Abstract

The invention discloses a wind power generation index distribution and additional issue evaluation method considering frequency modulation additional issue, and belongs to the technical field of active control of an electric power system. According to the method, the maximum available output and actual output of each province dispatched wind power virtual unit are calculated through related information in an automatic power generation control information system; a regional dispatching center calculates a whole grid wind power adjustment instruction according to a whole grid wind power consumption space and a modulation frequency instruction condition; the regional dispatching center distributes the wind power adjustment instructions of each province dispatching center according to the maximum available output of each province dispatched wind power virtual unit and by considering the historical output characteristic; and the peak pitching additionally issued electric quantity and frequency modulating additionally issued electric quantity of each province dispatched wind power virtual unit are evaluated according to the adjustment instruction data and the measurement data. By introducing the wind generator set to participate in power grid frequency modulation, wind energy abandonment is reduced while the regulation performance of the system is improved; and by considering fairness and the reward and punishment mechanism in the adjustment instruction distribution, reliability of wind power participated in power grid adjustment is improved.

Description

Technical field [0001] The invention belongs to the technical field of power system active power control, and specifically relates to a wind power generation index allocation and additional issuance evaluation method considering frequency modulation and additional issuance. Background technique [0002] As a renewable energy power generation with mature technology and outstanding economic benefits, wind power has developed rapidly in the past two decades and is gradually becoming one of the main sources of electrical energy supply. With the continuous increase of the installed capacity and grid connection scale of wind power, the randomness and intermittentness of the impact on the safe and stable operation of the power system gradually appear: for the hourly dispatch of the power system, the intermittentness and uncertainty of wind power will be in the unit combination , Tie-line planning, climbing backup, etc.; for minute-level and second-level scheduling, wind power volatility...
