The invention discloses an electric power motor train unit grouping method more flexible and belongs to the field of motor train unit grouping methods of electric power motor train unit vehicles based on electric power electronic transformers. According to the electric power motor train unit grouping method, carriages, except a train head and a train tail, of a motor train unit are provided with novel electric power electronic transformers which have the functions of transformers and also the functions of traction convertors and serve as novel power supply devices so that a traction drive system of the whole train can be more efficient, capable of better saving energy and lighter, the pantograph layout and the grouping method of basic motor train units are improved based on the fact, and the electric power motor train unit grouping method is more flexible. In addition, the industrial Ethernet serves as a new communication bus between all novel motor train carriages and a drive control system to replace a traditional rail vehicle MVB communication bus, the data transmission efficiency is improved, the congestion probability is reduced, the overall system reliability of coupling or decoupling of the motor train is improved, and safety of the train during running is improved.
