Smart Grid Dispatching
Technology Supporting System
fit weak interconnection grid for dispatching
and applied in independent control center

Future National Grid Interconnection
and UHV AC/DC Transmission Systems

2020
UHV Planning
2013
•From weak interconnection to
strong interconnection in
National Grid

Future Operation Supporting System
Research Objectives
• Unified power grid dispatching and unified power grid
management among multiple control centers
•Extend larger monitoring scope, more real-time data and
more comprehensively information for sensing the operation
state
•Combine new IT technique and dispatching demand

Dispatching-cloud Concept
— Based on Cloud Computing technique
— Form a new IT infrastructure management and
service delivery mode
— Integrate application data and IT resources
distributed in each control center
— Construct an abstract, virtual and dynamically
scalable dispatching resource pool
— Provide unified on-demand service for grid
operation supporting

Aspect of System with Dispatching-cloud
• Dispatching entity is distributed, and the system offers an unified service.
• The system includes 3 layers, dispatching entity, service center and end-user.
• SCADA remains in local position.

Dispatching-cloud System Prospects
Evolution process from existing dispatching
system to future dispatching-cloud system.
— Improve degree of centralization,
— Reduce the distribution node
— Centralize service function
— Form dispatching-cloud service center
— Construct 2 or 3 dispatching-cloud
service center
— Original local dispatching center turns
to desktop cloud applications.

Dispatching-cloud System
Key Technologies Prospects
• Cloud Computing: offers a framework of
future system.
• Cluster Technology: improve the efficient
of data process
• Big Data Technology :
Unstructured data (video/audio)
semi-structured data store (CIM XML,
CIM/E, CIM SVG, CIM/G etc)
distributed database
• IPv6 Application: extend network address
for more terminals.
• Dynamic Visualization: have the intuitive
feelings of power operation status and
trend .
