This paper is an attempt of authors to consider most likely scenario of the further development of street lighting systems, based on current trends in sensors, telecommunication technology and auto industry. Street lighting system previously already was considered as the element of the Smart City by researchers, however, the precise functionality, role and the importance of such a system was considered rather mediocre (ordinary). This article is a holistic view of the Smart Street management system with the street lighting system, which plays great importance of whole transportation and mobility infrastructure functionality and safety enhancement.

Power generation forecasting has always been a very important tool for the efficient management, operation and planning of small and large scale power systems. The smart grid architecture featuring electricity markets and distributed generation, with increasing penetration of Renewable Energy Sources, requires more accurate and faster forecasting algorithms. Meteorological parameters affect power generation in the case of conventional as well as Renewable Energy Sources. In this work, we propose the use of Kalman filters to correct the temperature forecast used to determine the expected output of a conventional gas turbine of a power plant participating in the wholesale electricity market in Greece. Time varying, time invariant and steady state Kalman filters are derived. The efficiency of the algorithms is tested through simulations. It is shown that the accuracy of the temperature forecast is significantly improved. The effect of the filtered temperature forecast on the expected of power output of a gas turbine is discussed.

In this paper, one technical gap of an indirect model predictive control (MPC) is discussed and a possible solution is proposed. A basic case study involving a traditional three-level h-bridge and a first order L filter was considered in order to magnify the effect of time horizon prediction and voltage over the regulated grid current waveform. An analysis related to the cost function composition over a horizon time prediction is then presented for different settings of the operational point. This paper presents only a part of obtained simulation results by means a model built a PSIM/Powersim. Even so, results show that one step forward could be classified as the most suitable form. And the number of involved applications could be even more since the fact that discussed results also indicate an unnecessity of higher processing time over several horizon time predictions for achieving the best results. Such conclusions would allow a smoother digital implementation of indirect MPC control method and result on a more efficient MPC controller in terms of energy effort in industrial applications.

Power factor correction feature became demanded in modern converters due to swift increase in penetration of electronic devices. At the same time, implementation of soft-switching modulation techniques allows to reduce the power losses in converters and increase their efficiency. Current source converters have native potential to implement both features. This paper compares well-known parallel resonant, newly emerged adaptive resonant and secondary-modulated topologies in order to evaluate the main benefits and drawbacks and determine the most suitable converters for AC-DC application with soft-switching and power factor correction.

This paper is dedicated to the experimental study of signal waveform and subcarrier number influence on the wireless power transfer (WPT) performance of prefabricated RF harvesting device - Powercast P2110B. This work has been carried out with two different waveform types - with low and high PAPR level. Moreover, the subcarrier number for both types has been varied from 8 to 32. Single tone signal was used as a reference for the result comparison and evaluation. The WPT experiment was performed with two different antenna types in the unlicensed ISM band in the frequency range from 863 to 868 MHz. The WPT study was conducted under real life scenario.

This document presents an approach for getting and calculation the parameters of Proportional- Resonant (PR) controller for the twisted-bidirectional buck-boost inverter based on unfolding circuit. The obtained results are suitable theoretical guidelines for an investigation of selected topology dynamic. The results of small signal model allow estimating the stability of the system. The simulation results of grid-connected inverter based on the PR controller are presented. As the result simple PR controller without any compensation block is stable, but can't provide high accuracy of the grid current in real experiment.

Key priority of the power industry is associated with power losses reduction during electrical energy transmission and distribution. Problem solution depends significantly on power grid companies' equipment with modern automated meter reading (AMR) technologies. The main approach for power consumption accuracy and meters conditions control is the balance method. The cost of electricity received from the AMR system data is used for the calculation of the controlled facility Electricity balances, load graphs geometric profile construction and power losses operational calculation are performed, the technical and commercial power losses are calculated, the factual and permissible non-balance are represented on the basis of the electrical circuit and power equipment passport data under study. The results presented in a visual interface allow making quickly decisions about the commercial data reliability and electricity metering system serviceability. Power unbalance cases were detected on identified intervals where the accounting system worked correctly. All detected unbalance cases were anchored to place and time. A three-level metrological characteristics control system prototype was made in infographic format. Balances and losses rapid calculation at hour and less time intervals allows detecting malfunctions in AMR systems performance and taking measures for their elimination.

The successful career of graduates, which focus on development and maintenance of adaptive systems, apart to the main background in electrical engineering, requires strong abilities to work with users of developed device, entrepreneurship skills, knowledge of marketing and ability to develop market oriented product. This paper demonstrates the approach, which encourages creative skills to build the prototypes of new products, motivates students to create new ideas for start-ups, and allows to develop entrepreneurship skills during the education process. The case study of the Riga Technical University RTU master level program “Adaptronics” concerning the development of entrepreneurship skills is described in this work. The case study of student’ survey at the University of Split is also discussed in the paper. The survey results demonstrate the students' level of entrepreneurial orientation in correlation with their working experience and their perception about opportunity to find a job after graduating the university.

The ascending trend in retail electricity prices since the first energy package is often blamed on the market reforms and the cost of a low carbon economy. The present study analyzes EU-28 statistical data on retail prices for the medium households and industries, for the years 2008–2017, a period of economic slowdown. We focus especially on six countries, Austria, Denmark, Germany, Greece, Latvia and Spain and examine retail prices against the degree of renewable energy sources (RES) penetration and the market liberalization in each country. We also examine the cases of three Western Balkan countries that still have a very low degree of liberalization. The increasing percentage of RES in electricity generation, the number of retailers and the market share of the main retailer are analyzed with respect to the retail electricity price for the period studied. In spite of the different specifics of each country's economy, there are certain common trends. The price increase has been found to be the result of levies and taxes, rather than the energy cost, with the burden carried mostly by households. In the cases studied here, the increase correlates with either the increase in RES or increased competition or both depending on the market structures in place during the examined period and the maturity and performance of the measures towards a liberalized electricity market and a low carbon economy.
