Abstract: With the continuous expansion of grid-connected scale of new energy power generation the pressure of power grid peak load regulation increases increasingly, so it is difficult to meet the need of rapid development of new energy, and it becomes a burning question how to complete and deepen the mechanism of ancillary peak regulation service market and then to improve the regulation ability of power grid. On this background, firstly, the development history and key policies of China’s auxiliary power service market were sorted. Secondly, five typical regions were chosen to carry out the inductive classification and comparative analysis on the policy and the mechanism of their auxiliary peak-load regulation service market. Finally, combining with the developmental background of China’s auxiliary peak-load regulation service market and the actual developmental situation of the peak-load regulation service market in each region, under the goal orientation of constructing new type power system four suggestions are put forward to provide research direction for the construction of China’s auxiliary peak-load regulation service market in the new period and to give a new thought for the accommodation of high proportion of renewable energy.
