What is an Intelligent Building?
An intelligent building can control its
internal loads to make them operate more
efficiently, while maintaining end-user
comfort.
Such a building is equipped with:
-Energy management systems (EMS), or- Building automation systems (BAS).

HVAC Control System
w/ Smart Thermostat
Can program room temperaturesettings during different periods of
the day
Can learn how long the furnaceand AC take to reach programmed
temperature settings
Can force the compressor to waita few minutes before restarting toprevent equipment damage

What is a Microgrid? A microgrid is a subset of an electric power system, generally located at
the distribution level. It is a coordinated electrical subsystem with:
multiple distributed energy sources, loads, a section of network and is
capable of operating independently from the grid.

Microgrid Illustration
At a minimum, a microgrid can comprise a single customer with localgeneration and loads. A part of the distribution feeder, or the whole
distribution feeder, or the whole distribution substation can also be
considered a microgrid

Thermal ice storage can be used to shift some of the daytime load to nighttime.

Multi-Agents
What is a multi-agent system?A multi-agent system is a collection of several software agents workingtogether that are capable of learning from, interacting with and reactingto the changes in environment and sometimes taking initiatives toachieve overall goal of the system.

Intelligent Agents for Building and
Microgrid Controls Agents can be used to monitor, control and supervise loads and
generators in buildings or microgrid systems.

Conclusions
15
Multi-agent systems can be used forbuilding/microgrid control
This is a proof-of-concept that creates anenvironment such that building and/or
microgrid loads can be made available as a
virtual storage unit during an emergency
