The paper describes the possibility of hybrid electricity generation in already existing wind power plants (WPP) by additional installation of photovoltaic power plants (PVPP) on individual wind turbines (WT). Wind turbines have the lowest generation of electricity in the summer months, while PVPPs have the opposite, the highest generation in those months. Connecting the PVPP to the existing WT (hybrid electricity generation) brings a more even generation and a greater degree of use of the infrastructure of the existing wind farms (HV/MV transformer station, medium voltage cable distribution...). This way the variation of generation in relation to the average annual generation is reduced, which reduces the problems of balancing electricity.

The electrification of public transportation fleets worldwide can pose a challenge to multiple stakeholders, such as the fleet operator or the operator of the local electrical grid. One of the important prerequisites for the successful integration of these fleets into the existing system is the knowledge of the energy consumption of the buses during their trips. The energy consumption varies depending on multiple factors such as the vehicle or route-related parameters, operational, and environmental parameters. This paper gives an overview of the latest research regarding these influential factors. Another essential prerequisite for the implementation of intelligent management systems for electric bus fleets is the forecasting of energy consumption. Researchers take different approaches to tackle this issue. A review of the latest research considering empirical approaches, physical models, regression, and machine learning is also provided in this paper. The findings of this paper provide a quick overview of different aspects of the energy consumption of electric buses and can therefore support other researchers or decision-makers in their work.

Governments in the region are actively trying to decentralize production in the energy sector by encouraging the construction of power plants using renewable energy resources. The Network Code [<xref ref-type="bibr" rid="j_bhee-2023-0008_ref_001">1</xref>] and the Connection Regulation [<xref ref-type="bibr" rid="j_bhee-2023-0008_ref_002">2</xref>]-[<xref ref-type="bibr" rid="j_bhee-2023-0008_ref_004">4</xref>] define the procedure for issuing connection conditions to the power transmission network in Bosnia and Herzegovina. This paper will demonstrate the necessary approach to assessing the possibilities of connection and placement of the produced power and energy at a specific connection point in the early stages of planning, using the example of an 80 MW photovoltaic power plant planned for construction in the municipality of Tomislavgrad. The connection of the power plant is planned on a 110 kV voltage level network, by connecting it to the target 110 kV overhead transmission lines, following the principle of input-output.

Using three-dimensional full-wave electromagnetic simulations with Ansys HFSS, this paper analyses the effect of the actual design of a small power transformer on the propagation of ultra-high frequency (UHF) waves from a partial discharge (PD) source to four UHF antennas. Based on these results, the goal is to localize the source of PD. Three power transformer models of different complexity are used to do that. Due to the effects of their all taken into account reflections and diffractions caused by the metal parts in the power transformer, the received PD waveforms at UHF sensors are distorted to an appropriate extent. Time differences of arrivals (TDOAs) of the signals at pairs of four simulated UHF sensors are investigated to estimate the location of the PD source. The benefits of this assessment of the PD source location using this simulation software are analysed.

Power swing is a phenomenon that is basically caused by large disturbances in the power system. If not blocked, it can cause incorrect operation of distance protection and result in incorrect or unwanted disconnection of transmission line switches. Furthermore, if not prevented, it can lead to serious damage to the generator. This paper describes the basics of power system stability during power swings, lists the effects on the distance or other relay during power swing, and presents methods for detecting power swing, both traditional and advanced. Additionally, it provides a description of the settings of the Power Swing Blocking (PSB) scheme to meet these requirements.

Within this paper, the possibility of using advanced LoRa technology in the field of long-range remote control was considered. For testing purposes, a one-way point-to-point LoRa remote control link was implemented based on the LoRa Ra-02 SX1278 transceiver and the corresponding 32-bit Cortex-M3 microcontroller. The remote control application software is developed in the Arduino development environment. The implemented link was tested experimentally to check the range, data transfer speed and link stability. Test results show that LoRa transceiver modules can be used in the field of long-range remote control.
