AB - In order to solve the problem of energy consumption, improve the efficiency  of energy utilization and develop new energy, the total energy consumption  and fluctuation of thermal integrated energy were analyzed. Four  suggestions are put forward for the integrated power system of flexible  thermal power plant, namely, electric heat storage system, electric heat  pump heat storage system, g, heating system and high pressure heating system  via steam turbine, which can improve the air energy consumption capacity of  the system and reduce the total coal consumption of the system. Among them,  in the case of small air conditioning units or small air conditioning units  do not use electric heating furnace and electric heat pump furnace. Heat  storage technology of thermal power unit is not suitable for daily exhaust.  In contrast, the high pressure/IP bypass heating process of steam turbine is  more flexible and less restrictive, which is the best method for comparison.  Compared with other schemes discussed by the author, this scheme has the  highest flexibility and the least restrictions, and is the best one among  the four.
