Abstract

The invention provides a wind-solar complementary rapid frequency modulation control method, which comprises the following steps of: setting a system rapid frequency modulation dead zone, and starting energy storage equipment when the system frequency enters the rapid frequency modulation dead zone; collecting CT signals and PT signals of a power station, and obtaining power station operation parameters including frequency, voltage and active power; and receiving the active power adjustment instruction forwarded by the AGC in real time, and performing frequency modulation according to a preset frequency modulation strategy in combination with the real-time frequency of the power system. According to the invention, high-frequency and high-precision measurement can be carried out on the operation parameters of the power station system by adding the high-speed frequency measurement device, the real-time frequency value of the power system and the future output trend corresponding to the current state are obtained through analysis in combination with the active power adjustment instruction forwarded by AGC, and the system frequency is adjusted. The wind and light system has the frequency response characteristic, effectively and quickly participates in system frequency modulation, reduces or avoids negative effects on system frequency modulation, and avoids sacrificing the wind energy utilization rate and the solar energy utilization rate.

Description

technical field [0001] The invention relates to the field of power system frequency modulation, in particular to a wind-solar complementary fast frequency modulation control method and system. Background technique [0002] At present, wind energy and solar energy have been effectively applied to the power system as new energy sources, and wind energy and solar energy are complementary in time and area. , Continuous power output. [0003] However, in practical applications, due to the unstable output and the large impact of the environment, wind and solar hybrids need to be improved in supporting the stability of the power system. Contents of the invention [0004] The purpose of the present invention is to provide a wind-solar complementary fast frequency modulation control method and system. By adding a high-speed frequency measurement device, high-frequency and high-precision measurement of the operating parameters of the power station system is performed, combined with...
