Voltage and reactive power control strategy of transmission networks based on fuzzy theory
In order to solve the voltage stability control problems for high-complexity power systems under the background of new energy,electric vehicles,energy storage and other new technologies,a voltage and reactive power control strategy for transmission networks based on fuzzy theory was proposed.This method introduced the membership function in fuzzy theory,and formulated reactive power control strategies according to the coupling degree between system nodes and different partitions.In addition,the electrical distance among each node of the network was calculated according to the sensitivity analysis;the fuzzy clustering algorithm was used to perform the preliminary partition for the nodes;the clustering fusion algorithm was used to perform fusion calculation of the multiple results generated by the clustering for the final partition results.The primary and secondary control strategies based on the membership of key nodes to each partition were thus formulated.Test example of IEEE 30 bus system was simulated accordingly.The results show that this strategy can control reactive power effectively.
