Over the last century, power has been delivered from large, centralized power sources to customers, requiring only a one-way power flow. Today, the grid is evolving to deliver power from alternative sources, including solar panels on rooftops or customer-owned battery storage. This requires a power grid that supports two-way power flow.
Our Distributed Asset Research Testing (DART Facility) is designed to assist the industry in developing and testing DERs and energy management systems. The facility serves as a testbed for performance and reliability testing of DERs, support standards development, and investigate other emerging, complex system integration issues. The DART Facility is connected to the electric distribution system at 12.47kV with a 208 V transformer to power the building.
The facility can operate in parallel to the grid or can operate in island, providing high levels of electrical reliability. The system can disconnect from the utility during large events (i.e., faults, voltage collapses), but has the capability to disconnect intentionally when the quality of power from the grid falls below certain standards.
