| description | To promote intelligent application of bidirectional converters in active power supply, the mathematical model and scheduling control strategy were studied in this paper. The full power and constant voltage models were used to simulate the two different working conditions of the bidirectional converter, and the internal and external double-layer iterative algorithm was used to calculate the power flow. When all the bidirectional converters were in constant voltage mode, the minimum energy consumption of the whole network was taken to solve the output voltage equation of the traction substation and optimization model of inequation constraints. When the full power mode of a bidirectional converter existed, the strategy of raising or lowering the voltage of neighboring stations to share the power was proposed to reduce the full power duration of the bidirectional converter. The simulation results of actual metro line data show that the pure traction energy consumption decreases by 12.97% and the full power duration decreases by 62.4%, which improves the energy utilization rate of the traction system and reduces the power-limiting scene of the bidirectional converter. |
