“Doing for Electricity what the Internet did for

Information”

Brian T. PattersonPresident – EMerge Alliance

The EMerge Alliance is the world's largest professional organization dedicated to advancing standards for direct current technology. It is an open industry association of

collaborating commercial, government and academic organizations developing standards covering hybrid AC/DC microgrids used in commercial and residential

buildings and campuses. EMerge standards facilitate the achievement of greater energy efficiency, safety, resiliency, and sustainability while maximizing the potential

to use of clean, renewable on-site energy.

Involving a greater reliance on the native form of electricity: DIRECT CURRENT in microgrids


Why DC Microgrids?

Key Drivers: • Solar and other renewable sources

• The use of electricity storage

• The local coupling of multiple sources and loads

• Ease of solid-state digital (dc) articulation of power

• Increasing use of electronic loads

• Desire to simplify system electronics

Total Frequency Conversion Points 6 2

Microgrids Require Power Conversions

Notes: •Frequency conversions are generally much less efficient than simple voltage conversions•Conversion efficiency is almost always better at higher voltages and currents•Wire Size favors DC at equivalent voltages


Optimizing Power Conversions Via the Use of DC Microgrids Can Result in Double-Digit

Efficiency Increases

Barriers to Overcome Full Utilization of DC Microgrids

• The Myths:

• Not as safe as AC

• Not good for long distance transmission

• Thicker wires needed?

• It’s not that much more efficient?

• The Reality:

• Standards & codes gaps

• Under-developed supply base

• Insufficient Industry knowledge base

• MEP, contractor & trade training required

• Volume market pricing
