Secure Network of Assured Power Enclaves: Fort Bragg SNAPE IDG (registered trademark) Microgrid System
Abstract
SNAPE (Secure Network of Assured Power Enclaves), at Fort Bragg is a new approach to microgrid design wherein smaller microgrid enclaves cooperate to provide energy reliability and stability for a larger virtual microgrid. Novel controls design to be demonstrated on a full-scale installation. The SNAPE builds on existing technologies to establish microgrid enclaves that operate independently with local controls, but also cooperate automatically during outages to improve power stability, availability, and efficiency. The microgrid utilizes an existing 5.65 MW CoGen at the Central (CoGen) Plant and two 625 kW generators provide power to Circuit 1 (CKT 1) and Circuit 5 (CKT 5) during such utility outages. A new cyber security strategy that segregates communication networks needed for fast, real-time control for synchronization and stability from those used for external control signals and monitoring. Grid frequency and load sharing set within each enclave through active controls, but load sharing between interconnected enclaves will be through droop control.
