Cybersecurity of Grid-Connected PV Systems: Analysis and Impacts on the Australian Grid Stability
(Saudi Digital Library, 2024-07-29) Al Fayi, Abdulrahman; Musleh, Ahmed
The rapid integration of grid-connected photovoltaic (PV) systems, is transforming the energy sector, offering significant advancements towards sustainable energy solutions. By 2022, solar energy has become an important power source, with Australia's capacity reaching approximately 26 gigawatts (GW) and the global capacity extending to around 1070 GW. However, these systems are vulnerable to cybersecurity threats, particularly False Data Injection Attacks (FDIA), which can disrupt their stability and security. Given the importance of PV systems in reducing reliance on fossil fuels and lowering greenhouse gas emissions, understanding and mitigating these vulnerabilities is crucial. To address these challenges, this research focused on analyzing the impacts of FDIA, on PV grid-connected systems using the Australian 14 Generators System model which is a close estimation of the Australian National Electricity Market (NEM). We implemented various attack scenarios to assess their effects on system stability and performance. My contributions included the development and simulation of these scenarios using MATLAB, as well as the analysis of the resulting data to identify the impacts and propose mitigation strategies. Our findings revealed significant fluctuations in voltage, current, and power under different attack scenarios. Specifically, regions like Queensland and South Australia exhibited severe instability, with South Australia experiencing system failures under high attack magnitudes. Conversely, regions such as Victoria were less affected. These results underscore the critical need for robust cybersecurity measures to protect PV grid systems and ensure their reliable integration into the energy grid.
