ABSTRACT

This chapter identifies the security challenges of the smart grid and explores the space of attacks in the energy management process; including modules being attacked, attack venue, attack strength, and system knowledge. It describes the attacks against distributed energy transmission and dynamic state estimation as case studies to investigate the risk of those attacks. The chapter examines the defense taxonomy to secure energy management with three orthogonal dimensions: methodology, sources, and domains. It introduces an integrated defensive strategy and en-route filter-based defensive strategy and discusses how to establish a unified theoretical framework to investigate the effectiveness of the synergy of risk analysis, threat detection, and defense reactions and the interactions with attacks using system theory such as control theory and game theory. The chapter provides a literature review of the smart grid and relevant security research efforts. It presents the background of the smart grid and its security challenges.
