Renewable-first operation
Use available renewable generation to serve loads and charge storage before higher-cost sources, where suitable.
System architecture
Power path and control logic
A modular reference architecture adaptable to distributed energy, off-grid, weak-grid and hybrid applications.
Reference architecture
Sources → PCS / conversion → distribution → loads
EMS and the microgrid controller communicate with sources, interfaces and loads to coordinate operation.
Conceptual system architecture. Final topology, protection, switching, equipment selection and compliance requirements are subject to project-specific engineering assessment.
The EMS coordinates and controls operation. Primary electrical power flows through the power conversion and distribution architecture.
Design principles
AC-coupled, DC-coupled and hybrid options
Depending on the project, NUSLUME may assess AC-coupled, DC-coupled or mixed architectures. Selection depends on existing assets, PV topology, storage requirements, islanding objectives, efficiency, redundancy, protection and the capabilities of the selected PCS / hybrid inverter platform.
Applied project by project
Battery reserve management
Maintain project-defined SOC windows for resilience, generator coordination or planned island operation.
Source coordination
Coordinate PV, BESS, grid and genset using thresholds, schedules, priorities and project constraints.
Critical-load segmentation
Separate essential and flexible loads to preserve critical operation during constrained supply.
