Abstract
Under the background of carbon peaking and carbon neutralization proposed by China, the development of energy storage technology is imperative. The heat consumption of building central heating is large, which can be used as an important means of load side energy storage. The mathematical model of the central heating system is established, the optimal simulation of the regenerative temperature stratified water tank in the heating system is carried out, and the optimal structure of the temperature stratified water tank is obtained. The heating power of the fully mixed water tank is compared with the indoor maintenance temperature, and the power consumption of the primary pump is reduced by 8.5%. The energy utilization rate of the heating system is high and has high energy-saving potential.
Highlights
With the global climate change problem becoming increasingly prominent, peak carbon dioxide emissions and carbon neutrality have become hot topics all over the world. e annual greenhouse gas statistics report published on the website of the US Environmental Protection Agency is based on national energy use, agricultural data, and other statistical data and summarizes the greenhouse gases produced by all anthropogenic emission sources in the United States, forming the Catalogue of Greenhouse Gas Emissions and Carbon Sinks. e catalogue shows that the peak of carbon dioxide emissions in the history of the United States appeared in 2007, when the total amount of greenhouse gases emitted by the United States was equivalent to 7.25 billion tons of carbon dioxide
Accelerating the pace of carbon emissions is conducive to guiding green technology innovation, accelerating the development of green and low-carbon industries, forming new growth points in the fields of renewable energy, green manufacturing, and carbon capture and utilization, and improving the global competitiveness of industries and economies. e challenge of “double carbon goal” is very arduous. e road to zero carbon in the first-developing countries is still quite long, and there is no shortcut in the second-developing countries
In 2004, according to the mathematical model, a central heating system model was established by Zaheeruddin, and the model was simulated by MATLAB
Summary
With the global climate change problem becoming increasingly prominent, peak carbon dioxide emissions and carbon neutrality have become hot topics all over the world. e annual greenhouse gas statistics report published on the website of the US Environmental Protection Agency is based on national energy use, agricultural data, and other statistical data and summarizes the greenhouse gases produced by all anthropogenic emission sources in the United States, forming the Catalogue of Greenhouse Gas Emissions and Carbon Sinks. e catalogue shows that the peak of carbon dioxide emissions in the history of the United States appeared in 2007, when the total amount of greenhouse gases emitted by the United States was equivalent to 7.25 billion tons of carbon dioxide. Under the background of large-scale development of new energy, how to solve the problems and challenges in grid-connected consumption is the key factor to achieve the goal of “double carbon.”. Energy storage technology is an important technical means to effectively relieve the pressure of large-scale renewable energy grid connection, which can smooth the intermittent renewable energy power generation output and improve the frequency modulation and peak shaving capability of thermal power units, so it has been widely valued [5]. E difference between the power generated by renewable energy and the system load is partly traded with the large power grid, which can reduce wind and light abandonment and improve the economy of the system It plays an important role in building a clean, low-carbon, safe, and efficient modern energy system and has social practical significance. The energy storage system on the load side has great potential, and the development of energy storage on the load side has become an irreversible trend
