SEL Microgrid Control Systems

SEL's microgrid control systems (MGCS) are an efficient, reliable, and secure solution for guaranteeing uninterrupted energy delivery to your facility and customers. They control and protect both renewable and conventional generation. SEL systems allow you to operate independently, ensuring a constant supply of energy after loss of utility point of common coupling (PCC). SEL's MGCS also let you manage energy storage to maximize renewable generation and reduce peak charges.



Stable and Reliable System Operation

  • All control systems are validated with real-time electromagnetic transients program (EMTP) simulation.
  • Subcycle control using a fast, deterministic microgrid controller reliably integrates renewable generation and battery storage.

Eliminate System Blackouts

  • Quickly detect grid disturbances and open PCC with the utility.
  • Ensure uninterrupted power to mission-critical loads.



Safe Operation

  • Advanced protective relays with adaptive protection settings ensure your equipment and system are protected
  • High-resolution metering and fast control maintain high power quality throughout the system

Reduce Energy Costs and Emissions

  • Economic and environmental-based generation control optimizes available resources
  • Support for utility grid (VAR flow, demand response, etc.) maximizes return on investment
