Abstract
Provided is a molten salt energy storage (MSES) electric heating system, including: an effect module configured to analyze a heat storage effect of each of different molten salt (MS) components; a cost module configured to analyze a cost consumption of each of the different MS components; an environmental protection module configured to analyze an environmental protection condition of each of the different MS components; a proportion module configured to determine a proportion of each of the different MS components; a demand module configured to calculate an actual demand; and a scheduling module configured to schedule stored heat. This system improves the efficiency of MSES.
Claims9
A molten salt energy storage (MSES) electric heating method, comprising:
- acquiring a geographical environment of MSES, analyzing a heat storage effect of each of a plurality of molten salt (MS) components according to the geographical environment of the MSES, and labeling the heat storage effect as a component effect AXm, wherein m is a serial number of each of the plurality of MS components;
- analyzing a cost consumption of each of the plurality of MS components according to the geographical environment of the MSES, and labeling the cost consumption as ACm;
- analyzing an environmental protection condition of each of the plurality of MS components according to the geographical environment of the MSES, and labeling the environmental protection condition as AHm;
- calculating suitability of each of the plurality of MS components according to the component effect AXm, the cost consumption ACm and the environmental protection condition AHm, determining a proportion of each of the plurality of MS components according to the suitability of each of the plurality of MS components, and labeling the proportion as an MS component proportion;
- acquiring an actual heating demand, and calculating an actual demand condition;
- and
- scheduling stored heat according to the actual demand condition, which specifically comprising:
- acquiring an actual heating supply based on the actual demand condition, calculating a difference between the actual heating supply and the actual demand condition, and labeling the difference between the actual heating supply and the actual demand condition as an actual heating difference;
- acquiring a power supply condition in heating time based on the actual heating difference, and determining whether the power supply condition is in a peak period;
- feeding heat of the actual heating difference to a power grid through a heat conversion device for power generation if the power supply condition is in the peak period;
- and
- feeding the heat of the actual heating difference to an energy storage battery through the heat conversion device for electricity storage and next electric heating if the power supply condition is not in the peak period.
