This study presents a comparative analysis of well-known methods for structuring local microgrids with diverse generation sources, active consumers, and energy storage systems as a prototype of a territorial energy community. The scientific concept disclosed in this publication focuses on justifying the evaluation methods of operating modes of microgrids with polygeneration to determine their stability and energy efficiency boundaries.  Scientific tasks are related to assessment advantages and disadvantages of various methods used for selecting the structure of generating sources and determining demand components to develop optimal scenarios for ensuring the resilience and energy efficiency of such networks. The study compares methods for determining the boundaries of dynamic and static stability in a polygeneration-based microenergy system; management approaches in grid-connected, islanded, and hybrid (considering self-generation) operational modes. Additionally, considered aspects of forming real-time optimal dispatch strategies, and developing market mechanisms for energy community members based on the criterion of minimizing the total cost of electricity supply. Technological efficiency of microenergy system components, economic viability, stability, and reliability were selected as criteria for comparison. The results of the comparative study make it possible to determine optimal approaches for forming the technological structure of a specific energy community, taking into account available local resources, network infrastructure characteristics, seasonal demand fluctuations, and other variables. As the analysis outcome, accents have been made with regards to energy-economic prerequisites for the development of decentralized energy systems with renewable energy sources and combined energy generation installations.  It is established that managing the energy efficiency of microgrids with renewable energy sources and system-level energy storage requires the development of new models for load balancing and demand forecasting, as well as theoretical instruments for defining micro-market relationships among energy community participants, specifically ‒ system-level electricity suppliers, local prosumers with predefined generation conditions, and end consumers.
