Some embodiments provide a system to protect an electric vehicle charging infrastructure. An electric vehicle charging site may receive Alternating Current (“AC”) power from a power grid and provides Direct Current (“DC”) power to electric vehicles. A sensor spoof observer and controller may receive information from at least two AC current sensors, wherein the observer calculates a grid voltage disturbance using a structure based on an AC filter dynamic model. A system stability assurance platform may: (i) monitor current and voltage to detect resonance, (ii) identify impedance associated with a detected resonance, and (iii) apply a result of an analysis of the identified impedance to an adaptive damping control algorithm. A user interface platform may then provide information about a component of the charging infrastructure being cyber-attacked to a distribution system operator via a graphical user interface display.
