Zero-carbon micro-grid system for multi-storey and below residential building community

Abstract

The invention provides a zero-carbon micro-grid system of a multi-storey and below residential building community. The zero-carbon micro-grid system comprises a photovoltaic power generation system, a wind power generation system, a kitchen waste and excrement special pipeline system, a kitchen waste anaerobic fermentation treatment station, an internal combustion engine power station, an excrement treatment station, a household energy storage system, an intelligent household electrical appliance system, a community substation and a smart energy management system. By implementing the technical scheme of the system, the problems that household distributed new energy is small in installation capacity, poor in system stability and incapable of achieving self-sufficiency of electric power in residential districts can be effectively solved, meanwhile, the utilization efficiency of electric energy in resident life is improved, and carbon emission caused by electricity consumption of urban and rural residents in life is integrally reduced. In addition, the problems of kitchen waste treatment and excrement resource utilization in the daily life of residents can be solved, the cost input of treating the type of waste by the outside world is reduced, carbon emission is further reduced, the benefit of source utilization is brought, and the male goal of '30 carbon peak and 60 carbon neutralization' in China is assisted.

Description

technical field [0001] This application relates to the technical field of low-carbon environment, specifically a zero-carbon micro-grid system for multi-storey and below residential buildings. Background technique [0002] Residents need to consume electricity in their daily life, and most of this electricity comes from fossil fuels. Therefore, the electricity consumption of urban and rural residents, which accounts for about 14% of the electricity consumption of the whole society in the country, is a component of carbon emissions that cannot be ignored by the whole society. In addition, the whole society A large amount of non-recyclable garbage generated in the daily life of social residents, especially kitchen waste, requires a large amount of external input such as collection, transportation, sorting, and landfill treatment to digest, and also produces a large amount of carbon emissions. To achieve the goal of "30 carbon peaks and 60 carbon neutrality", how to solve the a...

Problems solved by technology

Although renewable energy is widely used in residential buildings in the form of distributed photovoltaics and distributed wind power, due to factors such as small installation capacity, poor system stability, lack of maintenance and low system efficiency, it can only be used as an auxiliary power supply to decorate residential buildings, and cannot be used as a real energy source. Support and offset residential electricity needs

A small number of private single-family villas can achieve self-sufficiency in electric energy through household solar storage systems, but civil single-family buildings are not universal in cities and towns in my country
