For economic reasons, consumer appliances and communication channels do not have high cyber-security. So, due to the consumer section’s vulnerability and the communication channel, the consumer section is a potential candidate for some cyber attackers. In this paper, the destructive impact of the false data injection attacks (FDIAs) on the demand response real-time pricing is investigated. Attacker manipulating the real-time price (RTP) signal in the smart meter causes the change in the consumer’s load profile that affects network operation. This condition helps the attacker maximize the power losses in the distribution networks subject to the available attacker budget and security levels (SLs) of smart meters. A defense strategy based on the distribution network reconfiguration is proposed against FDIAs to mitigate the harmful effects of launched cyber attacks. Also, a bi-level optimization is used to model FDIA and defense strategy. At the upper level, smart meters’ optimal location is modeled to launch the FDIA constrained by the attacker’s total budget. Also, at the lower level, the network reconfiguration is modeled to find the switch’s optimal state to defend against attack. Simulation carried out on the modified IEEE 94-bus system to evaluate the proposed defense strategy efficiency.

出于经济原因，消费电器和通信渠道没有高度的网络安全性。因此，由于消费者部分的脆弱性和通信渠道，消费者部分是一些网络攻击者的潜在候选者。在本文中，研究了虚假数据注入攻击（FDIA）对需求响应实时定价的破坏性影响。攻击者操纵智能电表中的实时价格 (RTP) 信号会导致消费者负载曲线发生变化，从而影响网络运行。这种情况有助于攻击者根据可用的攻击者预算和智能电表的安全级别 (SL) 将配电网络中的电力损失最大化。针对 FDIA 提出了一种基于配电网络重构的防御策略，以减轻发起的网络攻击的有害影响。此外，使用双层优化对 FDIA 和防御策略进行建模。在上层，智能电表的最佳位置被建模以启动受攻击者总预算约束的 FDIA。此外，在较低级别，对网络重新配置进行建模以找到交换机的最佳状态以防御攻击。在改进的 IEEE 94 总线系统上进行仿真以评估所提出的防御策略效率。对网络重新配置进行建模以找到交换机的最佳状态以防御攻击。在改进的 IEEE 94 总线系统上进行仿真以评估所提出的防御策略效率。对网络重新配置进行建模以找到交换机的最佳状态以防御攻击。在改进的 IEEE 94 总线系统上进行仿真以评估所提出的防御策略效率。
