According to Embedded Systems Conference (ESC) in a group of experts to say, smart grid is facing many challenges, including ensuring the security of communications equipment to the understanding of consumer behavior.

"There are many issues to be resolved." United States National Institute of Standards and Technology (NIST)-led National Coordinator smart grid standards GeorgeArnold said.

"There is one area where we really need to do more work, that is dealing with electromagnetic related problems. For example, the so-called suitcase bomb (suitcasenuclearbombs) or solar storms (solarstorms)" Arnold said. "The military's system of dealing with electromagnetic pulse, but not practical, so we need better physical and electrical design to address these impacts." He added.

Arnold and other engineers are very confident of the importance of ensuring the future of digital, network-based grid security.



The security of smart grid

"We have the best talent in the world to realize how to protect the power grid," Arnold said, "I think the problem is not design products, but the use of practice, this is where the difference."

To ensure the safety of intelligent design has become the new mantra network engineers, ChrisKnudsen said that he was responsible for PG & E smart grid standards and architectures, "I am very confident that we have adopted a best practice approach, we have done our best." Knudsen said .

We have a laboratory, including a complete substation and a substation outside the corporate firewall, Knudsen said: "We will here the results tested for the experimental device, so as time goes on, services scope, we will have more confidence in the future. "

Smart grid will also promote a series of new generation communication systems, these new communications system will not only security but also can be suitable for harsh conditions and has a longer service life. Cisco Systems Intelligent Network Department of New Business Development Manager, said Michael Fuller MichaelFuller said: "If I want an electric pole on the deployment of a router, required to pay a high cost can be achieved, it must be reliable."

As standard, NIST released late last year, the framework of a smart grid, but "it is more of an artist's first draft and sketches - of course, is the high standard of water." Arnold said.

For example, "a lot of work in the industry, such as renewable energy sources such as solar photovoltaic DC and turn it into AC power for the power inverter interface between the richer", Knudsen said.

At the same time, a charge for connecting consumer electronics devices to energy-saving standards for power line home network committee is making headway. Is expected to open in May's meeting, the details of its latest standards, Arnold said.



Not yet clear consumer demand

"Consumers are God," advocating a broad coalition of smart grid - GridWise Union President KatherineHamilton said, "We need a better effort to figure out how the actions of consumers," she said, and pointed out that the establishment of a market research group .

"We also need to figure out how to calculate the investment over time, benefit, this bit difficult because we do not know how consumers interact with the grid." Hamilton said.

Economic benefits exceed the cost of the facility to deploy the new system the cost to get approval, PG & E's Knudsen said, "Before we introduced these devices, most of the problems we do not understand that we need to learn a lot." He concluded.
