Abstract: The integration of electric boiler and thermal storage system into power system is a feasible scheme

to improve system flexibility and wind power consumption. In order to comprehensively consider the multi-agent

configuration of electric boilers and heat storage systems in different thermal power plants，and also consider the

clearing price in peak shaving market，an optimal configuration model of electric boilers and heat storage systems

in multiple thermal power plants based on Cournot model was proposed. From the perspective of the main body of

the thermal power plant，the upper optimization model based on Cournot model was constructed to maximize the

annual peak shaving net income of the thermal power plant；secondly，the optimal adjustment model of the electric boiler and heat storage system was established to minimize the total fuel consumption and the abandoned air under the combined scenario. Finally，the rationality and effectiveness of the proposed model were verified by simulation examples of 9-bus system.
