A bad data detection approach to EPS state estimation based on fuzzy sets and wavelet analysis

A bad data detection approach to EPS state estimation based on fuzzy sets and wavelet analysis

The paper offers an algorithm for detection of erroneous measurements (bad data) that occur at cyberattacks against systems for data acquisition, processing and transfer and cannot be detected by conventional methods of measurement validation at EPS state estimation. Combined application of wavelet...
