“双碳”目标下能量互补系统对燃煤机组的优化提升

Optimisation of Coal-Fired Units with Complementary Energy Systems under the"Dual Carbon"Target

为了优化传统燃煤机组大惯性的问题,以及减少碳排放量,从而实现燃煤机组效率的提升。研究采用串并联方式构建了一种太阳能-燃煤能量互补机组,并采用参数辨识的方法实现机组调控。结果显示,不论是受到阶跃干扰还是斜坡干扰,研究所提能量互补系统均优于传统发电系统,其调节速度更快、波动更小、安全性更高。

In order to optimise the problem of large inertia of traditional coal-fired units and reduce carbon emissions,the efficiency of coal-fired units is improved.A solar-coal-fired energy complementary unit is constructed by series-parallel connection,and a parameter identification method is adopted to achieve unit regulation.The results show that the energy complementary system proposed in the study outperforms the conventional power generation system in terms of faster regulation,smaller fluctuation and higher safety,regardless of whether it is subjected to step or ramp disturbances.
