The development of high proportion of new energy has promoted the scale application of energy storage in power system, and many provinces in China have built a peaking auxiliary service market to adapt to the participation of energy storage. The offer strategy of energy storage in the peaking market will affect its revenue in the power market. The clearing and price mechanism is analyzed of energy storage in the domestic typical peaking market. Based on the peaking auxiliary services in Guangxi with graded clearing，four quotation strategies of energy storage in the peaking market are designed. An example to compare and analyze the market revenue is constructed of energy storage under the four quotation strategies, and come up with a proposed scheme for energy storage quotation in the peaking market.
