考虑电压稳定约束的最优潮流Optimal Power Flow Considering Voltage Stability Constraints

摘要(Abstract):
采用指数负荷模型研究了有载调压变压器对系统最优潮流的影响。在阐述电压稳定性L指标的基础上,将L指标引入传统最优潮流中形成电压稳定约束的最优潮流,运用原-对偶内点法求解该模型。算例结果表明,该模型鲁棒性较好,能更加真实地反映系统实际运行情况。不同静态负荷模型对系统电压稳定性和经济性有一定的影响,系统电压稳定性的提高是以牺牲经济性为代价的,在考虑电压稳定性时,有载调压变压器的加入可以有效降低系统燃料费用,平抑系统有功出力和燃料费用的波动,将波动维持在一个较小的范围内。
