[0002] my country's wind resources are concentrated and large-scale, but far away from the load center, it is difficult to absorb them locally
Moreover, in the "Three North" regions where wind power is concentrated, the power supply structure is single, and the proportion of flexible power supply is low. Although the grid-connected capacity has reached a certain level, the wind curtailment is serious. The national "wind curtailment" rate in 2012 was about 17%. It only accounts for 2% of the country's total power generation, whi

Embodiment Construction

[0103] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0104] Due to the fluctuation and instability of wind power output, large-scale wind power grid integration will greatly increase the spinning reserve demand of the system. Regardless of sufficient spinning reserve capacity resources, wind power will seriously threaten the real-time power balance of the grid and the safe and stable operation of the grid in the actual dispatching operation. Therefore, it is necessary to fully anticipate the demand for system reserve capacity that may be caused by wind power fluctuations. It is necessary to plan a certain proportion of fast-adjusting power sources (such as gas turbines and hydropower stations with high regulation performance) to meet the needs of the system in seconds, minutes, hours, and emergency backup.

[0105] Considering the influence of wind power forecast error, load forecast error, and unit sudden tri...

Abstract

The invention provides a wind power consumption ability analysis method considering the standby requirement. The method includes the following steps that a standby requirement probability distribution model is established after wind power integration is conducted; standby constraint conditions are determined; a production simulation model considering the standby requirement is established; according to the generated simulation model, the wind power consumption ability is analyzed. According to the method, the standby requirement probability distribution model is established after wind power integration is conducted, the optimal required reserve capacity is obtained after wind power integration is conducted so that a start-up mode and a service capacity plan curve of a unit can be optimized, the wind power consumption ability can be improved, and a reference is provided for regional power grid planning.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation planning, and in particular relates to an analysis method of wind power consumption capacity considering backup demand. Background technique [0002] my country's wind resources are concentrated and large in scale, but they are far away from the load center, making it difficult to absorb them locally. Moreover, in the "Three North" regions where wind power is concentrated, the power supply structure is single, and the proportion of flexible power supply is low. Although the grid-connected capacity has reached a certain level, the wind curtailment is serious. The national "wind curtailment" rate in 2012 was about 17%. It only accounts for 2% of the country's total power generation, which is still very small. [0003] With the rapid development of wind power, the system’s demand for backup is increasing, that is, other types of units in the power system are required to provide m...
