Operation control method of wind power generation and hydrogen production hydrogen storage system

Abstract

The invention relates to an operation control method for a wind power generation and hydrogen production and storage system, and relates to the technical field of new energy wind power generation and hydrogen production. The rectifier on the fan side of the wind farm is connected to the grid-side inverter; a DC / DC supercapacitor is connected to the DC bus, and the hydrogen production and storage system is connected behind the supercapacitor; the photovoltaic system is connected to the DC in front of the supercapacitor through DC / DC The bus connection, as the power compensation unit of the wind farm, also includes a power coordination control module and a monitoring module. It mainly solves the problems of wind power generation and hydrogen production and hydrogen storage systems, such as poor peak shaving capability, uneven hydrogen production, and short service life of equipment. It has system peak shaving It has strong capacity, can meet the requirements of evening peak load, can ensure smooth hydrogen production, extend equipment life, and can be flexibly connected to the grid under the premise of ensuring the purity of hydrogen production, and has high energy utilization. This operation control method further improves energy efficiency. utilization rate.

Description

technical field [0001] The invention relates to the technical field of new energy wind power generation and hydrogen production, in particular to an operation control method of a wind power generation and hydrogen production hydrogen storage system. Background technique [0002] With the rapid development of modern society, the demand for energy has reached a stage of rapid growth. Not only is there a shortage of electricity and energy, but the cooling and heating systems also cause serious air pollution. Issues such as energy security and matching supply and demand have become increasingly prominent. Resources such as scenery have begun to attract people's attention. The randomness, volatility, and irregularity of wind energy will make it difficult to connect wind power to the grid, which will have a large impact on the grid and a high amount of wind curtailment. The wind power generation system cannot meet the requirements of the evening peak load. Enhancing the peak-s...
