MicroGrids (MGs) are foreseen as a building block of the smart grid. They allow for the integration of distributed energy resources and storage within the conventional grid. This is partly possible through deployment of Information and Communication Technologies (ICTs) within these structures. Therefore cyber security is a major concern for MGs. This paper investigates cyber-physical security aspects of the MG, including vulnerabilities and threat landscape. A cyber-physical security risk assessment is presented for evaluating impacts of exploiting existing vulnerabilities by potential threats on MG operations.
