基于直接法的地区电网合环潮流计算方法

Direct coupling power flow method of regional power grid

利用地区电网的结构特点和运行方式,提出了一种基于BCBIM和BIBVM方法的地区电网合环潮流计算策略。对单环网及多开关分布线路电网分别采用传统前推回代合环潮流计算和基于BCBIM和BIBVM直接法的合环潮流计算结果进行对比,对比结果显示所提出的合环潮流计算方法与传统前推回代法具有相同的准确度,并具有算法简单、计算速度快、占用计算内存少等优点。

Based on the structural characteristics and operation mode of the distribution network, a calculation strategy of distribution network and ring flow based on BCBIM and BIBVM method was proposed. The single-loop network and multi-switch distributed power grid were respectively compared with the traditional pre-push-integrated loop power flow calculation and the BCBIM and BIBVM direct method based on combined loop power flow calculation results. The comparison results showed the proposed method of the combined loop power flow. It had the same accuracy as the traditional pre-pushback method, and had the advantages of simple algorithm, fast calculation speed and less computational memory.
