UK smart grid outfit Reactive Technologies has successfully demonstrated the transmission of data via the National Grid.
In what the company claimed to be a “world first”, Reactive Technologies sent and received data across the electricity network through subtle changes made to the grid frequency by modulating the power consumption of the transmitting devices.
Receivers, embedded in the plugs of devices, such as freezers, hot water tanks and air conditioning equipment, were programmed to detect these frequency changes.
Reactive said its Grid Data and Measurement System allows connected devices to share information and enables remote control and measurement of electrical assets across electricity networks.
The transmission of data could reduce energy bills for consumers who allow variations in the consumption of large appliances, it added.
The data provided by GDMS could also provide a clearer picture of how electricity is generated and consumed at the distribution network level.
DNOs would in turn use the information to balance networks becoming increasingly complex due to distributed and intermittent generation.
Reactive chief commercial officer Jens Madrian said: “GDMS can dramatically reduce the cost of creating large-scale smart grid networks allowing wider participation in demand-side response programmes by including domestic devices such as fridges, air conditioning systems and hot water tanks.”
National Grid director of UK System Operator Cordi O’Hara added: “This groundbreaking project has demonstrated the successful transmission of data through the electricity grid over long distances, critically passing through transformers and with a broad coverage.”
The project was funded via the UK Network Innovation Allowance fund. SSE was also involved in the trial.
