Recently, the traditional energy system cannot satisfy the needs of a large number of users, therefore, to ensure efficient use of energy, it is necessary to apply new structures and technologies. Today, the key problem of the Russian energy community is low energy efficiency, which, in turn, has a negative impact on the country's economy. Innovative transformations can play a major role in improving energy efficiency. The introduction of methods and technologies of predictive analytics allows for the most efficient reengineering of production processes and the highest quality prioritization in the development and implementation of innovative products. The integration of intelligent network technologies, sustainable energy resources is an important path to sustainable development. To increase the share of import substitution, and in the long term to start exporting the developed technologies and ready-made technical solutions, support and development of the innovation environment and existing promising projects both from the state and infrastructure organizations, as well as from market participants are necessary. A number of areas of innovative transformations in the electric power industry have been identified, which in the near future will determine promising technological and market trends. When creating effective innovative projects, it is important to choose the right approach used in innovative design. In addition, in the current market conditions, the efficiency of the energy industry directly reflects the effectiveness of the adopted and implemented innovative solutions. Being one of the most important factors in the socio-economic development of any state, the state of the energy complex and its relationship with other sectors of the national economy determines its significant impact on the sustainable innovative development of Russia.

In the global energy system, the fight against climate change, meeting the growing demand for electricity, using the opportunities gained through the fourth industrial revolution and affecting all sectors of the economy and the related qualitative changes in the characteristics of electricity demand become extremely urgent. In recent years, the general pace of innovation has been growing, while introducing innovation in the energy sector has become a complex long-term challenge. Digitalization of the electric power industry in Russia is one of the key objectives of the industry development. The purpose of this study is to consider the existing classification of innovations from the standpoint of the electric power industry and to determine what qualitative and quantitative effects the introduction of innovations in the Russian electric power industry gives. To calculate the effects, we used data from Federal State Statistics Service and the Russian Energy Agency, as well as annual public reports of the System Operator and data provided by NP «Market Council». An assessment is made based on optimistic and pessimistic scenarios. As the first, the highest values were taken, as the second – the lowest values according to experts' forecasts. First proposed classification of types of innovations in the electric power industry related to changes in technology and changes in the market. The effects of each type of innovation are also calculated. The paper concludes that the effects of innovations due to changes in technology are more influential than innovations due to changes in the market.

The main task of Ukraine's energy strategy until 2030 is to bring the country's electricity complex in line with international requirements for efficiency and reliability of energy supply, which requires improvement of the regulatory framework of Ukraine's electricity. The introduction of international standards as national standards of Ukraine will remove many controversial issues in the modernization of energy facilities, promote domestic energy equipment in the Western market, create conditions for parallel operation of Ukraine's energy system with European energy associations, improve the quality of energy. But updating the regulatory framework of the industry requires significant time and money, so it is necessary to properly organize this process in order to improve the technical and economic efficiency (EE) of energy in the shortest possible time with minimal costs. One of the methods of solving this problem is complex standardization (CS), the methodological foundations of which were laid in Soviet times, but are outdated due to changing economic conditions and basic criteria for assessing the efficiency of energy facilities, especially their impact on humans and the environment. Therefore, it is necessary to develop a new approach to the COP in the field of electricity in modern conditions, in particular, to develop a model of the COP, methods, classification of tasks and determine the priority of standardization in the field of electricity. Standardization in the electricity sector should cover all major areas of industry development and contribute to the creation of conditions for safe operation of electricity facilities, ensuring rational energy consumption, improving the technical level and environmental safety of energy facilities, ensuring reliable and efficient operation of Ukraine's integrated energy system. Therefore, the development of the COP model should be based on the structural model of the power industry, which corresponds to the real conditions of the industry. To ensure the cost-effectiveness of the COP, it is necessary to develop a new methodology for evaluating EE development and implementation of standards for energy equipment in market conditions, as well as methodological approaches to economic optimization of the sequence of implementation of standards. Thus, the development of scientific and methodological principles for improving the system of regulatory documents of the electric power industry of Ukraine is an urgent and important task, the solution of which will contribute to the effective updating of the regulatory framework of the industry.

Currently the issues of reliability and efficiency assessment of the operation and dispatch control of the Unified Energy System of Russia remain unreported and require the attention of the scientific community, electric power industry stakeholders, as well as federal and regional regulatory bodies. The paper studies the structure, mechanisms of interaction between the operational dispatch control participants and the electric power industry, regulatory legal acts, as well as the practice of operational dispatch control of the Unified Energy System of Russia and the electric power industry of foreign states. The existing system for assessing the reliability and efficiency of the operation and dispatch control of the Unified Energy System of Russia is considered. The study employs such methods as analysis, synthesis, generalization, abstraction, comparative and logical methods. The paper highlights the impossibility of unambiguous perception by all subjects of the electric power industry as a justification for technical solutions, argumentation of their own actions and in other business processes, justification of the position of ensuring reliability, due to the absence of a clearly developed regulatory framework in the field of reliability (generally accepted apparatus and terminological certainty). The paper substantiates the need for monitoring and assessing the reliability and efficiency of operational dispatch control in the electric power industry. The problems of monitoring and evaluating operational dispatch control in the electric power industry are considered. The practical result of the work is suggested drafted organizational structure for monitoring the reliability and efficiency of operational dispatch control in the power industry.
