Vakulenko I. Organizational and economic principles of smart grid implementation in the energy sector of Ukraine

The thesis examines the development of economic and organizational principles for implementing the smart grid to form an integrated energy-centric model of Ukraine's economy following the European Union's single energy policy. Accordingly, using VOSviewer v.1.6.10 and Google Trends tools, the author investigated the theoretical foundations of the study of the structural and functional environment of the smart grids concept formation and development. It allowed us to identify and describe patterns in the following dimensions: еvolutionary, geographical, semantic. The research also revealed trends in changing the direction of smart grids' economic analysis from approaches to tariff formation and commercialization of smart grids to study smart grids' global economic model and their technical and economic efficiency energy consumption patterns. The thesis proposed a scientific and methodological approach to assessing the impact of smart grids' policy on country's socio-economic development. It was done through a systematic combination of tools to verify the nature of data distribution, equality of sample variances, comparison of their means, and regression analysis of time data. A methodological basis for a comparative analysis of existing systems for evaluating smart grids' efficiency was formed. The approach was based on identifying functionally significant components of smart grids and the most relevant of them under the objectives of the energy sector of the national economy. These components are sustainability, information, economic, technical, communicative efficiency, environmental friendliness, and electric transport infrastructure in smart grids. It allowed to evaluating and ranking the existing systems for measuring the efficiency of smart grids in state regulation of the economy's energy sector under the standard EU energy policy requirements. The integrated approach to smart grids` efficiency evaluation was developed. The proposed method takes into account the purpose of the assessment. It allowed for a more accurate evaluation of potential or existing smart grids and measured smart grids development's effectiveness at the regional and national levels. Establishing the optimal number of areas for assessing smart grids, formalization of the methodological basis for their quantification, aggregation of indicators by groups and areas of assessment, taking into account direct and indirect effects, opportunities for further optimization of smart grids, and ensuring their compliance with the strategic task of building an integrated energy centered model in Ukraine was presented as a component of the integrated evaluation approach. Designed roadmap for developing smart grids in Ukraine is based on benchmarking analysis of leading countries' experience. An organizational and communication scheme of stakeholder interaction is a tool to activate drivers for smart grids. It helps to implement energy-efficient smart grid projects and support their scaling to the national economy level.
