基于最优潮流方法的传输容量计算研究

OPF BASED TRANSFER CAPABILITY CALCULATION

可用传输容量计算已成为电力市场研究的一个重要部分,而总传输容量又是可用传输容量计算的基础。该文在介绍可用传输容量计算的基本概念、计算原则的基础上,建立了基于最优潮流(OPF)的总传输容量计算模型,提出了6种区域间传输容量计算目标函数,并通过定理证明了在一定条件下这六种目标函数计算的等价性。文中通过对IEEE-30节点系统进行的仿真计算,验证了基于OFP计算总传输容量的可行性,同时也通过实际算例验证了所提出定理的正确性。

The calculation of Available Transfer Capability (ATC) has become an important part of the research on the power market, and the calculation of Total Transfer Capability (TTC) is the foundation of ATC. This paper introduces the essential conception and calculating rules for ATC. The OPF based TTC calculation model was established, in which six different object functions were presented. A theorem gives proof of the equivalence of the six object functions used to calculate TTC under specific conditions. This paper testifies the feasibility of OPF based TTC calculation by IEE-30 bus system and proves the validity of the theorem through practical examples.
