GridOS^® AEMS

An Advanced Energy Management System (AEMS) is a sophisticated software platform used primarily by transmission system operators to enhance the management, control, and optimization of electrical power systems. AEMS is designed to ensure the efficient, reliable, and secure operation of the transmission grid.

Advanced Energy Management Systems (AEMS) are designed to help electric utilities orchestrate the various parts of transmission grids. Here’s how they typically work:

1. Data Collection: AEMS gather data from various sources, including sensors, meters, and equipment within the energy network. This data includes information on energy consumption, production levels, weather conditions, and equipment status.
2. Monitoring and Analysis: The system continuously monitors the data to analyze energy usage patterns, detect anomalies, and identify opportunities for optimization. Advanced algorithms and machine learning techniques can be employed to assess historical data and predict future energy needs.
3. Optimization and Control: Based on the analysis, AEMS can make real-time decisions to optimize energy usage. This can involve adjusting the operation of equipment, switching energy sources, or implementing energy-saving measures. Automated controls can be used to ensure efficient energy distribution and consumption.
4. Integration with Renewable Energy Sources: AEMS can integrate renewable energy sources, such as solar and wind power, into the energy mix. This involves managing the variability and intermittency of these sources to ensure stable energy supply.
5. Demand Response: AEMS can implement demand response strategies, where energy consumption is adjusted in response to supply conditions or price signals. This helps balance supply and demand, and can reduce energy costs.
6. Reporting and Visualization: The system provides detailed reports and visualizations of energy performance, allowing users to track efficiency improvements and gain insights into energy management strategies.
7. User Interface: Users can interact with the AEMS through a user-friendly interface, where they can set preferences, receive alerts, and make manual adjustments if necessary.

Overall, Advanced Energy Management Systems (AEMS) aim to reduce energy costs, enhance reliability, and support sustainability goals by enabling the orchestration of the transmission grid.

Overall, an Advanced Energy Management System plays a pivotal role in enabling the modern electric grid to operate more efficiently, integrate diverse energy sources, and deliver reliable electricity to consumers.

Advanced Energy Management Systems can resolve many challenges transmission grids experience, including renewables integration, grid congestion and more. Here are a few of these challenges:

Key challenges addressed by Advanced Energy Management Systems:
• Integration of Renewable Energy: The increasing integration of intermittent renewable energy sources, such as wind and solar, poses challenges in maintaining grid stability and reliability. These sources can cause fluctuations in power supply, requiring advanced management and control strategies.
• Aging Infrastructure: Many transmission grids are operating with infrastructure that is several decades old. This aging equipment can lead to increased maintenance costs and a higher likelihood of failures, impacting grid reliability.
• Grid Congestion: As demand for electricity grows, certain parts of the transmission grid may experience congestion, leading to inefficiencies and increased costs. Managing congestion requires effective planning and investment in grid upgrades.
• Regulatory and Policy Challenges: Transmission grids must navigate a complex landscape of regulations and policies that can vary significantly across regions. Examples include the United States’ FERC 881 and the European Union’s ENTSO-E mandates. Aligning grid operations with regulatory requirements can be challenging and may impact investment and operational decisions.
• Demand Variability: Enormous fluctuations in electricity demand, driven by factors such as weather, economic activity, and the adoption of electric vehicles, require advanced demand forecasting and management strategies to ensure grid stability.
• Climate Change and Extreme Weather: Increasingly severe weather events and changing climate patterns pose risks to transmission grid infrastructure and operations, calling for better resilience planning and recovery measures.

Advanced Energy Management Systems offer many benefits to electric utilities, including better reliability, improved renewables integration, and more. Here are some benefits of Advanced Energy Management Systems for electric utilities:

Dynamic Line Rating (DLR) is an essential capability of AEMS. It involves assessing the capacity of transmission power grid lines in relation to given weather and environmental factors. Transmission grid utilities can use this information to ensure their existing infrastructure is being used at maximum capacity at all times, and that no energy is wasted. Calculating transmission line ratings is required by FERC 881.

GE Vernova’s Advanced Energy Management System offers a software- and analytics-based approach to line ratings called Digital Dynamic Line Rating (DDLR). This capability makes the process easier, faster, and more cost-effective than the traditional hardware sensor-based approach.
