Abstract: Unique systems, methods, techniques and apparatuses of a substation phasor data concentrator (ssPDC) is disclosed herein. One exemplary embodiment is a method for operating an electrical substation including a merging unit (MU), a phasor measurement unit (PMU), and a substation phasor data concentrator (ssPDC). The method includes receiving, with the MU and the PMU, input information corresponding to a set of electrical characteristics of the electrical substation; measuring, with the MU, the input information; measuring, with the PMU, the input information; a and estimating, with the ssPDC, electrical characteristics of the electrical substation using the received false measurement and the one of the MU measurement and the PMU measurement, determining in substantially real time the false measurement does not correspond to the set of electrical characteristics using the estimated electric characteristics, and replacing the false measurement with the received the one of the MU measurement and the PMU measurement.

Abstract: An example method for detecting and mitigating attacks on electric power substations comprises detecting a command to open or close a circuit breaker in the electric power substation. A modified extended substation model for the electric power substation is generated, based on the detected command and based on measurements in substation, where the modified extended substation model is a power flow model for the substation and for one or more directly connected neighboring substations. A power flow analysis is performed, using the modified extended substation model, to generate a predicted voltage for each of a plurality of nodes in the substation and in the one or more directly connected neighboring substations. Each predicted voltage is compared to a corresponding allowable voltage range, and execution of the command is blocked in response to determining that one or more of the voltages is outside the corresponding allowable voltage range.
