S&T Supporting Realization of Carbon Peak and Carbon Neutrality Goals - Breakthroughs in Key and Core Technologies

Abstract

Under the 'carbon peak and carbon neutrality' goal, the supply and demand of China's power system will continue to grow in the next 40 years. Firstly, this study comprehensively analyzes China's power grid system under the goal of carbon neutralization. In the future, wind power and solar power will gradually become the main power supply, which brings new tasks and challenges to the power grid to absorb the renewable energy. On this basis, the general idea and construction principles of building a new generation of power system are expounded. Then, the basic structure and form of the new generation of power system are analyzed. Due to the continuous expansion of longdistance transmission scale and the imbalance of resources and load in the future, the new generation of power system still has the remarkable characteristics of reverse distribution between the power supply and the load. Therefore, its basic form is still composed of large power and effectively supplemented by distributed power system. In addition, the flexible regulation of resources in the power grid is very important for the safe operation of the power grid, the power market operation mechanism should guide multiple subjects to participate in the construction of the new generation of power system. Finally, the phased implementation strategy of building a new power system for carbon neutralization is proposed, which has an important guiding role on building the new power system and realizing carbon neutralization.
