a longer iteration step can be obtained by use of the improved nonlinear predictor-corrector primal-dual interior point method than pure primal-dual interior point method, so the convergence can be speeded up. Using the improved method for power system reactive power optimization a large number of inequality constraints in the objective function can be effectively dealt with. The simulation results from four test systems, i.e., IEEE 14-bus system, IEEE 30-bus system, IEEE 57-bus system and IEEE 118-bus system, show that the improved algorithm possesses fast convergence speed and good robustness. |
