The smart grid cyber-physical system has digital technologies coexisting with legacy power system devices, and its distribution network has been equipped with intelligent electronic devices and advanced metering infrastructure to enhance energy efﬁciency, support increased penetration levels of distributed energy resources (DERs), and enable command and control functionalities down to the customer level. This leads to a potentially larger attack surface and an increased susceptibility to potential cyber-physical attacks.
The infrastructure of DERs was originally designed with the primary intention of harnessing the potential of renewable energy. For such a setting, security at the device, network, or application levels of DERs was of little to no concern. The growing penetration levels of DERs has increased the overall attack surface of critical infrastructure such as smart grids. The lack of in-place security controls has led to many successful cyber-physical attacks over the last five years (REF1).
