论文摘要
这项工作研究了智能网格中分布式控制方案的潜在脆弱性。为此，我们考虑了PV集成分布网络中的最佳逆变器VAR控制问题。首先，考虑到反应能力优先级，我们提出了集中的优化问题，并通过加速的近端投影方法将问题进一步将问题重新将问题重新制定为分布式框架。逆变器控制器可以通过夹紧反应能力来减少每个用户的PV输出。为了说明由于两跳信息通信模式而导致的研究的分布式控制方案，我们提出了在信息交换过程中注入虚假数据的启发式攻击。然后，我们分析对关键参数更新过程的攻击影响。用八节点测试器进行的案例研究表明，对手可以违反分布式控制方案的约束，而不会通过诸如拟议攻击之类的简单攻击来检测到。
This work studies the potential vulnerability of distributed control schemes in smart grids. To this end, we consider an optimal inverter VAR control problem within a PV-integrated distribution network. First, we formulate the centralized optimization problem considering the reactive power priority and further reformulate the problem into a distributed framework by an accelerated proximal projection method. The inverter controller can curtail the PV output of each user by clamping the reactive power. To illustrate the studied distributed control scheme that may be vulnerable due to the two-hop information communication pattern, we present a heuristic attack injecting false data during the information exchange. Then we analyze the attack impact on the update procedure of critical parameters. A case study with an eight-node test feeder demonstrates that adversaries can violate the constraints of distributed control scheme without being detected through simple attacks such as the proposed attack.
