The article discusses nonlinearity correction methods in power amplifiers of complex multi-frequency signals used in digital broadcasting. These signals have a large peak factor and high sensitivity to the nonlinearity of the power amplifier. Various circuit solutions and digital signal processing algorithms are used to compensate for these nonlinearities. One of the most perspective approaches is the digital signal predistortion method. It represents the following: distortions are introduced into the digital signal, subsequently compensating for the nonlinearity of the power amplifier. Also the article discusses various algorithmic methods for digital predistortion of signals, in particular, Volterra series, LUT tables, and perspective neural networks. The modeling features of modern power amplifiers are analyzed.

Dynamic capacity rating technologies of power lines has been growing in the electric power industry since 1977. Yet, its use is absent in Russia. In this study, a methodology for calculating the dynamic line rating is presented. The economic benefits related to the use of a dynamic line rating instead of the conventional static line rating is assessed for simple-but-illustrative two-zonal network representing Russia power corridor that connects Siberian and European zones. Our simulations show that the use of dynamic line rating, in comparison with a static one, results in economic savings for all the months of the year, reaching as high as 8%.

In this paper, we propose an approach for estimating multi-objective operational efficiency of microgrid. The proposed approach is based on analyzing various microgrid components in the form of distributed intelligent agents in a framework of multi-agent system (MAS), which allows evaluating the operational efficiency of agents individually, as well as the efficiency of the microgrid as a combined system. Moreover, we introduce a novel unified agent representation, appropriate for a variety of dynamic systems containing a combination of both continuous and discrete event processes. The elaborated scheme gives the possibility to formalize the process of integrating heterogeneous objective functions into certain combined criteria. Different efficiency criteria are considered in this work: technical, economic and ecological. The algorithm of microgrid efficiency estimation is carried out based on an application of designing an eco-friendly hybrid power generating system, producing electricity and heat in Arctic enclave.

The paper presents the results of developing a decoder architecture of low-density parity check code of the DVB-S2 standard for field programmable gate array. It supports several code rates and codeword lengths described in the appendix of the standard. The proposed decoder architecture has a partially parallel structure, which allows to achieve high decoding performance and efficient use of chip area. The presence of double-diagonal submatrices in the structure of the parity check matrices was also confirmed, and a method for eliminating them was implemented. In the work, an analysis of parameters affecting the static and dynamic power consumption in the field programmable gate array was made. Based on it, algorithmic and architectural methods for reducing consumption are proposed. The paper describes the developed architectures and methods to reduce chip power consumption.

Distributed Generation (DG) is an essential part in power systems. DG gives provision of an equivalent to the usual electric origins like oil, gas, water, etc. DG distribution is used to gear the reliability of a power distribution system. This is done with the help of reduction of outages or sudden interruptions which usually happen because of failure in the transmission or distribution systems. In this study, the reliability indices of a 132 KV Grid Station have been found out and by using those indices, it is analyzed that how the reliability of a distributed generation system can be improved with the help of System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), Customer Average Interruption Duration Index (CAIDI), Estimated Energy Not Served (EENS) and Average Service Availability Index (ASAI).

The paper outlines a concept of reducing economic losses resulting from damage in power grids when predicting future repair and renovation works. Increased economic losses caused by electric energy undersupply and the cost of emergency operations result in a steady increase in the unit cost of electric energy. The authors present an algorithm of the effective optimization of repair works carried out in power grids with a voltage of 6–10 kV. The main idea of the proposed algorithm is to introduce a multi-criteria evaluation system, which, in some respects, can be quite promising when applied in power grids of the Russian Federation. Based on the assessment made, the authors have worked out a phased repair plan of the most important and damageable power grid nodes, the failures of which may lead to considerable economic losses.

The study of transients with various types of short circuit is a difficult task. During transients, dangerous overvoltage's can occur in the system, several times higher than the levels for which the network isolation and its protection are designed. Improving the design and operation of complex electric power systems (EPS) is associated with the need for continuous development and improvement of calculation methods and analysis of steady and transient conditions. The successful solution of these problems substantially depends on the effectiveness of mathematical models for studying various EES modes and the versatility of the calculation algorithm. Therefore, this article presents a mathematical model and calculation algorithm for the study of transients with various types of short circuit.
