Analysis on the potential supply and demand of flexible resources in a certain regional system in China under the dual-carbon target

First, under the dual-carbon concept, the importance of flexible resource construction and planning in the power system is pointed out. Then combined with the actual situation of China’s market construction and electric system, the concept of power system flexibility is enriched from the perspective of supply and demand. The current types of flexibility resources, their advantages and disadvantages, the direction of upward and downward adjustment, the response time scale are Summarized, as well as the practice of international flexibility resources trading. flexible resource planning should be greater than flexible demand. At the same time, the calculation methods of various flexibility requirements in the power system are given from the perspective of mathematical statistics, and the actual data of a certain region of China are calculated and analyzed from different periods of time. Finally, some suggestions for flexible resource planning are given.
