An algorithm for heating hot water tanks

While constant progress is being made in the area of renewable energy generation, it is still a struggle to find ways of storing and reusing surplus power. Wind and solar, in particular, tend to lose the excess power they generate because two-thirds of installations are connected to low-voltage networks that are not designed to carry energy over long distances.Researchers have been able to develop an algorithm that identifies and forecasts a tank’s consumption according to the surplus solar power in the district.As a result, the challenge for researchers is how to use the surplus power on a local (district) level. Now, a team from EDF’s R&D division has come up with an innovative solution: use the power to heat France’s 12 million hot water tanks.Tailored servicesUsing the tariff signal, the surplus energy could be used to heat hot water tanks at virtually no cost. The absorption capacity of each tank is required to transfer the power – which is where Linky smart meters come in: they provide data on a household’s electricity load profile. Using this information, researchers have been able to develop an algorithm that identifies and forecasts a tank’s consumption according to the surplus solar power in the district. The algorithm could also be used to develop tailored services for customers based on their usage and needs, in order to maximize the use of local renewable energy sources.The Nice Grid smart solar district, which has been under development in Carros in the south of France since 2011, has been chosen as the test site for this ingenious system. After testing, the solution could be rolled out to EDF customers to help better meet their energy needs and make the most of every gust of wind and ray of sunshine.To go further
