This paper proposes a multistage Phasor-aided Bad Data Detection and Identification (PBDDI) method to improve state estimation accuracy. This method defines a special kind of innovation— the difference between estimated SCADA measurements (calculated from valid PMU state estimates) and raw SCADA measurements, then proposed statistical residual test is used in a cooperative effort for identifying bad...
This paper presents a solution for the optimal placement of branch PMUs (PMUs that measure a single set of three-phase voltage and current phasors) considering specific measurement redundancy requirements for the observability of buses. The classical bus observability condition in optimal PMU placement assumes the measurement of currents of all lines connected to the PMU bus, making most developed...
