Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power energy storage, and particularly relates to a regulating method and device of an energy storage fixed-volume equipment for power plant energy storage auxiliary frequency modulation. BACKGROUND

[0002] In the operation of a power system, the problem of short-time (second or minute level) random active power imbalance in a regional power grid is solved, that is, power grid frequency and tie-line power control is mainly realized through automatic generation control (AGC). The performance of the frequency modulation power source is required to have fast regulation rate, high regulation accuracy and frequent power regulation direction conversion.

[0003] The AGC frequency modulation function of the power grid is mainly provided by conventional power sources including hydropower, gas turbine units and thermal power units. Since these power source systems all have response inertia, a series of complex processes will be experienced in the conversion of primary energy into electric energy, and in particular, the AGC frequency modulation performance of the thermal power unit still has a large gap compared with the expectation of the power grid, which is manifested as regulation delay, deviation (over-regulation and under-regulation) and the like.

[0004] For an energy storage system, within the rated power range, it can output a specified power with 99% accuracy within 1 second.

[0005] The above accuracy completes the output of the specified power, and the comprehensive response capability is particularly suitable for the power conversion demand within the AGC frequency modulation time scale. According to a research report, on average, the frequency modulation effect of the energy storage system is 1.4 times that of the 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 auxiliary frequency modulation is to utilize the characteristics of fast and accurate response of the battery energy storage system to assist the thermal power unit in load adjustment in the AGC mode, thereby improving the regulation performance of the thermal power unit, and at the same time, not bringing disturbance to the unit itself. Therefore, the configuration of the battery energy storage system to assist AGC combined frequency modulation is an inevitable trend for all thermal power units.

[0007] The access mode of the energy storage system on the power plant side must meet the principles that it cannot affect the normal operation of the unit and the power grid, cannot affect the normal operation of the auxiliary equipment, and cannot affect the flexibility of the plant auxiliary power switching. At present, the access scheme of the energy storage system added to the power plant mostly adopts an external plant auxiliary power bus access scheme, that is, the energy storage frequency modulation device is connected to the 6kV plant auxiliary working section of the power plant unit through a power cable, and is connected to the plant auxiliary power system of the power plant.

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

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