The invention discloses a micro-grid group optimization scheduling method and device, a terminal and a medium, and the method comprises the steps: employing opportunity constraint planning, quantifying the uncertainty of new energy and load in a micro-grid group, setting a confidence level, converting a spinning reserve constraint into a probability constraint form, and carrying out the optimization scheduling of the micro-grid group. And converting the chance constraint plan into a source load output deterministic model by adopting a deterministic equivalent conversion method, establishing an active power distribution network economic dispatching model containing a multi-main-body micro-grid group, and establishing a two-stage hierarchical optimization dispatching model by adopting a target cascade analysis method so as to realize independent optimization of the two-stage hierarchical optimization dispatching model after decoupling. Therefore, the embodiment of the invention can effectively protect the priva
