Transcript of Smart Grid

This is a system that will require various contractors. Specialists will be needed for:

- Construction (control buildings etc)

- Transmission Lines

- Electrical Engineers for the construction of the smart devices

- Software Engineers to develop the information processing component of the control system

Research - US, Canada, The European Union and Australia

Reduction of peak load: 3% - 6%

Time-of-Use-Pricing
Critical Peak Pricing
One-two-way ahead predictions
One-to-six-hour-ahead prediction
Advanced Electricity Pricing
Research - US, Canada, The European Union and Australia

Reduction of peak load: 12% - 38%

SELECTED
Renewable Resource Forecasting
COMBINED: + precise predictions
CONTRACTORS
Smart Grid
Project
Requires many formalized plans

Incorporates the existing grid and it’s technologies

In practice, additions of smart devices are implemented as individual projects

These projects would require their own iteration of the systems engineering development cycle
PRODUCTION AND DISTRIBUTION
Installation should not interrupt power supply

Needs to integrate with old system

Large scale operation

Needs:
to have a reliable and efficient power grid;
to meet the increase in electricity demand;
to reduce carbon dioxide emission.

WHY DO WE NEED A SMART GRID?
Traditional grid has deficiencies!

AMI
SELECTED SMART TECHNOLOGY
-Find the influence of Key Communication Factors
-Test Performance of Smart Metering Infrastructure
OUTLINE
LOAD REDUCTION
Decrease of the energy load peak.
Expected reduction in peak load = 3%.


DEMAND RESPONSE
Real time interaction - minimizing demand peaks
- performing a demand forecasting
Required reduction in peak demand > = 5%.


DISTRIBUTED GENERATION
Consumers generate power on their place by themselves.
Use of renewable energy.
Expected reduction is $ 20 million in 20 years Energy generation and delivery

PROJECT TIMELINE
SPIRAL LIFE CYCLE MODEL
IN SERVICE SUPPORT
Service is required as long as the system is operational

Permanent staff are needed to deal with disturbances and damage to the system

Part of the benefit of a smart grid is that it reacts better to these disturbances
SYSTEM UPGRADES AND RETIREMENT
Newer systems are built to incorporate the old ones

Hence, retirement for this system will be the same as a major system upgrade

The system design needs to take into account the development of new technologies that will supersede this system

Components should be retired by experts as needed
