  • Will NILM Technology Replace Multi-Meter Telemetry Systems for Monitoring Electricity Consumption?
    Publikacja

    - ENERGIES - Rok 2023

    The estimation of electric power utilization, its baseload, and its heating, light, ventilation, and air-conditioning (HVAC) power component, which represents a very large portion of electricity usage in commercial facilities, are important for energy consumption controls and planning. Non-intrusive load monitoring (NILM) is the analytical method used to monitor the energy and disaggregate total electrical usage into appliance-related...

  • New Performance Indices for Power System Stabilizers
    Publikacja

    - ENERGIES - Rok 2022

    The subject of the article is issues related to innovative indices for power system stabilizers (PSSs). These new indices will be able to quickly show which PSS (among many other PSSs) is not working properly and that advanced optimization and simulation methods should be used to improve the PSS settings. The authors note the fact that the acceptance requirements for PSSs are different in various power systems. Moreover, the authors...

  • Distribution Transformer with Multi-Zone Voltage Regulation for Smart Grid System Application
    Publikacja

    - Rok 2019

    The article presents four concepts of the multi-zone voltage regulation (MZVR) system. It is a combination of a distribution transformer with an on-load tap-changer, for step voltage regulation, and a power electronic converter, dimensioned for a fraction of MZVR power, realizing continuous voltage regulation, supplemented by a special switch, the so-called bypass. This allows voltage regulation at high resolution, wide range and...

  • Real-time hybrid model of a wind turbine with doubly fed induction generator
    Publikacja

    - Rok 2019

    In recent years renewable sources have been dominating power system. The share of wind power in energy production increases year by year, which meets the need to protect the environment. Possibility of conducting, not only computer simulation, but also laboratory studies of wind turbine operation and impact on the power system and other power devices in laboratory conditions would be very useful. This article presents a method...

  • Transformatory z regulacją przekładni pod obciążeniem w systemie elektroenergetycznym
    Publikacja

    - Rok 2019

    Zmiany zachodzące w systemie elektroenergetycznym, związane między innymi ze stałym wzrostem zapotrzebowania na moc, przyłączaniem źródeł odnawialnych czy rozwojem elektromobilności, przy jednoczesnym wzroście wymagań dotyczących jakości energii elektrycznej, zmuszają operatorów sieci elektroenergetycznych do podejmowania działań zmierzających do sprostania nowym wymaganiom. Jednym z kierunków tych działań jest wykorzystanie w...

  • Voltage Source Power Line Conditioner for Applications in Local Supply Systems
    Publikacja

    - Rok 2019

    The paper presents the basic principles of operation of voltage source power line conditioners (VSPLC) as well as their energy and filtration properties. A 4-level cascade based Voltage Source Converter (VSC) is used as a voltage source. The advantages of this topology is relatively simple construction and simple way of balancing DC link voltages. Results of the theoretical and experimental investigations confirm good energetic...
