Abstract

With the rapid development of society and the continuous growth of energy demand, the efficient and reliable operation of power system as the infrastructure of modern society has become particularly important. The loss of electricity in the transmission and distribution process not only reduces the efficiency of energy use, but also increases the cost of electricity, which has a negative impact on the economy and the environment. Therefore, it is of great significance to study and implement effective strategies to reduce power loss for improving energy efficiency of power system and promoting sustainable development of energy. This paper first summarizes the basic types and principles of power loss, including transmission line loss, transformer loss, distribution network loss and load loss, etc., and then analyzes the current situation and influencing factors of domestic power loss, such as the structure and configuration of power system, technical performance of power equipment, load characteristics and environmental and climatic conditions. On this basis, a series of strategies and measures to reduce power loss are proposed, including optimization of power grid structure and configuration, improvement of equipment energy efficiency and replacement, smart grid and dynamic scheduling, implementation of demand side management and load control, and utilization of clean energy and energy storage technologies. Finally, the paper summarizes the research results, and points out that the implementation of these comprehensive measures can significantly reduce the power loss of the power system, improve the efficiency of energy utilization, and have a far-reaching impact on ensuring energy security, promoting environmental protection and economic development.
