Industry News Long Island Power Authority (LIPA) has selected Landis+Gyr to deploy a smart grid demonstration project that will test consumer response to dynamic pricing signals, as well as the scalability of smart grid technology in the Route 110 corridor located in Farmingdale, NY which is part of LIPA’s service territory. The project includes deployment of Landis+Gyr’s Gridstream RF smart grid network, along with advanced meters and in-home energy displays to consumers in the town of Farmingdale on Long Island, NY. The project area, which includes the Farmingdale State College campus, was chosen because it is representative of LIPA’s customer base in terms of demand levels and percentage of residential versus commercial customers. LIPA and its partners, Stony Brook University and Farmingdale State College, received a Smart Grid Investment Grant from the Department of Energy to fund the project. They are using this demonstration project to provide a comprehensive assessment of the benefits of smart grid technology. In addition to advanced metering, the utility is interested in solutions to automate and control distribution devices. The American Water Works Association (AWWA) has updated editions to two of its Manuals of Water Supply Practices: Water Meters - Selection, Installation, Testing, and Maintenance (M6) and Computer Modeling of Water Distribution Systems (M32). Accurate water metering is the means by which water utilities produce revenue to cover expenses and equitably charge customers. Meters that are not sized correctly, maintained properly or replaced before they become too inaccurate typically under-register customer water usage, limiting a utility’s ability to generate income. Written with such issues in mind, Water Meters - Selection, Installation, Testing, and Maintenance (M6), is written, reviewed and approved for publication by AWWA members who are meter authorities. The manual covers all types of water meters used in residential, commercial, industrial and fire service applications, plus new information on singlejet and fluidic-oscillator meters, along with the latest, AWWA-approved procedures for installation, testing, maintenance and repair of meters. Computer Modeling of Water Distribution Systems (M32) addresses water utility tools for managing and operating a water distribution system. Newly revised, the manual shows how to build an accurate computer model of a water distribution system and how to use modeling to solve many problems of hydraulics and water quality. LIPA Selects Landis+Gyr for Smart Grid Demonstration Project life of lead acid batteries in half, while the lithium-ion battery maintains the same cycle life in both environments. The lithium-ion modules analyzed included AllCell’s proprietary phase change material (PCM) composite, which improves the cycle life of lithium-ion cells by passively absorbing and distributing heat. When a battery is placed in a hot outdoor environment, the PCM can absorb heat during the day and release it back into the atmosphere at night. Including PCM thermal management in battery modules enables the production of compact, lightweight, long-lasting energy storage systems. In addition to hot environments, the technology is well suited for mobile, portable, rooftop and off-grid applications. AWWA Updates to Two Manuals of Practice The Automation Federation and the Society for Automation, Instrumentation, Measurement and Control (SAIMC) have signed a Memorandum of Membership, becoming the newest member organization of the Automation Federation. The Automation Federation and SAIMC will work together to advance the automation profession through the promotion of continuing education and training; dissemination and communication of relevant information related to and benefiting the profession and the growth and maintenance of a repository of valuable technical information, terminology and standards. “SAIMC’s leadership recognized the importance of becoming a member organization of the Automation Federation and the positive impact our involvement would generate for the automation profession,” said Johan Maartens, president of SAIMC. “Through this membership, SAIMC will be able to aid the Automation Federation in its efforts to promote awareness, programs and services that will advance the automation profession while meeting the goals of SAIMC.” The Automation Federation and SAIMC Sign Memorandum of Membership AllCell Technologies has compared the economics of lithium-ion and lead acid batteries for stationary energy storage systems (ESS). Even though the initial purchase price of lead acid batteries is one-fifth the price of lithium-ion, when analyzed on a full life-cycle basis lithium-ion batteries are now cost-competitive in moderate climates and lower cost in hot climates. As solar photovoltaic costs continue to fall, the lightweight, long life cycle and deep discharge capacity of lithium-ion battery systems will enable a growing range of off-grid products and applications to become economically feasible. The analysis included a case study of a system requiring 50 kilowatthours of electricity per day, and compared valve regulated lead acid (VRLA) batteries to AllCell’s standard ESS modules in a moderate climate of 25°C and a hot climate of 33°C. For the lead acid system, after taking into account the lower depth of discharge, climate-adjusted cycle life and increased transportation and installation costs, the total cost per kWh delivered over five years came out to $0.34 in the moderate climate and $0.67 in the hot climate. The lithium-ion system came out to $0.40 per kWh delivered, 18 pecent higher than lead acid in the moderate climate but 40 percent lower in the hot climate. The driver of this large difference is the reduced cycle life of lead acid in hot environments. The 8°C increase in average temperature between moderate and hot climates cuts the estimated cycle 28 www.RemoteMagazine.com AllCell White Paper Finds Lithium Ion Battery Costs Beat Lead Acid in Hot Environments The Fieldbus Foundation supports a new International Electrotechnical Commission (IEC) report that provides guidance to end users for selecting an industry-standard device integration technology encompassing all host systems, field instruments and device protocols. The new technical report, IEC 61804-6 Ed 1: Function blocks (FB) for process control – Electronic Device Description Language (EDDL) – Part 6: Meeting the requirements for integrating fieldbus devices in engineering tools for field devices, explains the requirements for field device integration and how they are met using the EDDL standard (IEC 61804-3). EDDL is a universal method for accessing diagnostic, real-time and asset management information contained in more than 20 million field devices. EDDL has the power to integrate field devices for optimal control strategies and consistent human machine interfaces (HMIs) across different platforms. The technology extends interoperability to the HMI and diagnostic data levels with improved visualization and graphical capabilities. The IEC report is based on the recommendations of NAMUR, an international end user association of automation technology in the process industries. The NAMUR NE105 specification was published in 2004 to clearly define requirements for device integration technologies enabling a mixture of sophisticated device types, based on different protocols, from multiple manufacturers and keeping control systems up to date with new versions of these devices. As a standard that is totally independent of computer operating systems, EDDL protects investments in control systems and devices by ensuring obsolescence cycles are not shortened by new Microsoft Windows versions. Future devices with EDDL files can be commissioned without upgrading Windows. Likewise, a new version of Windows does not require updated drivers in existing devices; new device management software can be installed while still supporting the older equipment. EDDL also avoids version conflicts with system software, since EDDL files do not require software installation for loading and are non-executable. EDDL allows operators to receive detailed information about failures of critical devices so that action can be taken before the process is affected.
