A £2 million machine-learning tool is creating a ‘Matrix-like’ simulation of the South East’s electricity network, that could unlock energy capacity equivalent to 1,371 new rapid-electric car chargers by 2028.
UK Power Networks’ Envision project is simulating how power is flowing through its networks across London, the South and South East of England. From this data-led approach providing better ‘visibility’ of everything that is happening across hundreds of thousands of miles of network, the company says it will be able to run the network more efficiently and safely to allow more low-carbon technologies like EV chargers to connect.
Experts forecast Envision could release almost 70MW of electricity capacity by 2028, creating more space for EV chargers or low-carbon heat pumps. This means engineers won’t need to physically upgrade the network to release capacity, leading to significant cost and time savings: estimated at up to £4 million in total over the next five years.
The company says connecting more EV chargers and electric heat pumps is critical to tackling the climate crisis and reaching the UK’s ‘Net Zero’ carbon emissions target by 2050. There are currently more than 150,000 electric cars and 20,000 heat pumps in the areas served by UK Power Networks, but its analysis forecasts over 2.6 million electric vehicles and 712,000 heat pumps by 2030. These need ‘space’ on the electricity network, so quickly and efficiently unlocking more capacity is a vital part of the network operator’s strategy.
Envision is building new predictive models which combine UK Power Networks’ data with external and real-time data from monitoring devices connected to substations. The machine-learning algorithm is designed to create a simulation of the electrical ‘load’ in specific areas and expand it across the entire network. Engineers will compare the simulation to real-life physical monitors, feeding the software more and better data over time so the algorithm gets more accurate.
Ian Cameron, head of customer services and innovation at UK Power Networks, said: “Our customers rightly expect us to do everything we can to make the switch to electric cars and low-carbon heating as affordable as possible. Through Envision, we’re thinking outside the box and re-imagining traditional ways of working, to make it happen.”
Simone Torino, head of product and business development at CKDelta, which is collaborating on the project, said: “The aim of the Envision model is to generate a ‘virtual sensing network’ that uses advanced data capabilities and machine learning to simulate the behaviour of the network at scale, accurately estimating changing network load profiles. In a world where the uptake of new distributed energy resources and the increasing electrification of transport are impacting electrical demand and distribution network constraints like never before, having this type of modelling and predictive analytics capabilities is a game changer for the utilities sector and has potential to reshape how we approach demand and supply in other sectors such as transport.”
