The Impact of AI on Managing Enterprise-Level DERs

Distributed Energy Resources (DERs) are often heralded as the next revolution in electricity generation, offering a significant means to cut greenhouse gas emissions and combat climate change. However, the transition to DERs is not a future concept—it's already unfolding. In 2022, Forbes reported that solar installations in the U.S. had surpassed 120 GW, with about half of this capacity being distributed. Additionally, close to 12 GW of battery storage had been connected to the grid. That same year, the Department of Energy forecasted that over $110 billion worth of DERs would be deployed nationwide by 2025.

Distributed Energy Resource Management Systems (DERMS) facilitate integrating, controlling, and optimizing DERs such as solar panels, wind turbines, and energy storage solutions across the power grid. Integrating Artificial Intelligence into DERMS is critical in managing these resources when scaling up to millions of DERs to enhance efficiency, sustainability, and operational capability at an enterprise level.

Superiority of AI-Enabled DERMS for Scalable Operations

The proliferation of DERs has introduced complexity and variability that traditional systems need to be equipped to handle efficiently. 

One of the foundational strengths of AI-enabled DERMS is the ability to process and analyze large volumes of data from a myriad of DERs across the grid. Here are reasons why this capability is critical:

• Real-time Monitoring: Continuous, real-time monitoring of DER performance, grid conditions, and energy demand allows for immediate responses to changes, ensuring grid stability.
• Predictive Analytics: AI algorithms can forecast energy production from renewable sources and predict demand patterns, enabling proactive grid management to balance supply and demand effectively.

Unlike traditional systems, which (at very best) operate based on fixed algorithms and parameters, AI-enabled DERMS are dynamic learning systems. They improve over time by:

• Adapting to New Conditions: As AI systems process more data, they refine their algorithms to predict better and manage grid dynamics, accommodating new DERs and changing consumption patterns.
• Optimizing Performance: Continuous learning enables AI-driven DERMS to optimize energy distribution, improve the efficiency of renewable energy utilization, and reduce wastage through more accurate forecasting and better decision-making processes.

The diverse nature of DERs, each with its own operational characteristics and connectivity protocols, poses a significant challenge for grid management. AI-enabled DERMS excel in:

• Responding to Disturbances: AI systems can quickly identify and respond to grid disturbances, rerouting power or adjusting DER outputs to maintain grid integrity.

AI in Large-Scale Energy Forecasting and Management

The capability of AI to analyze vast arrays of historical and real-time data from millions of DERs allows for unprecedented accuracy in predicting energy demand and generation patterns. 

Traditional forecasting methods, which often rely on historical trends and simpler statistical models, cannot adequately account for the variability and complexity introduced by renewable energy sources like solar and wind. AI algorithms, however, can digest complex datasets, including weather patterns, seasonal variations, and user behavior, to make highly accurate predictions about energy generation and demand.

Furthermore, the accurate forecasts AI provides are crucial for dynamic load balancing. This process involves adjusting the energy supply from various sources in real time to meet the fluctuating demand without overloading the grid. By predicting peak times and potential energy surges, AI enables grid operators to manage resources dynamically, ensuring a stable and reliable energy supply. This capability is vital because more intermittent, renewable energy is injected into the grid.

Automated Decision-Making for Efficiency at Scale

The automation capabilities of AI within DERMS represent a transformative shift in how energy resources are dispatched and controlled. 

AI enables the real-time, automated dispatch and control of DERs, essential for maintaining grid stability and efficiency. AI algorithms can rapidly decide when and where to dispatch energy resources by analyzing data from various sources. This includes turning renewable energy sources on or off, managing storage systems, and controlling demand response events. Automating these processes reduces the need for manual intervention, making the management of DERs more efficient and less prone to error.

As the number and variety of DERs on the grid continue to grow, AI's automation capabilities enable DERMS to scale up without a proportional increase in complexity or operational challenges. This scalability ensures that the grid can adapt quickly and efficiently as new technologies emerge and consumer behavior changes. This adaptability is crucial for ensuring the long-term sustainability and resilience of the energy grid.

Stabilizing the Grid with AI

Integrating renewable energy sources is pivotal for meeting sustainability goals, but it introduces challenges due to the variability of these sources. The objective is to manage these fluctuations effectively to ensure the electricity grid's reliability.

A significant hurdle with renewables such as solar and wind is their reliance on weather conditions, leading to unpredictable energy generation. We can use AI's advanced algorithms to analyze historical weather data and energy production patterns accurately to predict these fluctuations. This predictive capability enables grid operators to anticipate high or low energy production periods, improving resource management and grid stability.

The proactive nature of AI allows for swift adjustments in response to changing conditions, thereby reducing the risk of power outages and ensuring a consistent electricity supply. By optimizing the integration and utilization of Distributed Energy Resources (DERs), AI contributes to building a more resilient grid.

Moreover, AI-driven insights and automation offer significant benefits in terms of operational efficiency, cost reduction in grid management, and enhanced service reliability for consumers. Utilities can leverage AI to adapt to current conditions and plan for future scenarios, including necessary infrastructure investments to accommodate the increasing share of renewable energy sources.

A stable grid capable of accommodating a higher percentage of renewable energy contributes to the overarching goal of reducing greenhouse gas emissions and transitioning towards more sustainable, decentralized, and consumer-centric energy systems.

AI-Driven Optimization of Demand Response and Maintenance

In managing millions of Distributed Energy Resources (DERs), AI's capabilities extend beyond grid stability to optimize demand response strategies and improve the maintenance and longevity of DERs. 

Studies by institutions like the Electric Power Research Institute (EPRI) have shown that AI-enabled demand response programs can significantly shift peak load. Demand response programs are designed to manage consumers' energy consumption during peak usage times to reduce strain on the grid. AI enhances these programs by:

• Predicting Peak Usage: Using historical data and real-time analytics, AI algorithms can accurately forecast periods of high energy demand. This predictive capability allows utilities to plan demand response events more effectively and precisely.
• Facilitating Energy Redistribution: AI enables dynamic adjustments to energy distribution during peak times. It can automatically adjust DER operations, such as reducing energy consumption in industrial processes or temporarily increasing the output from energy storage systems, to balance the grid without compromising service reliability.

Predictive Maintenance for DERs

Predictive maintenance involves using AI to analyze data from DERs to predict potential failures before they occur. This approach has several benefits:

• Reducing Downtime: Texas has recognized the importance of DERs in enhancing grid reliability and resilience, particularly in the wake of extreme weather events, and is actively working on expanding and integrating DERs within its energy system. One notable initiative in the state is expanding an 80 MW distributed energy resource pilot aimed at harnessing flexible resources to improve grid reliability. Finally, between 2000 and 2022, Texas experienced the highest number of power outage events affecting at least 50,000 customers, followed by California and Michigan. With AI-enabled DERMS, utilities in Texas and nationwide can schedule repairs for DERs before a failure occurs by predicting when maintenance is needed, significantly reducing unplanned downtime. This ensures a continuous and reliable energy supply.
