MDT Purpose
The Microgrid Design Toolkit (MDT) is a decision
support software tool for microgrid designers in the
early stages of the design process.
The software employs powerful search algorithms to
identify and characterize the trade space of alternative
Once the trade space has been characterized, the software provides many
views and features to help explore that trade space to extract information
design decisions in terms of user defined objectives. Common examples of
such objectives are cost, performance, and reliability.
2
Progress
 MDT 1.1 Beta is now available for download from
http://www.energy.gov/oe/services/technology-development/smart-
grid/role-microgrids-helping-advance-nation-s-energy-syst-0
 Has been downloaded more than 400 (unique) times since posting on 4/6/16.
 Several organizations have agreed to review the software
 Port of Los Angeles
 MelRok
 IPERC
 Burns & McDonnell
 MIT Lincoln Labs
 Further development is underway with the US Marine Corps.
Improvements to both the analytics and the user interface are in progress.

Uses
The US Marine Corps Expeditionary
Energy Office (E2O) used the MDT to
assess microgrid power systems and
Mobile Electric Hybrid Power Sources
(MEHPS) for expeditionary units and
brigades.
Over 70 microgrid models were developed in the
MDT and used to provide design support for these
islanded power systems.
The SPIDERS Program used a
predecessor to the MDT to develop the
preliminary microgrid designs for 3 military
bases.
• Joint Base Pearl Harbor–Hickam
• Fort Carson
• Camp Smith
These microgrids are currently in operation on these
installations
The City of Hoboken, NJ used a
predecessor to the MDT to develop the
preliminary microgrid design for backup
power in response to Hurricane Sandy.
The primary goals of this design effort were to mitigate
the impacts of extreme flooding on the distribution
systems and electricity service throughout the city.
Current uses of the MDT include:
• Continued use for the Marine Corps
• A backup power system assessment and Microgrid
Design of the UPS Worldport facility in Louisville,
KY.
• A backup power system assessment and Microgrid
Design of the city of New Orleans, LA.
4
Usage
What would a designer do with the MDT? What are the input requirements?
A designer would input the details of their design problem in terms of:
 Microgrid topology (busses, lines, transformers, generation sources, storage assets,
loads, …). In addition to fixed topology, one can define topological decision points.
Examples could include how big a generator should be, whether or not a battery or
PV system should be included, whether or not redundant connections are needed.
 Design Goals. The MDT has many built-in metrics that can be computed to
determine the quality or “goodness” of a microgrid design. The user can choose
which ones to use. Some examples are Purchase Cost, Energy Availability, Quantity
of Fuel Used.
5
Usage (cont.)
What kinds of questions can the MDT answer?
 Example MDT analysis questions:
 “Should the existing generator on building A be replaced? If so, what type
should the new one be and how big should it be?”
 “Should we build a new building to house additional generation assets and if
so, what generation assets should be used and how and where should the
building be connected to the grid?”
 “Should we install a new redundant backup feeder on our microgrid?”
 “Should we add a PV installation and if so how big? Also, if we add one, should
we also add a battery to support it and if so, how big should it be?”
 “Should we include building X on the other side of the compound in our
microgrid or should it remain isolated with its own backup generation?”
 “We have a new load to include on our installation and may put it in building A,
building B, or building C. Which should we put it in or does it not matter?”
6
Usage (cont.)
The MDT produces a set of solutions that represent efficient trade offs
amongst the design objectives. Consider the diagram below.
A
B
DirectionofImprovingPerformance
Direction of Improving Cost (decreasing expense)
Each point represents a complete, unique
microgrid design.
Point “A” is the highest cost, highest
performing solution. Point “B” is the lowest
cost, lowest performing solution. There are
many options in between representing
different trade offs.
Given any point on the chart, no improvement
in cost can be made without corresponding
decrease in performance and visa versa.
This chart shows 2 objective dimensions, cost
and performance. The MDT supports up to 5
dimensions if desired. They are user defined.
Specific metrics as described in a previous
slide are combined by the user to create
objective dimensions.
In addition to views like this, the MDT has
many other views that help investigate the
solution set.
Microgrid Design Trade Space
7
Value Proposition
Using the MDT, a designer can:
 Effectively search through very large design spaces for efficient alternatives
 Investigate the simultaneous impacts of several design decisions
 Have defensible, quantitative evidence to support decisions
 Gain a quantitative understanding of the trade off relationships between
design objectives (cost and performance for example).
 Gain a quantitative understanding of the trade-offs associated with alternate
design decisions
 Identify “no brainer” choices to reduce the number of design considerations
 Perform what-if analysis by altering the input without loss of information to
include or not include certain features in a run of the solver
 Perform hypothesis testing by manually generating solutions and comparing
to the solutions found by the MDT
8
Differentiating Capability
The MDT represents an innovative capability not available elsewhere. It’s
ability to:
 Perform mid-level topology optimization
 Account for both grid connected and islanded performance
 Account for power and component reliability in islanded mode
 Account for dozens of metrics when performing the trade space search
 Present a user with an entire trade space of information from which to draw
conclusions
Make it a significant advancement over anything available to designers today.

Acknowledgements and Contacts
Development of the MDT has been funded primarily by the Department of
Energy Office of Electricity Delivery & Energy Reliability. We would like to
thank Dan Ton, manager of the Smart Grid R&D program who has provided
our funding.

4.2_Microgrid Design Toolkit_Eddy_EPRI/SNL Microgrid

  • 1. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000. SAND No. TBD. Microgrid Design Toolkit (MDT) 29 August 2016 John Eddy, Ph.D. Microgrid Design Toolkit (MDT) Principal Investigator System Sustainment & Readiness Technologies Department Sandia National Laboratories, Albuquerque, NM jpeddy@sandia.gov 1 SAND2016-8151 C Unclassified Unlimited Release
  • 2. MDT Purpose The Microgrid Design Toolkit (MDT) is a decision support software tool for microgrid designers in the early stages of the design process. The software employs powerful search algorithms to identify and characterize the trade space of alternative Once the trade space has been characterized, the software provides many views and features to help explore that trade space to extract information design decisions in terms of user defined objectives. Common examples of such objectives are cost, performance, and reliability. 2
  • 3. Progress  MDT 1.1 Beta is now available for download from http://www.energy.gov/oe/services/technology-development/smart- grid/role-microgrids-helping-advance-nation-s-energy-syst-0  Has been downloaded more than 400 (unique) times since posting on 4/6/16.  Several organizations have agreed to review the software  Port of Los Angeles  MelRok  IPERC  Burns & McDonnell  MIT Lincoln Labs  Further development is underway with the US Marine Corps. Improvements to both the analytics and the user interface are in progress. 3
  • 4. Uses The US Marine Corps Expeditionary Energy Office (E2O) used the MDT to assess microgrid power systems and Mobile Electric Hybrid Power Sources (MEHPS) for expeditionary units and brigades. Over 70 microgrid models were developed in the MDT and used to provide design support for these islanded power systems. The SPIDERS Program used a predecessor to the MDT to develop the preliminary microgrid designs for 3 military bases. • Joint Base Pearl Harbor–Hickam • Fort Carson • Camp Smith These microgrids are currently in operation on these installations The City of Hoboken, NJ used a predecessor to the MDT to develop the preliminary microgrid design for backup power in response to Hurricane Sandy. The primary goals of this design effort were to mitigate the impacts of extreme flooding on the distribution systems and electricity service throughout the city. Current uses of the MDT include: • Continued use for the Marine Corps • A backup power system assessment and Microgrid Design of the UPS Worldport facility in Louisville, KY. • A backup power system assessment and Microgrid Design of the city of New Orleans, LA. 4
  • 5. Usage What would a designer do with the MDT? What are the input requirements? A designer would input the details of their design problem in terms of:  Microgrid topology (busses, lines, transformers, generation sources, storage assets, loads, …). In addition to fixed topology, one can define topological decision points. Examples could include how big a generator should be, whether or not a battery or PV system should be included, whether or not redundant connections are needed.  Design Goals. The MDT has many built-in metrics that can be computed to determine the quality or “goodness” of a microgrid design. The user can choose which ones to use. Some examples are Purchase Cost, Energy Availability, Quantity of Fuel Used. 5
  • 6. Usage (cont.) What kinds of questions can the MDT answer?  Example MDT analysis questions:  “Should the existing generator on building A be replaced? If so, what type should the new one be and how big should it be?”  “Should we build a new building to house additional generation assets and if so, what generation assets should be used and how and where should the building be connected to the grid?”  “Should we install a new redundant backup feeder on our microgrid?”  “Should we add a PV installation and if so how big? Also, if we add one, should we also add a battery to support it and if so, how big should it be?”  “Should we include building X on the other side of the compound in our microgrid or should it remain isolated with its own backup generation?”  “We have a new load to include on our installation and may put it in building A, building B, or building C. Which should we put it in or does it not matter?” 6
  • 7. Usage (cont.) The MDT produces a set of solutions that represent efficient trade offs amongst the design objectives. Consider the diagram below. A B DirectionofImprovingPerformance Direction of Improving Cost (decreasing expense) Each point represents a complete, unique microgrid design. Point “A” is the highest cost, highest performing solution. Point “B” is the lowest cost, lowest performing solution. There are many options in between representing different trade offs. Given any point on the chart, no improvement in cost can be made without corresponding decrease in performance and visa versa. This chart shows 2 objective dimensions, cost and performance. The MDT supports up to 5 dimensions if desired. They are user defined. Specific metrics as described in a previous slide are combined by the user to create objective dimensions. In addition to views like this, the MDT has many other views that help investigate the solution set. Microgrid Design Trade Space 7
  • 8. Value Proposition Using the MDT, a designer can:  Effectively search through very large design spaces for efficient alternatives  Investigate the simultaneous impacts of several design decisions  Have defensible, quantitative evidence to support decisions  Gain a quantitative understanding of the trade off relationships between design objectives (cost and performance for example).  Gain a quantitative understanding of the trade-offs associated with alternate design decisions  Identify “no brainer” choices to reduce the number of design considerations  Perform what-if analysis by altering the input without loss of information to include or not include certain features in a run of the solver  Perform hypothesis testing by manually generating solutions and comparing to the solutions found by the MDT 8
  • 9. Differentiating Capability The MDT represents an innovative capability not available elsewhere. It’s ability to:  Perform mid-level topology optimization  Account for both grid connected and islanded performance  Account for power and component reliability in islanded mode  Account for dozens of metrics when performing the trade space search  Present a user with an entire trade space of information from which to draw conclusions Make it a significant advancement over anything available to designers today. 9
  • 10. Acknowledgements and Contacts Development of the MDT has been funded primarily by the Department of Energy Office of Electricity Delivery & Energy Reliability. We would like to thank Dan Ton, manager of the Smart Grid R&D program who has provided our funding.
