Embodiment 1

[0049] see Figures 1 to 3 The core of the present invention is to provide a hydrogen power system based on automatic power generation control, including a power dispatching module, a management and control module, a power transformation and distribution module, a hydrogen power generation system and a power storage module; the power dispatching module is electrically connected to the management and control module and the power grid. ; The control module is electrically connected to the power transformation and distribution module, the hydrogen power generation system, the power grid and the power storage module; the power transformation and distribution module is electrically connected to the hydrogen power generation system, the power storage module and the power grid.

[0050] The power dispatching module is used to collect the power demand information of grid operation and send it to the management and control module. When the management and control module judges that ther...

Embodiment 2

[0071] Another core of the present invention is to provide a method for operation and inspection of a hydrogen power system based on automatic power generation control, including the hydrogen power system based on automatic power generation control of Embodiment 1, using the following steps:

[0072] S1: The management and control module monitors the state of the power storage module group M and the power storage module group N, and controls the charging and discharging between the power grid and the power storage module through the power transformation and distribution module, so that the power storage module SOC is 85%±5%;

[0073] Specifically, when the power storage module supplies power to the hydrogen power generation system and the hydrogen storage module, the management and control module monitors that the state-of-charge SOC of the power storage module is lower than 70%, and controls the bidirectional converter of the power storage module to charge the power from the gr...

Abstract

The invention discloses a hydrogen power system based on automatic power generation control. The hydrogen power system comprises a power dispatching module, a management and control module, a power transformation and distribution module, a hydrogen power generation system and a power storage module, the power dispatching module is electrically connected with the management and control module and the power grid; the management and control module is electrically connected with the power transformation and distribution module, the hydrogen power generation system, the power grid and the power storage module; the power transformation and distribution module is electrically connected with the hydrogen power generation system, the power storage module and the power grid; the power dispatching module is used for collecting power demand information of power grid operation and sending the power demand information to the control module; the management and control module controls the power transformation and distribution module to transmit off-peak electricity and abandoned electricity of the power grid to the power storage module for storage; when the management and control module judges that the power grid needs peak regulation and frequency modulation according to the power demand information, the power storage module is controlled to supply power to the power grid, the hydrogen power generation system is controlled to generate power and supply power to the power grid, and after the hydrogen power generation system generates power stably, the power storage module is controlled to stop supplying power to the power grid.

Description

technical field [0001] The invention belongs to the technical field of power grid peak regulation and frequency regulation, and in particular relates to a hydrogen power system based on automatic power generation control and an operation inspection method thereof. Background technique [0002] The growth rate of my country's electricity demand has slowed down, and the randomness and volatility of renewable energy have impacted the power grid, resulting in increased peak and frequency regulation pressure on the power grid, and the power supply of renewable energy needs auxiliary systems for stability adjustment. [0003] Usually in the power system, the power demand of each power plant is constantly changing. In order to maintain the active power balance and maintain the system frequency stability, the power generation department needs to change the power supply capacity accordingly to adapt to the changes in the power grid. At present, peak regulation and frequency regulatio...
