COMSOL Day: Electric Power

The COMSOL Multiphysics^® software is widely used in the energy sector to model and simulate electric power systems that involve tightly coupled electrical, thermal, and physical phenomena. The software provides a comprehensive set of features for the research, design, and optimization of grid-scale energy storage systems, high-voltage cables, and other critical power system components, while also enabling detailed analysis of heat transfer and thermal management effects.

Beyond physics-based modeling, COMSOL Multiphysics^® supports the creation of standalone simulation apps, digital twins, and surrogate models, allowing simulation expertise to be shared across broader teams and integrated into engineering workflows.

Attend this session to get an overview of how multiphysics models and simulation capabilities are being used for engineering tasks in the energy sector and to receive a high-level introduction to the key topics that will be explored throughout this COMSOL Day.

Grid-scale energy storage plays a critical role in enabling reliable, flexible, and resilient energy systems. Technologies such as battery energy storage systems (BESS), fuel cells, and electrolyzers are increasingly deployed to balance supply and demand, integrate renewable energy sources, and support grid stability. Designing and operating these systems requires detailed insight into coupled electrochemical, thermal, mechanical, and fluid dynamic processes over multiple scales.

The COMSOL Multiphysics^® software provides a complete simulation framework for modeling grid-scale energy storage technologies. Using multiphysics models, engineers and scientists can study electrochemical performance, heat generation and thermal management, species transport, fluid flow, and degradation mechanisms in battery systems as well as in fuel cell and electrolyzer stacks. These models enable investigation of operating conditions, system-level integration, and performance optimization for stationary energy storage applications.

In this session, you will gain an overview of how multiphysics modeling and simulation is used to support the design, analysis, and optimization of grid-scale energy storage systems, with examples spanning batteries, fuel cells, and electrolyzers for energy sector applications.

As the world moves toward sustainable energy, the need to transfer electric power over long distances from areas of energy production to consumption is increasing. Power transmission systems may involve high-voltage direct current (HVDC) submarine cables but also terrestrial cables and conventional AC transmission lines. The COMSOL Multiphysics^® software is frequently used to model such systems.

The AC/DC Module add-on product, in particular, comes with a unique feature set that enables engineers and scientists to optimize high-voltage alternating current (HVAC) and HVDC cable systems for minimum loss, low cost, and maximum durability. It also provides built-in functionality for calculating admittance, impedance, voltage compensation, and bio-effects from AC transmission lines.

Join this session to get an introduction to modeling capacitive, inductive, and thermal effects in industrial-scale cables and transmission lines.

The COMSOL Multiphysics^® software can be used for development in a wide range of engineering applications. In the development of energy storage systems, electrical machines, and power system components, the software is especially useful for understanding and designing thermal management systems. Its unique multiphysics modeling capabilities make it ideal for studying heat transfer and heat generation in combination with electromagnetic fields and currents, nonisothermal flow, stresses and strains due to thermal expansion, and electrochemical processes in batteries and fuel cells.

In this session, you will get an overview of the functionality in COMSOL Multiphysics^® that can be used to understand and design thermal management systems.

Modeling and simulation of electromagnetic pulses, electrostatic discharges, and related phenomena plays an important role in the product development of power system components, enabling engineers to understand underlying processes, develop innovative solutions, and reduce costs associated with experimental testing and prototyping.

The Electric Discharge Module, a newly released add-on product to the COMSOL Multiphysics^® software, provides functionality for analyzing and predicting electric discharge behavior in gases, liquids, and solid dielectrics. This includes the study of streamer, corona, dielectric barrier, and arc discharges. Fully compatible with other COMSOL products for electromagnetics, structural mechanics, and fluid dynamics, this module enables the exploration of multiphysics effects that are often associated with electric discharges.
