The invention discloses an energy storage power station and system special for power grid peak regulation, and relates to the technical field of power grid peak regulation. Large-scale, high-density and high-grade heat energy storage is completed based on cooperation between the salt heat storage subsystem and the independent phase change heat storage subsystem which is independently packaged and capable of automatically charging and discharging heat, and the process of charging heat to the independent phase change heat storage subsystem and taking heat from the independent phase change heat storage subsystem for power generation is efficiently completed in the heat storage circulation stage and the heat release circulation stage. Meanwhile, the valley electricity part which is not consumed by the power grid serves as a second original heat input source and is directly connected to the independent phase change heat storage subsystem to reversely store heat, and the energy storage efficiency is improved; the h
