Abstract

The traditional Voltage Control Area （VCA） division will change with the fluctuation of wind power output. To obtain a stable partition to adapt the various wind power output, this article proposed a method of voltage control area correction considering the impact of wind power. Firstly, in order to study the impact of the fluctuation of wind power output on the partition, the probability distribution of wind power output is discretized into multiple scenarios, and the power flow and partition of each scenario are studied. Secondly, the Jacobian submatrix is used to establish the sensitivity matrix and electrical distance matrix with power factor, and the condensed hierarchical clustering method is used to partition PQ nodes under different cross-section conditions of wind power output. According to the minimum value of Q-V curve, the generators which are consistent with the reactive power limit of PQ node are also classified into a group, and then the remaining PV nodes are divided into the whole network by sensitivity method. Finally, by identifying the boundary of VCA, the broken line analysis method is used to re divide the boundary nodes with inconsistent voltage fluctuations, so as to improve the voltage decoupling degree identifying the boundary of VCA. In this paper, the IEEE 39 bus system is used for wind power processing in multiple scenarios, and the simulation analysis of each output scenario is carried out. The results show that the proposed method can reasonably reflect the partition changes caused by the fluctuation of wind power output, and correct the partition changes under different output scenarios, which provides conditions for the voltage stability control of each region of the system.
