摘要
在独立交直流微电网中,叠加在互联统一控制上的虚假数据会导致微电网在能量层出现较大偏差。首先介绍交直流混合微电网的分布式控制架构;然后从难以被恶意篡改的本地硬接线量测出发,提出一种基于数据驱动的互联统一控制虚假数据检测策略。算法通过对虚假数据的异常行为进行离线学习,利用实时数据进行在线判断,进而对虚假数据实现快速检测并发出及时预警。在分辨出扰动的来源后,进一步使用隐蔽链路或一阶保持的方式降低虚假数据的不良影响。最后,通过算例仿真验证了所提策略的正确性。
In isolated AC/DC hybrid microgrid,the false data added on the unified control will lead to a large deviation in the energy layer.Aimed at this problem,a distributed control architecture of AC/DC hybrid microgrid is introduced.Then,based on the analog measurement which is difficult to be tampered with maliciously,a data-driven false data de⁃tection strategy for unified control is proposed.This algorithm performs offline learning to the abnormal behavior of false data and uses real-time data to make online judgment,thus realizing a fast detection of false data and sending out a timely warning.After the identification of the disturbance source,the hidden link or first-order holding method is fur⁃ther used to reduce the adverse effects of false data.Finally,the proposed strategy is verified by simulations.
