摘要

为应对输电系统信息物理复合故障，提出了一种计及通信系统失效的信息物理协同恢复策略。首先，基于发电机、电力线路与负荷的故障特性，综合考虑了系统频率、节点电压、线路容量等安全约束，构建了物理系统的恢复模型。然后，提出了一种基于通信网络拓扑的信息系统恢复策略。接着，考虑信息系统故障给发电机出力调节、电力线路投运以及负荷恢复可能造成的延时，建立了物理系统恢复与信息系统恢复的交互模型。经过对潮流线性化处理，上述3个模型被整合为一个混合整数二阶锥规划模型。最后，以IEEE 30节点标准电力系统为基础构建了输电信息物理系统算例，来说明所提方法的可行性与有效性。算例结果表明，所提出的协同恢复策略能有效避免信息物理恢复操作不协调引起的二次停电，从而加快负荷恢复、降低停电损失。

Abstract

To cope with cyber-physical coupling failures of the power transmission system

a cyber-physical collaborative restoration strategy for a power transmission system subject to communication failures is proposed. First

a restoration model of the physical system is established based on the restoration characteristics of generators

power lines and loads

and with the system security constraints including system frequency

bus voltage

and branch capacity comprehensively considered. Next

a cyber restoration model is proposed based on the network topology of the cyber system. Then

the interactions between physical and cyber systems are modeled by utilizing the operation time delays of power output adjusting of generators

power line restoration

and load pickup due to communication failures. The above three models can be integrated into a mixed-integer second order cone programming (MISOCP) model through the linearization of the power flow. Finally

the feasibility and effectiveness of the proposed method are demonstrated by a sample cyber-physical transmission system modified from the IEEE 30-bus power system. Case Study results indicate that the proposed collaborative restoration strategy manifests its superiority in avoiding additional outages

accelerating system recovery and reducing outage losses.
