term that covers modernization of both the transmission and distribution grids. http://en.wikipedia.org

Smart Grid is a new market being built around the modernization of the electrical grid, green power generation and more efficient usage of electrical power. Terry Chandler, Power Quality Inc Aug

PG&E (California)“ Smart Grid is not a thing or a

specific project. It is about how the utilities leverage technology to enhance their entire portfolio of business processes.”

Andy Tang, an executive at the PG&E utility in California,

Xcel Energy (USA)• Xcel Energy’s vision of a Smart Grid includes a fully network-

connected system that identifies all aspects of the power grid and communicates its status and the impact of consumption decisions (including economic, environmental and reliability impacts) to automated decision-making systems on that network.

• This vision leverages the multitude of vertical system solutions currently available and deploys a horizontal integration of these systems into a real-time, automated “neural network” that will manage all of the variables involved in delivering energy to the consumer.

• We believe this vision of an advanced decision-making system will allow Xcel Energy to more efficiently deliver energy while providing consumers with valuable information for better decisions on when, where and how to consume energy.

• The impact will be a greatly improved delivery system that optimizes the impact on the environment, ensures the most efficient delivery, and maximizes reliability.

As defined by large utilities in the USA• Duke Energy’s long-term vision is to transform

the operation of its electric power grid by creating a reliable and scalable networked infrastructure capable of delivering and receiving information from intelligent devices distributed across its power systems, automating components of the distribution systems and leveraging the linked networks for improved operational efficiencies and customer satisfaction.

• Duke Energy is 3rd largest utility in USA (Kwhr sales)

Technology Advancement 7. Increased Efficiency Through Grid Optimization 8. Advanced Consumer Services9. Infrastructure Reliability and Security 10.Demand for 21st Century Power Quality

1. “Digital economy Power Quality”

US Department of Energy

• Governments and their desire to show action to the voters. “ Green power” ; new high tech jobs; new business

• Utility owners and their desire for increased return on investment with reduced operating costs and improved reliability and quality of supply. (QOS)

• Operations management and their desire to lower operating costs and integrate new technology

• Engineering management and their desire to modernize the network and it’s operation with new technology

• Technology advances in almost every aspect of the utility business that have not been adopted because of the extreme conservative nature of the electrical utility business.

Drivers of the Smart Grid Asia

The intelligent grid utilizes technology in three important ways:• 1) Automating the grid to harden it and make

it less costly to operate.

• 2) Integrating the electric grid to create an end-to-end network for quickly acquiring and transporting data from millions of end points

• 3) Expanding the value of the grid beyond typical utility needs to support new services and new markets offered by energy retailers.

Some of the Standards for SmartGrid

Comparison Current Grid to Smart Grid

Smarter Grid today- Substation automation (SA) enables utilities

to plan, monitor, and control equipment in a decentralized way, which makes better use of maintenance budgets and boosts reliability.

- Smart meters allow utility customers to participate in time-of-use pricing programs and have greater control over their energy usage and costs.

Smarter Grid beginingsSmart grid technologies in use today Utility companies

are already implementing “smart” devices in various ways. Some examples of how smart technologies—and the practices they enable—can impact the operation and overall health of the grid include the following:

- Real-time situational awareness and analysis of the distribution system can drive improved system operational practices that will, in turn, improve reliability.

- Fault location and isolation can speed recovery when outages do occur by allowing work crews to drastically narrow the search for a downed line.

Smarter grid today- SCADA/DMS (distribution management

systems) put more analysis and control functions in the hands of grid operators.

- Voltage control, through reactive power compensation and the broader application of power electronics, increases transmission capacity of existing lines improves the resiliency of the power system as a whole.
