摘要

低压柔性互联装置可以在线路故障情况下对失电负荷进行转供，从而提高配电系统的供电可靠性。针对低压配电台区柔性互联装置接入情况下的可靠性评估和选址定容规划问题，该文提出了一种基于供电可靠性显式计算的低压配电台区柔性互联装置规划方法。首先，提出了基于虚拟潮流的低压柔性互联台区的失电种类划分原则，对线路N−1故障集进行了分类。其次，以用户为最小转供单位，分析了不同失电种类的台区间转供特征，提出了低压柔性互联接入情况下的配电网供电可靠性指标及其显式计算方法，并以失电损失成本和柔性互联装置安装成本为目标函数建立了低压柔性互联装置接入方案的规划模型。最后，通过在IEEE RBTS BUS6 F4配电网算例中求解本文模型，验证了所提规划方法的有效性。

Abstract

Low-voltage flexible interconnection devices can transfer the lost loads in case of line failure and thus improve the power supply reliability of the distribution system. To address the issues of the reliability assessment and location/capacity planning in the case of flexible interconnection device access in low-voltage distribution station areas

this paper proposes a planning method for flexible interconnection devices in low-voltage distribution station areas based on explicit calculation of power supply reliability. Firstly

the principle of dividing the lost power types of low-voltage flexible interconnected station areas based on virtual currents is proposed

and the set of line N−1 faults is categorized. Secondly

the distribution network power supply reliability index and its explicit calculation method in the case of low-voltage flexible interconnection access are proposed with the user as the smallest transfer unit

and the planning model of the low-voltage flexible interconnection device access scheme is established by using power loss costs and installation costs of flexible interconnection devices as the objective function. Finally

the model is solved and the validity of the proposed planning method is verified in the IEEE RBTS BUS6 F4 distribution network case.
