The Schneider Electric meter is well-known for its predominant usage and dependability over decades. It is gaining applause for its super-efficiency and is becoming the customers’ first choice. Duke Energy®, serving 25 million people and businesses (2016), knows first-hand the customer success story of microgrids and Schneider Electric power meters and software.
Microgrids are trending nowadays and don’t you want to know what helps make this new celebrity of the electric industry work? Intelligent power and energy meters, interconnected with the microgrid control network, play a key role in microgrid ality.
Schneider Electric PowerLogic ION8650 series meters provide the monitoring data that’s crucial for operating microgrids.
Just how does Duke Energy know for certain the flexibility and backup security of these meters? And why is Fire Station 34 in Charlotte, NC, grateful?
When the South’s Queen City, as Charlotte is known, endures the grid-threatening temperature of 98 degrees, Fire Station 34 in the McAlpine Creek area stands always ready to respond. That’s because of the microgrid partnership between Duke Energy and the city of Charlotte, relying on Schneider Electric products, chose this fire station for a test microgrid.
“We rely on an uninterrupted power supply to carry out our mission,” said Damian Owens, Charlotte Fire Department Battalion Chief. “We must have power to open and close the bay doors, operate our station alerting system, heat and cool the station, and run fuel pumps for refueling the trucks.” (from Duke Energy Illumination, October 2016)
In Charlotte, the Duke Energy McAlpine Creek Substation has served as a testing ground for smart grid technology and renewable generation. A 50 kW solar installation and a 200 kW/500 Battery Energy Storage System (BESS) are connected in parallel to import and export energy to the circuit at the substation.
PowerLogic ION8650 meters, interconnected with the microgrid control network, provide critical data needed for operation and testing of the microgrid.
Duke Energy used these meters to monitor and assess any power quality events. Moreover, it was also installed to meter the auxiliary power to the microgrid and provided an understanding of the impact of this significant load on the microgrid. Both the ION8650 socket and PM800 panel-mounted meters from Schneider Electric were of great help during the testing process and success of the microgrid.
The ION8650 Series Meters Provided:
In addition, Duke Energy was able to test grid support services while demonstrating the enhanced flexibility and stability of microgrids. The meter’s real-time data in conjunction with Schneider Electric’s PowerLogic ION Setup Software helped to visualize and report the captured waveform disturbances for tracking and analyzing. They now could better understand switching transitions and determine causes of unattended islanding events.
With the ability to operate a successful microgrid in place, Duke Energy can provide a new offer to customers, use them to increase flexibility, and can improve the operation of the smart grid.
Microgrids can help to achieve cost savings by reducing peak power demand and electric generation. It keeps processes and buildings running, while isolated from a damaged grid.
Some of the nation’s most noted microgrid projects can be found at colleges and universities such as Princeton, Harvard, and Wesleyan University, which were early adopters of the technology. Also turning to microgrids are the military, commercial and industry, and communities.
They are learning first-hand the benefits of microgrids:
Or, in the case of Fire Station No. 34 in Charlotte, being able and ready to answer the 911 calls during an ice storm or the summer heat.
