In a response to economic growth, electric power utilities installed many electric power facilities to meet power demand. However, these facilities have aged and should be replaced in the near future. Moreover, the demand is said to constantly increase. Therefore, it is necessary to partially upgrade facilities. In this paper, we upgrade transformers with one of the financial engineering techniques...
The Life Cycle Cost (LCC) of power grid assets is a model that was born in China out of necessity because of the liberalization of the energy market. This theory is applied in power system planning to control long-term cost and short-term investment. We proposed a transmission network cost calculation model based on LCC to compare and select the schemes of smart grid planning which considers the effects...
This paper describes a practical technique to quantify transmission asset exposure to unexpected events so that planning engineers can identify and justify cost-effective mitigation measures. The analysis framework uses insurance risk analysis and highlights the need to understand multiple asset outage consequences in the power system. With these inputs annualised outage costs can be estimated and...
Based on different grid development periods, this paper proposes a new method on how to select main electrical connection in different development periods. The annual investment cost function and minimal cut-set reliability model is combined in the proposed method. In different 110kV and 220kV grid development periods, the main electrical connection model based on much survey is helpful for grid planners...
Societies become more and more demanding regarding the future distribution networks role and functionalities. They will have to be accessible to whole actors and in particularly to renewable energies. They must be economic managing for the best the energy efficiency of the system and the energy politics (competition, deregulation). Finally, they must be reliable in order to satisfy the societal expectations...
A method of load fusion is proposed to achieve the subregional and phased planning of best connection modes in 10 kV distribution system based on model design. The best connection mode of the medium-sized region is obtained before considering small corners, and then the load of these corners is fused into the main region by using the model presented in this paper; finally the best connection of the...
This paper presents a study of a distribution network of the large city in a former republic of the Soviet Union. The current situation is analyzed and a new network concept is developed. The major part of the current electrical network has been built in the 1960th and 70th using old Russian technology. The economy develops strongly in the last years, and it can be estimated that the total consumption...
