摘要

随着通信网络与电力系统耦合程度的提升，配电网由极端自然灾害导致的故障模式逐渐向信息物理复合故障转变，给全局运行安全带来了极大风险。此外，鲜有研究考虑在配电网中通过协同规划电容器组（CB）和智能软开关（SOP）来降低系统在负荷恢复过程的失负荷成本。针对以上不足，提出一种信息物理耦合环境中面向韧性全过程提升的配电网无功规划方法。在灾前配置CB和SOP，以降低系统直接和间接故障的规模；在灾中、灾后依据通信可靠性理论分析设备受控状态，结合系统通信性能的调节对电力设备进行调控，从而降低系统在韧性全过程的失负荷成本。考虑CB和SOP等设备的响应能力差异，所提策略基于“防御-攻击-多校正”思想被建模为一个分层防御者-攻击者-防御者(DAD)模型。算例仿真结果表明，所提规划策略可以在计及信息物理耦合特性的同时，在无功功率补偿层面提升系统的灾害防御能力。

Abstract

With the increase of coupling degree between the communication network and the power system

the fault modes of the distribution network caused by extreme natural disasters are gradually shifting towards cyber-physical composite faults

which brings great risks to the overall operation safety. In addition

few studies consider reducing the load loss cost of the system during the load restoration process by jointly planning capacitor bank (CB) and smart soft open point (SOP) in the distribution network. To address the above-mentioned deficiencies

a reactive power planning method of the distribution network for whole-process resilience enhancement in cyber-physical coupling environment is proposed. Before the disaster

CB and SOP are configured to reduce the scale of direct and indirect faults of the system. During and after the disaster

the controlled states of equipment are analyzed based on the communication reliability theory

and the power equipment is regulated by combining the adjustment of the system communication performance

thereby reducing the load loss cost of the system throughout the resilience process. Considering the differences in the response capabilities of equipment such as CB and SOP

the proposed strategy is modeled as a hierarchical defender-attacker-defender (DAD) model based on the “defense-attack-multi-correction” concept. The results of case simulations show that the proposed planning strategy can enhance the ability of disaster prevention of the system at the reactive power compensation level while taking into account the cyber-physical coupling characteristics.
