With the promotion of the national "carbon peak and carbon neutralization" policy and related work, the two power grid companies in China put forward the control strategy of taking access to clean energy as the main body on the power side, strengthening the consumption, energy storage, stability and safety of the power grid, and adopting the scheme of electric energy substitution on the user side. Under this development background, China's energy structure will be fastly developed from fossil energy to clean and low-carbon energy. Renewable energy power generation will enter a large-scale "double speed" development stage, and the proportion of non-fossil energy such as wind power, photovoltaic, hydropower and nuclear power will increase significantly. Accelerating the construction of new power system will have a profound and great impact on the development of power industry in the next 40 years. To achieve the "double carbon" goal, the energy field is the main battlefield, the power industry is the vanguard, the equipment manufacturing industry is the core support, and the power transmission and transformation equipment is the core priority. Facing the national "double carbon" goal and the action plan of major power users, Baiyun Power Group is supporting the construction and development of new power system by direct emission reduction, energy conservation and consumption reduction, supporting carbon reduction and green technology, and launch the following solutions: flexible DC transmission system solution, intelligent substation solution, prefabricated cabin substation solution and intelligent distribution grid solution.
