To realize reasonable decision-making of energy supply equipment's operation combination mode at different power and heat loads of the whole plant

an optimal decision-making method for multi operation combination mode of thermal power plant units equipped with electrode electric boilers is presented. Firstly

the simulation model of operation characteristics of each unit in thermal power plant under different operation modes is established

and the corresponding electrical and thermal output characteristics are obtained by simulation. Then

the energy supply cost and coal consumption are taken as the target functions to establish the multi-operation combination mode optimization decision model. After considering the auxiliary service market subsidy

the two gets the same unit flexible operation combination mode. Finally

the optimal operation combination mode of thermal power plants at different whole plant powers and thermal loads is obtained. Considering the minimum operation

the decision rules of multi operation combination mode of thermal power plant units are obtained according to the simulation results. The research results provide a basis for the operation combination mode decision-making of thermal power plant with electric boilers.
