DoD Energy Test Bed Demonstration Projects on Military Installations

摘要

1. Diesel generator provided power to critical loads 2. PV was unavailable 3. 250kW Load Bank used to test diesel generator; energy dissipated as heat. 1. Baseline Peak Demand = 305kW. 2. Microgrid Peak Demand = 261 kW (14.4% reduction). 3. Use of PV array in microgrid mode reduced diesel fuel consumption and GHG by over 20%. 4. Microgrid maintained critical load of 30-50kW (80kW peak) 5. Stable voltage, frequency and power factor when islanded. 6. Some issues with transient power when PV dropped rapidly. 7. Microgrid maintained power factor ＞ 0.9 when grid connected. 8. Simulated energy arbitrage, but cycle life of battery a concern. 9. Savings to Investment Ratio ＞ 1.5 when scaled for BCT with 4.5MW peak load (9 year payback using NIST BLCC). 10. Follow-on: Integrate another battery system (EW-201404).
