基于配点法的参数化暂态稳定性约束的电力最优潮流分析

Optimal Power Flow Analysis with Parameterized Transient Stability Constraints Based on Point Assignment Method

为实现针对暂态稳定约束最优潮流的精确描述,提出一套参数化TSCOPF模型。通过该模型来判定电力系统中可变参数与TSCOPF解之间的定量关系。借助可变参数的多项式表达式来逼近参数化TSCOPF的最优解。在此基础上,只需在参数化TSCOPF中代入电力系统的可变参数即可取得符合暂态稳定性的最优控制方案。

In order to realize the accurate description of optimal power flow with transient stability constraints,a set of parametric tscopf model is proposed in this study.Through this model,the quantitative relationship between variable parameters and tscopf solution in power system is determined.The optimal solution of parameterized tscopf is approximated by the polynomial expression of variable parameters.On this basis,the optimal control scheme in line with transient stability can be obtained by substituting the variable parameters of the power system into the parameterized tscopf.
