With the abrupt growth of installed capacity of wind and thermal power units in the northeast

northwest and North China

difficulties in power system operation and peak regulation are becoming increasingly outstanding. In 2014

the peak regulation ancillary service market in China was launched and run in the Northeast Grid. This market has made great effort to bring the initiative of thermal power enterprises into full play using the economic leverage and market means to further explore the potential of their peak regulation capabilities. And improvement of the accommodation of clean energy

while mitigating operation pressure and ensuring safe and stable operation of the power grid. The performance of the market shows that it has done an active exploration and played an exemplary role in enhancing the peak regulation of the power grid and improving the accommodation of the renewable energy. To further perfect the rules of the Northeast Grid peak regulation ancillary service market

this paper mainly focuses on the following topics: the historical background

design objectives

basic principles of this market

the specific rules

practical results and the operation problems

etc.
