The invention discloses a micro-grid optimization scheduling method and system based on RBF-ISBO. A micro-grid system is constructed by taking micro-grid economic benefits and carbon reduction as targets; carrying out equipment modeling on renewable energy sources in the micro-grid system by adopting an RBF neural network to obtain an equipment model; by taking the minimum power generation cost of the micro-grid as an optimization target, on the premise of meeting the rated output power constraint conditions of wind-solar power generation, a diesel generator and energy storage equipment of the micro-grid, optimizing the equipment model established by the RBF neural network by using an improved SBO algorithm to obtain a power supply combination of micro-grid equipment; and according to the power supply combination of the micro-grid equipment, calculating the corresponding micro-grid power generation cost, performing sorting according to the power generation cost, finding out the optimal power supply combination to enable the power generation cost of the micro-grid equipment to be minimum, and realizing micro-grid optimal scheduling. After ISBO optimization scheduling is adopted, the power generation cost of the micro-grid is reduced by 16.7%-21.2%, and better convergence and robustness are achieved.
Description
technical field [0001] The invention belongs to the technical field of microgrid scheduling, and in particular relates to a microgrid optimal scheduling method and system based on RBF-ISBO. Background technique [0002] In recent years, with the increasing demand for electricity and the rising cost of traditional power generation and the falling cost of renewable energy generation, renewable energy has received more and more attention, especially the new power grid represented by microgrid. In addition to considering the cost of power generation, due to the environmental friendliness of renewable energy power generation and the rapid development of the concept of microgrids, the problem of optimal scheduling of microgrid energy has become a very valuable research topic. [0003] At present, the basis of microgrid energy optimal dispatch is to establish an optimal model for each device. Common renewable resource equipment models include mechanism models, parameter identifica...
