Abstract

Determining the energy consumption level is one of the stages of energy efficiency monitoring facilities. The aim of the article is to adapt the energy baseline to the operating conditions of the facility in accordance with the ISO 50000 Standards requirements. The methodology for determining the energy baseline was proposed to achieve the goal. The three-stage procedure for forming a set of relevant variables of the energy baseline, which allows taking into account the significance of variables, the possibility of their measurement, controllability and control, and the procedure for constructing a multifactorial model of the optimal structure for determining the energy baseline are the main scientific results. This methodology was applied to a boiler house of a district heating system. Relevant variables were formed using a three-stage selection of factors that influence the gas consumption efficiency of the boiler house. Combinatorial algorithm of the group method of data handling was used for gas consumption simulation. The search for models of optimal complexity was performed in six classes of basic functions. The selection of better structures of the mathematical model was realized based on the criteria for its appropriateness (regularity, unbiasedness criterion, Schwartz, determination coefficient) and accuracy of the forecast using the morphological criterion. As a result, a multifactor mathematical model of optimal structure was obtained. The percent forecasting error did not exceed 1%. The significance of the results lies in the fact that the proposed methodology can be applied to any facility.

Highlights

  • According to the International Energy Agency (IEA), in the modern energy strategies of the EU [2] and Directive (EU) countries, which are consumers of a considerable amount of energy resources, priority is given to the problem of energy efficiency [1]

  • The proposed methodology was used for the construction of an energy baseline (EnB) for the boiler house of the district heating systems (DHSs)

  • Electric power, and water are consumed for the heat production by the boiler house of the DHS

Summary

Introduction

According to the International Energy Agency (IEA), in the modern energy strategies of the EU countries, which are consumers of a considerable amount of energy resources, priority is given to the problem of energy efficiency [1]. Energy Efficiency Directive 2012/27/EU [2] and Directive (EU) 2018/2002 [3] requires the efficient use of energy in all areas. Directive (EU) 2018/2002 [3] sets a target to improve energy performance by at least 32.5% by 2030. This requires a reduction in primary energy consumption by 26% and a reduction in final energy consumption by 20% compared to 2005 levels [3]. Regular evaluation of progress towards energy efficiency targets is provided by Regulation 2018/1999 of the European Parliament and of the Council [4]. The requirement of energy performance improvement is mandatory for district heating systems (DHSs) and heat energy producers
