Abstract
The paper is devoted to the analysis of frequency requirements regulated by the national and international standards for distribution networks and microgrids. These requirements cover the permissible frequency range and the operation time of the installations, the rate of change of frequency, ensuring the generation of active power by generating units at reduced frequency, as well as the active power control considering increasing or decreasing frequency in the network. Based on the results of the research, the conclusions have been formulated, which are the basis for the development of microgrid models and to verify their compliance with the frequency requirements regulated by the relevant standards.
