The invention discloses an energy storage and heat supply system and method with a frequency modulation function. The system comprises a molten salt pond, a molten salt pump, an electric heating exchanger and a water vapor heating module. An outlet of the molten salt pond is connected to an inlet of the molten salt pump, an outlet of the molten salt pump is connected to a first inlet of the electric heating exchanger, an outlet of the electric heating exchanger is connected to a first inlet of the water vapor heating module, and a first outlet of the water vapor heating module is connected to an inlet of the molten salt pond. A system composed of the fused salt pond, the fused salt pump, the electric heating exchanger and fused salt in the water vapor heating module is called a fused salt system. After a heat user suddenly breaks down, redundant heat can also be stored through the heat storage system, and the unit adjusting time is given; after a certain generator set breaks down, heat is released through the
