【 摘 要 】

Renewable energy curtailment is increasingly a critical issue in China. Mechanism barriers are becoming a key constraint for renewable energy integration, in which downward regulation mechanism that incentivizes conventional generators to be dispatched down is playing a key role in some regions, such as Northeast China. Pilots of such market mechanism, i.e. downward regulation ancillary service mechanism, have already been initiated in Northeast China. This paper evaluates the impact of downward regulation ancillary service mechanism in power systems with high penetrations of renewable energy. Firstly, the current situation of renewable energy development in China is analyzed. Secondly, the current practice of downward regulation ancillary service market mechanism in China are summarized and analyzed. Thirdly, the evaluation methodology as well as the case study system are described. Fourthly, simulation results are presented and analyzed. Finally, implications and suggestions are proposed.
