“…67 (3) 2019 studied one-way resource sharing and power transfer through a multi-direction Gaussian channel using multiple access techniques [9]. This was extended to a cooperative energy model based on two-way energy transfer pattern by Hussein Al Haj [5]. The valuable cooperative energy approach by Liu [10] was implemented based on CDMA/OFDMA multiple access techniques and on relay-based multiple access channels in the networks.…”

In this study, the concepts of simultaneous user association and resource allocation in non-orthogonal multiple access systems have been investigated. Subscribers are randomly distributed in them. In the paper, a novel cooperative energy harvesting model is introduced so that user equipment near to the base stations acts as relay for further subscribers. In order to consider the local limitations of alternative energy resources, it was assumed that alternative energy would be shared among the base stations by means of the dynamic grid network. In this architecture, non-orthogonal resource allocation and user association frameworks should be reconfigured because conventional schemes use orthogonal multiple access. Hence, this paper suggests a novel approach to joint optimum cooperative power allocation and user association techniques to achieve a maximum degree of energy efficiency for the whole system in which the quality of experience parameters are assumed to be bounded during multi-cell multicast sessions. The model was also modified to develop joint multi-layered resource control and user association that can distinguish the service pattern in cooperative energy heterogeneous systems with non-orthogonal multiple access to obtain more resource optimality than in the current approaches. The effectiveness of the suggested approach is confirmed by numerical results. Also, the results reveal that non-orthogonal multiple access can provide greater energy efficiency than the conventional orthogonal multiple access approaches such as e.g. the MAX-SINR scheme.

“…However, introducing three-level configurations into low-voltage converters is questionable as better voltage and current parameters are noted both at the power network input and output. Configuration of a low-voltage converter operating in a 3£400 V or similar power network depends on its application, in particular its power level [1,9,10,16].…”

The article presents the analysis of the simulation test results for three variants of the power electronics used as interface between the power network and superconducting magnetic energy storage (SMES) with the following parameters: power of 250 kW, current of 500 A DC and voltage of 500 V DC. Three interface topologies were analyzed: two-level AC-DC and DC-DC converters; three-level systems and mixed systems combining a three-level active rectifier and a two-level DC-DC converter. The following criteria were considered: input and output current and voltage distortions, determined as THD i and THD u , power losses in power electronics components; cost of the semiconductor components for each topology and total cost of the interface. Results of the analysis showed that for high-power low-voltage and high-current power electronics systems, the most advantageous solution from a technical and economical perspective is a two-level interface configuration in relation to both AC-DC and DC-DC converters.

on the series connection of power modules using standard low-voltage components. It allows for low THD output voltages and input currents, reduction of passive components and redundancy of components. Thanks to these features, the cascaded multilevel converters have been recognized as attractive solutions for HVDC transmission, SST and photovoltaic (PV) systems. The timely problem of how to interface different types of energy storages with power grid is addressed by an exceptionally experienced team of specialists: A. Domino, K. Zymmer and M. Parchomiuk from the Electrotechnical Institute (IEL), Warsaw, Poland [5]. They present an overview of converter topologies for energy storage, such as superconducting magnetic energy storage (SMES), supercapacitor energy storage (SES) and chemical batteries. Tech. 59 (4), 2011. The newest Special Section is intended to focus on recent research and trends in application of multilevel converters. Multilevel converters have been extensively developed over the last two decades and show several important advantages of power electronic circuits, such as: operation at high voltages, harmonics reduction, higher efficiency, modularity, smaller size and lower cost. Also, thanks to increasing interest in renewable energy systems (RES) and SGs, the development of multilevel converters is considerably accelerated. The papers included in the presented special section are grouped into the main categories that follow. . Some limitations on application of such inverters for precision drive control in optical telescopes were specified. Modern predictive control methods developed for Special issue of high power multilevel converters [11-15].The design and investigation results of switched capacitor voltage multipliers for application in high power systems is presented by the team of outstanding specialists from AGH University of Science and Technology, Krakow, Poland [11]. The considered family of multilevel converters includes classical topologies and also novel concepts. The application of thyristors as well as invention of novel concepts of multiplier topologies with appropriate control make it possible to achieve high efficiency, high voltage gain, as well as reliable and simple DC-DC converters for high power systems. The fundamental problem of how to increase the DC fault ride-through capability of a full-bridge modular multilevel converter (MMC) station while ensuring a stable controlled operation as a STATCOM during DC faults without the need for fault isolation is deeply discussed and well illustrated by the international team of excellent researchers E. Kontos, and P. Technology, Poland, the control strategy for power electronic transformer (PET, also known as SST) is proposed. The analyzed structure uses two 7-level cascaded H-bridge (CHB) rectifiers. The electrical power is transferred between DClinks of CHB converters using dual-active-bridges (DABs) and low voltage high frequency transformers. The system allows to control the active and reactive power with low level of harmonic ...
