Their interconnection to the AC grid relies on dedicated inverters that pose several challenges in terms of lower inertia and poorer power quality.

To fill the standardization gaps, the paper discusses the suitable definition of DC power in distorted conditions and evaluates the possible measurement errors due to real-world disturbances.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115793905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this framework, the active customers are subject to demand response programs used to efficiently reduce the amount and timing of electricity consumption. The main requirements for residential demand response programs are acquiring real-time electricity consumption data and load profiles of residential appliances. Development of communication technologies and smart load monitoring applications has simplified the access to this information. This paper investigates and describes the design of a developed data acquisition and monitoring system for demand response implementation in the residential sector. Our smart monitoring system integrates a number of residential electric appliances to study their daily energy consumption profiles and, in the future, forecasts their potential demand response capacity. We describe the design of a LabView application for acquiring, logging, processing and visualizing data derived from the Demand Response Laboratory (DR Lab) at the University of Zagreb Faculty of Electrical Engineering and Computing (UNIZG-FER). The monitoring system is implemented in a way that enables an-cillary service provisioning and participation in demand response programs.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129320951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a simple framework based on open-source codes that can convert a typical laboratory oscilloscope to a synchrophasors logger with minimum investment and use devices commonly available in electrical engineering laboratories. We use simple algorithms to extract electrical quantities of interest and log them to a highly efficient time-series database.

Phasor Measurement Units (PMUs) are well-known devices that are proven to be particularly effective in this context. However, it is more and more essential to assess the reliability of these measurements, especially in low-inertia and transient conditions. Therefore, this paper presents a study on the feasibility of aggregating PMU-based measurements performed in different nodes of a distribution grid. The results indicate the significance of evaluating such quantity for correct control at a local level, mainly where an extensive installation of renewables is present.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117001550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TEVR is caused by very high frequency overvoltages (the order of MHz), for which even small inductance of earthing leads can represent significant impedance. The level of TEVR strongly depends on design and length of the earthing leads. Therefore, overvoltage measurements were performed for different earthing leads configurations in 110 kV GIS and results are presented in this paper. The earthing leads configurations were first verified by simulation in the EMTP program.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131867058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, road safety is increased, and complex traffic management is enabled. However, we are moving one step further and proposing the usage of vehicle resources, such as computing capabilities and data storage, for enabling vehicular clouds which can efficiently support smart transportation infrastructure. The main goal for establishing vehicular clouds is utilization of vast amounts of unused hardware resources available at vehicles for enabling and supporting smart transportation infrastructure. Vehicular clouds can enable additional distributed computing and storage resources to various groups of users, as well as introduce new use cases and applications. Recent vehicular cloud computing methods and models, as well as vehicular cloud computing architecture and services are explored in this paper. Based on the research and our work a new vehicular cloud computing architecture VANET-CC is proposed and elaborated. Furthermore, possible services for cloud computing are pointed out together with vehicle management in such clouds.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main components of a power transformer is its core, which is made of thin stacked sheets of steel. Due to the complexity of the manufacturing process and the dimensions of sheets and the overall core, the whole stacking process needs to be precise and have relatively low tolerances. All of this dictates a relatively big number of control parameters and measurements during the core manufacturing. Therefore, it is of importance to devise the methodology and smart devices that can speed up the measurements and help in increasing the measurement quality and worker safety. This paper presents such an approach, by showing custom-built devices for that purpose, together with the accompanying software.","PeriodicalId":286515,"journal":{"name":"2023 4th International Conference on Smart Grid Metrology (SMAGRIMET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125276928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
