## Macromodelling as an approach for short-term load forecasting of electric power system objects

In the paper methods of construction of mathematical models intended for the power consumption forecasting are discussed. Alternative method of forecasting of defined object using discrete macromodels which allows to conduct quantative analysis of characteristics of the electric energy consumption in the future using known previous data obtained during the field test is proposed.

## Effectiveness evaluation of discrete macromodelling to forecast power consumption of electric power system component elements

The paper is concerned with a method intended for forecasting electric power consumption using discrete macromodels of daily and annual electric power consumption of defined objects. The method provides the possibility of estimating qualitative characteristics of future electric power consumption based on known prior data.
