This article presents a detection technique for data manipulation attacks in distribution systems using transient information present in the measurements. This technique is based on the fact that any legitimate changes in the system will have a transient response which can be measured by the monitoring system. An algorithm is developed for obtaining the transient solution for three-phase distribution networks. A backward–forward sweep technique is developed for the proposed radial electromagnetic transient program (EMTP) which exploits the radial structure of distribution network. An inclusive transient model compatible with the proposed three-phase radial EMTP for three-phase synchronous generators is also developed. The proposed radial EMTP has been benchmarked with conventional EMTP with 5-bus and 22-bus radial distribution systems and with the same test systems, the proposed detection functionality is evaluated. It is shown that the transient solution provided by radial EMTP are in agreement with the results of conventional EMTP. It is also demonstrated that the deviations between the measured values and the solution of the radial EMTP increase significantly during the transient period when a data manipulation attack is carried out.
