Description

Technical Field

[0001] The utility model belongs to the field of wind power supply management, and in particular relates to a microgrid power supply management system based on wind power hydrogen production. Background Art

[0002] Renewable energy water electrolysis hydrogen production technology is considered to be the most promising hydrogen production method in the future because it can provide clean and pollution-free hydrogen energy and reduce the cost of water electrolysis hydrogen production. In addition, renewable energy hydrogen production is also an important way to increase renewable energy consumption and provide peak load resources.

[0003] As an important part of renewable energy generation, wind power generation cannot be actively controlled like thermal power plants due to its intermittent and volatile characteristics, which brings great challenges to the stable operation of the power grid; at the same time, the operation of many household appliances is inseparable from the supply of electricity. However, the current power supply system still has many defects in the collective management of power supply. When the power consumption of a few residents of the same power supply system under the jurisdiction of the same power system main switch is much greater than that of other residents at a certain moment, if the total power load is too high, the only measure to limit the power consumption of all residents will be to trip the power system main switch, so that the power load of several households is unreasonable and affects the power consumption of all residents within the jurisdiction of the power system main switch, especially affecting some residents who only have basic power needs, such as those who only have lighting power needs, which brings great inconvenience to the lives of residents.

[0035] like Figure 1-Figure 2 As shown, this embodiment provides a microgrid power supply management system based on wind power hydrogen production, including:

[0036] Wind power module 1, power supply management platform, user end and cloud management platform;

[0037] The wind power module 1, the power supply management platform and the user end are electrically connected in sequence; the wind power module 1 and the power supply management platform are both communicatively connected with the cloud management platform 4;

[0040] It can be implemented that the wind power module 1 includes: a wind power generation mechanism, a control terminal and a hydrogen production mechanism;

[0041] The wind power generation mechanism and the hydrogen production mechanism are both electrically connected to the control end, and the control end is also connected to the cloud management platform 4 and the energy storage module 2 .

[0042] It can be implemented that the control end includes a wind network coordinated control submodule 101 and a power setting submodule 102;

[0043] The wind-grid collaborative control submodule 101 is connected to the wind power generation mechanism through the power setting submodule 102; the hydrogen production mechanism and the energy storage module 2 are both electrically connected to the wind-grid collaborative control submodule 101; a communication module is integrated in the wind-grid collaborative control submodule 101, and the wind-grid collaborative control submodule 101 is communicatively connected to the cloud management platform through the communication module.

[0044] A DC / AC power supply module is provided between the wind-grid coordinated control submodule 101 and the energy storage module 2;

[0045] The user power acquisition module collects the power consumption of each user device at a preset time interval, and uploads the collected power consumption to the cloud management platform. When the power consumption is higher than the set frequency of the cloud management platform, the power of the water electrolysis hydrogen production unit is actively increased, thereby reducing the online power of the wind farm; when the power consumption is lower than the set frequency, the power of the water electrolysis hydrogen production unit is actively reduced, thereby increasing the online power of the wind farm; frequency modulation control is implemented in the wind network collaborative control submodule 101 and the power setting submodule 102, and the wind network collaborative control submodule 101 receives the grid dispatching instructions and sends the control instructions to the power setting submodule for frequency modulation. When the power consumption of one or more user devices is abnormal, the corresponding controller sends the power consumption information and positioning information to the cloud management platform through the user power acquisition module, and the power supply platform queries, controls it individually, and performs frequency modulation control;

The control method of the electrolyzer is: when the power consumption is higher than the set frequency of the cloud management platform, the power of the water electrolysis hydrogen production unit is actively increased, and when there is wind disturbance, the electrolyzer current is adjusted to the rated value. At low wind speeds, the electrolyzer is jointly powered by the wind turbine and the power grid. At high wind speeds, the electrolyzer is powered by the excess power after the grid connection. When off-grid operation, the wind turbine independently powers the electrolyzer. When the power consumption is lower than the set frequency, the power of the water electrolysis hydrogen production unit is actively reduced, thereby increasing the online power of the wind farm; the power supply management platform of this embodiment is based on a single or multiple users to carry out targeted control of wind power hydrogen production, and obtains an applicable regulation and management plan, which further increases the practicality and the online power of the wind farm.
