Embodiment 1
[0127] The embodiment of the present invention provides a distributed wind farm optimization operation method based on variable power factor, establishes a static voltage load model of the distribution network considering different load types, and adopts an improved firefly algorithm to solve the dynamic adjustment of the optimal power factor. The objective function is to reduce voltage deviation and reduce active and reactive network losses.

Embodiment 2
[0224] This embodiment provides an algorithm verification for a variable power factor-based distributed wind farm optimal operation method, as follows:
[0225] The IEEE-33 node distribution network architecture is used for verification. Among them, the IEEE-33 node system with 3 access points has 32 branches, 5 tie switch branches, and 1 power network, and the reference voltage at the head end is 12.66 kV. The active power and reactive power of the connected load are 3.72MW and 2.30Mvar respectively. Considering 4 single load types (RL, IL, CL, CPL) and mixed load types, in ML, let IL, RL, CL account for 40%, 45% and 15% respectively.
[0226] In the simulation, it is assumed that mixed loads are used to replace the access of traditional constant loads at each node, and the access capacity is consistent with that of traditional loads. The topology of decentralized wind farm access based on DFIG is as follows: Image 6 As shown, the IEEE-33 node system is accessed through t...
