• Easily reconfigurable infrastructure for a variety of experiments
• Protocols in place to apply international standards• Ability to assess components (hardware-in-the-loop)
and integrated systems• Ability to work at large scale, to simulate “real-world”
grid-level effects• High level of rigor in data collection, calibration, and
accuracy• Multiple layers of infrastructure: power systems,
Solar Reconfigurable Open Architecture Design (ROAD)
Single-phase Lateral, 12.47 kV
Service transformer
•Replicate high PV penetration at residential scaleReplicate high PV penetration at residential scale•Full flexibility at each nodeFull flexibility at each node
Single-phase lateral is 480 VacThere are two 5-home circuits and each circuit has 4 PV grid tied homes and 1 PV/battery grid tied home.Both circuits have there own Xfmers but can be tied together as shown below. Service transformer is 100kVA 480:240/120 (FYI)

• DETL works with many industry partners interested in global markets
• Advances in power electronics are taking place across the globe – access to latest in new developments
• Greater knowledge/understanding of standards and protocols from other parts of world can facilitate in-country development
• Development and operations of test facilities can benefit from knowledge of testbed innovations in other countries
