The positive experience of using various technologies in power systems as consumers-regulators for energy management is shown, which helps to increase the reliability and stability of power systems, and also reduces the need for new generating capacities, including expensive peak ones. The world experience of legal support for the use of consumers-regulators in power systems at the international, national, and regional levels is considered, namely: directives and regulations of the 4th European EU Energy Package; laws of the USA about independence and national security, energy efficiency improvements, research and development for grid modernization, and the results of the programs developed based on them; laws and regulations of the U.S.A. states and Canada to promote energy savings and reduce greenhouse gas emissions through increased use of renewable energy sources (RES) and other new technologies; the effectiveness of the system of measures DSM (Demand Side Management). In these documents, an important role is assigned to both the use of technologies such as RES, energy storage, Smart Grid, etc., and the possibility to combine consumers of different categories and the rules for their participation in the electricity market in a non-discriminatory way. An increase step by step in support for the use of consumers-regulators in power systems in the legislative and other national documents of Ukraine, in particular, in the new law on the development of energy storage installations, the National Action Plan for Renewable Energy for the period up to 2030, the National Transport Strategy of Ukraine for the period up to 2030, etc., which meet the main provisions of European directives, and it is also shown the need to take into account the wide introduction of new technologies such as Smart Grid, building consumption regulation, the use of electric vehicle charging stations, etc. Keywords: consumers-regulators, legal support, power system.
