Embodiment Construction
[0037] The technical solution of the present invention will be further introduced below in combination with specific embodiments.
[0038] The structure of the IPFC adopted in this specific embodiment is as figure 1 shown. This specific embodiment discloses a method for improving the convergence of the IPFC power injection model in power flow calculation, such as image 3 shown, including the following steps:
[0039] S1: Initialize the power flow equation, set the number of iterations k to 1; set the IPFC control target value, and set the active power flow P of the main control line 1 control at P 1ref , the reactive power flow Q of the main control line 1 control in Q 1ref , the active power flow P of the auxiliary control line 2 control at P 2ref ; among them, P 1ref The control target of the active power flow of the main control line, Q 1ref The control target of the reactive power flow of the main control line, P 2ref is the control target of the active power fl...
