基于预测–校正内点法ATC计算

20世纪70年代,电力工作者开始对系统区域间的可用输电能力(Available Transfer Capability,ATC)进行研究。在联邦能源管理委员会(Federal Energy Regulatory Commission,FERC)下达要求输电网的运行单位需计算ATC的命令之后,ATC的研究受到了广泛的关注。快速、可靠地评估ATC对系统的输电可靠性和电力市场交易顺利进行有着重要的作用。基于预测校正内点法计算速度快、鲁棒性好、快速收敛等优点,将预测校正内点法(Predictor-corrector Primal-dual Interior-point Method,PCPDIPM)应用于电力系统ATC计算;通过对模型进行仿真分析,与传统原对偶内点法(Primal-dual Interior-point Method,PDIPM)计算ATC进行比较,验证模型的实用性和算法的有效性及快速收敛性。

ATC Calculation Based on Predictor-corrector Primal-dual Interior-point Method

In the 1970s,electricians began to study available transfer capability (ATC) between system areas.ATC research has received extensive attention after the Federal Energy Regulatory Commission (FERC) issued an order requiring the operator of the transmission grid to calculate ATC.Rapid,reliable ATC evaluation plays an important role in the transmission reliability of the system and smooth conduct of electricity market transactions.Considering advantages of predictor-corrector primal-dual interior-point method (PCPDIPM) such as quick calculation,good robustness and fast convergence,PCPDIPM was applied to ATC calculation for the electric power system.Model simulation analysis and comparison with traditional PDIPM ATC calculation verified the practicability of the model as well as the validity and fast convergence of the algorithm.
