HPFC control parameter calculation method based on additional node and equivalent voltage source

The invention discloses a hybrid power flow controller (HPFC) control parameter calculation method based on an additional node and an equivalent voltage source. An HPFC equivalent model with series transformer coupling reactance and additional nodes is established, an injection power expression with reactance is deduced by combining a superposition principle, and a power injection model of the HPFC is obtained; then, an equivalent voltage source is divided in the HPFC, the voltage of the equivalent voltage source is calculated according to a power flow control target, and control parameters of the HPFC are calculated according to related voltage configuration rules; according to the calculation method provided by the invention, a Jacobian matrix does not need to be modified in an iteration process, parameters such as line impedance, susceptance and coupling transformer impedance can be effectively processed, and the iteration speed of load flow calculation can be accelerated; by dividing an equivalent voltage
