Abstract:With the proposal of "dual carbon" goal, China will accelerate the construction of new power system that adapts to the increasing proportion of new energy, and vigorously developing low-carbon energy is an inevitable path to achieve the "dual carbon" goal. Firstly, the coupling relationship between "dual carbon" goal and new power system is studied, and the development of new power system is analyzed. Secondly, considering the environment and its own characteristics of new power system in China, ]from the macro and micro levels, the PEST-SWOT analysis method is adopted to comprehensively analyze its own advantages +2]and disadvantages in politics, economy, society and technologies in the construction of new power system, as well as the ]opportunities and threats faced. Finally, based on the above analysis, targeted policy suggestions and effective measures are put forward under different development strategies to provide a reference for the construction of new power systems.
