The main directions of the energy strategy of railway transport are to improve the management structure of the railway energy complex, reduce the cost of electric energy and reduce the cost of its acquisition. The initial information for planning optimal operating modes in the management of the energy complex is provided by the forecast of electricity consumption. According to the rules of functioning of retail markets, consumers are required to accurately plan the volume of electricity consumption. If the power consumption deviates by more than 5% of the planned volume, the company incurs additional costs. To make an accurate forecast, it is necessary to analyze the source data – the archive of electricity consumption. At the initial stage of data analysis, the problem of omissions is revealed. If there are gaps in the data, the process of forecasting electricity consumption can be difficult, and sometimes impossible. The most rational solution is to fill in the gaps using modern methods of information processing. This will allow you to clearly present the data structure, calculate the necessary values and interpret the results of the analysis.
