The invention discloses an MMC power operation interval optimization method based on an energy flow rule, and the method can achieve the maximum power transmission of a flexible DC power transmission(MMC-HVDC) system under an AC side fault. Firstly, fault feature analysis is carried out on an alternating current side; an energy distribution condition and an instantaneous energy fluctuation characteristic under different fault types of the alternating current side are understood, a coupling relationship between an energy dynamic process and each electrical parameter of the system is constructed, and the energy conversion rule of the flexible DC power transmission system is found, so that an MMC operation power interval is optimized based on the energy conversion rule, the analytical expression of the maximum active power transmission capability of the MMC under different fault working conditions is constructed, and the optimal energy distribution of the MMC-HVDC system is determined.
