New approach to modeling the nonlinear loads

... modes that were obtained by measurements have shown that harmonic modes are random, and their parameters have probabilistic nature. Due to unpredictability of harmonic modes, nonlinear loads can be modeled using measured parameters. The paper presents methodological approach, algorithms and a computing program for modeling the nonlinear loads using parameters measured in the nodes of their connection to the power supply, and gives examples of modeling the nonlinear loads. © The Authors, published ...

Methods of redundant schemes and software for optimization of heat source structure

... economic problems to design these systems, which, in turn, predetermines the transition to a new level of their methodological support [2]. The paper proposes a mathematical formulation of the problem of optimal development of heat sources and considers a methodological approach to solving it, including effective load distribution between heat sources, and calculation of the optimal heat network configuration, given the minimum environmental impact of heat sources. © The Authors, published by EDP Sciences,...

Significant factors affecting the selection of rational options for power supply in an off-grid zone

....1051/e3sconf/20197702006 The paper presents a short characteristic of an off-grid zone in the eastern regions of the Russian Federation. The main problems of power supply to consumers in this zone are described, and possible options for solving them are provided. A methodological approach and model tools to estimate the efficiency of alternative options of power supply to off-grid consumers are described. The factors affecting the selection of a rational option of power supply in the off-grid zone are classified....

Growth of investments as a condition for increasing energy efficiency of the Irkutsk region's economy

... socio-economic development, is of particular relevance due to its high energy intensity. The purpose of the study is to perform an energy-economic analysis of the Irkutsk region, and to determine the impact of investment on the energy efficiency growth. The methodological approach developed by the authors and used in this research is based on the balance and statistical methods. In course of the research, retrospective fuel and energy balances (FEB) of the Irkutsk region have been developed, and the energy ...

Regression model for heat consumption monitoring and forecasting

... and economically important in our country. In this regard, high-quality monitoring and planning of the development of heat supply systems are a strategic vector of scientific research. This paper is focused on the studies demonstrating how to choose a methodological approach to describe changes in heat consumption in the retrospective. The change in heat consumption is described using multiple regression models. In the first part of the paper, the parameters for the regression model are determined ...
