Gridstream® updated for security In the latest release of its end-to-end smart grid platform Gridstream®, Landis+Gyr has made communication security a key priority for the data exchange between interoperable smart meters and head end system (HES) via power-line communications PLC. Over the past few years, as the scale of smart meter and smart grid deployments has reached a new level, regulators, utilities and their customers have become increasingly concerned about the security of information on smart metering systems. The challenge utilities are facing is how to secure the transfer of increasing amounts of smart metering data without compromising the privacy of end consumers, while maintaining the confidentiality, integrity and availability of this information to authorized parties. Landis+Gyr has been playing a leading role in driving the development of secure smart metering solutions and standards through its engagement with the IDIS Association and other leading manufacturers. To provide high levels of security for the data transfer and to prevent potentially sensitive data from getting into the wrong hands, Landis+Gyr has introduced encryption codes to its PLC-based devices, which account for 95% of the company’s smart meter market. IDIS compliant PLC and P2P meters are intrinsically “secure by design” through well-established DLMS-COSEM communication protocols. With the new Gridstream release, utilities will benefit from the combination of interoperable future-ready devices and a high level of communication security. The first Gridstream solution with encrypted data communications is currently undergoing field testing and will be deployed as a part of Landis+Gyr’s smart metering infrastructure for Elektrilevi, Estonia. Gridstream now also includes a HES device gateway, to support a broader range of metering devices by a single customer business 12
system. Most common use cases are available, such as scheduled and ad-hoc reading of billing profiles, load profiles and event logs, for third party and commercial and industrial smart meters connecting via the mobile networks. The Gridstream platform integrates the E450 series 3, Landis+Gyr’s latest IDIS-compliant smart residential meter. The company has redesigned the device from a production and reliability perspective, to facilitate mass deployments by utilities, as smart meter rollouts start to increase in scope ahead of 2020. The updated platform will be launched in the middle of the fourth quarter of 2014, following the testing and customer ramp-up phase. Gridstream evolution The integration of G3 PLC communication will be the next major step in Gridstream technology evolution towards smart grids and smart homes.
G3 specification uses OFDM PLC technology for data transmission and is primarily intended to function in CENELEC A band (3 – 95 kHz). G3 offers the possibility to migrate to a higher frequency range, resulting in up to 10 times more bandwidth. G3 PLC coexists with the already deployed PLAN PLC devices.
OFDM PLC technology is gaining reach across Europe thanks to its robust performance and optimized Total Cost of Ownership (TCO) per installed meter. Following the new IDIS package II (IP profile) incl. G3 PLC (due to be released in November 2014), Landis+Gyr will enhance its Gridstream end-to-end offering with the G3 PLC technology. Smooth migration path from the current to the next generation technology will ensure utility long-term investment protection.

Digitalizing existing power assets with the MV/LV Monitoring and Control Solution Reducing outage times and frequencies, mitigating the impact of increasing amounts of renewables on power quality, aging infrastructure and costs associated with smart grids and integration are just some of the challenges utilities are facing today. To address these Landis+Gyr has enhanced its smart grid portfolio with a cost-effective retrofit platform from newly acquired PowerSense designed to digitalize existing power distribution infrastructure. The MV/LV Monitoring and Control Solution comprises sensors that can be retrofitted onto medium and low voltage power cables, transformers and switch gear, and via integration of already installed electric devices in substations. The modular system’s features and benefits include automation and software controls that can locate, isolate and restore faults to reduce Customer Minutes Lost, by lowering System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI).
By implementing energy balancing and power data visualization utilities are able to reduce the network unbalances and maximize their revenue and the lifespan of energy assets. At strategic points power quality is monitored for any potential issues that might arise, while monitoring and control technology also allows the utility to visualize power flows, to ‘see’ where bottlenecks occur in the network. The solution is designed to manage the integration of renewable energy sources, such as 15

Photovoltaics, which can apply stress on cables and the network infrastructure because of their intermittency. In addition the system is able to carry out top precision energy theft detection. By implementing energy balancing and power data visualization utilities are able to reduce the network unbalances and maximize their revenue and the lifespan of energy assets. Some of the key solutions of the MV/LV Monitoring and Control portfolio include: The Advanced Smart Grid Terminal is a billing grade metering node with the smart grid functionality of MV/LV Monitoring and Control. Combined with the SmartCom RTU, the terminal aggregates and transmits real-time data to the utility’s high-level IT system, like SCADA, or other grid management IT platforms. Several applications can be included such as billing, integration of renewables and microgeneration, as well as streetlight functionality, enabling the utility to secure its investments and reduce operational costs. The Advanced Smart Grid Terminal cost-effectively meets DNOs’ smart grid requirements for secondary transformers, improving service quality and protecting existing energy management assets. The Smart Grid Device Integrator integrates existing and new smart grid devices, independent of their functionality, into the DNO’s SCADA or IT business system, enabling utilities to set up a cross-functional smart grid platform in substations which provides investment security and asset protection. In addition, the Smart Grid Device Integrator has 16 digital inputs and 8 digital outputs and can be combined with extra modules for additional functionalities. This provides utilities with the flexibility needed to extend, adapt and change the system in compliance with their individual smart grid strategies.

Warsaw goes smart Landis+Gyr will deliver smart meters and software solutions to a Polish utility RWE. RWE’s first installation of smart metering technology in Poland will focus on residential buildings in Warsaw. Deliveries have started in September and full system installation is scheduled for the end of 2014. Landis+Gyr will deliver its Gridstream® end-to-end solution, including 50,000 smart meters and Gridstream AIM software. The system will have an interface to RWE’s existing IT infrastructure and will help
22
optimize the customer’s asset management. Landis+Gyr will also provide billing services for a period of four years. RWE operates a number of companies in Poland, including RWE Polska and RWE Stoen Operator. RWE Polska, together with RWE East, is responsible for supporting the development of the Group in Poland. RWE Stoen Operator manages the Warsaw power network. The deal was preceded by a pilot where a number of providers showcased their technology; Landis+Gyr’s Polish team was able to convince the customer of their technology and win a public tender launched by RWE. “This is a significant milestone for Landis+Gyr,” says Andrzej Szymanski, Country Manager for Landis+Gyr Poland, “We are delighted to contribute to the development of smart metering in Poland with this project in the capital.” Landis+Gyr’s solution will enable the advancement of distributed generation which is to play a major role in the future energy market. Improving the system as a whole Between 2014 and 2019, RWE plans to channel 25 percent of its investments towards the rollout of smart infrastructure amounting to 420 million Polish Zloty (approximately 100 million Euros). In the first stage of the project, slated for completion by the end of 2014, RWE will install 25,000 smart meters in residential buildings in Warsaw; full project completion is scheduled for December 2015. RWE will also invest in its network, overhead high voltage lines, as well as in medium voltage cable lines in urban areas. There has been rapid smart metering development in Poland in the last years. The Polish National Energy Conservation Agency as well as the country’s three largest consumer organizations signed a declaration in June 2009 calling for the rapid introduction of the technology. “Implementation of the smart grid concept in the area of our operation will essentially improve the level of energy efficiency of the system as a whole,” says Agnieszka Nosal, Board Member of RWE Stoen Operator responsible for AMI investments. n 23

Naantalin Energia pilots Landis+Gyr’s new MV/LV Monitoring & Control solution Naantalin Energia, a small utility owned by the city of Naantali in south-west Finland, provides electricity to the municipality’s domestic and industrial electricity users – about 10,000 in total. As part of ongoing plans to enhance and improve network power quality and service, Naantalin Energia recently implemented, with Landis+Gyr, a pilot to demonstrate a PowerSense MV/LV Monitoring and Control solution. Sensors have been added to existing transformers in the field on the medium voltage (MV) network, so that the system is able to visualize the actual network status. The technology has also been installed inside a distribution substation for the utility to identify and detect the cause of failure and location. Such a level of detailed information enables distribution system operators (DSOs) to isolate defect areas more rapidly and also recover power supply to undamaged areas by supervising the remote controlled switches, all of which helps resolve outage times for customers. In addition the information received with the help of the Monitoring & Control solution will help utilities avoid overloading of the transformers. The end-to-end solution is realized through retrofitting sensors onto the existing medium and low voltage power cables, transformers and switch gears, allowing DSOs and utilities to prepare their assets for the future integration of distributed energy resources, electric vehicles and new power storage patterns. While all types of utilities will benefit from their power grids becoming digitalized and automated through sensor-based 24
hardware and intelligent software, for a small utility such as Naantalin Energia the value of this solution lies in its ability to identify and rectify issues that traditionally would require sending technicians and engineers out into the field, a costly endeavour in terms of both time and resources. “The modular solution can be retrofitted and scaled up, as part of utilities’ stepwise smart grid investment strategy,” explains Landis+Gyr’s Solution Consultant Sami Haapamäki. “Following the PowerSense acquisition, Landis+Gyr now provides the tools, not only to measure and monitor, but also to act, through automating the network,” he says. An additional benefit of the technology is its ability to monitor power quality on the low voltage (LV) side of the network, which will become increasingly important as consumption behavior changes and as more renewables are installed. To gather all of this data from smart meters – the nodes at the end of the LV network – would be extremely challenging, especially in high volume installations, which can run into tens of millions. Landis+Gyr’s MV/LV Monitoring and Control solution enables analysis of consumption behaviour in a condensed form, according to Haapamäki. n

Battery energy storage systems for high power applications Advanced energy storage systems are currently emerging as assets with potential for both network and generation applications within the grid network. Toshiba has recently developed a high power Battery Energy Storage System (BESS) for grid power quality and renewable energy power plant applications. The system, with 4MW of nominal power and 1MWh of energy capacity, will be installed in Italy in November 2014 on a wind farm of one of the major international Independent Power Producers Enel Green Power s.p.a. When integrated with the wind farm and connected to the grid network the BESS will smooth the intermittent power generated and make the renewable energy resource predictable. To achieve this, the system receives an hourly power schedule from the independent power producer’s main controller and, using the energy stored in the batteries, compensates for the gap between the power set point and the wind farm’s current generation. The advanced energy storage system’s controls ensure that power is injected into the grid within the desired range, taking into account the current status of the BESS, such as temperature of battery modules, the state of charge (SOC), charge/discharge rate, the characteristics of the inverters and the status of the grid. The effectiveness of the control strategy has been tested by using historic data from a wind farm. The BESS is designed to achieve a performance of 4C. C-rate is an important battery metric, measuring the capability of the battery module as a ratio between power and energy. For example, a 1kWh module can be charged/discharged at 4kW in 15’.

This performance is obtained thanks to Toshiba’s Super Charge ion Batteries (SCiB), which use lithium-titanate chemistry. The SCiB Lithium-Titanate technology provides a long life – over 10000 charge/discharge cycles – and performs safely even at temperatures as low as -30°. The batteries yield a high amount of usable energy over a wide range of SOC and also allow fast recharging, in approximately six minutes. n
