摘要针对交直流系统因大量不确定性能源接入带来的潮流不确定性问题,建立一种适用于交直流系统的仿射潮流算法,能为系统提供保守性较小的仿射数估计结果,并实现不确定注入功率对系统状态量影响的量化分析。该文首先对三角函数进行仿射运算的推导,而后在仿射原理下建立含电压源换流器的交直流系统不确定潮流求解模型。模型将电压源换流器(VSC)节点分别进行交流节点、直流节点的类型等效,与纯交流、纯直流潮流模型实现求解对应。进而,结合P-Q分解法实现了交直流仿射潮流的快速求解。通过对比多种潮流方法的求解结果并行不确定注入功率对交直流系统状态变量的影响分析,验证了该文算法的有效性和快速性。

Abstract：In this paper, an affine arithmetic based AC/DC system power flow algorithm is proposed to provide a conservative estimation result when the injection power of the system is uncertain. The impacts of each uncertain variable on the system state variables can also be calculated. Firstly, the affine calculation method of the trigonometric function was proposed. And then the uncertain power flow model of the AC/DC system with voltage source converter (VSC) based on affine arithmetic was established. The VSC nodes were equivalent to different types of AC nodes and DC nodes respectively to correspond the solutions of AC and DC power flow models. Furthermore, the fast-decoupled method was used to solve the sequential AC/DC affine power flow. Finally, the effectiveness and rapidity of the proposed algorithm were verified by case studies. And the impacts of the uncertain variables on the system state variables of AC/DC systems were also be given.

Key words： Uncertainty analysis affine power flow calculation voltage source converter AC/DC system
