Wind power cluster scheduling system based on multi-objective collaborative optimization method

Abstract

A wind power cluster dispatching system based on a multi-target collaborative optimization method comprises a power grid dispatching center, a cluster intelligent unit and wind power plant clusters, the cluster intelligent unit is in signal connection with the multiple wind power plant clusters, and each wind power plant cluster comprises multiple wind power plants. The signal output end of the power grid dispatching center is in signal connection with the signal input end of the cluster intelligent unit and is used for issuing dispatching indexes to the cluster intelligent unit; and the cluster smart unit is in signal connection with the plurality of wind power plant clusters and is used for sequentially distributing power generation indexes of the power grid dispatching center to each wind power plant cluster and each wind power plant according to priorities. According to the method, the defects in the prior art are overcome, the overall power generation efficiency of the wind power plant cluster in the region is optimized, the resource waste of a wind power enterprise is reduced, and the stability and safety of wind power integration are effectively improved.

Description

technical field [0001] The invention relates to the technical field of wind power scheduling and control, in particular to a wind power cluster scheduling system based on a multi-objective collaborative optimization method. Background technique [0002] Wind power has the characteristics of mature technology and large-scale utilization, and with the continuous expansion of installed capacity, it has gradually become one of the new energy power generation methods with the most large-scale development conditions and commercial development prospects. my country's wind power installed capacity is large and far away from the load center. The wind power cluster composed of a large number of wind farms must be transported to the load center for consumption through transmission channels of different voltage levels. Limited by the transmission capacity of the transmission channel, the problem of wind power consumption is very prominent. The phenomenon of wind power rationing has not b...

Problems solved by technology

The conventional dispatching mode is that the grid company directly dispatches wind farms, which requires the grid to have sufficient reserve capacity to balance wind power fluctuations, which not only increases the cost of grid dispatching and operation, but also results in lower overall power generation efficiency among wind farms , a great waste of wind resources
