Abstract
The article substantiates the expediency of forming hybrid microgrids that can be integrated into a centralized power supply system or operate autonomously in order to expand the use of renewable energy sources and prevent their possible negative impact on electrical network modes. A two-level approach to managing the operation of a hybrid microgrid is proposed, which involves a preliminary planning stage based on forecasted loads, output power of renewable generation sources, market price of electric energy, and a stage of operational control based on data obtained in real time. A number of objective functions and constraints are proposed to solve the task of optimal planning of the operation of a hybrid microgrid as a multicriteria problem. At the same time, the possibility of transforming this problem into a monocriteria one is substantiated. An analysis of the advantages and disadvantages of each of the proposed approaches was carried out. Ref. 12.
