The invention discloses a determination method, a scheduling method and a scheduling system for regulatable capability of an electric vehicle cluster. The determination method comprises the following steps: at each scheduling moment, according to the residual charging duration, the current SOC and the target SOC of each EV, calculating the available charging/discharging capacity and the available charging/discharging power of an electric vehicle at each scheduling moment by using a single electric vehicle adjustable capability evaluation model; superposing the available charging/discharging capacity and the available charging/discharging power of each electric vehicle at each scheduling time, and determining the adjustable capability of the electric vehicle cluster at each scheduling time period; and based on the power grid demand and the adjustable capability of the electric vehicle cluster at each moment, carrying out power distribution on each electric vehicle in the electric vehicle cluster at each moment in the scheduling time period by taking supply and demand balance as a target. According to the invention, by adopting the scheme of the invention, the regulation and control capability of the EV cluster can be accurately evaluated, the power and capacity boundary of the EV cluster can be updated in real time by carrying out reasonable power distribution on the EVs in different states, and the scheme has important significance in balancing the load power and making a real-time scheduling plan for a power grid.
