A power distribution method and system for a wind power cluster

Abstract

The invention provides a power distribution method and system for a wind power cluster. The method comprises the following steps that: based on the grid-level dispatching instruction, the optimal windpower output of the wind farm cluster layer is determined by utilizing the preset active power coordinated distribution strategy; Based on the optimal wind power output of wind farm cluster layer, the optimal wind power output of sub-field layer is determined by using the pre-determined active power coordinated distribution strategy. Based on the optimal wind power output of the sub-field layer,the operation of the wind turbine control terminal in the unit layer is controlled. The active power output hierarchical distribution method of the invention combines the hierarchical thought of the large-scale system and considers the coordination and cooperation between different wind farms in the same area at the level of the wind power cluster, further realizes the relative minimization of thesystem network loss and improves the wind power consumption capacity at the same time.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a power distribution method and system for wind power clusters. Background technique [0002] With the rapid development of wind power and wind power base construction, the penetration rate of wind power is increasing year by year, but at the same time, wind curtailment and power curtailment under high penetration rates are also common. One of the main factors restricting the current wind power consumption is the inability to effectively formulate feasible coordination and cooperation strategies among wind farms and within wind farms based on the current dispatching instructions. [0003] In fact, wind power clusters occupy a large area, and due to many reasons such as geographical location and climatic conditions, the output of wind farms and wind turbines at different locations in the wind power cluster will vary greatly. And because the distribution characteristics of w...

One of the main factors restricting the current wind power consumption is the inability to effectively combine the current dispatching instructions to formulate a feasible coordination and cooperation strategy between various wind farms and within the wind farm

[0003] In fact, wind power clusters occupy a large area, and due to many reasons such as geographical location and climatic conditions, the output of wind farms and wind turbines at different locations in the wind power cluster will vary greatly

And because the distribution characteristics of wind resources are often far away from the load center, the difficulty of local consumption has become an important reason restricting the development of wind power
