Title:
FLUCTUATION PRESSURE POWER GENERATION CONTROL METHOD AND DEVICE FOR POWER GENERATION-ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/071809
Kind Code:
A1
Abstract:
Disclosed is a fluctuation pressure power generation control method and device for a power generation-energy storage system. The fluctuation pressure power generation control method for a power generation-energy storage system of the present invention comprises: calculating a difference between an actually measured power value Nmeas and a target power value Nref, and obtaining an active power error signal; calculating a difference between an actual air pressure Pmea and a set air pressure value Pref, and obtaining an air pressure error signal, and summing the active power error signal and the air pressure error signal to obtain a multivariable control signal; and controlling, according to the multivariable control signal, the working state of an air pressure regulating valve between a high-pressure gas system and a gas-liquid mixing system of the power generation-energy storage system in a power generation stage. According to the present invention, stable control of power in a power generation process can be achieved, a control method is provided for the power generation-energy storage system to achieve constant output of power of a generator set under pressure fluctuation, and an important theoretical support and practical basis are provided for improving the flexibility of a power system.
