EMPOWERING SMART GRIDS
Smart grids are revolutionising electricity distribution, but managing the myriad of new renewable energy sources is becoming an increasingly complex task for network operators due to the integration of Distributed Energy Resources (DERs). Here, Etienne Clauw, associate product line manager for remote telemetry units (RTUs) at Ovarro, explains why RTUs are proving essential for data analysis, management and decentralised network management in smart grids.
encompasses 5.5 million distribution lines and 600,000 miles of transmission lines. Its complexity arises from diverse energy sources, interconnections, varying state regulations and ageing infrastructure. That grid, like other traditional networks, will become more complex over the coming years as they adapt to the new era of smart technologies and renewable energy. Indeed, according to Recharge, the US has 36 “ready to go” renewable projects in the pipeline, which would double the nation’s renewables base and add a further 10,000 miles and 132 gigawatts (GW) of transmission capacity to the country’s electric grid.
T 68 Unlike traditional energy sources, the rise of
low-voltage and changeable DERs, like solar and wind farms, introduces new challenges to the electric grid. These DERs, dependent on factors like weather conditions, create network imbalances in frequencies and voltages, necessitating collaboration among a growing number of stakeholders.
In contrast to the centralised structure of traditional energy systems, smart grids are evolving toward a decentralised model. A study by the University of Peshawar, Internet of Energy: Opportunities, applications, architectures and challenges in smart industries published in Computers & Electrical Engineering describes a
he North American Power Grid, often dubbed the "largest machine" created by humans,
"decentralised topology with centralised management and interactive network," using Internet of Energy (IoE) technologies for upgrading and automating electricity infrastructures. However, smart grid data management faces challenges such as data aggregation quality, security, compliance control, common scope and efficiency of the management mechanism.
AN INTERACTIVE APPROACH JRC Smart Electricity Systems, the European Commission's in-house science service, advocates for an approach that considers the technological, social, business and environmental complexities of smart grids. This unified view aims to promote sustainability and resilience through model-based problem- solving - or, to paraphrase the study Blockchain in Smart Grids: A Review on Different Use Cases published in Sensors, optimising energy generation and consumption using smart systems that can monitor and interact with each other.
Accurate and consistent data monitoring and analysis are crucial for controlling and monitoring smart grid systems, including
