Resilient Control Strategy for Seaport Microgrid Against False Data Injection Attacks Based on Interactive System

Abstract

One of the most popular control strategies for seaport microgrids (SMGs) is distributed control because it efficiently combines the benefits of centralized control with distributed control, lowers communication and calculation complexity, and enhances dependability and scalability of the system. The stability of the system and the safety of the inverter are at risk, though, because there is no central controller for monitoring the activities of the generator set. As a result, under the influence of potential network attacks, the control decisions between distributed generations (DGs) will be directly destroyed, and the power sharing between DGs will be hampered. To address the secondary control problem of the microgrid under false data injection (FDI) attacks, inspired by the concept of Digital Twins, this study proposes a virtual network defined by cloud network technology or software and linked to the microgrid's distributed cooperative control algorithm, to achieve frequency (voltage) synchronization and power sharing of SMGs.
