The invention provides a system and method for power station and compressed air combination energy storage power generation. The system for power station and compressed air combination energy storage power generation comprises a heat power station, a wind power station, a biomass power station, a compressed air energy storage system, a power grid system and a demand load system. The heat power station, the wind power station and the biomass power station are connected with the compressed air energy storage system, and the compressed air energy storage system is connected with the power grid system. The demand load system is connected with the heat power station, the wind power station, the biomass power station, the power grid system and the compressed air energy storage system. According to the technical scheme, on the conditions of not affecting power grid peak regulation performance, clean energy is introduced, and the clean energy utilization rate is improved.
