How Local Electricity Networks Can Cope With Charging Clusters Of EVs: My Electric Avenue

Published

on

My Electric Avenue is a three-year Ofgem-funded project that has been carrying out trials to discover the impact that charging clusters of electric vehicles (EVs) might have on local electricity networks at peak times.

As sales of plug-in cars continue to rise, and as EVs gain ever-larger battery capacities, the trial results show that collaborative action will be needed by the energy and automotive industries to support the growing demand for EV charging in some areas of the UK, and that some of the smart solutions that the industry is developing can help.

My Electric Avenue has been hosted by Scottish and Southern Energy Power Distribution and led by EA Technology. It has been funded through Ofgem’s Low Carbon Networks Fund, with in-kind contribution from key partners. The project has analysed the various kinds of low voltage networks in the UK and four types are expected to experience issues due to the uptake of EVs at differing penetration levels.

By recruiting clusters of neighbours around the country who drove Nissan LEAF electric cars for 18 months, the project teams aimed to mimic a future scenario where many people in an area choose to use a pure electric vehicle or plug-in hybrid electric vehicle (PHEV).

The results, which come at a time when sales of plug-in cars have increased by 716% over the past two years, show that across Britain 32% of low voltage (LV) feeders (312,000 circuits) will require intervention when 40% – 70% of customers have EVs, based on 3.5 kW (16 amp) charging. Susceptible networks are typically characterised by available capacity of less than 1.5 kW per customer.

Traditionally, these findings would mean the replacement of underground cables in the public highway, however My Electric Avenue has been trialling a lower cost solution to this in the form of ‘Esprit’. Esprit is an innovative piece of technology that can control the charging of EVs if the local electricity grid reaches a certain level of demand. By incorporating Esprit into networks, the project is the first real-life trial that has directly controlled domestic EV charging to prevent underground cables, overhead lines and substations being potentially overloaded.

Forecasts suggest that Esprit could save around £2.2 billion of reinforcement costs up to 2050. However, for this solution to work, car manufacturers and the energy industry will need to work together more closely.

My Electric Avenue is now coming to an end and it is disseminating its findings so that energy companies, car manufacturers and others can learn from the project.

My Electric Avenue Project Director, Dave Roberts from EA Technology, comments: “The automotive sector has well established and effective communication channels to discuss industry issues. However, historically there has not been much cross-sector communication between the automotive and energy industries. My Electric Avenue has brought these two sectors together and has started dialogue, and this needs to develop further as vehicle manufacturers announce plans for increasing numbers of higher performance plug-in vehicles.”

Stewart Reid, Head of Asset Management and Innovation at Scottish and Southern Energy Power Distribution adds: “The project has been invaluable in showing us what challenges we are likely to face in the near future as more and more customers adopt EVs. It’s also demonstrated that there is a solution which is capable of helping us overcome these challenges before they affect our customers. With new vehicles due to place even greater demands on our networks, we are conscious of the need for both ourselves and the automotive industry to share our learning, challenges and innovations with one another. We are excited at this prospect, which will allow the decarbonisation of our respective industries to continue at pace.”

Olivier Paturet, General Manager – Zero Emission Strategy, Nissan Europe said: “The all-electric Nissan LEAF is a pioneer in its own right and we’re delighted that it has played such a major role in My Electric Avenue’s ground-breaking research. Not only has My Electric Avenue provided us with a greater understanding of the impacts of electric vehicle charging on local grids, but it has also given us a clear vision of what the streets of the future may look like.

“EV sales are increasing at a phenomenal rate in the UK and wider Europe and it’s vital that automakers continue to work closely with the energy industry to progress the EV movement. Nissan is already heavily involved in the development of ‘smart grid’ technologies that will allow EV drivers to proactively manage their electricity use at home and we will be making further announcements on this during the coming months.”

There has been a wide variety of learning outcomes from My Electric Avenue, ranging from its successful customer engagement approach to assessing EV drivers’ acceptability of having their charging externally controlled. All the learning is published on the project’s website.

My Electric Avenue presented the results from the project, and facilitated a discussion about how the UK can deal with this issue going forward, at a ‘Finale’ event in partnership with the event’s host, the Institution of Mechanical Engineers, in London on 3 December 2015.

7 New Technologies That Could Radically Change Our Energy Consumption

Most of our focus on technological development to lessen our environmental impact has been focused on cleaner, more efficient methods of generating electricity. The cost of solar energy production, for example, is slated to fall more than 75 percent between 2010 and 2020.

This is a massive step forward, and it’s good that engineers and researchers are working for even more advancements in this area. But what about technologies that reduce the amount of energy we demand in the first place?

Though it doesn’t get as much attention in the press, we’re making tremendous progress in this area, too.

New Technologies to Watch

These are some of the top emerging technologies that have the power to reduce our energy demands:

  1. Self-driving cars. Self-driving cars are still in development, but they’re already being hailed as potential ways to eliminate a number of problems on the road, including the epidemic of distracted driving ironically driven by other new technologies. However, even autonomous vehicle proponents often miss the tremendous energy savings that self-driving cars could have on the world. With a fleet of autonomous vehicles at our beck and call, consumers will spend less time driving themselves and more time carpooling, dramatically reducing overall fuel consumption once it’s fully adopted.
  2. Magnetocaloric tech. The magnetocaloric effect isn’t exactly new—it was actually discovered in 1881—but it’s only recently being studied and applied to commercial appliances. Essentially, this technology relies on changing magnetic fields to produce a cooling effect, which could be used in refrigerators and air conditioners to significantly reduce the amount of electricity required.
  3. New types of insulation. Insulation is the best asset we have to keep our homes thermoregulated; they keep cold or warm air in (depending on the season) and keep warm or cold air out (again, depending on the season). New insulation technology has the power to improve this efficiency many times over, decreasing our need for heating and cooling entirely. For example, some new automated sealing technologies can seal gaps between 0.5 inches wide and the width of a human hair.
  4. Better lights. Fluorescent bulbs were a dramatic improvement over incandescent bulbs, and LEDs were a dramatic improvement over fluorescent bulbs—but the improvements may not end there. Scientists are currently researching even better types of light bulbs, and more efficient applications of LEDs while they’re at it.
  5. Better heat pumps. Heat pumps are built to transfer heat from one location to another, and can be used to efficiently manage temperatures—keeping homes warm while requiring less energy expenditure. For example, some heat pumps are built for residential heating and cooling, while others are being used to make more efficient appliances, like dryers.
  6. The internet of things. The internet of things and “smart” devices is another development that can significantly reduce our energy demands. For example, “smart” windows may be able to respond dynamically to changing light conditions to heat or cool the house more efficiently, and “smart” refrigerators may be able to respond dynamically to new conditions. There are several reasons for this improvement. First, smart devices automate things, so it’s easier to control your energy consumption. Second, they track your consumption patterns, so it’s easier to conceptualize your impact. Third, they’re often designed with efficiency in mind from the beginning, reducing energy demands, even without the high-tech interfaces.
  7. Machine learning. Machine learning and artificial intelligence (AI) technologies have the power to improve almost every other item on this list. By studying consumer patterns and recommending new strategies, or automatically controlling certain features, machine learning algorithms have the power to fundamentally change how we use energy in our homes and businesses.

Making the Investment

All technologies need time, money, and consumer acceptance to be developed. Fortunately, a growing number of consumers are becoming enthusiastic about finding new ways to reduce their energy consumption and overall environmental impact. As long as we keep making the investment, our tools to create cleaner energy and demand less energy in the first place should have a massive positive effect on our environment—and even our daily lives.
