中國儲能網訊：美國國防部日前發(fā)出招標邀請，要求為其軍事設施的多個項目提供微電網大規(guī)模儲能部署的前期提案，其申請截止時間為3月8日下午2點。
美國海軍陸戰(zhàn)隊空中地面作戰(zhàn)中心擁有10兆瓦的軍事微電網
在闡述微電網技術推廣的理由時，美國國防部門指出，美國主要的停電事件在數(shù)量和嚴重程度上都在增加。此外，軍事基地也經常遭遇中斷事件，并且中斷的時間更長。
“人們越來越擔心，軍事基地是否可以在持續(xù)數(shù)天或數(shù)周的電力中斷期間保持關鍵功能，而不是短短的幾個小時。美國國防部正在積極尋求微電網儲能部署，以保障能源安全，提供更長時間的后備電源?！闭袠送ǜ嫔险f。
美國國防部門正在關注提高能源安全的創(chuàng)新，并計劃對微電網有無采用儲能部署的成本方面進行比較。
該計劃將通過以下方面來衡量儲能性能：
?覆蓋范圍：提供備用電源的容量
?可用性：可用的覆蓋范圍每年的小時數(shù)
?可靠性：獨立備份的可靠性級別（N + 1，N + 2 ...）
?持續(xù)時間：可以保持連續(xù)供電的小時數(shù)
?脫網運轉能力：能夠為負載提供具有適當電能質量的不間斷電源
?堆疊價值：獲得收益和節(jié)省成本，以及與微電網的投資成本和運營成本相關的成本組合
美國國防部將評估其20年的凈生命周期成本，并考慮到微電網儲能部署的安裝、維護、更換、電費和市場收入。微電網儲能部署將與采用太陽能的基準柴油發(fā)電機（見下圖）進行比較。基準微電網將依靠一套2000千瓦的柴油發(fā)電機組提供電能。每臺發(fā)電機的熱耗值為10,618 BTU / kWh。
這個項目將分兩個階段執(zhí)行。
第一階段將涉及各個氣候區(qū)域和能源市場中微電網的設計和建模。美國軍方預計2018年夏季開始進行第一階段工作，并將于2019年3月完成。
第二階段需要進行技術論證和驗證。美國國防部將選擇一些模擬系統(tǒng)的子集，在少數(shù)軍事設施中展示具有發(fā)展前途的技術。第二階段提案的申請將于2019年春季發(fā)布。
目前，美國國防部的環(huán)境安全技術認證計劃（ESTCP）只尋求第一階段的預先提案。（中國儲能網獨家編譯，轉載請注明來源）
U.S. Military Issues Solicitation for Microgrids with Energy Storage
January 10, 2018 By Elisa Wood Leave a Comment
The U.S. Department of Defense (DoD) issued a solicitation Tuesday seeking pre-proposals for multiple projects at military installations that will assess large-scale energy storage within microgrids.

Applications are due March 8 by 2 p.m. ET.
In describing its reason for pursuing microgrid technology, the defense department noted that major power outages are growing in number and severity in the United States. In addition, military bases are experiencing outages more often, and those outages last longer.
“There is growing concern whether military bases can maintain critical functions during outages that last for days or weeks, as opposed to hours. DoD is actively pursuing the deployment of microgrid technologies to provide improved energy security for longer durations,” says the solicitation.
The defense department is focusing on innovations that improve energy security. It plans to compare the cost of achieving energy security with or without energy storage within a microgrid.
The program will measure energy storage performance in terms of:
?Coverage: Kilowatts of backup power provided
?Availability: Number of hours per year for which coverage is available
?Reliability: Level of independent backups for reliability (N+1, N+2…)
?Duration: The number of consecutive hours that coverage can be maintained
?Ride-through capability: The fraction of load for which uninterrupted power with appropriate power quality can be provided
?Stacked-value: The combination of revenue and savings and any avoided costs associated with the capital and operations cost of the microgrid
The defense department will assess cost over a 20-year net life-cycle period, with consideration given to installation, maintenance, replacement, electricity bills, and market participation revenues. The energy storage microgrid will be compared to a baseline diesel generator (see graphic below) with solar added. The baseline microgrid will rely on a set of 2,000 kW diesel generators. Each generator will have a heat rate of 10,618 BTU/kWh.
Projects will be executed in two phases.
The first phase will involve design and modeling of the microgrids in various climate zones and energy markets. The military anticipates Phase 1 work beginning next summer and being completed by March 2019.
The second phase requires technology demonstration and validation. Defense will select a subset of modeled systems to demonstrate promising technology at a few military installations. A request for Phase II proposals will go out in spring of 2019.
Currently, the Environmental Security Technology Certification Program (ESTCP) is seeking pre-proposals for Phase I only.
An an online seminar, “ESTCP Funding Opportunities – FY 2019,” will be offered on January 18 from 1:30 – 2:30 p.m. ET. During the online seminar, participants will have the opportunity to ask questions about the funding process, the current ESTCP solicitation, and the proposal submission process.
