Resumo

The performance of control actions on a power system depends on a good monitoring of the grid, which can be provided by the State Estimator (SE). SE is an algorithm that provides a reliable estimation of voltages on all system buses. As it was originally developed for transmission systems, the SE must be rethought in order to suit the specific properties of distribution systems (DS). In this paper, an approach using branch currents as state variables was considered, and a solution to address weakly meshed DS was proposed. IEEE test feeders were used to evaluate the algorithm performance. The chosen methodology was able to estimate the DS state with adequate precision for the different cases considered. (AU)
