“A group of interconnected loads and distributed energy resources with clearly
defined electrical boundaries that acts as a single controllable entity with respect
to the grid and can connect and disconnect from the grid to enable it to operate in
both grid-connected or island mode.”

What is autonomous control?
.. lighting the way to a brighter future

Navigated and maneuvered by a computer without a need
for human control or intervention under a range of situations
(use cases) and conditions (contingencies)
The act or power of exercising restraint or direction over;
regulation; domination, or command of other

Process Models
DEVICE KNOWLEDGE
TEMPLATES
Generic descriptions of process models
that are created dynamically
A priori knowledge of quantity and types
of devices is not necessary
MODEL RE-CREATION
Models are recreated if equipment enters or
leaves the grid
SMART DATA STREAMS
Includes additional information about the device
and meaning of its values

Configuration Files
CONTROL STRATEGIES
PROCESS MODELS
Generic descriptions of process models
that are created dynamically
Designate controls strategies including
contingency operations
USER PREFERENCES
Stipulate user preferences depending on the type
of microgrid and the operator’s preferences
COMMUNICATION PROTOCOLS
How an individual computer communicates with
microgrid equipment and services

Control Strategies
SIMPLE MODELS
TEMPLATES
Templates can include actions to be taken
when the model outputs cross certain thresholds
Models can be a simple summation
of loads
COMPLEX MAPPINGS
Models can also be complex mappings that implement load shedding
based on available generation capacity and expected/requested loads
EMBEDDED KNOWLEDGE
Knowledge and expertise embedded in templates
that use metadata to create process models

Then
Now
An effective microgrid control system must be
able to function in the face of disruptions to
connected devices, data communications, or the
control system itself. Running control algorithms
on a single central computer is an unacceptable
single point of failure in modern system design,
yet most microgrid control systems are stuck
with this obsolete approach.
GridMaster takes a fundamentally different and
modern approach by distributing control
functions across multiple control computers that
constantly communicate and cooperate in
optimizing microgrid performance. If one
controller goes offline, another takes up its role.
