Large-scale wind power storage system and method

Abstract

The invention provides a large-scale wind power storage system, which comprises a hydrogen production and hydrogen storage system, a fuel cell power generation system and a wind power plant energy management system. The wind power plant energy management system is connected with a wind power plant, a power grid, the hydrogen production and hydrogen storage system and the fuel cell power generation system; the wind power plant is connected with the power grid, the hydrogen production and hydrogen storage system and the fuel cell power generation system; and the hydrogen production and hydrogen storage system is connected with the fuel cell power generation system. The invention also provides a large-scale wind power storage method. The wind power plant energy management system serves as a control system of the whole wind power plant and is responsible for operation management and energy control of the wind power plant; the wind power plant realizes wind power generation to supply power to the power grid; when wind power is abundant, surplus power is provided for the hydrogen production and hydrogen storage system for water electrolysis hydrogen production and hydrogen storage; and when power is not sufficient, the stored hydrogen is converted into electric energy through the fuel cell power generation system, thereby realizing large-scale wind power storage. The system and method improve wind utilization efficiency and prevent huge loss.

Description

technical field [0001] The invention relates to the technical field of wind power storage, in particular to a large-scale wind power storage system and method. Background technique [0002] my country's wind power is developing rapidly. By the end of 2012, the installed capacity of wind power reached 75.32 million kilowatts, and the annual power generation was 100.4 billion kilowatt-hours, ranking first in the world. The wind power equipment industry has also made great progress, and its technology has gradually surpassed the world's advanced level. The development of wind power has achieved world-renowned achievements. [0003] Because wind energy cannot be stored in large quantities, at present, battery technology is often considered in solving wind power storage. But batteries can only store a small amount of wind energy. Wind energy cannot be stored in large quantities, the utilization efficiency of wind is low, and it is difficult to absorb wind power, which leads to ...
