   Abstract

   This chapter names and explains the basic concepts in the field of energy saving and improvement of the energy efficiency (ES and IEE), which are the main subject of consideration in this monograph with an emphasis on industrial enterprises. It is shown that not in all cases the amount of savings obtained as a result of the implementation of measures on ES and IEE exceeds the funds invested in them.

   Abstract

   This chapter deals with existing approaches and methods for managing electrical power consumption (EPC) by industrial enterprises. When considering these approaches, the focus is primarily on modeling, rationing, and forecasting. Methods for managing (EPC) by industrial enterprises are analyzed through both direct and indirect methods.

4. Chapter 3. Energy Balances

   Abstract

   In the chapter, the structure, purpose, types, and application areas of energy balances (EB) are discussed, along with the technology of their composition. EBs are classified according to the types of energy, time and stage of development, purpose, stages of the life cycle of energy resources, qualitative characteristics, and the scale of the object. Described are actual, normalized, rational, optimal, and ideal EBs. Examples of EBs of an enterprise and its subdivisions are provided.

5. Chapter 4. Classification of Industrial Enterprises and Technological Equipment

   Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

   Abstract

   In this chapter, a general characterization of industrial enterprises is discussed. According to a typological classification that encompasses the main sectors of industrial production, industrial enterprises are divided into ten basic groups. The classification differentiates between industrial enterprises with continuous and discrete manufacturing cycles, as well as the equipment used in the technological process, which is categorized based on its purpose: universal, specialized, and general purpose.

6. Chapter 5. Changes in Energy Parameters Over Time

   Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

   Abstract

   This chapter is focused on analyzes typical daily load profiles of electrical power consumption (EPC) in industrial enterprises of various profiles, based on multi-year data. The peculiarities of the technological processes at these enterprises are described, and the main patterns of (EPC) by these businesses are determined. In the process of analyzing the dynamics of electrical loads, the main problems in managing (EPC) under conditions of variable demand are identified, and priority directions for solving this issue are determined.

7. Chapter 6. Analysis of Energy Indicators

   Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

   Abstract

   A detailed analysis of the energy indicators of industrial enterprises is necessary due to the complexity of technological processes, which does not allow for a comprehensive analysis of these indicators. In light of this, the monograph provides a detailed description of the methodology for analyzing energy indicators based on decomposition, as proposed by the authors of the monograph. This complex task is resolved in a simpler manner by dividing the analyzed parameters into several subsystems.

8. Chapter 7. Rationing of Electrical Power Consumption

   Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

   Abstract

   The chapter deals with identifying and analyzing factors that affect electrical power consumption (EPC). It offers methodologies for determining normative values of EPC based on multifactor analysis and on the criterion of minimizing production costs. The proposed methods are substantiated based on real calculations for operating enterprises.

9. Chapter 8. Differentiated and Consolidated Specific Norms of Electrical Power Consumption

   Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

   Abstract

   This chapter discusses the composition and classification of electrical power consumption (EPC) standards (individual, group, technological, and general production). An approximate composition of the norms for electricity consumption by industrial enterprises is given. Consolidated and differentiated standards are described, and the relevance of their application is justified. Methods for determining differentiated and consolidated energy consumption standards are proposed.

10. Chapter 9. Forecasting Electrical Power Consumption

    Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov

    Abstract

    In the chapter, the primary requirements and stages for developing models to forecast electrical power consumption (EPC) are proposed. To enhance the accuracy of forecast indicators, prediction models utilizing artificial neural network methodology are developed. The advantages and disadvantages of various estimation methods are analyzed; corresponding algorithms and software products for this purpose are proposed.

11. Chapter 10. Reserves of Energy Saving and Improvement of the Energy Efficiency

    Ikromjon U. Rakhmonov, Vasiliy Ya. Ushakov, Foziljon A. Khoshimov, Numon N. Niyozov, Nurbek N. Kurbonov, Alexey V. Mytnikov
