Description

Technical Field

[0001] The present invention belongs to the technical field of electric energy storage, and in particular relates to a method and a device for regulating energy storage constant capacity equipment used for energy storage auxiliary frequency regulation in a power plant. Background Art

[0002] In the operation of the power system, the problem of short-term (seconds or minutes) and random active power imbalance in the regional power grid, that is, the power grid frequency and tie line power control, is mainly achieved through automatic generation control (AGC). It puts forward high requirements on the performance of frequency-modulated power supply, such as fast regulation rate, high regulation accuracy, and frequent switching of power regulation direction.

[0003] The AGC frequency regulation function of the power grid is mainly provided by conventional power sources including hydropower, gas units and thermal power generation units. Since these power systems have response inertia, the conversion of primary energy into electrical energy will go through a series of complex processes. In particular, the AGC frequency regulation performance of the thermal power generation units is still far from the expectations of the power grid, which is manifested in the current situation of regulation delay, deviation (overregulation and underregulation), etc.

[0004] For energy storage systems, within the rated power range, 99%

[0005] The above accuracy can complete the output of the specified power, and its comprehensive response capability is particularly suitable for the power conversion needs within the AGC frequency modulation time scale. According to the research report: On average, the frequency modulation effect of the energy storage system is 1.4 times that of the first hydropower unit, 2.3 times that of the natural gas unit, and more than 20 times that of the coal-fired unit.

[0006] The principle of energy storage-assisted frequency regulation is to use the fast and precise response characteristics of the battery energy storage system to assist the first generator set in load adjustment under the AGC mode, thereby improving the regulation performance of the first generator set, while not causing disturbances to the unit's own regulation. Therefore, configuring a battery energy storage system to assist AGC joint frequency regulation is an inevitable trend for all first generator sets.

[0007] The principle of the power plant side energy storage system access method must not affect the normal operation of the unit and the power grid, the normal operation of the auxiliary equipment for the power plant, and the flexibility of the power plant switching. At present, most of the access solutions for adding energy storage systems to power plants adopt the external power plant bus access solution, that is, the energy storage frequency modulation device is connected to the 6kV power plant working section of the power plant unit with a power cable and connected to the power plant power system.

[0008] In energy storage combined with frequency regulation projects, the general configuration method of energy storage system capacity is mainly based on the grid frequency regulation characteristics. Since 80% of the frequency regulation instructions are about 3% of the full capacity of the unit, 3% of the unit capacity is selected as the energy storage power to ensure that the energy storage system can respond to about 80% of the grid AGC instructions.

[0009] However, the existing energy storage constant capacity equipment has a relatively simple structure, lacks a certain installation and adjustment structure on the outside of the energy storage constant capacity equipment, and the energy storage constant capacity equipment cannot be adjusted accordingly according to actual installation needs, thereby affecting the adjustment efficiency of the energy storage constant capacity equipment.
