The invention discloses an electrified railway energy router based on a hybrid cascade 81 level. The electrified railway energy router comprises a plurality of distributed power DC to DC converters (DGDC1-DGDCM), a plurality of distributed power AC to DC converters (DGAC1-DGACN), a plurality of distributed energy storage DC to DC converters (ESDC1-ESDCK), a plurality of distributed energy storageAC to DC converters (ESAC1-ESACL), a DC bus capacitor (C), four H-bridge converters (H1, H2, H3, H4) and four single-phase transformers (T1, T2, T3, T4). The distributed power DC to DC converters andAC to DC converters are used for distributed power maximum power point tracking control and boost control, the distributed energy storage DC to DC converters and AC to DC converters are used for DC bus voltage control and power flow control, the DC bus capacitor is used for DC bus voltage support, and the four H-bridge converters and the four single-phase transformers form a hybrid cascade 81 level converter.
