The invention discloses a scheduling method for a new energy power system in multiple regulation domain operation modes, and belongs to the technical field of renewable energy power generation and a new energy power grid. The method combines operational status information of each operating domain of a power system and comprehensively considers the effective demand of each operating domain and thefeasibility of energy scheduling, thereby completing the scheduling. The scheme realizes the synergy of multiple sources to the multi-operation domain information of the power system, can adaptively select the optimal unit combination, and improves the operation stability of the power system in multiple operation domains.
