Carbon Emission-Considered Multi-Objective Dynamic Optimal Power Flow of Power System Containing Carbon-Capture Plant

为满足节能减排的要求,在碳捕集电厂的背景下,建立兼顾CO2排放和有功网损的多目标动态最优潮流模型。用模糊集理论将多目标优化问题转化为求取满意度最大的单目标问题,用内点法进行求解。对IEEE-30节点6机系统进行算例仿真,结果表明所提出的多目标动态最优潮流模型,可以在兼顾网损的同时减少CO2的排放,验证了模型的有效性。

To meet the demand of energy-saving and emission reduction, under the background of power system containing carbon-capture plant a multiobjective dynamic optimal power flow model, in which both CO2 emission and active network loss are considered, is built. Based on fussy set theory, the multiobjective optimization problem is turned into the single objective problem, by which the maximum satisfaction degree is attained, and solved by interior point method. To verify the effectiveness of the proposed model, simulation of IEEE 30-bus 6-machine system is performed, and simulation results show that using the proposed multi-objective dynamic optimal power flow model the CO2 emission can be reduced while the active network loss is taken into account.
