The paper analyzes the peculiarities of the development of the energy sector in Ukraine, as well as in European countries. Existing approaches to energy production are shown. The situation in Ukraine has changed in recent years. Energy production has shifted from centralized to distributed. The emergence of new types of power plants has made it possible to connect to the grid in places where it was previously impossible, a large number of consumers already have their own power units. Therefore, managing the energy network is becoming increasingly complex and therefore requires new approaches. The normative and legislative beginning of the active development of alternative energy in Ukraine already exists, and European and world experience should help Ukraine achieve energy independence and high environmental standards. Existing problems in the development of power grids arise due to the intensive growth of production and consumption of electricity, while the management of power systems is complicated by the growing share of distributed and renewable energy sources with changing production schedule. Improved controllability of electrical networks allows to prevent emergencies by load control programs, division of the network into autonomous zones, etc. Investment is a crucial factor in creating a flexible and efficient power grid based on innovative technical solutions. Implementation of energy efficiency projects is a guideline for improving the intelligent level of the energy system, which will allow energy companies to manage the energy network as a single system, increase profitability, reliability and uninterrupted, reduce technical and commercial losses, improve network management and efficiency. An important role is played by the interaction of all stakeholders in projects - the state, production, energy and energy sales companies, consumers and equipment manufacturers. Thus, the international experience in the transmission and distribution of electricity creates opportunities for successfully implementing projects for the introduction of energy-efficient technologies in our Ukraine.
