The invention relates to an active power distribution network optimization scheduling model and method considering information system uncertainty. The method specifically includes the following stepsthat: a power generation transfer factor which can express a relationship between renewable energy power variation and flexibility provided by an upper-layer power grid and flexibility provided by a controllable load is constructed; a power distribution network conventional optimal power flow model is provided, the optimal solution of the power distribution network conventional optimal power flowmodel is solved, and a sensitivity factor matrix which can express a linear relationship between a node injection power variation quantity and the real part and imaginary part of node voltage, a branch power flow active power variation quantity and a reactive power variation quantity; and an opportunity constraint-based optimal power flow model is constructed based on the above steps, and the opportunity constraint-based o
