IntelliGrid Architecture
The IntelliGrid Project (previously known as the IECSA Project)
was sponsored by the
Electric Power Research Institute
(EPRI). The project had two
objectives:
1) The identification of current and future
Power System
Functions thus determining the
Business
Needs of power system operations
requirements for the power system of today and in the
future, including
self-healing grid concepts. These power system functions were the drivers
for the development of the IntelliGrid Architecture.
2) The
development of the IntelliGrid
Architecture which used these power system functional,
configuration, and performance requirements as the
basis for the information requirements necessary
to support the envisioned power system of the future, building
toward a Strategic Vision,
using a
Tactical Approach based on
IntelliGrid Environments and technology
independent techniques, based on
Standard Technologies and Best Practices.
In addition,
Guidelines and
Recommendations are
focused on the different users of the IntelliGrid
Architecture so that they can understand the concepts presented by the
IntelliGrid Architecture, utilize the methodology for developing projects,
assess the identified standards and technologies for applicability to their
projects, and thus use the IntelliGrid Architecture effectively to pursue their
goals.
These two objectives
reflect the concept that the future energy system is really an architected
blend of two infrastructures: an energy delivery infrastructure
and a supporting information infrastructure. Progress is necessary within both of these infrastructures to
effectively create the envisioned future energy system.
IntelliGrid Architecture Project Team
The IntelliGrid Architecture Project
was developed by a large team of experts. The IntelliGrid
Project was
managed by General Electric,
with major contributions from
Utility Consulting
International (UCI),
SISCO, Lucent,
EnerNex, Hypertek,
and many Stakeholders. As
seen in the figure, the process involved two types of
experts: the power system function experts and the
architecture experts:
1.
Power System Function Experts. Described existing and
future functions related to power system operations which rely on
exchanging information across distributed systems. These functions
were captured in narratives by power system experts and analyzed
through the use of Unified Modeling Language (UML) Use Cases. Each
function was deconstructed into a series of steps; each of the
steps were then linked to an IntelliGrid Environment that best
captured the information requirements (configuration, quality of
service, security, and data management) for that step.
2.
IntelliGrid Architecture
Experts. Developed the IntelliGrid Architecture based on the
information requirements of the power system functions, and linked the
IntelliGrid Environments to the recommended state-of-the-art standards
and best practices.
