The SISGSR (Storage Integrated Smart Grid Stability and Reliability) is an AI-based FIU Renewable Smart Microgrid research platform. The key concept of the project is to ensure reliability, efficiency, security, and sustainability. The operational facility includes a grid-tied 3 MW/9 MWh lithium-ion battery energy storage system integrated with FIU’s 1.4 MW FPL-FIU solar array. Solar generation can charge the battery and support the Engineering Center’s critical loads. The microgrid can operate in both grid-connected and island modes and uses a black-start-enabled grid-forming inverter to support independent operation during outages and adverse grid events. EPSi researchers use the platform to develop and test AI-based control systems under operational conditions to improve energy-storage efficiency, reliability, resilience, and economic viability. The following figure illustrates a representative battery energy storage system.

The SISGSR platform also supports research related to contested logistics, where access to conventional power infrastructure, fuel, and maintenance resources may be limited or disrupted. Its flexible architecture can enable the rapid deployment of an ad hoc microgrid to supply resilient power to critical facilities and mission-essential loads.
