Multi-stage stochastic programming method and device for alternating-current and direct-current independent micro-grid group

The invention relates to a multi-stage stochastic programming method and device for an AC/DC independent micro-grid group, and the method comprises the steps: constructing a multi-stage stochastic programming model of the AC/DC independent micro-grid group based on the investment cost and comprehensive operation cost of a sub-micro-grid at different stages, and determining the constraint condition of the stochastic programming model; and solving the stochastic programming model by adopting a preset solver, and taking a solving result as an optimal planning scheme of the micro-grid group. According to the invention, the planning of the AC/DC hybrid micro-grid is more reasonable. 本发明涉及一种交直流独立微电网群多阶段随机规划方法和装置，其中，方法包括：基于子微电网不同阶段投资成本和综合运行成本构建交直流独立微电网群多阶段的随机规划模型，并确立所述随机规划模型的约束条件；采用预设求解器对所述随机规划模型进行求解，并将求解的结果作为微电网群最优规划方案。本发明使得交直流混合微电网的规划更为合理。
