Telecommunication networks are one of the most important factors for assuring a successful advanced metering infrastructure. The choice of the appropriate technology is not an easy decision for electricity distribution companies. Several questions arise.
To support the further growth and development of the Internet of Things (IoT) the mobile industry is developing and standardising a new class of GSM technologies focused on IoT, which is called Low Power Wide Area (LPWA) networks. These technologies enable the new IoT services to expand and be more competitive and hence that is why it has the following advantages.
The Internet of Things (IoT) is on everybody’s mind and analysts expect billions of connected devices in the upcoming years. In order to meet the increasing demands of products for consumers and IoT solutions for companies and business customers, new standards for transferring data have to be determined.
Traditional PLC-based smart metering solutions require the installation of PLC data concentrators in remote and unattended second tier substations. PLC Data concentrators handle communications with the different smart meters installed at consumer premises, consolidate the metering data and send it to the AMI management systems. (more…)
An amendment to Spanish law in 2006 requires all domestic electricity meters to include a means for accurate real-time meter readings, as well as remote manageability. These new electricity meters are called smart meters.
Together with some Teldat colleagues I recently attended the annual conference of EUTC (European Utilities Telecom Council), which brought together some of the main actors in the development of the Electric Grid, not only from Europe, but from all over the world.
The Grid is evolving at a huge pace to be able to cope with the enormous transformations that are taking place both in generation and consumption of electricity. The sessions provided much insight into how these changes are affecting the Electric Grid and what will need to be done in order to adapt to them.
The grid: electrical generation and consumption
Electrical generation is quickly becoming distributed through the development of new electrical plants (mostly renewables). In addition to having to control more generation points, the complexity greatly increases due to the variable output of many of these new plants.
As for electrical consumption, the Grid needs to cope with important upcoming challenges, such as the use of electric vehicles, which demand very large amounts of power while they charge. When correctly managed, the batteries on these vehicles could also serve as backup power in certain scenarios. Some consumers also use solar power to reduce their electricity consumption during the daytime. These are only some examples of the large changes in electricity consumption that are developing. Taking into account and adapting to this fast changing environment is vital to maintain the reliability of the Electrical Grid.
Teldat´s presentation at EUTC
The Conference sessions explored the innovations that are being applied in the Smart Grid in order to maintain and increase its reliability in the face of the increased complexity that is developing.
Various Conference sessions by all actors involved in Smart Grid deployments explored how to adapt and upgrade the Smart Grid’s communication network (the “Smart” part of the Grid) in order to cope with the new scenarios. The solutions that were studied included the transition from legacy SCADA networks to modern packet-based solutions. Current deployments were reviewed and new possibilities were proposed in order to ensure that the Electric Grid can remain stable and secure. In fact security was one of the main issues analyzed, given that the Electric Grid has become part of the critical infrastructure in developed nations, which rely on it for the wellbeing and everyday needs of their citizens. Sessions did not forget to explore how to make the whole Grid interconnect while blocking outside attacks which could compromise its integrity.
My presentation focused on the challenges and opportunities faced when bringing network connectivity to the outer parts of the electrical network: the smaller secondary substations. At these locations the DSO (Distribution System Operator) companies typically cannot provide network connectivity using their own infrastructure and must rely on public networks or deploy new networks in order to assure proper connectivity. Teldat can offer a solution for these cases based on its successful Regesta-PRO ER router line.
