Abstract

The invention discloses a micro-grid planning and capacity allocation method based on multi-objective optimization. The method is characterized in that the method comprises the steps of (1) setting the operation mode of a micro-grid, wherein the operation mode of the micro-grid comprises an independent mode and a grid-connected mode; (2) inputting basic data which comprise the system condition, electrovalence parameters, load parameters, photovoltaic parameters, wind electricity parameters and storage battery parameters; (3) pre-processing the basic data; (4) optimizing a distributed power supply and an energy storage system. According to the micro-grid planning and capacity allocation method, distributed power supply capacity and energy storage system capacity in micro-grid planning can be solved jointly, and optimizing allocation can be carried out at the same time.

Description

Technical field [0001] The invention relates to a micro-grid planning and capacity configuration method, belonging to the technical field of micro-grids. Background technique [0002] The proposal of microgrid technology is closely related to the application and development of distributed generation (DG) technology. Compared with traditional power sources that rely on long-distance transmission and distribution, distributed generation technology has diversified energy forms and high energy efficiency. And environmental friendliness. The flexible and decentralized installation location of the distributed power generation system perfectly adapts to the decentralized power demand and resource distribution, and delays the huge investment required for the upgrade of the transmission and distribution network. At the same time, it and the large power grid are mutually backup and provide power supply Reliability is improved, effectively solving many potential problems of large-scale cen...
