Abstract

The embodiment of the invention discloses a power distribution network scheduling method and a storage medium. The method comprises the following steps: building a renewable energy utilization rate maximum model according to an output power model of a wind turbine generator and an output power model of a photovoltaic unit; establishing a net load peak-valley difference minimum model according to the net load model of the power distribution network and the power of an electric vehicle cluster; establishing a net load variance minimum model according to the output power model of the wind turbinegenerator, the output power model of the photovoltaic unit and the net load model of the power distribution network; establishing a power supply side comprehensive cost minimum model according to theelectricity purchasing cost from the power distribution network to the large power grid and the operation and maintenance cost of an energy storage device; establishing a tie line power fluctuation minimum model according to the power of a tie line; and scheduling the power distribution network according to the renewable energy utilization rate maximum model, the net load peak-valley difference minimum model, the net load variance minimum model, the power supply side comprehensive cost minimum model and the tie line power fluctuation minimum model, thereby realizing reasonable scheduling of the park power distribution network.

Description

technical field [0001] The embodiments of the present invention relate to the field of park distribution network scheduling, and in particular, to a distribution network scheduling method and a storage medium. Background technique [0002] With the development of science and technology, the growth of the national economy and the country's great emphasis on the concept of environmental protection, in order to achieve energy conservation and emission reduction and develop a low-carbon economy, electric vehicles using renewable energy as a power source have ushered in large-scale development and use. . [0003] As a new type of electric load, electric vehicles, especially with the sharp increase in their number, the load generated by charging electric vehicles connected to the distribution network will aggravate the peak-to-valley load difference of the distribution system, reduce the utilization rate of system components, and increase the Instability of large power grids. Th...
