AbstractThe successful implementation of smart metering in the European Union (hereinafter – EU) depends on criteria that are mostly determined by the Member States themselves. These criteria cover the regulatory framework and legislation necessary for the establishment and functioning of the smart metering system, the fulfilment of technical and commercial conditions, as well as the security of data collection, archiving and use. The introduction of the smart metering in different Member States has started at different times. In Latvia, its reference point was 2004, when the goal was set to maximise the use of telemetry in the natural gas metering. Currently, in the Latvian natural gas distribution system about 85 % of all consumption data are automatically processed.One of the most important components of the smart natural gas metering is natural gas commercial metering devices (hereinafter – smart meters). They differ in both the principle and type of operation. Depending on the technology used, the metering range changes, and thus the accuracy of the measurements.The article addresses some issues of further successful implementation of smart metering in the Latvian natural gas sector, as well as the measurement accuracy for smart natural gas meters.

This paper is the first country-specific analysis of the market-driven Smart Metering innovation system, covering technologies, actors, and policies. It provides new insights on the key enablers and barriers in the rollout of electricity Smart Meters (SMs) without binding regulatory mandate. The presented research is based on the Technology Innovation System (TIS) analysis for Poland, where an obligation scheme for the rolling out of SMs has been introduced very recently. Still, the number of SMs installed places the country in the top 10 Member States of the European Union. The implementation of SMs is progressing in a complex, multi-actor innovation system, shaped by the leading role of Distribution System Operators (DSOs). The article analyses the key elements of the SM innovation system (technologies and infrastructures, actors and networks, institutions and policies) and characterizes their interaction based on desk research and a critical assessment of regulations, statistics, and literature. The major enablers of the rollout are DSOs expectations of benefits, which have been instigated by the market regulator’s benevolence in tariffs approval. On the other hand, the major barriers are delayed and incomplete public policy instruments. Results of the study can inform the development of other market-driven SM deployments around the world.

The paper describes a new method for numerical monitoring of discrepancies in natural gas supply to consumers, who receive gas from gas distribution loops. This method serves to resolve the vital problem of commercial natural gas accounting under the conditions of deficient field measurements of gas supply volumes. Numerical monitoring makes it possible to obtain computational estimates of actual gas deliveries over given time spans and to estimate their difference from corresponding values reported by gas consumers. Such estimation is performed using a computational fluid dynamics simulator of gas flows in the gas distribution system of interest. Numerical monitoring of the discrepancy is based on a statement and numerical solution of identification problem of a physically proved gas dynamics mode of natural gas transmission through specified gas distribution networks. The identified mode parameters should have a minimum discrepancy with field measurements of gas transport at specified reference points of the simulated pipeline network.

Developing data-driven models for bursts detection is currently a demanding challenge for efficient and sustainable management of water supply systems. The main limit in the progress of these models lies in the large amount of accurate data required. The aim is to present a methodology for the generation of reliable data, which are fundamental to train anomaly detection models and set alarms. Thus, the results of the proposed methodology is to provide suitable water consumption data. The presented procedure consists of stochastic modelling of water request and hydraulic pipes bursts simulation to yield suitable synthetic time series of flow rates, for instance, inlet flows of district metered areas and small water supply systems. The water request is obtained through the superimposition of different components, such as the daily, the weekly, and the yearly trends jointly with a random normal distributed component based on the consumption mean and variance, and the number of users aggregation. The resulting request is implemented into the hydraulic model of the distribution system, also embedding background leaks and bursts using a pressure-driven approach with both concentrated and distributed demand schemes. This work seeks to close the gap in the field of synthetic generation of drinking water consumption data, by establishing a proper dedicated methodology that aims to support future water smart grids.

Background/Objectives: Security features are an essential part of recent smart metering systems. Smart meters are considered an important facility that must be protected by applying the latest security technologies.Methods/Statistical analysis: Security context determines the rules for applying/verifying security. DLMS/COSEM have Security suite to set of cryptographic algorithms. This is based on symmetric key based cryptographic communication. The high level security requires public key based cryptographic communication and digital signature.The security specification references the key scheme of DLMS-COSEM, which is based on a single set of unique symmetric keys per meter.Findings: we have studied a sequence for distributing security keys required by DLMS / COSEM.Our smart metering key distribution system can provide a security key management system such as key generation / distribution between AMI components. This is a PKI-based authentication using public key method (ECC), and a DLMS standard key distribution method after generating a session key using a public key. This system can also provide a key management scheme between DLMS clients not defined in the DLMS standard.Improvements/Applications: we analyze security requirements of DLMS/COSEM for secure smart metering and design key distribution/management method.

Introduction. A promising direction in the development of gas supply systems, which is widely used in the developed countries of the world, is the use of an alternative energy source — biomethane. The effective use of biomethane requires the development of scientific provisions and recommendations for the use of biomethane gas supply systems, taking into account technical and economic factors. Therefore, it is urgent to develop an economic and mathematical model for choosing a gasification method and determining the area of rational use of gas supply systems with biomethane. Materials and methods. To develop an economic and mathematical model for choosing a method for gasification of settlements, methods of mathematical modeling and parametric optimization were used. The implementation of the economic and mathematical model was carried out in the Mathcad software package. Mathematical and graphic processing of the results obtained was carried out. Results. An economic and mathematical model was developed for determining the rational area of application of biome­thane for gas supply to settlements. The model is based on the technical and economic calculation of the reduced costs for gas supply systems with network natural gas and biomethane. Using the developed model, the technical parameters of the biomethane gas supply system were determined: the critical length of the gas pipeline branch, the radius of the biomethane plant, the biomethane consumption, the length of the gas pipeline for the biomethane supply, and the reduced costs to the gas supply system. A graph of the dependence of the critical length of the gas pipeline branch on the population size has been obtained, which makes it possible to determine the area of rational use of biomethane for gas supply to settlements. It was found that for a rural settlement with a population of 5,000 people, the critical length of the gas pipeline branch is 24.820–28.044 km, for an urban-type settlement with a population of 15,000 people, the length of the gas pipeline branch is 50.923–64.677 km, and for a city with a population of 30,000 people — 89.617–127.279 km. Conclusions. The results obtained can be used for the development and design of gas supply systems based on biomethane for the gasification of settlements remote from the main gas pipelines. The use of biomethane makes it possible to gasify settlements in developed agricultural regions and to increase the efficiency of the gas transportation system of the Russian Federation.

Between 2018 and 2023 the penetration rate of electricity smart meters in the European Union (EU) is expected to grow from approximately 44% to 71%. The unprecedently rapid development of smart metering (SM) as an ICT-enabled technological novelty is progressing in a complex, multi-actor innovation system, which is strongly driven by EU-level institutions and policies. This paper presents the comprehensive Technology Innovation System (TIS) analysis of electricity SM development in the EU, with a focus placed on regulatory aspects. The article identifies the key elements of the SM innovation system (technologies and infrastructures; actors and networks; institutions and policies) and characterises their interaction based on an in-depth desk research and a critical assessment of regulations, statistics and primary and grey literature sources (e.g., market reports). The main enablers and barriers for EU-level SM TIS development are studied. The major driving force for EU-level SM TIS is the clear, yet evolving vision of EU-level actors for the SM deployment, founded on the grounds of energy conservation and empowerment of customers. On the other hand, the major inhibitor is the insufficient regulatory framework for roll-outs at the level of a Member State, which does not fully ensure interoperability, data protection and security standards or organisational effectiveness.
