Collaborative Voltage Automatic Control System of Distribution Network Based on Particle Swarm Algorithm
Aiming at the problems of feeder power imbalance and voltage over-limit caused by increasing types of distributed power access and increasing penetration rate in distribution network,a coordinated voltage automatic control system of distribution network based on improved particle swarm algorithm is proposed.Firstly,consider the timing,instability and load influence of distributed power supply,and establish the corresponding mathematical model.Then,the corresponding two-layer co-voltage model is constructed,and the particle swarm algorithm is improved based on adaptive ε-domi-nance.After the study and verification,the improvement of the coordinated voltage automatic control system can better ensure the power balance of the distribution network and avoid voltage over bound.
