Abstract

The invention provides a wind power energy storage system, which comprises a wind power unit, a rectification unit, a confluence cabinet, an energy storage battery system and an energy storage converter, and is characterized in that the rectification unit is connected with the wind power unit and the confluence cabinet, and is used for carrying out AC-DC conversion on the output current of the wind power unit; the confluence cabinet is also respectively connected with the energy storage battery system and the energy storage converter, and is used for switching on or switching off the current output to the energy storage battery system and the energy storage converter; the energy storage converter is used for performing DC-AC conversion on the current output by the confluence cabinet and then outputting the current to a load; the system also comprises a control unit which is connected with the confluence cabinet, the rectification unit, the energy storage battery system and the energy storage converter, and is used for controlling the wind power unit to charge the energy storage battery system and / or controlling the wind power unit to discharge a load connected with the energy storage converter according to the output power of the wind power unit and the residual electric quantity of the energy storage battery system. The electric energy generated by the wind power unit is distributed, and the resource utilization rate is improved.

Description

technical field [0001] The present application relates to the technical field of wind power energy storage, and in particular, to a wind power energy storage system. Background technique [0002] With people's attention to environmental protection, industries such as new energy, smart energy and energy storage have achieved rapid development. Wind power energy storage control system is a hot field of battery energy storage utilization, which can supply power to user-side loads and charge batteries. [0003] In the existing wind power energy storage control system, when the battery is not fully charged, the wind power energy storage control will give priority to charging the battery, and only supply power to the load when the battery is fully charged. The distribution of electric energy output by the prior art is unreasonable, resulting in a low utilization rate of resources. SUMMARY OF THE INVENTION [0004] The present application provides a wind power energy storage sy...
