Abstract: The present disclosure provides a method for maintaining continuous power to a critical load. The method comprises providing a source side converter (SSC) configured to provide autonomous grid support including reactive power support during fault conditions and a load side converter (LSC) configured to support the critical load by boosting voltage at load terminals through autonomous injection of reactive current, each coupled to a DC energy storage. The method includes coupling the SSC to an AC source and coupling the LSC to the critical load. The AC source and the critical load are connected via a bypass connection including a ride-through inductor with measurement capability. Under nominal source conditions, the SSC and the LSC are controlled so that a majority of power consumed by the critical load flows through the bypass connection.

Abstract: An agile grid forming control system for power electronics converters integrates a dual-time scale control strategy to provide grid-forming operation while compensating for extreme power demand variations. A high-speed digital processor collects real-time electrical measurements at a point of interconnection and dynamically adjusts power output to stabilize grid conditions. The system is particularly suited for AI data centers, microgrids, and other applications with high-variability loads. The system enhances grid stability, enables efficient energy storage integration, and reduces reliance on bulk grid infrastructure.
