Nowadays, one of the most imminent problems facing power systems in post-industrial countries is the sustainable development of power systems under conditions of increasing power consumption irregularity due to the reduction of the industry's share in consumers' demand for electric power. In today's Russia, this issue is becoming very acute due to the significant share of electric power and heat co-generation that is demonstrating low manoeuvrability and poor adaptation to operations in the daily variation of electric power demand. This paper considers the problem of improving the power system steady-state through the optimization of the production structure of thermal power plants. We propose a combinatorial algorithm that improves the planning of the structural and technological modernization of the power equipment configuration, with a glance at the forecast of the increasing irregularity of power consumption.

Major shifts in the competitive environment encouraged a recent growth in the number of academic articles devoted to strategic aspects of asset management. Organizations start to recognize that a strategic approach to asset management becomes a source of sustainable competitive advantages and long-term survival in the turbulent environment. However, existing studies are largely case-specific in interpreting strategy and draw on various theoretical grounds and approaches. This leads to little theoretical and methodological consistency in understanding current findings and how to design future studies. The key goal of this paper is to systematically review the existing research through the analysis of over 700 articles devoted to asset management with a focus on strategic aspects. Our key contributions are positioning strategic asset management within the vast field of asset management research, describing the nature of strategic asset management research, and confirming that asset management strategies align with different levels of organizational strategy. We visualize the existing research field, and indicate gaps and underdeveloped areas of research. We also shortly outline future research directions based on our findings, thus encouraging a more coherent development of research on strategic asset management.

This article aims to investigate the role of waste management in the development of modern green and smart cities and to determine the existence of several key points in programs transforming cities into green cities with smart technologies. The relevance of the research is determined by the need to develop a theoretical and methodological basis for the green and smart city concepts. The research process involved the following methods: Scientific analysis, comparison, and synthesis. The research results of the case study of Russia determined that for urban territories with great distances between urban districts, waste sorting stations should be located as parts of so-called waste recycling complexes at intermunicipal landfills. This will allow a more fully implementation of the concept of recycling economy not only in Russian cities, but also in other cities with sparse populations across the world. Further, the authors conclude that the effectiveness of green technologies in modern cities, especially in waste management, depends on the level of participation of citizens. People are active participants in the life processes of cities and have a direct impact on the urban environment. Consequently, the introduction of green technologies can only be achieved in harmony with the well-established behavioral attitudes of city residents together with the implementation of green and smart urban technologies.

The paper is devoted to the assessment of the prospects of implementing clean energy sources in Russia, where the current energy policy goal is to increase the role of renewable and clean energy sources. The research is based on data from the Krasnoyarsk Region as one of the largest territories but also as a representative model of Russia. The aim of the study is to identify where and which renewable energy source (solar, wind, hydro and nuclear) has the highest potential. The novelty of our research lies in its holistic nature: authors consider both geographical and technical potential for renewable energy sources development as well as prospective demand for such resources, while previous research is mostly focused on specific aspects of renewable energy development. We also consider the level of air pollution as an important factor for the development of renewable energy sources. The results of the study show that there is a strong potential for clean energy sources in the Krasnoyarsk Region. The resulting matrix identifies the potential of energy sources across all the municipal entities and also indicates whether the source of energy is primary or supplemental and where several sources may be implemented in cooperation.

Over the last decade, academic literature has seen a boom in the number of publications devoted to the notion of ecosystem, which has resulted in the emergence of various research streams and the corresponding fragmentation of the research domain. The existing variation in meanings and contradictory definitions shows the need for a thorough literature review on the three tightly related concepts of innovation ecosystem, business ecosystem and entrepreneurial ecosystem. This study is based on a mixed technique, which combines a bibliometric analysis and an in-depth investigation of papers devoted to these research streams. Through examining their theoretical background, constructing conceptual structures and performing an in-depth analysis we were able to define the essence of innovation, business and entrepreneurial ecosystems as well as their distinctive features. We then proceeded with a comparative analysis of these concepts, which allowed us to outline the existing similarities and to demarcate the concepts from an ontological perspective. This study provides definitive clarification regarding the existing conceptual mix in the field of ecosystem research, and can be used as a foundation for a further investigation of the concept.
