Analysis of optimal compensation point for reactive power in distribution network based on improved ant colony algorithm

Aiming at the problem of the increase of reactive power due to the influence of harmonics and other factors in the distribution network, a new type of reactive power optimal compensation point search scheme is proposed. The scheme constructs a compensation point analysis system including equipment layer, node layer, communication network layer, computer management layer and remote management center. It can analyze power nodes locally or remotely with a systematic architecture and design a set The harmonic control system can select the power compensation point through online and real-time detection of the harmonic generation point. And the particle swarm optimization algorithm is integrated in the traditional ant colony algorithm, which solves the technical shortcomings that it is difficult to achieve the global optimal solution in the conventional technology. Through 200 iteration calculations, the experiment shows that the method of this study can find the local optimal solution by optimally updating the global position when the predetermined period is reached. The project of this research has certain technological advancement.
