<p>An optimization control method for a reactive voltage of a wind farm cluster comprises the following steps: determining whether it is required to perform optimization control on a reactive voltage of a wind farm cluster; obtaining adjusting ranges of reactive source devices of wind farms and pooling stations in a cluster area; and establishing and solving a reactive voltage optimization control mathematic model of the wind farm cluster. In the optimization control method for a reactive voltage of a wind farm cluster, a wind farm cluster access point is used as a central voltage control node, and the wind farm integration point bus voltage, the wind farm step-up substation tap, the reactive power output of a reactive compensation device of the pooling station, and the pooling station transformer tap in the cluster area are adjusted; in this way, the central node is ensured to satisfy the control instruction range of a scheduling mechanism, and the stability margin of the static voltage in the cluster area maintains at the maximum and the active power loss maintains at the minimum, thereby improving the security stability during system operation and enhancing the capability of utilization of the wind power.</p> |
