Abstract

The invention relates to the technical field of independent micro-grids, in particular to an independent micro-grid design system and method based on random robust hybrid optimization, and the systemcomprises a data collection module, an investment planning calculation module and a design scheme output module. The data acquisition module is used for acquiring design factor information; the investment planning calculation module receives the design factor information from the data acquisition module and analyzes the design factor information to generate a design scheme result; and the design scheme output module is used for exporting a design scheme result generated by the investment planning calculation module. According to the independent microgrid two-stage random robust investment planning model provided by the invention, uncertain parameters can be adjusted, so that the uncertainty of renewable energy sources and loads in the system can be fully considered, and then planning schemes under different adjustment parameters are obtained; therefore, an independent microgrid design scheme with more reasonable investment planning can be obtained.

Description

technical field [0001] The invention relates to the technical field of independent microgrids, in particular to a design system and method for independent microgrids based on stochastic robust hybrid optimization. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power grid. In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. Power grid and China Southern Power Grid have 6 large-scale regional power grids across provinces, and have basically formed a complete long-distance transmission grid. [0003] However, power supply in remote areas and islands far from the grid remains a huge challenge due to geographical constraints. The power supply in these areas...
