Abstract

The invention provides primary frequency modulation control method and system of a new energy power station. The primary frequency modulation control method includes: calculating active power output regulating variables and new active power reference values on primary frequency modulation of the new energy power station; evaluating active power output margins of power generation units in the new energy power station; calculating the active power output regulating variables of the power generation units according to the active power output margins; according to the new active power reference values and the active power output regulating variables of the power generation units, calculating the active power reference values of the power generation units, and the power generation units performing active power output according to the active power output values. Compared with the prior art, the primary frequency modulation control method and system has the advantages that both the active power output regulating variables of the new energy power station and the active power output margins of the power generation units are taken into consideration, and grid-connection frequency of the new energy power station can be regulated under the premise of safe operation of the power generation units.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a primary frequency modulation control method and system for a new energy power station. Background technique [0002] As an important index to measure power quality, grid frequency is related to the normal operation of electrical equipment and the quality of power consumption of users. When the power system is running, real-time and random changes in the load of the power system will cause real-time and random fluctuations in the grid frequency. Therefore, stabilizing the grid frequency of the power system to operate near the rated value is one of the main goals for the safe and stable operation of the power system. one. Among them, the primary frequency regulation control of the power system can be used to eliminate the frequency fluctuation phenomenon of the power grid caused by the first type of load change in the power system. [0003] With the continuo...
