Microgrid and battery projects are complicated systems comprised of batteries, inverters or power conversion systems (PCS), transformers, cyber secure communications, metering, switching, energy and battery management systems, microgrid controllers (if applicable) and auxiliary equipment.
SDG&E has been rapidly expanding its battery energy storage and microgrid portfolio. We have around 21 BESS and microgrid sites with 335 megawatts (MW) of utility-owned energy storage and another 49+ MW in development.
Grid-tied microgrids operate all storage and generation assets in parallel as needed, similar to off-grid microgrids. Grid-tied microgrids may include backup-only microgrids, which use a battery energy storage system to power loads, but do not use any other generation assets, such as solar — in this case, Microgrid Controller is not required.
In such off-grid power systems, battery management is best done through the use of a microgrid controller and an energy monitoring platform. Elum Energy provides a wide range of solar products and ePowerControl MC and ePowerControl PPC along with our monitoring platform ePowerMonitor are best suited to perform these tasks effectively.
