摘要
在电力市场环境下,可用传输容量(ATC)是反映输电线路可用于交易的剩余容量的重要指标。文中以最优潮流为基础,采用Benders分解方法将考虑静态安全约束的ATC计算问题分解为一个基态主问题和一系列与各预想事故有关的子问题。主问题用来处理基态潮流和相应约束以及由子问题所返回的Benders割(cut)约束,而各子问题用来处理各预想事故和形成相应的静态安全约束。文章给出了相 应的数学模型,并提出了两种改进的求解策略。4节点和IEEE30节点系统的计算结果表明了该方法和求解策略的有效性。
In power market environment, available transfer capability (ATC) is an important indicator of the further usable amount of transmission capacity for commercial trading. In this paper, Benders decomposition method, based on Optimal Power Flow (OPF), is proposed to partition the static security constrained ATC problem into a base-case master problem and a series of subproblems relevant to various contingencies. The master problem is used to handle the base-case power flow constraints and Benders cut constraint from the corresponding subproblem, and each subproblem is used to generate the static security constraints from the corresponding contingency. The mathematic model is formulated and the two improved solution schemes are presented. Computer testing on the 4-bus system and IEEE 30-bus system shows clearly the effectiveness of the proposed method and solution schemes.
