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
Source AgentsGraphic user interface
(GUI) createdQt program used for
creation of GUIRaspberry pi usedFunctionality
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
Main Agent
GUI created Qt program used
for creation of GUI Raspberry pi usedFunctionality
Determines the power demand
Necessary CalculationsLoan Calculations for cost per hour
P = loan payment per hour = [iA/(1 – (1 + i))^-L]/748.5
A = Investment pricei = annual interest rate = interest rate/12L = length of loan in months
Loan Calculations for Cost per MonthQ = P/(3600s/time of iterations for update) =
price/iterationW = (748.5hrs/month) x (3600s/time of iterations
for update) = iterations/monthP = Annual monthly payment = (Q) x (W)
Company Owned Cost Calculations($/kWh) x (power of source x 1 hour)
JADE NetworkDetermines which source(s) meets the
power demand at the cheapest costDetermines which source(s) will be
turned on/offSends finalized binary type data to
representative voltage switch
Representative High Voltage SwitchPlug and play component to prove which
source(s) are in use

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
