Multi-energy complementary wind-solar-hydrogen storage integrated renewable energy system

Abstract

The invention relates to a multi-energy complementary wind-solar-hydrogen storage integrated renewable energy system which comprises wind power generation equipment (1), solar photovoltaic power generation equipment (2), energy storage equipment (3), water electrolysis hydrogen production equipment (5), a hydrogen storage device (7) and a hydrogen conveying pipe network system (8) connected with the hydrogen storage device (7). The wind power generation equipment (1), the solar photovoltaic power generation equipment (2), the energy storage equipment (3) and the water electrolysis hydrogen production equipment (5) are connected through an internal power network (4), are not connected with an external power grid and operate in an isolated network mode. By establishing the wind-solar-hydrogen storage integrated hydrogen production and supply system with the isolated network operation capability, clean green power is converted into high-quality hydrogen with wider application, and the green energy development level is improved.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a multi-energy complementary wind-solar hydrogen-storage integrated renewable energy system. Background technique [0002] Increasing the development of renewable energy such as wind power and photovoltaic power generation is an objective requirement to solve my country's energy demand, and it is also a realistic requirement to reduce my country's fossil energy consumption, dependence on fossil energy consumption and carbon dioxide emission intensity. However, due to the disadvantage that electric energy cannot be stored on a large scale for a long time, improving the consumption level of renewable energy and promoting the development of renewable energy has always been an important problem facing my country's power grid construction and energy development. Contents of the invention [0003] The purpose of the present invention is to provide a multi-energy ...
