Micro-grids (MG) enable autonomous operation of remote or islanded power networks such as critical infrastructure assets, but also the integration of Distributed Energy Resources (DER) into power distribution networks coupled to a transmission system, enhancing robustness of and reducing strain on the power network. Micro-grid control technology relies heavily on networked or distributed control techniques which are exposed to cyber-security threats than conventional power networks. Consequences of security violations could manifest as loss of electrical power to critical loads or dangerous operating states; given the severity of the risks every effort should be taken to reduce exposure to vulnerabilities. This chapter reviews common MG architectures and selected system elements feeding into a structured high-level security analysis based on the Systems Theoretic Process Analysis for Security (STPA-Sec) framework to generate causal scenarios for security violations in MGs and, accordingly, to identify the priority areas for future security research in the MG domain.
