Background

• Operational Energy Advisors/Trainers (REF/E2E)

• Barbaricum deployed over 200 systems 2011-2015

• Middle East, Africa

3

Background

• Modular hybrid systems

• Systems configured on-site

• Extensive data was collected

4

Define

• Hybrid Power System:

• Combination of energy sources

• Generator operation only when needed

• Generator provides “Power surety”

5

Problem

• Hybrid systems relatively new technology

• What can it power?

• How much benefit comes from PV?

6

Challenge

• Hybrid power systems have a large design space

• More solar input = less fuel consumption

• More energy storage = higher energy capture potential

• Is there a sweet spot?

• Fuel minimization?

• Cost minimization?

• Cube, weight and/or foot print minimization?

• How to perform tradeoffs in a tactical environment

7

An expeditionary hybrid sizing tool is needed

Hybrid Tool Development

• Objectives

• Visually based

• Learning Tool

• Enables end user

• Low complexity

• Minimal training required

• Value added

• Highly mobile

• Tailored for 3kW – 10kW Hybrid Systems

8

Promote adoption of hybrid systems

Assumptions

• Law of averages

• All available solar (PV) energy is harvested

• Platform loads are sufficiently random

• Standard component efficiencies

• AC pass through power

What Tool Illustrates

• Largest gains are when generator is underutilized

• Hybrid system makes sense when gen. < 50% cap.

• Large gains come from generator/battery configuration

• Solar (PV) benefits may not out weigh

size/weight/cost/complexity

• System component efficiency has significant impact

• Lead Acid (LA) vs Lithium Ion (Li)

• Power conversion losses

• Can be used for “Right Sizing” hybrid systems

• Correctly match hybrid system with platform load

• Shows diminishing returns

16

Applications

• Training Tool

• Shows hybrid system potential benefits

• Low cost

• Mission Planning Tool

• Cost/Weight/Size tradeoffs

• Enables Warfighter

• Decision Makers

• ROM monetary ROI

• Cost tradeoffs

17

Next Steps

• Identify interested end users

• Create hybrid performance charts for specific systems

• Package tool in a smart phone app or browser

• Link atmospheric database

• Database expansion

• Develop platform load and hybrid system databases
