【摘要】 电力电子设备以及分布式电源(distributed generation, DG)在配电网中的渗透率逐渐提高，现有故障恢复方案未能充分利用智能软开关(soft open point, SOP)的短时过载能力以及DG的爬坡支撑作用，资源利用不充分。提出一种考虑SOP短时过载能力和DG爬坡特性的有源配电网多时段故障恢复方法。首先，介绍SOP的基本原理，构建考虑SOP短时过载能力的数学模型。然后，分析DG爬坡支撑特性，给出DG故障恢复中的数学模型，建立含SOP的有源配电网多时段故障恢复数学模型。并且明确了SOP与DG的动态协同过程，提出多时段故障恢复流程。最后，在IEEE33节点配电系统上开展仿真分析，结果表明所提方法能够显著提升配电网故障恢复的能力，验证了该方法的有效性。更多还原

【Abstract】 With the increasing penetration of power electronic devices and distributed generation(DG) in distribution networks, existing fault recovery schemes fail to fully utilize the short-term overload capability of soft open points(SOPs) and the ramping support of DGs, leading to insufficient resource utilization. To address this issue, this paper proposes a multi-period fault recovery method for active distribution networks, incorporating SOP short-term overload capability and DG ramping capability. First, the operating principle of SOPs is described, and its mathematical model with short-term overload capability is formulated. Then, the post-fault ramping behavior of DGs is analyzed, and a corresponding mathematical model for DG participation in fault recovery is developed. Based on these models, a multi-period fault recovery optimization framework is established, in which the dynamic coordination between SOPs and DGs is explicitly characterized, and a corresponding recovery procedure is developed. Case studies on the IEEE 33-node system verify that the proposed method can significantly enhance fault recovery capability of distribution networks, proving its effectiveness.更多还原
