  1. Energy Management System for Micro-Grid University of West Florida Electrical and Computer Engineering Department Group Members: Joseph McPalmer, Lindsey McCambry, Chris Quesada, Joseph Flaws Advisor: Dr. Ramachandran

  2. Table of Contents • Purpose of System • Technical Approach towards Source and Main Agent • Necessary Calculations • JADE Network • Representative Voltage Switch • Parts List • Conclusion • Special Thanks and Questions

  3. Purpose of System • Energy Management System in Micro-Grid Community • Used the University of West Florida (UWF) as a model for the system • Obtained daily and yearly power load profile from UWF

  4. Source Agents • Graphic user interface (GUI) created • Qt program used for creation of GUI • Raspberry pi used • Functionality • Determines cost for both loans and company owned sources • Determines output power for sources • On and off peak hour costs were implemented into the system

  5. Main Agent • GUI created • Qt program used for creation of GUI • Raspberry pi used • Functionality • Determines the power demand

  6. Necessary Calculations • Loan Calculations for cost per hour • P = loan payment per hour = [iA/(1 – (1 + i))^-L]/748.5 • A = Investment price • i = annual interest rate = interest rate/12 • L = length of loan in months • Loan Calculations for Cost per Month • Q = P/(3600s/time of iterations for update) = price/iteration • W = (748.5hrs/month) x (3600s/time of iterations for update) = iterations/month • P = Annual monthly payment = (Q) x (W) • Company Owned Cost Calculations • ($/kWh) x (power of source x 1 hour)

  7. JADE Network • Determines which source(s) meets the power demand at the cheapest cost • Determines which source(s) will be turned on/off • Sends finalized binary type data to representative voltage switch

  8. Representative High Voltage Switch • Plug and play component to prove which source(s) are in use

  9. Parts List

  10. Conclusion • Energy Management System in Micro-Grid Community • 9 raspberry pis used • 7 source agents = determined cost and power output • 1 main agent = determined power demand • 1 voltage switch = plug and play component

  11. Special Thanks and Questions • Dr. B. Ramachandran • Dr. M. Khabou • Mr. B. Sherrell • Mr. G. Davies • Mr. B. Gillis • Mr. M. View • Qt Forum • Raspberry Pi Forum • Google
