The invention provides a multi-type power supply time sequence planning method and system under a long time scale, and the method comprises the steps: taking the cost minimization as a target, and obtaining a target function; the objective function at least comprises power supply investment cost and operation cost in a planning period; determining a first constraint condition; the first constraint condition is at least related to output characteristics and planned capacity of a generator set, and the generator set is a multi-type power supply; determining a second constraint condition; the second constraint condition is at least related to electric power and electric quantity balance and energy storage characteristics of energy storage equipment; based on the first constraint condition and the second constraint condition, solving the objective function to obtain constant volume construction schemes of the generator set and the energy storage equipment at different time nodes in the planning period; medium-and
