Power transmission and distribution losses - A model based on available empirical data and future trends for all countries globally

This article aims at the creation of a holistic and analytic function for describing the transmission and distribution (T&D) grid power loss for all countries globally based on economical, geographical, political and technical available data. The created function is the very first of its kind, it is statistically well validated, and several examples are discussed. The function based on empirical data describes the dependence of the T&D grid power loss level on widely available metrics, such as GDP per capita, corruption perception index, area of the country, temperature, grid organization parameter and level of urbanization. The same function can also be used by modellers to anticipate the development of the T&D grid power loss in the years and decades to come. The suggested methodology could be easily reproduced and tuned to precise environmental conditions, what can be helpful for research in countries without available data.
