Mapping the size of Mälarenergi power grid losses (English)
Abstract [en]

Energy losses are an essential part of a power grid company’s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area. A customerthat is connected to the mid voltage network should therefore not have to pay forlosses in the low voltage grid.Mälarenergi elnät AB demand a deeper investigation to see if their reported net lossesfor Energimarknadsinspektionen, EI is reasonably accurate or completely misleading.Therefore, this thesis was performed.Today advanced software is used which retrieve measurements from the power gridaround cities. This type of software is monitoring networks in order to detectpossible failures and then fix those errors when necessary. These measurements areused in the thesis to identify the size of the losses in the network. The network isdivided into smaller areas with each area analysed separately. When all areas haveundergone deeper analysis, the results are compared and a final result will beobtained at the end.According to Energimarknadsinspektionen, Mälarenergi elnät energy losses are 2,96%. Losses according to the analysis in this thesis amounts to 3,11 %.
