Abstract

Abstract: The electric heating and solid sensible heat thermal storage system is of great significance for the consumption of renewable energy and the clean utilization of energy. The key parameters design and economic analysis of the electric heating and solid sensible heat thermal storage device are important means to improve economic benefits. Therefore, the calculation method of investment and operation cost of electric heating and solid sensible heat thermal storage device is presented in this paper. By comparing the cost of different heating methods, the economics of electric heating and solid sensible heat thermal storage device were analyzed. Meanwhile, the influence of the utilization coefficient of the off-peak power on the economy of the electric heating and solid sensible heat thermal storage device was studied. Finally, a case study is used to verify the rationality and correctness of the economic evaluation method proposed in this paper. The research content of the paper can provide reference for users to choose the electric heating and solid sensible heat thermal storage device.

Key words: solid electric heating and sensible heat storage, off-peak electric thermal storage, economic analysis
