The invention discloses a method for monitoring an intelligent distributed wind power generation system with adjustable voltage and power. The method includes the following steps: S1. a wind generation device monitoring module real-time acquiring operation data of a wind generation device, storing the data, and real-time acquiring demand for load power within the wind power generation system; conducting first-order filtering on an active power PWO that is sent by the wind generation device and outputting an expected active power PWf of the wind generation device; S2. acquiring voltage information at grid-connected points, at the same time based on a scheduling instruction of a large power grid, determining demand for an active or reactive power output of the wind power generation system; real-time detecting and acquiring a SOC of a battery module; S3. processing the acquired information about the wind generation device, a power grid and batteries to obtain an expected output power reference quantity PEss=[delta] P1+[delta]PB of an energy storage system, wherein the [delta] P1 is a difference value between PWO and PWf, setting a discharge zone of the energy storage system, and establishing a SOC layered control strategy; S4. with the demand for active and reactive power output, the current SOC layered control strategy, the current demand for the load power within the wind generation system, and the fact that the wind generation device may output an active and reactive power as restraining conditions, implementing optimized operation of the wind generation system.
