Annotation: The article discusses the design of microgrids that use renewable energy sources and energy storage systems as a controlled local power system that operates in both grid-connected and island mode. The goal is to present an integrated approach that combines the choice of architectural design (AC/DC/hybrid), the selection of distributed energy resources (DER) and energy storage systems (ESS), and management requirements (power quality control, energy management system) within the framework of the IEEE 1547 and 2030 standards. Key methods for modeling and optimization, such as multicriteria and stochastic optimization, are described, as well as the main challenges to implementation, such as variability in generation, cyber resilience, and costs. Examples of successful projects demonstrate improvements in reliability, flexibility, and economic efficiency for local power systems.
