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
