Transmission losses account for about 5% of total demand. While the introduction of variable renewable energy resources such as PV and wind power generation is expanding toward achieving carbon neutrality by 2050, curbing the national burden has become an issue. Since reduction of transmission losses leads to suppression of the national burden through effective utilization of fuel resources and transmission facilities, it is important to study the overall optimization of the power system that takes transmission losses into account. This paper proposes a supply-demand analysis model that is based on the DC optimal power flow method and is capable of calculating the unit commitment of generators considering transmission losses. The purpose of this study is to report the usefulness of the proposed model by quantitatively evaluating the effect of considering transmission loss costs in the merit order using the proposed model. The proposed model can be utilized in the future supply-demand analysis for offshore multi-terminal DC transmission networks by considering the transmission losses.
