能源互联网背景下的置信容量评估研究综述与展望

置信容量定义为等可靠性前提下可再生能源系统可以替代的常规机组的容量，置信容量是衡量供能系统对系统供能充裕性贡献的重要指标。随着我国能源互联网的发展，电—气综合能源系统的规模逐步扩大，考虑能源互联网背景下的置信容量将成为未来配电网规划中电力平衡的重要指标。综述了能源互联网背景下的置信容量的定义和主要计算方法，展望了未来有待进一步研究的方向。

Summary and prospect of research on confidence capacity evaluation in background of energy Internet

Confidence capacity is defined as the capacity of conventional units that can be replaced by a renewable energy system under the premise of equal reliability.Confidence capacity is an important indicator to measure the contribution of the energy supply system to the adequacy of system energy supply.With the development of my country′s energy Internet，the scale of the electricity-gas integrated energy system is gradually expanding.Considering the confidence capacity in the context of the energy Internet will become an important indicator of power balance in future distribution network planning.The definition and main calculation methods of confidence capacity in the context of the energy Internet were reviewed，and the future directions for further research were prospected.
