Description

technical field [0001] The invention discloses a multi-objective fuzzy-optimized multi-energy economic scheduling method in an active distribution network environment, which is especially suitable for the active distribution network environment with large-scale intermittent power supply access, and belongs to the technical field of power system automation. Background technique [0002] Due to the large-scale intermittent energy access in the active distribution network environment, the multi-energy optimization in the active distribution network presents the characteristics of multi-objective, multi-constraint and strong uncertainty. Traditional optimization methods cannot optimize multiple objectives at the same time, often only provide a single decision-making scheme, and cannot provide sufficient decision-making support for decision-making schedulers. At the same time, the traditional stochastic optimization method relies too much on the probability density function when ...
