Wind farm active power control method considering alternative trading of wind power and thermal powder

Abstract

The invention relates to a wind farm active power control method considering alternative trading of wind power and thermal powder, which is technically characterized by comprising the steps of 1, establishing a wind and thermal power alternation scheme model Mi; 2, setting a control mode of the model Mi, control parameters of an allocation algorithm, and output limit values of thermal power plantor a thermal power unit; 3, calculating power generation capacity delta pi vacated from the thermal power plant in the wind and thermal power alternation scheme model Mi; 4, allocating the power generation capacity delta pi, vacated from the thermal power plant in the wind and thermal power alternation scheme model Mi, to wind farms in the model Mi; 5, calculating active power control commands according to calculating results of a virtual load rate; 6, issuing the wind farm active power adjustment commands, acquired by calculating, to the wind farms for execution. The method herein has the advantages that the demand for alternative trading of wind power and thermal power can be responded to in real time, a most suitable control strategy is applied to wind farm reactive power, execution ofa wind and thermal power alternative trading plan is guaranteed for each wind farm, and fair scheduling among the wind farms is considered.

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 the huge reserves of wind energy that can be developed and utilized provide a good resource base for the rapid development of the wind power industry. In recent years, China's wind power installed capacity has continued to increase, and the scale of wind power grid connection has gradually expanded. Due to the unbalanced distribution of wind energy resources, China's wind power is mainly concentrated in the "Three Norths" (...

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
