Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for optimizing loss reduction of an urban distribution network based on a load forecasting model. Background technique [0002] With the increasing scarcity of power resources since the 21st century, improving energy efficiency and saving resources has become a new requirement for China's social and economic development. At the same time, the excessive loss of the distribution network will seriously affect the economic benefits of the power company and cause a waste of social resources. The power system itself is a large energy consumer, and the urban distribution network is the main part of the energy loss of the power system. The realization of energy saving and consumption reduction of the distribution network plays a decisive role in improving the economic efficiency of power supply enterprises and achieving the target profit. Due to the fast growth of load ...
