8 Department of Computer and Information Technology (CIT) A B C D E F Power ONOFFON OFF ON: Send Request OFF: No Request Desired Power Generating Power

9 Department of Computer and Information Technology (CIT) A B C D E F Power NOYESNO YES NO: Decline YES: Accept Desired Power Generating Power B and C should not be equally considered!

10 Department of Computer and Information Technology (CIT) Expert Knowledge (http://en.wikipedia.org/wiki/Fuzzy_logic) 0.8, fairly cold 0.2, slightly warm 0.0, not hot

11 Department of Computer and Information Technology (CIT) A. d is NB Δd is PM so, output y will be NB, which means this agent doesnt have spare electricity, and even it has to request other agents to borrow large electricity. B. d is PM Δd is PS so, output y will be PS, which means this agent has small spare electricity to lend other agents who are the lack of electricity. C. d is PM Δd is NM so, output y will be NS, which means this agent is going to the lack of electricity, so it need to request more electricity to other agents. D. d is NS Δd is NB so, output y will be NM, which means this agent is the lack of electricity, so it should request more electricity to other agents. A B C D E F Desired Power Generating Power

12 Department of Computer and Information Technology (CIT) A : d is PB and Δd is PS. So, output y is set to PB, which means this agent will have more spare power. B : d is PB and Δd is NS. So, output y is set to NS, which means this agent will slowly experience the shortage of power. C : … D : … E : d is PS and Δd is PB. So, output y is set to PM, which means this agent will have more spare power. F : d is PS and Δd is NB. So, output y is set to NB, which means this agent will quickly experience the shortage of power.

14 Department of Computer and Information Technology (CIT) Agent1 will experience the shortage of power when agent2 has spare power. Sampling time = 10Hz No Limitations with respect to batteries charging No Loss of energy/electricity during transmission Agent 1 (Query Agent) Agent 2 (Lender Agent) Negotiation

18 Department of Computer and Information Technology (CIT) Agent 1, (a) Original power (b) Output y from the fuzzy logic (c) Request signal (1 = request, 0 = no request) (d) Needed power (e) Accept signal (1 = fully accept, 2 = partially accept, 0 = no response) (f) Lending power (g) Final power

19 Department of Computer and Information Technology (CIT) Agent 2, (a) Original power (b) Output y from the fuzzy logic (c) Request signal (1 = request, 0 = no request) (d) Needed power (e) Accept signal (1 = fully accept, 2 = partially accept, 0 = no response) (f) Lending power (g) Final power

20 Department of Computer and Information Technology (CIT) We intended to utilize artificial intelligence (Fuzzy Logic) and multi agents system in our research to build a micro-turbine smart grids. By implementing two agents having the same construction, but with different amount of power, we verified that they successfully negotiate with each other so that both of them did not experience the shortage of power. Our research could be seen in areas where electricity is not currently connected to a grid such as developing countries and battlefields.

21 Department of Computer and Information Technology (CIT) We have taken distributed approach in this project, another approach that can be considered is centralized. A hybrid system can be built if we take both these approaches together. We are currently incorporating these findings by building a real micro grid wind system, in order to move on the next step towards our final goal of this project that is to help the people in under-developed countries to access cleaner and cheaper power thus improving their status of living.
