Microgrid Control and Protection Solutions
Seamless Transitions Between Grid and Islanded Operation
SEL Engineering Services engineers are experts at microgrid design, specializing in power system dynamics, hardware-in-the-loop (HIL) modeling, controls, and protection. With SEL microgrid systems, you can operate an independent power system that prevents blackouts, optimizes distributed energy resource (DER) operational costs, and protects people from injury and equipment from damage during short-circuit events.
Our point of common coupling (PCC) control methods provide a seamless transition to islanding and automatic resynchronization. Subcycle, inertial-compensated powerMAX Power Management and Control System algorithms prevent blackouts when closely timed events occur. In addition, software-defined networking (SDN) ensures best-in-class security for your operational technology networks.
We offer a secure supply chain and the best quality and warranty in the industry. Our power system protection, control, monitoring, metering, and cybersecurity electronics are designed, manufactured, and tested in the U.S.A.
Because of the SEL microgrid controller’s exceptional reliability, security, and performance, National Renewable Energy Laboratory (NREL) in Golden Colorado recently chose it for their Energy Systems Integration Facility.
