With the promotion of new power system construction and new energy comprehensive participation in market trading, the source-load bilateral stochasticity causes increasing system balance problems. By comparing the existing system balance risk response mechanism at home and abroad, it is found that the market construction of flexibility resources in China is relatively backward. Therefore, the intraday multiple flexible resource matching transaction based on the deviation linkage of generator-user alliance is proposed. Firstly, the main body of balance responsibility of the “generator-user alliance” deviation linkage is proposed, and the market framework of the intraday multiple flexible resource matching transaction based on the deviation linkage of generator-user alliance is constructed. Then, the intraday generator-user alliance deviation linkage resources matching transaction model is established. Finally, the IEEE 18-node system example is used to prove that the proposed transaction can effectively incentivize the system regulation potential, reduce the system balancing cost, mitigate the deviation price risk of the operating entities to a certain extent, and at the same time, enhance the flexible resource cost recovery ability.
