Smart Grid Testing

Smart GridWhat is Smart Grid Performance Testing?

ZigBee is currently the most popular wireless protocol for connecting smart meters, thermostats and other devices in home and commercial grid systems. There is clear value in investing in wireless testing when bringing a product to market or upgrading an existing offering with smart grid capabilities. Proper smart grid penetration testing for wireless deployments should address each of the five main reasons these systems fail:

  • RF signal propagation — Insufficient signal strength is the most common cause of smart grid system failure. A device’s final RF characteristics can be influenced by a number of factors, including the placement of chips on the circuit board, its housing materials and more. Accurate smart grid performance testing must take into consideration all of the repercussions changes to these and other design elements can have.
  • End-to-end registration  Registration of individual devices on a smart grid system is prone to errors when those devices conflict with network security requirements. Our research indicates that thorough end-to-end testing at all stages of the deployment process can reduce the risk of errors by up to 10%.
  • Interoperability — Smart grid interoperability testing takes into account the wide range of conditions encountered during real-world conditions. System failure can be caused by different date and time configurations, input errors and other common occurrences. To be truly effective, wireless testing must replicate all these potential issues.
  • Loss of power/network recovery — The ability of a smart grid system to respond to power and network outages is critical to its functionality. Making sure device settings and network information is retained during service interruptions is an important part of wireless testing, one that must be fully evaluated across a range of potential situations.
  • Functionality — Device functionality is often overlooked during the smart grid performance testing process. While it’s important for the system as a whole to be deployed according to wireless specifications, failing to prioritize the basic usability of individual devices is a critical error. During the course of smart grid interoperability testing, we are often able to uncover errors that have been overlooked at other stages of the QA process.

What is Smart Grid Performance Testing?

Whether it’s meeting wireless requirements or those of any other certification protocol, NTS is the industry leader in smart grid performance testing. With NTS industry experience in computer hardware and software technologies, wireless products, regulatory testing, as well as a host of EMC and climatic/environmental chambers, we are the perfect choice to assist with your “Smart Energy” projects. We’ve tested energy products, “smart” (computer) products, and “Smart Energy” products. We have the laboratory infrastructure and the technical staff to help bring your “Smart Energy” products to market quickly and efficiently.  NTS assists private companies and public utilities with “Smart Energy” product development and deployment in many different ways:

  • Smart Meter Testing
  • Network Testing
  • Reliability Testing
  • Environmental Testing
  • EMI/EMC & Device Regulatory Testing

NTS is also an expert in the area of wired and wireless metering network testing, and smart energy device testing. Our skills allow us to test intelligent thermostats, smart outlets, smart meters, etc. using ZigBee, IEEE-802.15.4 and its derivatives, like Matter. In addition, NTS has extensive experience in testing products with Wi-Fi, Bluetooth, HomePlug and a host of other wired, wireless, and powerline communication standards. Before you release an in-home display or smart meter or smart appliance, let us help make sure it meets the necessary standards. In fact, we can go beyond the standards to test areas that may be borderline, but problematic on large roll-outs. NTS also has an interoperability lab set up and configured to allow you to test your products with various back-ends, smart meters, in-home displays, etc. to get a better understand of the real-world into which your device is being released.

Performance testing of the products, interference with common household products, interoperability with other Smart Energy products, and peaceful co-existence with other technologies (e.g., ZigBee, Z-Wave, Wi-Fi, Bluetooth, HomePlug, etc.) are just some of the areas that can be tested.

Often it is more cost-effective to bring in a skilled consultant, like NTS, to help with an individual project, rather than spending the time, resources, and effort to identify the appropriate individual to bring in-house. This is especially true for intermittent projects, such as many of those necessary for the release of a Smart Grid device or the roll-out of a Smart Grid network to your customers. NTS has experienced, trained staff ready to assist you today to help you with your needs.

 

NIST Certification

NIST (National Institute of Standards and Technologies) has been tasked with laying out a plan for the transformation of the U.S.’s aging energy infrastructure into interoperable Smart Grid. As part of their task, they’ve put together an open forum for members to collaborate on standards development called the Smart Grid Interoperability Panel (SGIP).  NIST and the SGIP are selecting a framework of standards which are being used as the backbone of the new Smart Grid. The NIST standards includes:

  • AMI-SEC System Security Requirements (Metering & Smart Grid security)
  • BACnet ANSI (Building automation)
  • IEEE 1686-2007 (Security for intelligent electronic devices)
  • OpenADR (Price response & demand response)
  • OpenHAN (Home area network device communications)
  • ZigBee/HomePlug Smart Energy Profile (Home area network communications & information model)

NTS has the ability to test to many of these standards to help you verify your products are compatible with the NIST/SGIP Framework.
