相变储能技术在电力调峰中的工程应用

Applications of latent heat energy storage technology in peak load regulation of power system

介绍几种相变储能技术在电力调峰中的应用,进行相变蓄能电采暖装置应用的技术经济分析。认为电热相变蓄热装置体积小,寿命周期成本低,投资回收年限短,应为蓄热式电采暖的首选形式。实行谷期电价是峰期电价的1/4,对电力供求方都是有利的。

Several ways of latent heat energy storage applied in peak load regulation of power system are introduced and the technical economical analyses of electrothermic latent heat energy storage equipment used in space heating are conducted in this paper. The analyses show that as a result of the advantages,such as smaller size,lower life period cost and shorter payback period,the latent heat energy storage system should be the first choice of electrothermic energy storage. It is beneficial to both demand side and supply side in the power system. when electricity tariff of off peak hour is one fourth of that of peak hour.
