Wind-power-plant-having-access-to-power-grid position and capacity control method with minimum wind curtailment considered

Abstract

The invention relates to a wind-power-plant-having-access-to-power-grid position and capacity control method with the minimum wind curtailment considered, and belongs to the technical field of power grid planning. According to the method, firstly a wind power plant wind curtailment capacity computing method is proposed with the power grid peak-shaving margin and the power grid transmission line transmission power constraint considered. On the basis of the wind power plant wind curtailment capacity computing method, a computing method for the wind power plant wind curtailment probability and wind power plant expected wind curtailment capacity is proposed based on a monte carlo simulation method. Finally the wind-power-plant-having-access-to-power-grid position and capacity control method with the minimum wind curtailment considered is proposed. By means of the method, the admitting ability of the power grid to the wind power can be fully considered, the wind power plant wind curtailment mechanism is analyzed from two aspects of the power grid peak-shaving margin and the power grid transmission line transmission capacity constraint, the wind-power-plant-having-access-to-power-grid position and capacity is controlled with the wind power plant minimum wind curtailment as the target, and finally the wind power plant access scheme is obtained so that the power grid can admit the wind power at a greater degree, and the new energy utilization efficiency is effectively improved.

Description

technical field [0001] The invention relates to a control method for the position and capacity of a wind farm connected to a power grid considering the minimum abandoned wind, and belongs to the technical field of power grid planning. Background technique [0002] With the increasingly severe energy and environmental problems, countries all over the world are competing to vigorously develop renewable energy. With its advantages of environmental protection, abundant resources, easy development, and gradually increasing cost performance, wind power has been widely valued by countries all over the world, especially developed countries. As a typical clean and renewable green energy, wind energy is non-polluting, sustainable and intermittent. Using wind power to replace part of the conventional energy generation to participate in the dispatching arrangement of the power system can greatly reduce the consumption of fossil energy such as coal and reduce the cost of power productio...
