Description
technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a dynamic test system and a test analysis method for a primary frequency regulation of an energy storage power generation side. Background technique [0002] The primary frequency regulation of the power system refers to the use of the inherent load frequency characteristics of the system and the role of the governor of the generator set to prevent the system frequency from deviating from the standard adjustment method, which can make the generator set respond to the changes in power and frequency on the grid side in real time, and improve the overall performance. The frequency control level and power quality of the power generation and power supply system ensure the safety and stability of the entire power generation and power supply system. [0003] The compressed air energy storage system can realize the energy release of power generation and the energy stor...
