In a world undergoing transformation, the transition to renewable energies is not only desirable but imperative to combat climate change and ensure a sustainable future. The electrical grid, as the backbone of our energy infrastructure, is now technically prepared to accommodate a growing share of renewable energy, whether it be through wind, solar, or other innovative green sources. However, this technical advancement cannot be realized without your commitment and support. Whether it is through adopting more sustainable practices, innovation at the individual or collective level, your contribution is essential to transform this opportunity into reality. By joining our efforts, we can all play a key role in this energy revolution and build a future where renewable energies reign supreme.
Sophie, 29 years old, passionate about bioenergies and waste management, enlightens you on the importance of public support for the expansion of renewable energies in our electrical grid.
The transition to a greener electrical grid
To enable the electrification of our vehicles, heating systems, and household appliances, the electrical grid must not only expand by 57% but also become more flexible. Sources of solar and wind energy are set to dominate the energy landscape of tomorrow. However, they are often located in remote areas away from consumption centers, posing challenges for the current transmission system.
The challenges of integrating renewable energies
The current transmission system is not designed to handle the influx of energy from these remote areas. For example, a particularly sunny day in the desert can lead to blackouts or overload the power lines. To address these issues, it is crucial to better control the distribution of energy within the distribution system.
A revolutionary technology for better energy management
A team of experts from the National Renewable Energy Laboratory (NREL), in partnership with universities, has developed a testbed for a new grid technology. This device, called a back-to-back medium-voltage converter, would allow operators to better regulate the flow of electricity with a fraction of the weight and costs of current technologies.
The benefits of medium-voltage converters
Unlike traditional transformers, these converters can automatically redirect energy, thus reducing service interruption times. They are also much more compact, reducing costs and delivery times. These converters enable solar panels to transmit their energy more efficiently by eliminating unnecessary conversions.
The development and securing of the new technology
Although promising, this technology still requires rigorous testing to ensure its effectiveness, profitability, and safety. The NREL team has built a replica of the power system to evaluate these converters, ensuring maximum safety for technicians and costly prototypes.
Your involvement is essential
For this technology to reach its full potential and be integrated into the electrical network, increased public and policy support is essential. By encouraging research and funding, everyone can contribute to the transformation of our electrical grid into a more resilient and reliable system.
Future perspectives
With the increasing interest in medium-voltage conversion, more and more applications will emerge. The NREL plans to use its testbed to further explore medium-voltage grid technologies and energy alternatives such as hydrogen. Thus, this technology promises to be an essential pillar for a clean energy future.
