Starting from the review of past development of distributed energy resources (DER), this paper investigates the current situation and also future trend of DER development. The primary focuses of this paper include: 1) the potential and typical applications of DER in China; 2) the grid's hosting capacity for DER; 3) the methods for distributed generation (DG) to participate in electric power market. In this paper, we conclude that the DER is an essential and critical part of modern energy system. With our estimation, China has a potential capacity of 5 400 GW renewable DER for future development. By 2030, 2 000 GW of the DER capacity will be technically available and 500~800 GW of the DER capacity will be economically available, respectively for development.

Advanced adiabatic compressed air energy storage system （AA-CAES） is a kind of large scale electric energy storage and conversion technology which plays an important role in renewable energy grid and power peaking. In order to study the influence of the structure and operation mode of the thermal energy storage system on the performance of AA-CAES，the thermodynamic model of the thermal energy storage system is analyzed and a high temperature thermal energy storage system based on the traditional structure is proposed in this paper. The results show that when the stages of the compressor and expander are similar，the energy storage efficiency is the highest，and the greater the difference of the stages，the lower the energy storage efficiency.
