Primary Frequency Modulation Control Strategy For Flywheel Energy

Compressed air energy storage primary frequency modulation

Combined with its own characteristics, the parameters such as dead band, speed governor droop and limit bound are analyzed and set up, which lays the foundation for compressed air energy storage to participate in primary frequency regulation of power grid. . Compressed air energy storage (CAES)is a high-quality power source for grid regulation with strong peak-regulating capability and weak frequency-regulating capability, in order to alleviate the frequency problem caused by the large scale integration of renewable energy power generation. In this. . The primary frequency modulation performance of the compressed air energy storage system on the power generation side and the power consumption side was comprehensively tested by constructing a test system with a switch and developing static and dynamic test methods. By constructing a test system. . The invention discloses a method for participating in primary frequency modulation of a power grid by compressed air energy storage, which comprises the following steps: a primary frequency modulation function module is arranged in a thermal control system of an expansion generator of a compressed. . According to the national standard, and referencing the same type of generation unit, the primary frequency modulation function of compressed air energy storage is constructed. [PDF Version]
