Last February, Google announced they have trained an Artificial Intelligence system to predict wind power output 36 hours in advance, by using DeepMind’s machine learning algorithms to forecast the energy output of Google wind farms located in the U.S.
Although Eolic farms have become an affordable solution for clean energy generation, its technology has been limited to work at its full potential due to the significant variability of the wind, making Eolic Energy Generation in disadvantage compared to other power generation solutions.
This announcement comes a year after Google’s DeepMind implemented machine learning algorithms on its fleet of wind farms in the central United States. With 700 megawatts of wind power capacity installed, these wind farms can produce enough power to supply a medium-sized city.
“Using a neural network trained on widely available weather forecasts and historical turbine data, we configured the DeepMind system to predict wind power output 36 hours ahead of actual generation. Based on these predictions, our model recommends how to make optimal hourly delivery commitments to the power grid a full day in advance. This is important because energy sources that can be scheduled (i.e. can deliver a set amount of electricity at a set time) are often more valuable to the grid,” says Google.
According to the DeepMind, their software has considerably imporved the reliability of wind energy, increasing the power output by 20 percent over the baseline of farms where no such time-based predictions are being implemented. Yet we don’t know what that value is in monetary terms or in terms of energy generation.
“Operating our business in an environmentally sustainable way has been a core value from the beginning, and we’re always working on new ideas to make sustainability a reality,” says Google on an article published back in 2017 were they ensure they will reach 100 percent of renewable energy for their global operations — including both data centers and offices.
Google seems to demonstrate that it is fully committed to the alleviation of climate change, consolidating its position as one of the most important companies in the world leader in the battle against climate change.
DeepMind is an Artificial Intelligence lab based in London which was acquired by Google in 2014 for a reported value of £400 million.
