[0002] In their daily operations, grid-connected thermal power plants need to provide grid-connected operation functions, performance and ancillary services, including frequency regulation services such as primary frequency regulation and automatic generation control (AGC).

[0003] Primary frequency regulation is an automatic control process in which the control system of the unit in the power grid automatically controls the increase or decrease of the unit's active power when the frequency of the power grid deviates from the rated value, limits the change of the power grid frequency, and maintains a stable power grid frequency. When the power grid frequency increases, the primary frequency regulation function requires the unit to use its heat storage and other means to quickly reduce the load, and vice versa, the unit quickly increases the load. The assessment indicators of primary frequency regulation generally include correct action rate and performance indicators.

[0004] Automatic generation control (AGC) refers to the service that the generator set follows the power dispatching instructions within the specified output adjustment range and adjusts the power output in real time at a certain adjustment rate to meet the power system frequency and tie line power control requirements.

[0055] According to a first aspect of the present invention, see Figure 1 , provides a temperature regulation method for auxiliary frequency regulation equipment of a thermal power plant based on energy storage equipment, comprising the following steps:

[0056] Step S100, obtaining the temperature value inside the control cabinet of the auxiliary frequency modulation equipment of the thermal power plant;

[0057] Step S200, comparing the temperature value with a preset threshold value to obtain a temperature difference;

[0058] Step S300, starting the first device or the second device according to the temperature difference to perform temperature adjustment; wherein, when the temperature difference is less than the first threshold, starting the first device to heat the control cabinet; when the temperature difference is greater than the second threshold, starting the second device to cool the control cabinet.

[0059] In the above-mentioned embodiment, by fixing a plurality of temperature sensors on the inner wall of the control cabinet, the temperature inside the control cabinet can be monitored in real time, and then the monitoring data is sent to the controller. The controller obtains the temperature difference according to the temperature value and the preset threshold value.

When the control cabinet needs to be cooled, only the removable partition needs to be removed, which is very convenient to operate.
