摘要: 针对预测-校正内点法求解混合直流输电(hybrid HVDC)系统最优潮流(OPF)时可能存在过校正而导致的发散问题,提出了基于加权预测-校正内点法的hybrid HVDC系统OPF算法。该算法保留了预测-校正内点法的预测步骤,将校正步进行加权,动态选择了校正方向在总的牛顿方向所占的比例,比较好地解决了预测-校正内点法校正错误而不收敛的问题。算例仿真表明,对hybrid HVDC系统进行OPF计算,能使系统处于更经济的运行状态。通过对多个IEEE节点系统进行仿真测试,验证了加权预测-校正内点法的有效性和正确性。

Abstract: In solving hybrid HVDC system optimal power flow(OPF) problem, predictor-corrector interior-point method may cause over-correcting divergence. A weighted predictor-corrector interior-point method is proposed to solve diverge problem in this case. This algorithm retains predictor step of predictor-corrector interior-point method and selects corrector direction in total proportion of Newton direction dynamically. The numerical simulation result indicates hybrid HVDC system can operate in better optimization point. The accuracy and effectiveness of proposed method are demonstrated on multiple IEEE test systems.
