Automated Transit Fleet Electrification Planning in Response to Route Dynamics, Vehicle Utilization, and Local Climate
Transit electrification is difficult, requiring the consideration of many factors including route dynamics, vehicle utilization, and local ambient temperatures. Incumbent planning tools typically rely upon static vehicle efficiency numbers which do not consider local factors speci...

A Techno-Economic Evaluation of Microreactors for Off-Grid and Microgrid Applications
Journal analysis comparing microreactor-based portfolios to diesel and renewable alternatives in off-grid and islanded microgrids. Modeled cases examine levelized cost, reliability, and emissions outcomes across fuel prices, demand profiles, and storage penetration. Findings ident...

Synchronization of Lienard-Type Oscillators in Heterogenous Electrical Networks
Motivated by potential applications for power-electronic converters in microgrids, we study the problem of global asymptotic synchronization of Lienard-type nonlinear oscillators in heterogenous LTI electrical networks with series R-L circuits modeling interconnections. By heterog...

Test of a 250 kVA Battery-Inverter System Micro-Grid: Cooperative Research and Development Final Report, CRADA Number CRD-11-460
Portland General Electric (PGE) is installing a 5-megawatt (MW) lithium-ion-based battery-inverter system (BIS) in Salem, Oregon, as part of the Pacific Northwest Smart Grid Demonstration Project. NREL will assist PGE in testing a 250-kilovolt-ampere (kVA) portion of the BIS in or...

Experimental Characterization Test of a Grid-Forming Inverter for Microgrid Applications
Standardized experimental testing protocols for grid forming (GFM) inverters to ensure expected operation under both normal and contingency conditions do not exist. Such protocols increase the confidence of system owner/operators that an inverter deployed in a proposed system will...

Autonomous Microgrid Restoration Using Grid-Forming Inverters and Smart Circuit Breakers
The proliferation of distributed inverter-based resources (IBRs) raises the questions if these IBRs can be used to blackstart microgrids and distribution feeders after major outages. In this paper, we propose and evaluate an autonomous microgrid restoration concept using grid-for...

Use of Grid-Forming Medium-Voltage Power Electronics Hub in a Microgrid Setting
This paper presents the application of a new design of a multiport, modular, medium-voltage power electronics hub (M3PE-HUB) in a microgrid setting. The M3PE-HUB system was modeled in a digital real-time simulator (DRTS) and integrated into the Banshee microgrid test system. This ...

Development of a Practical Secondary Control for Hardware Microgrids
Practical, vendor-agnostic interoperability guidelines for the secondary control architecture of microgrids (MGs) with multiple grid-forming (GFM) inverter-based resources (IBRs) have not yet been developed. Therefore, this paper proposes a generic and vendor-agnostic secondary co...
