    Cloud-based System for Real-Time Reading of Smart Meters’ Data over 5G New Radio
    (2021) Forcan, Miodrag; Maksimović, Mirjana; Forcan, Jovana; Jokić, Srđan
    The potential of the combined application of Cloud computing and the fifth generation of cellular network technology (5G) in Smart Grid (SG) could be revolutionary in terms of empowering the Advanced Metering Infrastructure (AMI). The model of a real-time 5G-based communication system for remote reading of Smart Meters’ data is developed and presented in this paper. Online monitoring of power demand has been performed using the Cloud-based platform ThingSpeak. The proposed 5G communication model and online monitoring function have been tested and validated using a power demand variation scenario in a well-known IEEE 13 node network. The obtained results confirm the model accuracy and reveal the potential of AMI based on realtime data transmission between Smart meters (SM) and Cloud computing platform using a 5G communication network.

    ENERGY INDEX FOR THE PRODUCTION OF WOODEN CHIPS
    (University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2015) Vasković, Srđan; Gvero, Petar; Medaković, Vlado; Halilović, Velid; Ikić, Marko; Jokić, Srđan; Kalabić, Dragana
    Production of solid fuels from wooden biomass is defined with appropriate energy chain of supply. Procedure for production of solid fuels from wooden biomass, starting with technology for gathering wooden residues and residues from logging up by the system of fuels production (system for milling, crushing, chopping, drying and pressing of wooden residues), presents energy chain of supply with solid fuel from biomass. Efficiency of production wooden chips is the relation of overall invested energy per 1 kWh of lower heating value of produced fuel. This paper will analyze total invested energy in supply chain for production wooden chips as a function transport distance and wood moisture. Paper will mathematically describe chain of wooden chips production from forest transported to the sawmill and to the terminal of processing. Mathematical model for calculation energy index developed in Mathcad software.
