摘　　要：温室气体排放权交易将给电力系统优化运行带来新的挑战。基于总量管制和排放交易(cap and trade)模式,提出计及排放权交易的机组组合(emission trading unit commitment,ETUC)模型。该模型不仅考虑了排放配额约束,而且考虑了排放权的交易。基于二阶锥多面体近似法,提出一种求解ETUC问题的新方法。该方法将ETUC问题转化为混合整数二阶锥规划(mixed integersecond-order cone programming,MISOCP)模型,然后利用多面体近似法将二阶锥约束转化为线性约束,形成解决ETUC问题的混合整数线性规划(mixed integer linear programming,MILP)模型。在10—100机组24时段系统上进行仿真计算,验证所提模型和方法的正确性和有效性。The greenhouse gas emission trading will bring new challenge to power system optimal operation. According to cap and trade mechanism, an emission trading unit commitment （ETUC）, in which both emission allowance and emission trading are considered, is proposed. Based on second-order cone polyhedral approximation a new method to solve ETUC problem is given. The proposed solving method turns the ETUC problem into mixed integer second-order cone programming （MISOCP）, then by use of polyhedral approximation the second-order conic constraint is transformed into linear constraint and the MISOCP model is turned into mixed integer linear programming （MILP） model, and then the ETUC problem can be solved. Through the simulation of power systems with the number of generation units from 10 up to 100 in a whole day divided into 24 time intervals, the correctness and effectiveness of the proposed model and method are validated.
