A Wind Farm Active Power Control Method Considering Alternative Trading of Wind and Fire

Abstract

The present invention relates to a kind of wind farm active power control method that considers wind-fire alternative transaction, and its technical feature is: comprise the following steps: Step 1, establish wind-fire alternative scheme model M i ;Step 2, set M i The control mode of the control mode and the control parameters of the distribution algorithm and the output limit of the thermal power plant or the output of the thermal power unit; step 3, calculating the wind-fire alternative model M i Power generation space Δp vacated by China Thermal Power Plant i ; Step 4, the wind-fire alternative model M i Power generation space Δp vacated by China Thermal Power Plant i assigned to M i The wind farm in the wind farm; step 5, calculate the active power control command according to the calculation result of the virtual load rate; step 6, send the calculated active power adjustment command of each wind farm to each wind farm for execution. The invention can respond to the demand of wind-fire substitution transaction in real time, implement the most suitable control strategy for the active power of the wind farm, ensure the execution of the wind-fire substitution transaction plan of the wind farm, and take into account the fair scheduling among wind farms.

Description

technical field [0001] The invention belongs to the technical field of operation and control of a new energy access power system, and relates to a wind farm active power control method, in particular to a wind farm active power control method considering wind-fire substitution transactions. Background technique [0002] Wind energy is a kind of abundant and renewable clean energy. Reasonable and effective use of wind energy is one of the effective ways to adjust the energy structure and solve the energy crisis. China is rich in wind energy resources and has huge reserves of wind energy that can be developed and utilized, which provides a good resource foundation for the rapid development of the wind power industry. In recent years, the installed capacity of wind power in China has continued to increase, and the scale of wind power grid-connected has gradually expanded. Due to the uneven distribution of wind energy resources, China's wind power is mainly concentrated in the ...

AI Technical Summary

Problems solved by technology

[0018] The traditional new energy active power control system does not consider the factors of the wind-fire substitution transaction, and the adjustment target of the wind-fire substitution transaction cannot be reflected in the automatic control

Scheduling operators can only rely on manual adjustments, and cannot guarantee the accurate execution of the Fenghuo alternative trading plan
