A Distributed Reactive Power Optimization Method for Active Distribution Network Based on Equal Network Loss Slight Increment Rate

Abstract

The invention discloses an active power distribution network distributed type reactive optimizing method based on an equal network loss increment rate. The control method comprises steps that step 10) initialization: partition reactive optimization parameters are initialized; step 20) partition reactive optimization solution: according to a partition trend calculation result, the equal increment rate is used to solve reactive power adjustment amounts of various distributed power supplies and reactive compensation devices; step 30) inter-partition information interaction: information interaction between adjacent partitions is carried out, and the operation states of the partitions are updated; step 40) convergence determining: whether active power deviation of a main station node is smaller than a predetermined convergence threshold is determined, and when the active power deviation of the main station node is smaller than the predetermined convergence threshold, iteration is stopped, and when the active power deviation of the main station node is not smaller than the predetermined convergence threshold, whether a maximum iteration time is achieved is determined, when the maximum iteration time is achieved, the iteration is stopped, and when the maximum iteration time is not achieved, the iteration time is plus one, and the step 20) is carried out again. The control method is advantageous in that based on a distributed type communication architecture and an equal network loss increment rate rule, convergence speed is fast, and the reactive distributed type coordinated optimization of a plurality of partitions and distributed type optimization of global network losses are realized, and robustness of active power distribution network reactive optimization control and reliability of power supply are improved.
