The invention discloses a power transmission network congestion control method based on a VSC (Voltage Resourced Converter) and high voltage distribution network topology reconfiguration. The high voltage distribution network topology reconfiguration is used to build a power flow adjustment path for the VSC; the power flow distribution is adjusted by utilizing the VSC power regulation capability;the control cost and the load loss are the minimum is taken as an optimization goal; and a fireworks optimization algorithm is adopted to solve a power transmission network congestion control model, which ensures the safe and stable operation of an urban power transmission network under continuous time.
