Efficient Energy Management for the Smart Sustainable City Multifloor Manufacturing Clusters: A Formalization of the Water Supply System Operation Conditions Based on Monitoring Water Consumption Profiles

Abstract

This study is devoted to improving the energy efficiency of urban infrastructure systems (UISs), in particular, the centralized water supply of a city multifloor manufacturing cluster (CMFMC), by developing the principles of effective energy consumption management. The CMFMCs are located in the residential area of a megapolis and include manufacturing and service enterprises, residential and non-residential buildings, and a city logistics node. Demand monitoring and identification of the influence of seasonal and social environmental factors on its fluctuations is considered as a tool for identifying changes in the operating conditions of the water supply system (WSS) for the CMFMC facilities. To identify the typical operating conditions of water supply facilities, an approach is proposed that involves the analysis of daily water consumption profiles (WCPs). The formation of a database, the formation of groups of the same type of daily WCPs, and the construction of typical daily WCPs for typical groups and their description are the main stages of the proposed approach. The database contains a set of classification characteristics that describe the daily water consumption and its unevenness, as well as the shape of the daily WCP. The principal component analysis was applied to determine the dominant components of daily water consumption. A set of morphometric parameters was used to describe the shape of the daily WCPs. The methods of cluster and discriminant analysis were used to identify the influence of seasonality and social factors on water consumption and to form groups of the same type of daily WCPs. The analysis of sets of similar type of daily WCPs for typical days of typical seasons was carried out for a formalized description of the typical operating conditions of water supply facilities. The results of the analysis are the clarification of the equations of the dominant components of daily water consumption, the determination of the average values of the characteristics of daily water consumption, and the construction and description of typical daily WCPs for typical operating conditions of water supply facilities. The research results were obtained on the basis of the data of the monitoring systems for water supply enterprises in Ukraine and Poland in 2021–2022. The obtained results are the basis for planning the water supply process and adjusting the operation modes of WSS pumping stations for the CMFMC, as well as planning power consumption for typical operating conditions, which will contribute to increasing the efficiency of water and electricity use.

Green technologies in smart city multifloor manufacturing clusters: A framework for additive manufacturing management

“…Maintaining a balance of material and energy flows in the CMFMCs is a necessary condition for the implementation of its manufacturing activities in accordance with the sustainable development goals of the megapolis (Ghadimi et al, 2014;Dzhuguryan et al, 2020;Davydenko et al, 2023;Hegab et al, 2023).…”

“…Flows of energy, water and wastewater after its filtration (if necessary) are allocated to the production enterprises of the CMFMCs by infrastructure enterprises of the megapolis, taking into account the existing capacity limitations, which are determined by their current potential. Distribution of allocated infrastructure capacity to the production enterprises is carried out on a contractual basis, taking into account the facilities multi-floor layout in the buildings of the CMFMCs (Mouzon et al, 2007;Modrzyński and Karaszewski, 2022;Davydenko et al, 2023). The production enterprises of the CMFMCs maintain a balance between consumed and allocated energy and water resources to ensure uninterrupted production activities (Dzhuguryan et al, 2020;Davydenko et al, 2023).…”

“…The material and energy flows in the buildings of the CMFMCs depend on the capacity of the available technological equipment and their multi-floor layout, which determines the production logistics of the enterprises (Ghadimi et al, 2014;Dzhuguryan et al, 2020;Davydenko et al, 2023). Therefore, the facilities multi-floor layout problem in the buildings of the CMFMCs is subject to a separate study.…”

“…In addition, the CMFMCs are located in the large city of megalopolis with a long-established infrastructure of the residential area, in the buildings of which family enterprises are organized using existing freight elevators and green ATs (Khorram Niaki and Nonino, 2018;Dzhuguryan et al, 2020;Dudek et al, 2022). It is obvious that the chaotic layout of multi-floor facilities in such buildings of the CMFMCs will lead to the collapse of manufacturing activity due to a violation of the material and energy flows balance (Ghadimi et al, 2014;Dzhuguryan et at., 2020;Davydenko et al, 2023). The possibility of an imbalance of material and energy flows in each production building of the CMFMC is associated with infrastructure capacity limitations, which are defined by the throughput capacity of freight elevators, energy and water resources of infrastructure enterprises of the megapolis (Dzhuguryan et al, 2020;Modrzyński and Karaszewski, 2022;Davydenko et al, 2023).…”
