Abstract

The invention relates to a control method and a system of a regional heat storage station. The method comprises the steps of: determining the heat storage power of a regional heat storage station according to the predicted value of an electric load demand of a regional power grid user; and dividing the rigid heat storage device and the flexible heat storage device in the regional heat storage station according to the heat storage power of the regional heat storage station, and controlling the rigid heat storage device and the flexible heat storage device to store heat. According to the technical scheme, the configuration and scheduling problems of the sub heat storage devices in the regional heat storage station are optimized, so that the regional heat storage station can participate in the peak regulation and frequency modulation work of the regional power grid more efficiently, the energy utilization rate of the regional power grid is increased more effectively, and the system operation cost is reduced.

Description

technical field [0001] The invention relates to the field of new energy consumption, in particular to a control method and system for a regional heat storage station. Background technique [0002] At present, there are contradictions between the rapid development of wind and solar power stations and the increasingly serious abandonment of wind and light. Among them, the abandonment of wind means that the wind power generator does not supply power to end users during power generation, and the abandonment of light means that the power generation of photovoltaic power plants is greater than that of electricity. The sum of the maximum power transmitted by the system and the power consumed by the load. [0003] The development speed of wind power has exceeded the development status of the power grid and electricity load, leading to the increasingly prominent issue of wind curtailment. The national curtailment of wind power has reached 17.5 billion kWh, and the curtailment rate of...
