英文摘要:

      Solid electric heat storage technology converts the off - peak electricity into the heat energy, which is of great significance to the severe electric peak load regulation of the power grid,the utilization of the abandoned wind power and the environmental protection. On the basis of summarizing the research status of solid electric heat storage technology in China and other countries, the research progresses are analyzed in detail from the aspects of system-form, solid thermal storage materials, structure of thermal storage devices, the thermal storage/release performance, operation modes,control strategies and economic analysis. Then the applications oftypical solid electric heat storage devices are given. Finally, in combination with the development requirements of solid electric heat storage technology, the suggestions and prospects could provide references for the future researches and applications.
