The invention discloses a capacity configuration method and device suitable for a wind-light-water energy storage system. The method comprises the following steps: establishing a system model of the wind-light-water energy storage system; taking the minimum total investment cost of the energy storage system, the minimum storage battery capacity, the maximum smooth fluctuation power and the maximum clean energy utilization rate as objective functions, and establishing corresponding constraint conditions; according to the system model, the objective function and the constraint condition, calculating by adopting a meta-heuristic algorithm to obtain the annual configuration capacity of the wind-light-water energy storage system; according to the annual configuration capacity, a multi-objective evolutionary algorithm is adopted to calculate an optimal Pareto subspace, and the daily start-stop number of the wind-light-water energy storage system is obtained; according to the annual configuration capacity and the da
