As the distribution grids are an important part of the electrical system, their components need to be known in order to achieve optimal control of energy transfer. The present paper considers one component of the distribution grid namely the power line, aerial or cable, its model parameters leading to pseudo measurement uncertainties that can propagate through the entire grid when, for example, state estimation algorithms are applied. The paper discusses the case of short lines in order to decide whether it is important to have a better knowledge on the power lines parameters in estimating the losses of the electrical power system and also for various control strategies in active distribution grids. The validation of estimated parameters is made considering different load conditions for the aerial distribution line.
