Embodiment Construction

[0043] Affected by resource endowment, coal and other conventional energy sources are the main source of heating. In some areas, low-efficiency small heating methods such as scattered small boilers and small heating stoves are used, which aggravates the emission of air pollutants during the winter heating period. Therefore, making full use of the abandoned wind power in wind power investment warning areas, conducting cross-regional trading of abandoned wind power and using it for clean heating can improve the utilization rate of wind power on the one hand, and achieve energy saving and emission reduction on the other hand. And effective measures to promote green and low-carbon development. The operation of ultra-high AC and DC across regions has effectively improved the power grid's external transmission capacity and provided support for cross-regional abandonment of wind power transactions. Therefore, using abandoned wind power to realize cross-regional trading of abandoned w...

Abstract

The present invention provides a scheduling method and system for curtailment of wind power, including: determining the objective curtailment output of the day-ahead wind power by pre-evaluating the objective wind curtailment output sequence of the day-ahead; and executing the wind power abandonment transaction of the day-ahead according to the objective wind curtailment output of the day-ahead. As a new model to improve the capacity of wind power consumption, this scheme realizes cross-regional trading of abandoned wind power, and maximizes the economic benefits of wind farms and users while ensuring the full utilization of clean energy.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a scheduling method and system for abandoning wind power. Background technique [0002] At present, affected by factors such as power supply structure, resource distribution and power grid structure, the problem of new energy consumption is becoming more and more prominent year by year. Due to the characteristics of randomness, volatility, and intermittency of wind power generation, wind power consumption is directly affected by the regulation capacity of conventional power sources. When the fluctuation range of wind power output exceeds the regulation capacity of the grid, it will lead to wind curtailment. Thermal power units, especially combined heat and power units, account for a relatively high proportion in many areas. Under the demand for heating in winter, combined heat and power units generally operate in the mode of "power fixed by heat", and the peak-shaving cap...
