Thermal aging management for electricity distribution networks: FEM-based qualification of underground power cables
(Thermal Science, 2022-03)
It is well-known that there is no PLAN-DO-CHECK-ACT (PDCA) approach that is used by electricity distribution network operators and asset managers of power cable systems. Accordingly, this paper proposes a novel application ...
A Novel Procedure for Quick Design of Off-Grid PV Water Pumping Systems for Irrigation
(Elektronika ir Elektrotechnika, 2021-03)
It is known that meteorological variables from meteorological online services can be used for the design of photovoltaic (PV) water pumping systems for irrigation. The software LORENTZ COMPASS in such a manner uses as ...
Eliminating the effect of hot spots on underground power cables using cool pavements
(Electrical Engineering, 2019-10-24)
It is well known that hot spots limit the ampacities of underground power cables. There are many commonly applied methods
to control the thermal environment in hot spots of underground power cables. However, applications ...

Optimal Placement and Sizing of Inverter-Based Distributed Generation Units and Shunt Capacitors in Distorted Distribution Systems Using a Hybrid Phasor Particle Swarm Optimization and Gravitational Search Algorithm
(Electric Power Components and Systems, 2020-08)
In this paper, a novel hybrid population-based meta-heuristic algorithm, called the hybrid Phasor Particle Swarm Optimization and Gravitational Search Algorithm (PPSOGSA), is proposed to solve the problem of optimal placement ...
Voltage regulation in LV distribution networks with PV generation and battery storage
(Journal of ELECTRICAL ENGINEERING, 2021-12-22)
High penetration of photovoltaic (PV) generation in low voltage (LV) distribution networks can leads some power quality problems. One of the most important issues in this regard is the impermissible voltage deviation in ...
Solving combined economic emission dispatch problem using Adaptive Wind Driven Optimization
(Turkish Journal of Electrical Engineering and Computer Sciences, 2018-03)
In this paper, the adaptive wind driven optimization (AWDO) algorithm is applied for solving the combined economic emission dispatch (CEED) problem. AWDO is one of the newest hybrid algorithms, which optimizes the selection ...
Modelling of hydrochemical and hydromechanical parameters’ synergism in the process of solid deposit creation in geothermal and other hard waters
(Journal of the Serbian Chemical Society, 2018-01)
This paper presents the experimental research results, regarding the effect of hydromechanical parameters and based on the relative reduction of the starting hardness of geothermal water of Sijarinska Banja and Niška Banja ...
Experimental Study of the Phase Equilibria in the Ternary Ga-Ge-Zn System
(Journal of Phase Equilibria and Diffusion, 2022-04)
In the current study the ternary Ga-Ge-Zn system was experimentally and analytically tested. The ternary system is chosen due to the importance of germanium-based alloys in the electronic industry and their special application ...
