FEATURE MONITORING & METERING


Efficient monitoring solution for reducing energy consumption


IHM Pacific and Andrea Informatique have collaborated to develop a new electricity metering solution based on Semtech Corporation’s LoRa devices and the LoRaWAN protocol


D


eployments of the metering solution have been ongoing for


over a year and are increasing in New Caledonia and some parts of the Pacific and Europe. “Semtech’s LoRa devices and the


LoRaWAN protocol allowed us to create metering solutions that offer significant advantages for sustainable, cost saving utility metering,” said Francois Ista, CEO of IHM Pacific. “Real-time data on energy use


provided by our LoRaWAN-connected meters enable customers to closely monitor usage trends. By addressing wasteful habits to increase energy efficiency, our customers typically receive a return on investment (ROI) in three months to six months following deployment of up to 26 per cent.”

electricity meters leverage Semtech’s LoRa devices and the LoRaWAN protocol to offer significant improvements over traditional metering solutions in both applications of electricity metering for utilities and sub metering. LoRa-based smart meters do not require additional external cabling (IP, RS485 or pulse network cabling). This allows for greater ease of installation with solutions to quickly deploy in two DIN rails, a standard mount for meter equipment racks. Simplified deployment significantly reduces the cost of installation for the customer, which typically accounts for 40 per cent of the total cost of ownership. In addition, the reliable usage data


provided by LoRaWAN-based solutions enable customers to understand their


energy consumption in real time. Due to the remote monitoring of electrical consumption and a vast collection of measurement data including the active energy consumed and produced to detect abnormal consumption trends and adjust usage rates, customers usually see up to 26 per cent reduction in power consumption within three to six months of deployment.

Ensuring reliable communication in smart grids


Austrian energy tech company, cyberGRID, is playing an important role in the optimisation of distribution grid operation, as demonstrated in project InteGrid


S


mart metering is a crucial feature in modern power networks. It allows


flexibility providers to keep track of energy utilisation through data collection. A growing number of energy players are seeking this service because, with smart metering, usage rates can be analysed: valuable information which can be monetised on energy markets. Thanks to InteGrid, a project


supported by the EU’s Horizon 2020 programme, Distribution system operators (DSOs) can now assume a new role as enablers of cutting-edge energy services, increasing the reliability, efficiency and hosting capacity of distribution grids. These services include the grid market


hub, an IT platform where several technical/non-technical tools can be provided, such as energy services to be offered to end users and generation or flexibility services offered to network operators. The grid market hub as a central point of information can tackle challenges concerning secure and

reliable information by providing smart metering data to qualified receivers in a short time. In addition, the grid market hub also


allows businesses to offer forecasting load services and provide these to partners or to the TSO. Here, cyberGRID’s ICT-solution serves as an interface between the flexibility provider and the DSO to easily exchange power. Another highly valuable tool developed


and demonstrated in InteGrid is the traffic light system for DSOs to manage the integration of flexibilities for ancillary service markets. DSOs will introduce temporal limitations on market activities in stressed grid sections, dynamically adapting to the current and forecast load on the network elements. “Increased feed-in from renewable


energy sources necessitates an interconnected planning of the grid with smart technologies. cyberGRID’s IT-platform serves as an interface to seamlessly exchange active power between the flexibility provider and the


DSO”, Christoph Gutschi, cyberGRID’s senior project manager clarifies. Practical innovation has been created


with regards to the management of flexibilities from wastewater treatment plants. A tool has been developed and tested in the framework of InteGrid to help the internal energy optimisation to reduce energy costs of the facilities. Furthermore, a method to integrate


wastewater treatment plants into Virtual Power Plants (VPPs) was developed. Project demonstrators were successfully installed, and real data was gathered from the field, all of which confirm the usefulness of this project’s innovation. This is interesting from a replicability perspective, as thousands of wastewater treatment plants can provide flexibilities. Their integration into VPPs, thus, represent a cost-friendly source of flexibility. This project has received funding from


the European Union’s Horizon 2020 research and Innovation Programme.
