Smart grid standard falls short of interoperability

A group that has been working to set standards for home area networks in the United States has agreed on a co-existence mechanism for powerline networks in the country. However, the government-led group opted not to require interoperability for a number of competing approaches.

The members of the group say that the unanimous agreement on a non-interference approach is a victory. But it's not clear if manufacturers of home appliances and gateways agree that the standards will help them build networked products.

More than a year ago, Whirpool Corp. made a public commitment to ship a million dryers ready to plug into a smart electric grid if there was a suitable networking standard the company could use. Organizers of the government-led standards effort said they didn't want the lack of a standard to make Whirpool renege on that promise.

The powerline agreement came in a December 2 vote of the so-called Priority Action Plan 15. PAP-15 is one of a broad set of standards efforts under the Smart Grid Interoperability Panel convened by the U.S. National Institute of Standards and Technology.

The PAP-15 harmonizes two existing implementations of a co-existence mechanism for powerline. Both IEEE 1901 and ITU use the so-called Inter-System Protocol (ISP) method of co-existence originally proposed by Panasonic.

However, "the two recommendations went through separate comment resolution phases conducted by the two independent groups and this resulted in producing a slight incompatibility between the two mechanisms," said Stefano Galli, lead scientist, Panasonic, who helped define ISP and led the PAP-15 group.

In its latest report, PAP-15 recommended the smart grid group mandate that all current and future broadband powerline networks use one of the now-interoperable non-interference approaches. The move is "a refreshing success story [given] the often acrimonious state of the PLC industry," said Galli.

"Coexistence does not replace interoperability nor [does it] narrow down the choice of which PLC technology to deploy, it only solves the problem of mutual interference created by deploying non-interoperable technologies," said Galli in an email exchange.

Market selection
The market, not a standards group, should define what home network technology is best for appliances and other consumer systems, he said. "Coexistence will allow the industry to align behind the right PLC technology for the right application on the basis of field deployment data and market selection not on the basis of questionable and subjective pre-selection strategies," he said.

The outcome "accomplishes the objective" of the group, said George Arnold, national coordinator of smart grid standards at NIST. He agreed with Galli that market groups, not standards efforts, should make final decisions on which networking approaches are best for smart grid links in the home.

"We have been encouraging the Association of Home Appliance Manufacturers to study the needs of this industry and evaluate the available communications options against their requirements," said Arnold. "They have recently released a report which provides recommendations that should be helpful to the appliance industry in choosing communications interfaces for appliances," he said in an email exchange.

At least four major broadband powerline technologies are currently in use—HomePlug AV, HD-PLC, the LonWorks technology of Echelon and a powerline variant developed by the former DS2, now part of Marvell. Chips for a fifth approach, based on the ITU standard, are in development by as many as eight companies.

Powerline is just one of several media for energy monitoring networks in the home. The Wi-Fi Alliance is also studying use of that technology for such nets.

Well to all of those Libertarians out there, at least they want the "market" to determine the best standards to enslave you instead of the goobermint "bureaucrats" at NIST decide.  Isn't the NWO so loving, and so Libertarian?  You should take them up on their offer of the false illusion of choice.

PAP15: Harmonize Power Line Carrier Standards for Appliance Communications in the Home

Read all about it here:


Smart home appliances represent a major part of the Smart Grid vision aimed at increasing energy efficiency and, to achieve this goal, home appliances need to communicate with entities and players in other Smart Grid domains via home networks. The implementation of such home networks must enable plug and play of appliances from the same or different vendors, requiring no manual configurations by homeowners. Power line communications (PLCs) is a potential technology that is used today in home networks and could also be used for appliance communications for Smart Grid applications.

The effective use of PLCs is impeded by the existence of multiple and non interoperable technologies currently under development in various standards setting organizations. Relevant standards include ITU G.Hn (G.9960, G.9961, G.9972), IEEE P1901 (HomePlug ™, HD-PLC™, and ISP), and ANSI/CEA 709.2 (Lonworks™). Since these technologies do not interoperate, their operation in close proximity may cause harmful mutual interference when operating in the same band and at the same time and this may lead to severe performance degradation or even malfunctions in both Smart Grid and home networking applications. This problem is compounded by the fact that PLCs are also used in the same frequency band for other non Smart Grid applications, such as entertainment, A/V, etc.

PAP-15 will address this issue and will focus on the harmonization of PLC standards for appliance communications in the home.

Since one of the potential acceptable outcomes of PAP-15 (see Objectives below) is to achieve coexistence among multiple PLC technologies, a PAP-15 "Coexistence" subgroup was formed. Coexistence is an issue for all PLC technologies operating in the same frequency band and at the same time, not only an issue for appliance communications. Furthermore, coexistence issues apply to both broadband devices (operating in the 1.8 MHz and above band) and narrowband devices (operating below 500 kHz). The purpose of this PAP-15 Coexistence subgroup is to make a recommendation to NIST on what the value of coexistence in the Smart Grid is and which coexistence mechanism(s) should be added to the list of Smart Grid standards.

Good topic!

So how do you see standards and regulation playing out in a "good society"?

I see them as obvious adoptions, as a businessman. It just makes sense to cooperate with your fellow man, even your competitors, because it's all fair game and it just makes sense. It's not a rigged game! People want, you make, and if it's a light bulb, it better fit in your customers' socket or you're going belly up. Where's the "government" in that?
