Presentation Outline
Untrustworthy Laboratories (Most frustrating). Sudden Power Outage.
*Lecture rooms (Inefficiencies such as noise in class, backward progress of course content and so on).*Hospitals (Most machines are power reliant).*Agriculture (Freezers and incubators).

GRID SYSTEM EVOLUTION(Destination Point)
Original Grid system is debulked. The MAS reduces the hierarchical levels of control (each
distributed agent is assigned a role and performs independently). Quick (almost instant) response to situations. Maintains continuity of operations. Adaptation to situations as they vary with time.
Problem Solved!
ENERGY FLOW MANAGEMENT Let’s think of this as the big eyes of Jesus
watching all of us. It involves monitoring all the DERs and
autonomous loads while registering the data and making smart decisions simultaneously.
We’d want to ask ourselves what energy profiling is all about and what data is being acquired in the smart microgrid!
In details, energy profiling is all about the following:DAILY ENERGY AVAILABLE
Controls each user’s demand. Rewards efficient use of energy.POWER CONTROL Maximum power control per user.
LOAD MANAGEMENT Disconnection of non-vital loads. Connection of auxiliary loads when there is surplus energy.
OVERALL MANAGEMENT Integration in the micro network management system. Measurement of power quality and user consumptions.
ENERGY PROFILING
In summary though, energy profiling is determining the energy profile of the constituents of the smart microgrid which include:Consumption profile of the autonomous loads andDynamic generation rate of the DERs.
ENERGY PROFILING
This involves: Interactive Maintenance: Monitoring, Preventive Maintenance: Statistical Data
and Emergency Maintenance: Alarms.
• In my own words, I’d say it involves the interoperability of all the microgrid constituents.
DATA ACQUISITION
• Possible Technologies for Energy Management
• Many people have worked on this aspect of the project and each one of them has employed a systematically different approach with respect to software technology. Some of these I’ve discovered to be: Supervisory Control And Data
Acquisition(SCADA) Java Aided Development Environment(JADE) MATrix LABoratory (MATLAB)
