Demonstration Projects of Integrated Energy System in China

Being the main direction of energy system development, the integrated energy system consisting of power supply, heating supply, gas supply, and so on fully exploits the potentials of different energy systems. In this paper, the domestic status of its pilot projects is summarized and their practical experiences are analyzed. The successful cases of projects show that, the policy support is the basis of its development and the multi-energy coordinated control is the key technology of multi-energy complementation for the efficient utilization of energy and the large-scale accommodation of renewable energy. Finally, suggestions about the domestic development of integrated energy system are given.
