Reduction of the Net Losses in Distributed Networks

For loss reduction In distributed networks a multiplicity of possibilities exist. The use of cables instead of overhead lines as well as larger diameters of the lines lower the arising losses in distribution networks. Likewise a more even load profile leads to a reduction of losses, so that in the consequence primary energy, costs and CO2-emissions can be saved. Unbalances through asymmetrical loads arise particularly within the low-voltage grids and they are responsible for substantial losses compared with the situation of symmetrical load conditions. In this paper investigations are presented, which show that considerable loss reductions can be obtained by decentralized compensation. For the computation of the losses in urban distribution networks a model is developed. The parameters (standardised load profiles, number and kind of typical consumers, line data etc..) can be varied. Results of model computations are presented.
