smartgrid Peak Power Can Be Forecast reduction technology for smart cities M2M Comms for Management monitoring to generate energy savings Meter Reference Design enables secure smartphone transactions eak power demand reduction has been typically handled by installing energy storage devices in buildings or households and using them during times of peak power consumption, then recharging them during off-peak periods. However, this risks an overlap between storage device recharging periods, which can exacerbate peak power demand. Fujitsu Laboratories has developed peak power demand reduction technology for smart cities. Data, including the power consumed by each office and residence, as well as the usage patterns and charge levels of decentralised energy storage devices installed there, is collected in the cloud. By enabling cloud-based integrated control of energy storage devices, peak power demand can be effectively reduced, says the company as it allows for a recharging schedule to be planned which takes into consideration multiple versions of demand forecasts and user usage. During a test study it reduced the peak power demand of an office by approximately 10%. The technology tested forecast multi-pattern demand, classifying fluctuation data and patterns then narrowing down power demand fluctuation data to the patterns that are most likely to occur. A revised forecast for a consumption-recharging schedule is based on data that has been collected in the cloud about the usage patterns and the charge levels of energy storage devices. FujitSu lAborAtorieS 44 P ndustrial data communication company, INSYS icom, presented eDetect at this year’s E-world exhibition. The energy management system has data logging, analysis, visualisation, and consumption data optimisation required DIN EN 16001. For manufacturers, energy suppliers, businesses, and civil service departments, it can, claims the company, generate energy savings between 5 and 20% of the overall consumption. It can be used with the company’s industrial router, MoRoS, which receives energy consumption data from connected electricity meters. Integrated in the router is a Linux sandbox which provides an application for the intelligent pre-processing and transmission of all relevant data to the back end. Data is transferred via radio communication or any other IP network; the intervals can be individually adjusted. MoRoS supports various types of electricity meters and sensors. All required devices can be purchased as a bundle. For data visualisation and analysis, users sign up with the eDetect portal to access all relevant energy data and define the data they want to see as well as the layout. For example, peak loads can be located and matched to a particular process. For high energy savings, the company explains, processes can be precisely adjusted and optimised, monitored over a long term, and reports can be generated. inSyS iCom I F reescale Semiconductor and INSIDE Secure have announced a secure, pre-paid utility meter reference design with NFC connectivity. OEMs can use it to quickly and cost-effectively bring to market electricity meter products, says the semiconductor company. The reference design, based on the Freescale Kinetis MK30 microcontroller, provides the first NFC-based, pre-paid meter with the ability to securely reload energy credit balances. Secure pre-paid meters address the need for easy but secure payments with smartcard security mechanisms that have been proven in the banking industry. According to the companies, products based on this reference design are protected from fraud because they employ INSIDE Secure’s VaultIC security module and NFC technology to safely load energy credits from a smart card or an NFC-enabled phone. The VaultIC 460 and security module provides functions such as mutual authentication, verification and generation of certificates, encryption/decryption and managing secure storage of cryptographic keys. It is FIPS140-2 Level 3 ready. NFC connectivity is implemented using the MicroReadcontroller and Open NFC protocol stack. The system is powered by the Freescale MK30X256 32bit microcontroller built on the ARM Cortex-M4 core), which operates up to 100MHz with 1.25DMIPS/MHz. The firmware is based on Freescale’s MQX RTOS. www.epn-online.com/search?search_keyword=47356 April 2012 – epn issue n° 04 www.epn-online.com/search?search_keyword=47355 FreeSCAle SemiConDuCtor www.epn-online.com/search?search_keyword=47288 http://www.epn-online.com/search?search_keyword=47356 http://www.epn-online.com/search?search_keyword=47355 http://www.epn-online.com/search?search_keyword=47288
