Voltage Partition Coordinated Control of Distribution Network With Distributed Photovoltaic Based on CFSFDP Algorithm

With a large number of distributed photovoltaic power integrated into distribution network, the emergency of important load nodes the voltage exceeds the limit is more likely to occur, which puts forward higher requirements for the rapidity of voltage control by the current power flow calculation. Considering the complicated control process of the centralized voltage control and the traditional time-consuming partition method, the electrical distance of load nodes is calculated firstly according to the comprehensive voltage sensitivity, and the node similarity matrix is constructed based on the electrical distance. The distribution network is partitioned rapidly by using the algorithm of Clustering by fast search and find of density peaks(CFSFDP). Then in view of insufficient voltage regulation capacity of local independent photovoltaic source, the coordinated voltage partition control strategy is proposed considering reactive power and active power successively. Finally, the simulation results of the IEEE 33 nodes distribution network verify the rapidity of the proposed method and effectiveness of the voltage partition coordinated control strategy.
