Abstract: Switch status identification (SSI) in distribution networks is a challenging task due to the limited measurement resources and therefore the inevitable need is to use pseudo-measurements that are often inaccurate. In this Webinar, I will introduce a new method which integrates harmonic synchrophasors into the SSI problem in order to enhance SSI accuracy in distribution networks. In this method, switch status identification is done jointly based on both fundamental synchrophasor measurements and harmonic synchrophasor measurements. This is done by formulating and then solving a mixed-integer linear programming (MILP) problem. Furthermore, I will provide an analysis to capture the number of and the location of harmonic sources and sensors that are needed to ensure full observability.
