Problems solved by technology

Its shortcoming is that it only analyzes the power balance at peak and trough times to obtain wind power consumption power, but cannot calculate the wind power consumption power within a period of time, and does not propose wind power consumption capacity from the perspective of reasonable wind curtailment

Abstract

The invention provides a wind power consumptive capacity calculation method and system. The method comprises the steps of acquiring power grid electrical load data, power grid conventional unit data, power grid and external power grid electric power exchange data, and power grid wind power output characteristic data of a power system in a preset time; calculating the boot capacity and reserve capacity of the power system through the acquired data; determining a boot mode of a unit by combining the maintenance of the unit based on the calculated boot capacity; calculating a peak modulation margin of the power system based on the boot mode; and calculating the power grid wind power consumptive capacity according to the peak modulation margin of the power system, without considering situations of wind curtailment and electricity limitation, and outputting the power grid wind power consumptive capacity without wind curtailment. The wind power consumptive capacity calculation method and system can calculate the consumptive capacity for different research needs, thereby providing support for research on wind power planning and consumptive wind power scheduling modes.

Description

technical field [0001] The invention relates to a calculation method for wind power accommodation capacity, in particular to a calculation method and system for wind power accommodation capacity. Background technique [0002] In the existing technology, the wind power accommodation capacity of the power grid in the research area is mainly concentrated on the maximum allowable wind power installed capacity under the condition that the system does not limit the wind power output, which is used to characterize the system's ability to accommodate wind power, and the calculation is a single-point balance calculation. This method collects the load power, unit data, and external power of the power grid system within a certain period of time, and comprehensively considers the power balance of the power grid system under the peak and valley load levels, the start-stop status and output range of each unit, and combines the above factors Unified optimization to obtain wind power absorp...
