Abstract :
Nowadays distribution system operators are equipped with many real time operation data from SCADA, intelligent electronics devices (IED), automatic meter reading (AMR) and advanced metering infrastructure (AMI) systems. Customer and transformer loading data obtained from AMI system at different time intervals give an opportunity to develop a distribution state estimation (DSE) algorithm. DSE is enabler of many smart distribution applications. In this paper, a DSE based quasi real time search for potential irregularity of electricity usage is presented. The proposed approach can be used to reduce non-technical loss in the distribution network.
