The invention discloses a provincial and regional two-stage active cooperative control method and system containing high-proportion distributed energy. The method comprises the following steps: acquiring a distributed energy prediction regulation upper limit and output power of each local control region in a regional power grid, tie line transmission power, tie line net exchange power deviation of the regional power grid and an upper-level provincial power grid, and power grid frequency deviation; constructing an active disturbance calculation model of each local control region in the regional power grid, and determining a disturbance type; and according to the disturbance generation position and type, multi-round control batches are determined and corresponding power regulation control is carried out, so that the active balance control requirement is met. According to the method, the actual characteristics of distributed energy access are combined, the rapid adjustment capability of the distributed energy is
