Oncor, S &C Electric, and Schneider Electric have unveiled one of the most sophisticated microgrids in North America, near a remote frontier post in Lancaster, Texas.
S &C and Schneider Electric built the microgrid in 6 months at Oncor’s System Operating Services Facility (SOSF).
The new microgrid consists of 4 interconnected microgrids and 9 different distributed generation resources: 2 solar PV arrays, a microturbine, 2 energy storage units (batteries from S & C and Tesla) and 4 generators.
David Chiesa, Director of microgrid business development at S&C notes its uniqueness because the single microgrid is broken down into “four microgrids that can be controlled individually, combined, operated in parallel, in tandem, or independently as one large microgrid.”
All of the components work together autonomously without human intervention, offering a first-of-a-kind automation that could be the future of the distributed grid.
The microgrid can operate at its peak capacity of 900 kW for two hours, and eventually drops to a baseload of 550 kW when solar generation falls off at night and the battery assets drain. However, as long as there is access to fuel, it can operate indefinitely on sunshine and propane-powered generators.
