Improving operation of medium voltage grid with state estimator and advanced metering system

This paper adopts a state estimator and a meter placement approach to improve the operation of medium voltage distribution grids. In the framework different input specifications are designated. Moreover, three common activities during normal operation are analyzed in detail: voltage regulation, switching consequence assessment, and loss estimation. To evaluate the performance of these activities, several indices are defined. To demonstrate the improvements that the framework may gain over the currently used operation strategy, an extensive case study is performed on a typical European distribution grid.
