A survey of research on smart grid security

Abstract

Smart grid is the goal of China's power grid development, and the security problems can not be ignored during this period. In this paper, we focuse on security risks both in computer network and industrial control network while moving to smart grid. We compared various research works related to these area, and emphasized the importance of SCADA system security. We summarized main attacks on SCADA system and analyzed different approaches to mitigate these threats. We highlighted some achievements of research in SCADA system security, also discussed some shortages of these research. Finally, we discussed the role of testbed in smart grid security research, and compared different testbeds in types and scales, approved their prominent effect in industrial control system security research. © Springer-Verlag Berlin Heidelberg 2012.
