摘要/Abstract

摘要： 在主动配电网信息物理系统中，信息系统与物理网架之间存在强耦合关系。在电网复杂的信息物理交互作用下，信息系统的异常或故障会直接影响并降低电力系统的运行水平，甚至引发严重的连锁故障。且相对于传统电力系统，电网信息物理系统的风险致因因素更多，交互机理更复杂，监测识别更困难。电网信息物理系统的安全风险问题已成为当前亟待解决的基础问题之一。以主动配电网为研究对象，对信息侧架构与信息物理交互机理进行分析，建立了信息攻击下的风险传递模型，揭示了故障在配电网信息物理系统中的演化机理。最后，在DIgSILENT中搭建仿真算例进行实例分析，验证了所提出模型的正确性，并对未来配电网如何抵御信息侧风险，加强安全风险防护水平提出了建议。

Abstract: In the active distribution network cyber-physical system exists a strong coupling relationship between the cyber system and the physical grid. Under the complex cyber-physical interaction, the cyber system anomalies or failures will directly affect and reduce the operation level of the power grids, and even cause serious cascading failures. Compared to the traditional power system, the risk incentives of the power cyber-physical system are more diversified, the interaction mechanisms are more complicated, and the identification are more difficult. The power system cyber-physical security risk has become one of the fundamental issues in the power system operation. By taking the active distribution network as an example, we establish a risk transfer model for active distribution networks under cyber-attacks to reveal the evolution mechanism of failures in the distribution network cyber-physical system. Finally, a simulation case study is carried out with DIgSILENT to verify the correctness of the proposed model, and some suggestions are proposed on how to prevent cyber-side risks in the future distribution network and improve the level of security risk protection.

Key words: active distribution network, cyber physical system, feeder control error, risk evolution, cyber attack
