Sustainable energy and transformers: key technologies to drive the energy transition

As the global demand for sustainable energy continues to grow, renewable energy sources such as solar and wind are becoming an increasingly important part of the power system. However, integrating these decentralised energy resources into the existing grid faces a number of challenges, one of which is the role and performance of transformers. This paper will explore the relationship between sustainable energy and transformers and discuss how transformer design can be optimised to drive the energy transition.

The challenge of sustainable energy for power systems: The volatility and fragmentation of renewable energy sources is one of the main challenges facing power systems today. The availability of solar and wind energy is limited by weather conditions, leading to volatility in electricity. In addition, these energy resources are often located far from consumption centres and need to be transported over long distances. The efficient integration of sustainable energy sources into power systems to ensure a stable supply of energy has therefore become a key issue.

The role of transformers in sustainable energy integration: Transformers play an important role in power systems, where they are used for step-up and step-down voltage as well as for the transmission and distribution of electrical energy. In sustainable energy integration, transformers need to be adapted to the characteristics of new energy sources to achieve efficient energy conversion and transmission. Optimising transformer design can reduce energy losses and increase the stability and reliability of the power system.

The challenge of optimising transformer design for sustainable energy: Integrating sustainable energy sources into power systems requires consideration of the following aspects:

  1. Large-scale power transmission: Solar and wind energy resources are often distributed over large geographical areas and need to be transmitted over long distances. The design of high-capacity and high-efficiency transformers is therefore key to achieving large-scale energy transmission.
  2. Stability of fluctuating energy sources: The volatility of renewable energy sources has an impact on the stability of power systems. Transformers need to have the ability to respond quickly to balance the impact of energy fluctuations on the power system and maintain stable power transmission.
  3. Network intelligence: the concept of intelligent transformers is emerging, with integrated sensors and monitoring systems that allow the performance and status of transformers to be monitored in real time. Such intelligent technology can help diagnose faults and carry out predictive maintenance, improving the reliability and efficiency of transformers.

Innovative solutions and future perspectives: To drive the energy transition, transformer technology and solutions need to be continuously innovated. Some potential directions for development include

  1. Efficient materials and design: Research into new materials and design techniques to reduce energy losses and improve efficiency in transformers.
  2. Multi-energy integration: With the increase in renewable energy sources, transformers need to accommodate the integration of multiple energy sources. Research into how to achieve efficient conversion and synergy between multiple energy sources is key.
  3. Energy storage and smart grids: The combination of energy storage technology and smart grids allows for flexible management and optimisation of energy sources. Transformers will play an even more important role in such a system.

 Sustainable energy and transformers are closely linked and optimising transformer design is essential to achieve large-scale integration of sustainable energy. Through improved transformer technology, intelligence and the application of innovative solutions, we can drive the energy transition towards clean, sustainable power systems. Continuous research and development will enable transformers to be better adapted to the needs of sustainable energy in the future and create a greener and more sustainable future for us.
