Invention Reference Number
This technology introduces a method for managing dynamic operational scenarios where multiple microgrids may dynamically extend their operational boundaries to supply unserved customer loads. Unlike today’s fixed-boundary systems, competing microgrids must coordinate coverage without revealing sensitive operational details. The invention provides a controlled decision-making framework that enables microgrid-to-microgrid interaction, supporting fair load coverage allocation while protecting proprietary data.
Description
Modern microgrids operate within defined physical, electrical, and organizational boundaries, which limits the ability to respond flexibly during outages or high-demand periods. As distributed energy systems evolve, multiple independently owned microgrids may need to expand beyond these boundaries to serve unmet loads. Such interactions introduce challenges related to competition, data privacy, and operational transparency.
This invention presents a coordinated methodology that enables microgrids to evaluate boundary extension opportunities without disclosing sensitive information. Through a controlled optimization and bidding framework—implemented across microgrid controllers and distribution management environments—the system facilitates equitable decisions about which microgrid should serve additional load. The approach considers resource availability, operational constraints, and business relationships while maintaining minimal data exchange among parties.
The methodology has been demonstrated using representative multi-microgrid scenarios featuring renewable and storage resources alongside realistic load profiles. Results show that the framework can differentiate among varying levels of resource sufficiency and consistently determine suitable load-coverage strategies for distinct expansion conditions.
