Microgrids
With a microgrid controlled by an SEL powerMAX control system, you can operate an independent power system that mitigates blackouts, optimizes operational costs, and protects people and equipment during short-circuit events.
The Microgrid Control System Leaders
Independent third-party evaluations—and performance in installations around the world—verify that SEL powerMAX microgrid systems lead the industry in ensuring stability and optimizing performance under a wide variety of operating requirements.
Integration With ADMS/DERMS
See how SEL powerMAX microgrid control systems integrate with a distributed energy resource management system (DERMS) and advanced distribution management system (ADMS) to help optimize the operational state of the wider distribution grid.
SEL powerMAX Microgrid Control Systems
SEL powerMAX microgrid control systems keep the lights on, seamlessly islanding onsite generation sources and reconnecting with the bulk electric system as needed.
At the Top of the Leaderboard
SEL is the top vendor of microgrid control systems in the Guidehouse Insights 2021 microgrid controls leaderboard report, which evaluates the strengths of the world’s 16 leading microgrid control system providers.
The Guidehouse Insights leaderboard report evaluates microgrid control vendors on 12 metrics—including islanding ability, controls functionality, pricing, geographic reach, and market staying power—to arrive at composite scores for strategy and execution.
Navigant Research (now Guidehouse Insights) also recognized SEL as the industry leader in its 2018 leaderboard report.
Winning Performance
In 2017, SEL powerMAX was recognized as the top-performing control system at a microgrid symposium hosted by the Massachusetts Clean Energy Center and the MIT Lincoln Laboratory.
Later that year, a powerMAX microgrid control system won a rigorous, 21-week procurement competition held by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
SEL outperformed the competition by achieving economical operation and superior stability under a wide array of difficult operating conditions. A powerMAX microgrid control system is now installed at the NREL Energy Systems Integration Facility, where it is used to test emerging microgrid technologies.
SEL Microgrid Controller Wins NREL Competition
The National Renewable Energy Laboratory (NREL) invited five teams to compete in a two-part, 21-week microgrid controller competition.
Engineering for Reliability
SEL leverages the time-proven strengths of relay-based protection and control architecture, powerful automation controllers, and our products’ unmatched reliability to create resilient microgrid control systems. By designing for reliability first, we reduce operating costs, improve system performance, and deliver an unbeatable lifetime return on investment for our customers.
Configuring a reliable microgrid control system goes beyond merely selecting the right components. Microgrid control systems pose a difficult and unique set of engineering challenges, and each control system must be custom-engineered for its specific implementation.
Our power system engineers work closely with microgrid owners and integrators to design, engineer, and implement the best possible microgrid control solution for your operational requirements.
Every microgrid project includes four steps that ensure the success of your SEL-engineered solution.
- Define System Requirements
A front-end engineering design (FEED) study establishes and defines technical requirements, applicable standards, and project guidelines. We draw on our field-proven success with microgrid projects and decades of experience as a trusted utilities solution provider to develop a plan that prevents unexpected changes, reduces risk, and ensures efficient execution of the project. - Evaluate System Performance
We use our expertise in system modeling and studies to perform detailed simulations, which help microgrid owners make key decisions about the project. These studies and simulations can be used to plan a new microgrid, evaluate and improve an existing microgrid, or investigate a specific system vulnerability. - Perform Hardware-in-the-Loop (HIL) Testing
SEL microgrid control systems that connect to the utility grid are tested in our state-of-the-art Real Time Digital Simulator (RTDS) lab. We put the actual SEL hardware that will run the system through an intense battery of tests to verify that the whole system performs as expected. This also helps us commission your microgrid quickly and smoothly. - Transfer Knowledge
Comprehensive training is part of the implementation process. We provide a complete set of materials and documentation along with onsite personnel training and advanced engineering training for ongoing system and configuration management. Advanced engineering training is also available. In addition, you have access to free technical support for the life of your SEL solution.
