Switching attacks on smart grid using non‐linear sliding surface

A cyber‐intruder uses the local knowledge of grid in order to develop and apply a coordinated switching sequence to attack and destabilise an otherwise healthy smart grid system. In this study, the attacker utilises the swing equation to discover the stable boundary limit of the target generator and...

Description
Summary:A cyber‐intruder uses the local knowledge of grid in order to develop and apply a coordinated switching sequence to attack and destabilise an otherwise healthy smart grid system. In this study, the attacker utilises the swing equation to discover the stable boundary limit of the target generator and applies non‐linear sliding surface (NLSS) technique to compute switching sequences and perpetrate attacks through gained access over a target circuit breaker for the disruption of normal operation. The targeted generator in the Western Electricity Coordinating Council 3 machine, 9‐bus system, and New England 10‐generator, 39‐bus system are attacked using a line switching event. An NLSS‐based load switching triggered an attack is also executed in a single machine infinite bus system to compare against the linear sliding surface‐based attack performance. The valour of an attack lies in its swift and fast action. Both these aspects are highlights of this work as the application of NLSS reduces chattering and achieves much faster spiralling out to instability.
