Multioperation combination mode optimal decision-making of thermal power plant with electric boiler under auxiliary service market

为实现不同的全厂电、热负荷下供能设备运行组合模式的合理决策,提出一种含电锅炉的热电厂多运行组合模式优化决策方法。首先根据含电锅炉热电厂不同运行模式下的电热特性,建立热电厂各机组运行特性的仿真模型,得到相应的电、热出力特性。然后分别以供能成本和供能煤耗为目标函数,建立多运行组合模式优化决策模型,在考虑辅助服务市场补贴后,两者得到的机组灵活运行组合模式一致。最后,得到不同全厂电、热负荷下热电厂最优运行组合模式,在考虑尽量减少运行操作情况下,根据仿真结果给出热电厂多运行组合模式的决策规则,这一结果可为含电锅炉热电厂运行组合模式决策提供依据。

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.
