Power system Flexibility quantitative evaluation A case study of Zhangjiakou
Proposing a quantitative evaluation method for power system flexibility analysis is crucial for renewable energy development, as flexibility is one of the fundamental factors to affect renewable power curtailment. Zhangjiakou is currently the only national renewable energy demonstration zone in China. However, as it faced severe curtailment issue during the 13th Five-Year Plan period, it is necessary to come up with technical and economic available solutions to improve local power system flexibility. The ERI of NDRC and NCEPU jointly develop a quantitative evaluation model – H3E – which could analyze this issue for Zhangjiakou. The results is published as a research paper on Energy.
