Description

Technical Field

[0001] The present invention relates to a carbon emission control system and method, and in particular to a carbon emission control system and method for distributed energy. Background Art

[0002] Energy consumption has transitioned from the original decentralized energy consumption represented by firewood to centralized energy consumption. The centralized energy system has built the first generation of energy systems with the "large capacity, high parameters, and long-distance transmission" model under the scale benefit. In order to ensure supply capacity and avoid power outages during peak hours, centralized energy systems are generally configured with rent, so that many generators are in a restricted state for most of the year, resulting in a waste of power plant investment. Clean energy natural gas has a very high supply load in winter and a very low supply load in summer, resulting in a low average annual pipeline network utilization rate.

[0003] Efficiency and emergency response are the biggest challenges of centralized energy systems. Distributed energy refers to the comprehensive utilization and supply system of energy distributed at the user end, with natural gas and renewable energy (photovoltaic, wind energy, geothermal energy, etc.) as the main primary energy. The development of distributed energy systems can alleviate these problems to a certain extent. With the implementation of coal-to-gas conversion and the adjustment of energy structure, my country's natural gas and renewable energy are developing rapidly. In order to improve the utilization rate and comprehensive utilization efficiency of natural gas pipelines and make full use of renewable clean energy such as wind power and solar energy, which are decentralized in themselves, various forms of distributed energy systems have been vigorously developed. However, under the current situation of multiple energy supplies, how to make the system's carbon dioxide emissions meet carbon emission requirements has become a key research direction in this industry. Summary of the invention

[0005] To achieve the above objectives, the present invention discloses a carbon emission control system for distributed energy, including a distributed energy system and a service terminal, wherein the service terminal is connected to the distributed energy system, and the service terminal controls the distributed energy system according to user demand.

[0014] When the carbon dioxide emissions of the distributed energy system are lower than the carbon emission threshold, and the electricity output by the distributed energy system exceeds the user's electricity demand, the excess electricity will be output to the carbon capture system and used for carbon capture.
