基于内点法的交直流混合系统可用输电能力计算

提出并建立了交直流混合系统可用输电能力优化计算模型，该模型中的混合系统可以包含两端直流系统或多种结构的多端直流系统，模型通用性强。运用非线性原 — 对偶内点法求解模型，在求解过程中，对简约修正矩阵进行行列变换，形成了一种便于存储和编程的数据结构，提高了计算效率。以修改的IEEE 30节点混合系统为算例进行验证，仿真计算表明在换流站进行无功补偿对提高可用输电能力有明显作用，同时也验证了所提出的模型和算法的合理性和有效性。

Available Transfer Capability Calculation for Hybrid AC/DC Systems Based on Interior Point Method

This paper presents an optimization model for calculating the available transfer capability(ATC)of hybrid AC/DC systems.The hybrid systems can include either two-terminal DC systems or multi-terminal DC systems.The nonlinear primal-dual interior point method is used to solve this model.To increase calculation efficiency,a reduced correction matrix is derived.By exchanging its rows and columns,a data structure convenient for storing and writing programs is constructed.A modified IEEE 30-bus hybrid system is ...
