Introduction  Under the vision of carbon peak and carbon neutralization, the construction of the new power system substations is imperative.

  Method  To promote the transformation of traditional substations to new power system substations, a full-lifecycle green and low-carbon construction scheme for new power system substations was proposed. Focusing on electrical equipment, building structures, building equipment and integrated energy, the carbon emissions throughout the entire life cycle of substations were reduced, and the new power system substations were constructed and operated in a green and low-carbon manner.

  Result  The results show that compared with conventional substations, the proposed green and low-carbon construction scheme not only improves the development and utilization of renewable energy and accelerates the low-carbon upgrade of power grids, but also promotes energy saving and consumption reduction of power grid equipment, reduces carbon emissions and O&M costs of substations, and improves the utilization level of basic resources of substations, thus improving the comprehensive economic benefits of the substations.

  Conclusion  The proposed green and low-carbon construction scheme has certain universality and replicability. It can provide theoretical and practical guidance for the transformation and transition of substations, and lay the foundation for the low-carbon development of the power grid.
