N2 - The electrical state of the power distribution grid can be estimated based on noisy measurements of a subset of voltages and currents in the grid. The accuracy and cost of such state estimation depends strongly on the selection of measurands. This paper addresses the selection of measurands, i.e. choice of which voltage and current phasors to measure, for the purpose of grid state estimation. The investigation is based on calculation of so-called leverages known from mathematical statistics. Based on the leverages a greedy measurand selection algorithm is prosed. The performance of the algorithm is studied by simulation in a small and a larger example grid.
