Project Team CapabilitiesORNL Team has key domain experts from industry, academia, and otherNational Labs needed to advance the R&D of the future electric grid.TEAM CAPABILITIESORNL, UTK, and Industry Partners Smart inverter (SI) controls (>7 yrs) expertiseadvancing in self-healing microgrids (MGs). Power systems, protection, power electronicsand control expertise. Chair task force on volt/var control with highpenetration renewables. Member of IEEE PES WG in smart distributionand DER integration Support SI standards development (SCC21,1547, NIST, and EPRI). DECC Lab provides “in-the field” SI and MGtesting with actual distribution system. SPIDERS leveraging ORNL inverter controlsexpertise for military MGs. ORNL partnership with UTK’s DOE/NSFsponsored CURENT center. Industry team (TVA, EPRI, SCE, TVPPA,LCUB, …) provides technical input andguidance Inverter companies provide technical supportand materials. December 200812
Funding LeverageORNL plays a unique role in both providing innovative SI and MG development(controls, communications & protection) and a testing platform on an actualdistribution ib ti system.December 200813These figures above do not reflect the leverage value of a PV inverter, an automobile batteryassembly , and MG equipment to be provided by industry.
