An urban power distribution network loss reduction optimization method based on a load prediction model comprises the steps of building a mathematical model for the comprehensive optimization of powerdistribution network loss, namely, the mathematical model for the comprehensive optimization of power distribution network loss is responsible for comprehensively considering the network loss, the switching times, the energy efficiency load optimization management and reactive compensation voltage deviation indexes of a distributed power distribution network; establishing a constraint conditionsof the mathematical model for the comprehensive optimization of the urban power distribution network loss; and adopting an improved harmony search algorithm to solve the mathematical model for the comprehensive optimization of the urban power distribution network loss, wherein the solved global optimal solution is the minimum value of the loss of the power distribution network under the constraintcondition within a certain range. According to the present invention, the power personnel can adjust the power grid according to each parameter in the global optimal solution, thereby achieving the purpose of reducing the consumption of the power distribution network.
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 ...
