Grid stability is a major concern in the U.S., especially after the Texas storm of February 2021. And while much has been made of AI-powered search tools, some of the biggest advancements in artificial intelligence are in the sciences, including renewable energy generation and distributed energy systems.
Sure, you can ask SearchGPT to help you lower your electricity bills — but can AI really help utility companies streamline energy distribution and avoid grid disruption?
Let’s take a look at how scientists are using AI with renewable technologies and grid management systems to improve decision-making and increase energy efficiency.
How Can AI Optimize Energy Storage and Distribution in Grids Powered by Renewable Energy Sources?
One of the biggest challenges in working towards a clean energy future is data analysis and optimization. All of the sustainable energy in the world won’t be enough if we don’t modernize our grid operations to distribute it in line with energy consumption.
Solar panels, wind turbines, and other renewable energy sources produce electricity on irregular schedules that don’t always match energy demand, and it can be difficult to do anything useful with solar and wind energy if we don’t have the capacity to store it.
AI solutions help address this problem by processing vast amounts of data in order to predict demand, stabilize the energy grid, and reduce downtime.
How Do AI Algorithms Ensure Efficient Energy Distribution?
AI-driven systems rely heavily on machine learning and data analytics to improve the way energy is distributed throughout the system. These tools can leverage historical data to anticipate periods of high or low demand, as well as real-time data from IoT (Internet of Things) devices like smart meters and smart appliances.
With predictive analytics, utility companies can better allocate energy to the electrical grid, relying on renewable energy resources when output is high and demand is low, and directing excess energy into storage systems when these facilities exist.
AI systems can also minimize outages by analyzing weather forecasts, temperature variations, and other external impacts on grid infrastructure.
What Is the Role of AI in Predicting Renewable Energy Production Variability?
Renewable energy technologies like wind and solar are inherently variable. The season, time of day, and real-time weather events can all impact how much energy these power systems produce. Unlike coal-fired power plants, you can’t just turn them on and off.
While renewable energy systems are key to sustainability, it’s an ongoing challenge for utility providers to keep the grid balanced in times of variable output and demand. Some utility companies use strategies like demand-side management (DSM) to encourage consumers to use energy during off-peak hours.
The U.S. Department of Energy has invested $10.5 billion into the Grid Resilience and Innovation Partnerships (GRIP) Program to “enhance grid flexibility and improve the resilience of the power system against extreme weather.”
These grants include support for AI systems that can predict output and demand more accurately and more efficiently than traditional grid management systems.
How Can AI Improve the Integration of Renewable Energy into Existing Power Grids?
Integrating renewable energy into existing power grids is a balancing act. According to a McKinsey report, “Grids were not originally set up for such a fast-paced energy system; their tools and processes were developed in a slower, less volatile world.”
With renewable energy, grid operators and other stakeholders must pay closer attention to real-time data to respond to minute-by-minute changes in the energy mix. Variations in frequency and voltage can result in outages and damage to grid infrastructure.AI-powered tools can process this real-time data more quickly than humans can read and interpret it, and even more efficiently than less powerful grid management tools. This means energy providers can use automation to stabilize the grid, reducing the likelihood of voltage and frequency variations getting out of control.
Can AI Technology Increase the Use of Energy Storage?
Another obstacle to wind and solar power is a lack of energy storage infrastructure. Just like the battery on an electric car, large-scale energy storage devices can store surplus power from the energy grid and return it to the distribution system later. For example, solar energy produced during the day could be stored for later use at night.
The DOE is funding research into long-duration energy storage (LDES) systems that would store energy for even longer periods and maximize renewable energy use.
Just as AI technology can help grid operators balance the electrical grid, it can also help them decide how much energy to store. AI tools can run simulations based on real-time usage and historical data to optimize the use of energy storage infrastructure.
Can AI Tools Help with Microgrid Management?
While a lot of the focus on AI with renewable technologies falls on the national grid, AI tools can help with small-scale grid management too. According to Intel, a microgrid is “a small-scale, local energy system that can disconnect from the traditional utility grid and operate independently” — especially during outages and emergencies.
Communities, businesses, and other organizations like colleges that invest in microgrids do so for the energy independence they offer, but face some of the same challenges as large-scale grid operators when it comes to balancing supply and demand. AI-driven grid management software can help with load balancing, cybersecurity, and more.
Wind and solar farms also face challenges connecting to large-scale grids. One study found that it takes “up to seven years to connect a new electricity generation project to the grid.” The Artificial Intelligence for Interconnection (AI4IX) aims to get through the backlog by automatically analyzing applications and identifying errors for review.
What Are the AI Techniques Used for Demand-Side Energy Management in Smart Grids?
A smart grid is one in which information can be exchanged across the network, allowing two-way communication between the utility provider and the consumer. For example, a consumer with solar panels might use net metering to sell power back to the grid.
Demand-side management refers to the practices energy providers use to influence consumer demand for electricity. This tends to fall into one of two categories:
- Load shifting encourages customers to shift their energy usage from periods of high demand to periods of low demand. For example, Amigo Energy’s Nights Free plan offers free electricity overnight in order to reduce daytime energy use.
- Load reduction involves helping customers reduce their energy consumption, either by using less energy, or by using more energy-efficient appliances.
AI tools can analyze various data points, including real-time demand, market data, and consumer behavior to develop effective demand-side management strategies. These might include time-of-use (TOU) pricing and vehicle-to-grid (V2G) systems that allow electric vehicle batteries to integrate more efficiently with the grid.
How Does AI Help to Detect and Mitigate Grid Instabilities?
Instabilities in the electrical grid can contribute to rolling blackouts and damage to the grid itself. AI helps to reduce the risk with automated fault and anomaly detection, as well as real-time monitoring for cybersecurity threats.
Instead of waiting for things to break down before fixing them, operators can take the initiative with predictive maintenance — anticipating when repairs will be needed based on weather conditions, wear and tear, and other factors. AI-powered tools can predict failures at power plants, transmission lines, and other points on the grid.
Adaptive grid management further supports grid operators with load forecasting, load shedding, and demand response management.
Are There Any Risks to Using AI with Renewable Energy Technologies for Grid Management?
AI technology has the potential to reduce grid instability and facilitate new approaches to renewable energy generation, such as agrivoltaics and space-based solar.
But as the Electric Power Research Institute (ESRI) explains, there are a few risks to consider. The first is giving too much decision-making power to AI. While AI tools can automate some aspects of grid management, grid operators still need to be ready to respond to extreme weather events and other emergency scenarios.
Another concern is data privacy. With more and more IoT devices collecting real-time usage data, it’s important that utility providers take care to anonymize data sets, and avoid disclosing information about individual energy consumers.
Finally, utilities and grid operators should ensure that AI tools don’t reinforce existing biases when allocating energy resources. A Georgetown University study found that the “socioeconomically disadvantaged take longer to get their power back on” after an outage, so it’s important to account for these biases when using AI for predictive maintenance or when determining which grid repairs to prioritize.
What Is the Role of AI in Reducing Energy Consumption?
Artificial intelligence can help utility companies and grid operators forecast renewable energy production and anticipate demand. This allows them to allocate electricity more efficiently and avoid outages due to supply chain issues or extreme weather events.
While individual consumers may not have the same AI-powered tools at their disposal, they can take the initiative by optimizing their own energy usage.
Some Internet of Energy (IoE) devices like smart meters and electric vehicle chargers may already incorporate real-time data analytics into their decision-making.
You also can switch to an energy supplier that offers a green energy plan and adjust your energy usage to align with peak solar or wind energy generation.
