Improving the efficiency of using small-distributed generation systems through mechanisms of demand management for electricity and gas

Making a breakthrough in the energy industry is a particularly laborious cross-disciplinary challenge due to the extreme complexity of production systems and the necessity to ensure the compatibility of a huge number of technologies and industrial and managerial systems of various nature. This makes it highly relevant to provide knowledge-intensive support for teams that implement projects aimed at breakthrough transformations. This article describes a specialized science and education platform that is being rolled out by the authors at a number of major energy companies in Russia and at Ural Federal University. The platform has features of a communications platform that brings together science, education, and energy companies, and of a digital ecosystem that serves as a framework for customized services for stakeholders. The platform uses an operation mechanism that is designed to ensure the reproduction of knowledge that is in line with corresponding trends and changes emerging in the global, national, and industrial contexts, and promptly converts it into learning content and a project agenda for breakthrough teams. An original methodology for the training of breakthrough teams and arguments for the appropriateness of using a platform-based approach in order to increase intellectual capital in the energy industry constitute the scientific novelty of the article. This article has a practical value to it as it demonstrates the scaling capability of the elements of the conceptual model, of its operation mechanism, and the best practices of using a science and education platform as the organizational basis for breakthrough projects in the energy sector.

“…A standard set of formulas and technical and economic coefficients is used (operating expenses and capital expenditures; standard, excessive, and actual heat losses; undersupply of energy; mean downtime). The approach can be used as part of any energy asset management strategy (preventive maintenance, time-based maintenance), as well as in more advanced strategies such as condition-based maintenance [9,10].…”

The reliability of heat supply in cities is largely determined by the actual condition of pipelines, for example, corrosive and erosive wear. Comparative analysis of methodological approaches to assessing the technical condition of district heating networks shows that the most innovative and effective approach is internal pipe inspection using non-destructive magnetic testing. The article presents the results of research tests of the method in the context of its use for maintenance and retrofitting of the heating infrastructure in Yekaterinburg, a Russian city with a complex topology of utility networks and extremely uneven tear and wear on some sections of the networks. The authors describe the technical and economic peculiarities of using internal pipe inspection methods at various stages of testing and formulate qualitative and quantitative criteria for assessing the effectiveness of the method being presented. Recommendations have been suggested for the optimum application of the method by heat network operators, especially those operating and servicing district heating systems.

“…International experience shows that the digital transformation of grids results in lower power losses, higher reliability and accessibility of power supply and creates a number of additional services for customers [5][6][7]. The adoption of digital technologies entails savings in the course of the implementation of investment programs and opens up opportunities for the accelerated expansion of power distribution infrastructure, ensuring higher profitability of the energy business and reducing SAIDI/SAIFI and preparing energy companies for new technological challenges [8][9][10][11].…”

The digitization of power grids envisages a transition to new models of fault diagnosis, repair and maintenance of electric power grid equipment. The most promising tools for implementing advanced production asset management strategies are integrated technologies that are based on robotic diagnostic platforms, various hardware-software instruments and smart data analysis systems. The article analyzes other countries' experience of developing robotic methods of fault diagnosis and maintenance of overhead power transmission lines, which present a major challenge in terms of monitoring, failure prediction and localized repairs. The Cablewalker robotic system was used as an example for identifying the advantages of integrated diagnostic hardware systems as opposed to traditional methods of power grid equipment maintenance and overhaul. Recommendations are given for adopting the technology in grid companies. During trials of the technology on a 2.34-km section of a power transmission line 112 defects were detected versus three that were identified by means of 'manual' inspection. A digital twin of the transmission line was created to manage its technical condition with regard to various risks.
