Renewable energy driven zero-carbon efficient distributed energy supply system and operation method

Abstract

The invention discloses a renewable energy source driven zero-carbon efficient distributed energy supply system and an operation method, the system uses renewable energy sources such as wind and light to generate power, and electric energy is provided for users; hydrogen is produced by electrolyzing water and then is conveyed to hydrogen storage equipment to meet the hydrogen load requirement; the electric drive compression heat pump is used for supplying cold and heat, and the thermochemical energy storage device is used for storing and recycling solar heat. For the absorption heat pump system, high-temperature steam generated by the thermochemical heat storage system and high-temperature hot water generated by a fuel cell in the hydrogen energy storage system are used as combined driving heat sources, so that the energy utilization efficiency of the system is improved. According to the system, renewable clean energy is completely utilized, the system has the characteristics of zero carbon emission, full recycling of multi-source and multi-grade waste heat in a distributed energy system and efficient gradient utilization of energy, and four-combined supply of cold, heat, electricity and hydrogen can be realized for users.

Description

technical field [0001] The invention relates to the technical field of distributed energy systems, in particular to a renewable energy-driven zero-carbon and efficient distributed energy supply system and an operating method.
