Item Comprehensive Assessment of Smart Grids: Is There a Universal Approach?(Energies, 2021) Люльов, Олексій Валентинович; Люлев, Алексей Валентинович; Liulov, Oleksii Valentynovych; Вакуленко, Ігор Анатолійович; Вакуленко, Игорь Анатолиевич; Vakulenko, Ihor Anatoliiovych; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Квілінський, Олексій Станіславович; Квилинский, Алексей Станиславович; Kwilinski, Aleksy; Dzwigol, H.; Dzwigol-Barosz, M.A comprehensive assessment of smart grids is critical for their development. Existing scientific research testifies to the urgency and complexity of the problem of implementing smart grids effectively, both in terms of a single project performance and from the standpoint of creating a local, and later global, energy system. The multidimensionality of smart grids makes it challenging to assess the effectiveness of their implementation. Difficulties in evaluation arise because it is challenging to consider technical, technological, economic, and other relevant aspects of smart grids’ development within a single evaluation system. There are currently a significant number of smart grid assessment systems. However, it remains debatable how systematically and comprehensively they measure the efficiency of a smart grid. This, in turn, raises the question of whether there is a universal evaluation system that integrally considers all the crucial components of smart grids and is suitable for evaluating smart grid projects of different content. This article analyzes the most well-known approaches to comprehensive assessment of smart grids according to the completeness of their coverage of smart grids’ most critical components. This paper identifies the essential areas for assessing smart grids according to the most cited and authoritative research and regulatory documents of the European Union. As a result, seven groups of indicators were identified. These groups of indicators are the basis for comparative analysis of the comprehensive assessment approaches of smart grids. The results of the study should help determine the appropriateness of applying a particular evaluation system. In addition, the analysis of existing evaluation systems allows the shaping of a universal approach to evaluating smart grids comprehensively and systematically.Item Comprehensive Assessment of Smart Grids: Is There a Universal Approach?(MDPI Publishing Services, 2021) Люльов, Олексій Валентинович; Люлев, Алексей Валентинович; Liulov, Oleksii Valentynovych; Вакуленко, Ігор Анатолійович; Вакуленко, Игорь Анатолиевич; Vakulenko, Ihor Anatoliiovych; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Квілінський, Олексій Станіславович; Квилинский, Алексей Станиславович; Kwilinski, Aleksy; Dzwigol, Henryk; Dzwigol-Barosz, MariolaA comprehensive assessment of smart grids is critical for their development.

At the same time, reinforcing of environmental conflicts, increasing tendency of energy consumption and greenhouse gas emissions requires a primary focus on the formation of effective mechanisms for solving and energy problems and providing energy security. In this direction, the formation of a fundamentally new model of stakeholder interaction in providing the country's energy security by minimizing the existing energy efficiency gaps (mismatch between optimal and actual energy efficiency levels in the absence of opportunistic behaviour of stakeholders), modelling explicit and making energy-efficient decisions; constructive modelling of causal socio-ecological economic interdependencies in energy-efficient decision-making in the state-business-society chain. In this case, it is necessary to develop the economicmathematical model for checking the causal links between stakeholders in energy efficiency decisions, which will describe and formalize the patterns of complementary effects and risks of energy efficiency decisions to achieve a balance between optimal and current levels of energy efficiency. The authors proposed to develop the optimal and time-balanced road map of sustainable energy development of Ukraine, which will contain guidelines and criteria for decision-making by stakeholders to minimize energy efficiency gaps which will contribute to the country's energy breakthrough in the context of global development trends.Item Biogas as an alternative energy resource for Ukrainian companies: EU experience(LLC “Consulting Publishing Company “Business Perspectives”, 2018) Yevdokymov, Yu.; Чигрин, Олена Юріївна; Чигрин, Елена Юрьевна; Chygryn, Olena Yuriivna; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Люльов, Олексій Валентинович; Люлев, Алексей Валентинович; Liulov, Oleksii ValentynovychThe paper deals with analysis of the preconditions of alternative energy market development in Ukraine. In this case study, the authors analyzed the EU experience. The results of analysis showed that the leader of the EU countries in renewable energy has already achieved the target (20%), which had been indicated. In addition, the findings showed that the share of renewable energy in gross final energy consumption has been increasing from year to year. The authors allocate that, according to the Ukrainian potential, biogas is the most perspective one among alternative resources. Moreover, results of analysis showed that Ukraine has the huge potential of agricultural sector. In this direction, the authors allocated the main types of the agricultural activities, which have the highest potential of biogas production: sugar factories, corn silage and poultry farms. The authors underlined that biogas spreading is restrained by the stereotypes that green investments are not attractive for investors. In order to analyze the economic efficiency of investments to the biogas installation, the authors calculated the profit from the biogas installation for poultry farm. The authors made two scenarios for calculation. The first – the whole volume of energy, which was generated from the biogas unit, will be sold with feed-in tariff. The second – the farm covers its own needs in electricity, the rest will be sold with feed-in tariff. The findings showed that the first scenario is more attractive. Moreover, the farm could receive higher profit if it installed the biogas in 2016, not in 2017. In addition, based on the EU experience and features of farm functioning, the authors approved that the biogas installation has not only the economic effect (profit and additional profit) for company, but also ecological and social effects for rural area, where this farm was located.Item Green competitiveness: Ukraine's business sector in the worldwide trends framework(Тернопільський національний технічний університет імені Івана Пулюя, 2020) Чигрин, Олена Юріївна; Чигрин, Елена Юрьевна; Chygryn, Olena Yuriivna; Люльов, Олексій Валентинович; Люлев, Алексей Валентинович; Liulov, Oleksii Valentynovych; Пімоненко, Тетяна Володимирівна; Пимоненко, Татьяна Владимировна; Pimonenko, Tetiana Volodymyrivna; Kostornova, S.The paper deals with the analysis of measurement approaches for stable competitiveness. The authors substantiate that promotion the stable competitiveness requires the creation of modern theoretical approaches for its measurement and understanding the relevant trends in the national business sector. The analysis results prove that green competitiveness is the part of national economy competitiveness and modern trends indicate that the European countries create new market opportunities for green growth promotion and ecological competitiveness increase. The objective of the paper is to investigate the measurement system for the global stable competitiveness and to analyze the Ukraine internal peculiarities in comparison with the post-Soviet and European countries. The analysis results prove that today’s worldwide trends and tendencies of the countries green competitiveness measurement are described in the approach implemented by the Global Stable Competitiveness Index. The given methodology includes three basic aspects of stable development: economy, environment and society and defines the investigated areas within the framework of five basic fields: natural capital; social capital; resource management; intellectual capital and innovations; managerial efficiency. TOP-20 countries representation according to the Global Stable Competitiveness Index is considered, the leading developed high-income countries are determined and analyzed in this investigation. Ukraine’s position among the European and Post-Soviet countries is shown in this papers. It ranks the 74th place among 180 countries and its score level is 44.7. The authors estimate the prospects for the Ukraine stable competitiveness increase within the framework of its five main determinants.
