Modeling software is useful in analyzing new structures to increase the stability of the energy system, ensure effective and reliable distribution of energy, as well as the development of components that integrate alternative energy sources, such as nuclear fusion and renewable sources. The ability to imitate many physical phenomena in a unified modeling environment gives engineers a deeper understanding of how different components of the grid interact and affect each other.
For example, when developing various components of the grid infrastructure, such as transformers and transmission lines, analysis of a multi -polished electromagnetic field is important for ensuring the safety of people around and the environment. Understanding the thermal behavior, another phenomenon that includes several physicists, is equally necessary for the design of the components of the grid, where heat and thermal voltage dispersion can significantly affect the performance and life expectancy. Meanwhile, structural and acoustic modeling is used to predict and mitigate problems such as the vibration and noise of the transformer is an important practice to ensure the durability and reliability of the components of the grid.
Multiphysics Simulation It provides a critical understanding of complex interactions working in the Power Grid components, allowing engineers to almost test and optimize future grid designs.
An analysis of electric splitting and crown discharge is especially important for high -voltage lines, since such phenomena can jeopardize the performance of their insulation systems. Modeling allows developers to predict where such events will probably occur, improving the design of insulators and other components, where the goal is to minimize energy loss and material degradation.
As a real example, one leading manufacturer uses Comsol Multiphysix® modeling software software To develop magnetic ties, non -contact alternative to mechanical transmission, which provides power transmission without inherent constant contacts based on friction. Although the advantage of power transmission without friction means that magnetic couplings have discovered the use in a wide range of technologies, including naval windows, these systems should be carefully developed to avoid deterioration. Using the very non -linear hysteresis curves and using their own temperature dependences of the material for the magnetic load, the manufacturer’s developer team successfully used Multiphysics modeling to help prevent constant magnets until critical temperatures, which can cause irreversible demagnetization and threaten the reliability of structures. In addition, due to the diverse nature of the use of magnetic couplings, the company's engineers should be able to exchange the forms and materials of magnets to satisfy customer requirements without building expensive and laborious prototypes-create multiphysical modeling, modeling a powerful approach to obtaining data, providing virtual prototypes of their design, and establishing plans that lead to stability.
These examples show only some of the methods in which the combination of several interacting physics within the framework of one model can lead to successful modeling of real phenomena and thereby give an idea of current and future projects.

Improving reliability using digital twins and simulation applications
Engineering teams can also use modeling technology to create more effective, effective and stable energy networks by creating digital twins. The digital twin contains a high-quality description of the physical product, device or process-with microscopic to the macroscopic level-boat carefully reflects its real colleagueThe field for each application of the digital twin constantly receives information, providing an relevant and accurate representation.
With the help of this technology, the mesh operators and their equipment suppliers can predict which components will most likely fail, which will allow them to more effectively plan maintenance and replacement and thereby increase the reliability of the grid. Digital twins can be created for equipment, starting from power sources, including solar elements and wind turbines to energy distribution systems and battery energy storage.

The latest modeling and modeling technology provides energy and energy companies tools for creating digital twins in the form of autonomous modeling applications, which significantly increases the number of users who have access to advanced modeling technology. Including only the appropriate functionality in autonomous modeling, colleagues without the experience of modeling and modeling can use this technology without the need for management from a modeling specialist. In addition, the use of surrogate models controlled by data in the modeling applications allows you to almost intensively evaluate what would otherwise be laborious modeling, which means that the modeling technology can now be used in the real world.
Digital twins, in the form of autonomous applications, bring the power of modeling in a field where mesh operators can use information about real -time performance to ensure the reliability of the grid.
For example, one organization that works with local energy companies to analyze maintenance and equipment failure has created a user application based on the multiphysics model, which it has developed to predict cable breaks and increase the efficiency of disabilities. While engineers used modeling in laboratories for decades, cable failures in the field, and personnel are responsible for the elimination of problems at the spot. With this in mind, the engineer in the organization developed the Simulation application using the applied builder in Comsol Multiphysics®.

The application has the appropriate parameters that eliminate staff without modeling experience can easily change. Field techniques enter cable data and select the type a malfunction that changes the multiphysics model in real time, allowing the application to evaluate And the withdrawal of the data necessary for understanding the condition that led to an error. Then the application gives the registered potential and electric field, which leads technical specialists to an informed solution about whether they need to replace or repair the cable. After the successful deployment of the application, the engineer who developed it said: “The Simulation application plays a key role in cable maintenance. This makes the work of our field technicians more effective, allowing them to confidently evaluate and repair the shortcomings. ”
The routine physical tests of the mesh equipment cannot fully reflect the conditions or determine the types of failures in many situations, since it is necessary to take into account a large number of complex factors, such as the structure of the cable and material, impurities in the cable, voltage fluctuations, working conditions and the environment. As a result, the modeling turned out to be indispensable in many cases to collect accurate assessments of cable health – and now in the form of user applications, it is more accessible than when.
Generation of nuclear solutions
Modeling was also largely integrated into the design of various components related to nuclear industry. For example, modeling was used to help develop the generator circuit breakers (GCBS) for nuclear power plantsThe GCBS field should be reliable and capable of maintaining performance even after long periods of inaction. Comsol Multiphysics® The software can be used to improve the bearing capacity of GCBS, which can provide current protection and provide reliable electricity production.
The design of nuclear mergers such as Tokamaks also benefited from the use of modeling. These devices should be able to withstand high thermal fluxes and destruction in plasma. Comsol Multiphysics® It was used to help engineers predict the influence of these problems and come up with design solutions, such as adding a structural support system that can help reduce stress and survive difficult conditions.
Engineering grid tomorrow
The development of the next generation energy system is a complex and dynamic process that requires safe, reliable and affordable testing. Multiphysics Simulation technology can play an important role in future innovations for this industry, allowing engineers to anticipate and analyze the complex interactions that occur within these devices, simultaneously relying on the existing infrastructure to meet the requirements of modern consumption.
