E-book Efficient Energy-Saving Control and Optimization for Multi-Unit Systems
The use of fossil energy sources such as coal, natural gas and oil is a major source of carbon dioxide. In order to reduce the use of fossil energy, we need green and efficient energy production for power generation systems; for energy consumption systems, we need energy conservation and high energy efficiency. The International Energy Agency (IEA) believes that “energy efficiency is the first fuel” and will make the greatest contribution to the climate goals of the Paris Agreement. Energy efficiency peak is the technical support for “carbon peak”. The purpose of electrical control and automation control is to replace labor, improve production and precision, and create a safe and comfortable environment. In the case of completing the same task, reducing energy consumption and improving energy efficiency are also one of its important purposes. In addition to saving production costs, energy saving can also improve the living environment of human beings and reduce carbon dioxide emissions. During the COVID-19 pandemic, our random survey of 501 secondary water supply pumping stations in an international metropolis (with a population of more than 20 million) showed that the average power waste is 54%. That is to say, if the energy efficiency optimization design method and the energy efficiency optimization control method are adopted, the power consumption of 200,000–300,000 sets of secondary water supply pumping stations in the city can be reduced by 54%
