Design and test of a real time monitoring system based on a distribution system state estimation

The development of the smart grid requires new monitoring systems feasible to support automation functionalities as control of DER. As the key element in the monitoring system, the real time distribution system state estimation (DSSE) integrated with bad data processor is presented in this work. The developed DSSE is suitable for the real time application because it has the benefits of more computational efficiency, numerical stability and robustness against the measurements with large error. The DSSE is localized within a automation platform, from which the requirements from the output and the specifications of the input are derived. The performance of the real time DSSE is analyzed and discussed by means of simulations performed in a 16 bus distribution network.
