Multi Objective Cluster Partitioning and Voltage Coordination Control in Distribution Networks Based on Improved Louvain Algorithm and BAAM-ADMM
Targeting the problem of voltage violation in distribution network integrating with distributed photovoltaic(DPV)power station,the paper proposes a cluster partitioning and voltage coordination control method for DPV power station connected to the distribution network.Firstly,the distribution network containing DPV is divided into clusters by using an improved Louvain algorithm.Then a voltage optimization control model is established with the objective of minimizing photovoltaic active power reduction,the network loss,and node voltage deviation.The model is solved to realize the voltage coordinated optimal control using an alternating direction multiplier method(ADMM)in the bidirectional Anderson acceleration algorithm(BAAM)according to the mutual information between inter-clusters and cluster itself.Finally,the proposed control method is validated with an improved IEEE 33-node system.The results show that the proposed method can achieve the voltage coordinated optimal control in DPV power station,improving the network friendliness of DPV power station.
