FEATURES OF THE FUNCTIONING OF SMALL POWER SOLAR GENERATION IN THE IPS OF UKRAINE UNDER THE CONDITIONS OF THE GREEN TRANSFORMATION

Abstract

Within the framework of the transformation of the energy system in terms of ensuring the further development of small distributed generation from renewable energy sources, a new support model for low-power facilities is proposed, which will facilitate the commissioning of new generation entities. In the paper, research is conducted on the problem of small generation in Ukraine, which is faced by the power system, in the conditions of an increase in the share of distributed generation. An assessment of the impact of small solar power plants on the operation of the electrical network, including rooftop ones installed in households, was carried out. Typical schemes of connection of SPPs to the electrical network are considered and their influence on electrical equipment, elements of power supply systems and principles of operation are determined. It has been established that the integration of new renewable energy entities, including low-power SPPs, causes a number of technical problems that have an impact on the operational characteristics of the network, security of supply, and reliability. The main ways of solving the problems of losses and deviations of the voltage level in distribution networks, when connecting small SPPs, have been formed. In further research, the obtained results will be used to develop proposals for connecting low-power entities to the electric network and their formalization in the form of provisions of regulatory and technical documents.
