An Algorithm for Dynamic State Estimation and Bad Data Analysis Using a Square Root Filtering Technique

Abstract

In the last few years we have been faced with an increasing complexity and inteidcpcndcncc of electric Ixlwer systems ancl as a result Uieir security assessnient and control became increasirigly inipoitant. In rcal time power system monitoring, tlie supervisory control and data acquisition system (SCAUA) arc rcspnsiblc lor gathering cyclically all of the analog measurements and breaker psilions from Uie electrical network undcr surveiliancc.
