Microgrid Control Analysis Considering the Impact of Cyber-Attacks
摘要
Power grids may experience blackouts and cascade failures as a result of cyber-attacks. To ensure the secure operation of modern power system, it is crucial to understand the forms, effects, and solutions of cyber-attacks. A new type of digital technology called a “cyber-physical system” (CPS) is gaining popularity in the academic, governmental, and business worlds. It has a wide range of uses in fields including agriculture, energy, and medicine. The conventional power systems, which have physical apparatus at their core additional elements, are incorporated into information and communication technology as it develops cyber-physical power system (CPPS). A physical system that is closely connected with a cyber system makes up the CPPS. The research herein aims at the frequency control action of a microgrid comprising of hydro source, wind turbine generator (WTG), solar photovoltaic (SPV), biogas turbine generator (BGTG), fuel cell (FC), diesel engine generator (DEG), and battery energy storage system (BESS). The frequency control action for the considered microgrid is carried out by considering a classical proportional–integral–derivative (PID) controller and proportional–integral (1 + proportional–derivative) controller. Three types of cyber-attacks such as denial-of-service (DoS) attack, distributed denial-of-service (DDoS) attack, and false data injection (FDI) attack are reviewed in this paper, and their impacts are shown on the proposed microgrid control using MATLAB Simulink.
