Elektrik dağıtım ağlarının verimliliğinin modellenmesi

In 2009, power loss occupied approximately fifteen percent of the total generated electricity in Turkey. These losses can be classified into two subgroups, technical and non-technical losses. Technical losses occur mainly because of the electricity system components; (i)transformers, (ii)cables which are being used in transmission and distribution lines, and (iii)measurement systems. Among these components, cables that carry electricity remain as the major factor for the technical power losses. In cables, corona loss and resistive loss are the primary reasons behind the losses during transmission of power. Non-technical losses can be listed as electricity theft, non-payment by customers and errors in record keeping and accounting. Technical losses can be minimized by selecting the right type of material and optimizing the network parameters, which include resistance, size and length of the cables. In this thesis, main motivation is to minimize power generation cost by reducing power loss during transmission while satisfying capacity and balance constraints. Whole analysis is implemented by the GAMS software. All data used for the analysis is taken from TEIAS, Turkish Electricity Transmission Company.
