A Survey on Cyber-Security in Smart Grid

The smart grid is perceived as a complex cyber-physical ecosystem consisting of a variety of infrastructures. The increasing intricacy and interconnectivity of smart grid elements have rendered security a vital consideration. A significant number of research papers have being conducted to mitigate the cyber-attacks. Nevertheless, the majority of existing security measures concentrates on addressing specific attacks or safeguarding individual components, lacking a comprehensive approach that integrates these solutions to protect the safety of the overall system. In this article, we outline relevant literatures. Initially, we delve into several significant cyber attacks to identify possible threats in the smart grid. Subsequently, we present suitable cyber security countermeasures. Lastly, we propose the research challenges, along with significant research gaps, in order to provide insights into potential future research directions.
