TL;DR: The focus areas of this review study are distributed generation, microgrids, smart meters’ deployment, energy storage technologies, and the role of smart loads in primary frequency response provision.
Abstract: The future power system must provide electricity that is reliable and affordable. To meet this goal, both the electricity grid and the existing control system must become smarter. In this paper, some of the major issues and challenges of smart grid’s development are discussed, and ongoing and future trends are presented with the aim to provide a reader with an insight on the relevant research topics, challenges and actual engineering tasks in smart grids. The focus areas of this review study are distributed generation, microgrids, smart meters’ deployment, energy storage technologies, and the role of smart loads in primary frequency response provision. The exploration of smart grid technologies and distributed generation systems has been accomplished, and a general comparison of the conventional grid and a future smart model is included. The issue of increasing penetration of renewable energy sources to the power system and posers related to the integration of distributed generation are also presented.

TL;DR: A system of criteria for the selection and assessment of HW/OS routes, which would allow selecting the most appropriate route of transportation in terms of cost and time, is drawn up and can be practically applied to any territory.
Abstract: The improvement of transportation systems and technologic equipment leads to changing technical capabilities of this equipment. With the development of technologies, industrial development is also inevitable, resulting in correspondingly increasing need of transportation of HeavyWeight and OverSize (HW/OS) cargo. The application of a systematic approach in HW/OS cargo transportation processes allows reducing costs of delivery of such a cargo several times, which leads to a dramatic change of economic development and investment attraction conditions. Thus creating a system of criteria for the selection and assessment of HW/OS routes, which would allow selecting the most appropriate route of transportation in terms of cost and time, is expedient for this reason. The algorithm for the assessment of HW/OS cargo transportation routes will be drawn up in this article. This algorithm enables an objective evaluation of HW/OS transportation processes comparing different modes of transport, route segments, cargo transportation and cargo handling technology, and it can be practically applied to any territory.

TL;DR: In this article, the effect of hydrogen absorbed by metal on the variation of the structure and mechanical properties of the main gas pipeline after a long-term operation is found. But the main regularities in the graded nature of the static deformation process and the impact of hydrogenation on the scattered damage and fracture accumulation are found.
Abstract: The effect of the in-service scattered damage in the pipe wall metal is evaluated, and the effect of hydrogen absorbed by metal on the variation of the structure and mechanical properties of the main gas pipeline after a long-term operation is found. The main regularities in the graded nature of the static deformation process and the effect of hydrogenation on the scattered damage and fracture accumulation are found.
