Smart grid transformers and electricla switching stationIn 2000, the Chicago Board of Trade was hit with a power outage. Although that blackout only lasted for one hour, it created $20 trillion in delayed trades. We may think that blackouts aren’t a big concern to us personally since they don’t happen often. As our population and consumption of energy continue to increase, though, the constraints of the current electricity infrastructure are becoming more and more apparent.

 

 

The Department of Energy (DOE) is currently doing intensive research to update our nation’s electric grid. A smarter system will function more efficiently, be more reliable, stay affordable, accommodate traditional and renewable energy and reduce our carbon footprint. While the DOE does recognize the magnitude of this mission, it believes that by the year 2030, the power distribution grid as everyone knows it will forever be changed. So what is a Smart Grid anyway?

 

Smart Grid Evolution

 

The Smart Grid configuration is a fusion of available sources of energy, which is delivered to the consumers using transmission and distribution systems. In the first stage, the raw electricity is delivered from the power generation source to distribution substations. In the second stage, electricity will then be delivered from substations to the end users or consumers.

 

At first glance, a casual onlooker might not find anything astounding about the system. Upon further review, however, one would discover that at the heart of the Smart Grid power infrastructure lies an automatic distribution technology, which enables the delivery of electricity to occur in a highly efficient manner.

 

Try to visualize your house with the lights on in every room. Now, you would not want to waste energy by keeping an unoccupied room lit, would you? One of the features of the Smart Grid power infrastructure would be similar and fully automated.

 

This means that the power supply available in a particular area would be automatically tailored to fit the existing demand of a given electricity market. The excess power could then be delivered to other areas with a higher demand. Now that is definitely energy efficiency at its best!

 

Smart Grid Mission: Innovation

 

As electricity demands soar, little has been done to transmit and distribute energy where it’s needed. Obvious signs of the current grid’s limitations show themselves in the form of power outages and rolling blackouts. To combat these inefficiencies, the Smart Grid is designed to minimize power outages. According to the DOE, power outages have the propensity of causing huge losses to various industries. The rolling blackout in Silicon Valley, for instance, reported a loss of around $75 million. In fact, high tech companies, such as Sun Microsystems, estimate losses of $1 million/ minute when a blackout occurs.

 

The Smart Grid Task Force has been created to coordinate development, research and develop projects, and monitor smart grid governmental activities. The strategic goal of reducing carbon emissions is of high importance. If just a 5% increase in efficiency were achieved, the benefits would rival the reduction in greenhouse gas emissions of 53 million cars. The vision of the DOE’s Smart Grid power infrastructure is near zero downtime and lost productivity. That is, if one substation goes off the grid, the rest of the distribution will not be affected. This might seem pretty ambitious. But with the advanced technologies modernizing the electric grid, the DOE believes that it can be done.

    I just found an update on the smart grids data standard. The new standard by the North American Energy Standards Board (NAESB) will allow utilities and customers to exchange detailed information about electricity usage in a consistent format. This will enable consumers to track their electricity usage and help them better manage their energy consumption and costs. Once the model is a ratified it will be included in NAESB's filing with the Federal Energy Regulatory Commission sometime in March of this year.


    "This standard establishes the foundational energy usage data structure for the Smart Grid," said David Wollman, NIST lead on the SGIP team. "It provides the basis for multiple additional standards and resulting applications that will empower consumers to more easily monitor and then modify their energy usage and reduce their costs."
