SEL powerMAX garrison-scale microgrid control systems are designed for military bases and similar applications where resiliency is paramount.
The powerMAX Power Management and Control System uses hardened computing and communications, including adaptive relaying and cybersecurity, to provide high-performance control and reliability.
Our control algorithms and demand response operate quickly and accurately to preserve the balance between load and generation, maintain system stability and, most importantly, make sure the base is operating at all times.
Unlike many other microgrid control systems, powerMAX is modular and scalable; you can purchase and build your system in blocks over time as funding permits.
Microgrids have low inertia compared to the larger macrogrid. The powerMAX system is ideal because the SEL Real-Time Automation Controller (RTAC) makes automated control decisions at near-relay speeds, allowing the system to maintain the balance between generation and load in response to fast-developing adverse conditions.
If a generator or communications are lost, the system automatically reroutes power. If generation doesn’t meet the load requirements, powerMAX prioritizes loads and minimizes load shedding to maintain power.
For military installations that use backup diesel generation, powerMAX can parallel existing diesel generators. The benefits of paralleling include wet-stacking correction and fuel savings, which increase resiliency and prolong mission capability.
Additionally, the powerMAX control system doesn’t rely on proximity to any given generation source or load; it can be located anywhere within the base, allowing for a more strategic base layout.
SEL’s TMS-MIL-STD-compliant microgrid is unique in that it works with all makes and models of generators, inverters, and loads. You can easily retrofit existing commercial off-the-shelf and tactical microgrid system (TMS) generators in the field with an SEL control system. If a generation device communicates, we can connect, control, and parallel it.
SEL microgrid systems use a defense-in-depth approach to guarantee information assurance and secure operation. We apply cybersecurity in a layered approach that maximizes reliability and minimizes the intrusiveness of controls on existing critical processes.
In addition to physical security, SEL implements four digital zones of defense in our systems.
The cybersecurity structure in SEL microgrid controls ensures resilient power to critical facilities and protects not only against malicious attacks, but also against internal errors, with the ability to control user access to different information throughout the system.
Independent third-party evaluations—and performance in installations around the world—verify the effectiveness and reliability of SEL powerMAX microgrid systems.
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.
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.
