This panel will present the latest tools developed or under development by national labs and research institutes funded by the DOE Sunlamp program and will include topics such as: an overview of the DOE Sunlamp Program; a tool suite for improving grid performance and reliability of combined transmission-distribution with high solar penetration; enabling high penetration of distributed PV through the optimization of sub-transmission voltage regulation; rapid QSTS simulations for high-resolution comprehensive assessment of distributed PV; opportunistic hybrid communications systems for distributed PV coordination; and visualization and analytics of distribution systems with deep penetration of distributed energy resources (VADER).
