摘　　要：碳市场的引入改变了传统化石燃料机组的发电成本,从而影响其在电力市场中的竞价行为。同时,输配电网中涉及不同的市场主体,需在碳-电市场下研究输配电网的市场交易方法。提出了一种基于输配协同的碳-电耦合市场交易决策方法。首先,提出了考虑输配协同运行的碳-电耦合市场的交易框架。其次,构建了一种基于输配协同的多主体交易的碳-电耦合市场双层交易决策模型。上层模型为各个配电市场与发电商的碳-电协同交易决策模型,下层模型为输电市场和碳市场的出清模型,量化了碳配额与发电量间的关系。再次,通过Karush-Kuhn-Tucker(KKT)条件、对偶原理以及Big-M法将每个交易主体的双层模型转化为单层具有均衡约束的数学模型(mathematical problem with equilibrium constraints,MPEC),所有MPEC构成了均衡约束均衡规划(equilibrium problem with equilibrium constraints,EPEC)模型,并通过对角化算法进行求解。最后,基于T6-D7-D9和T30-D33系统进行算例分析。结果表明,所提方法可有效促进电力行业减少碳排放,降低运行总成本的同时提升社会福利。The introduction of the carbon market has changed the power generation cost of traditional fossil fuel units,thereby affecting bidding behavior in the electricity market.At the same time,different market players are involved in the transmission and distribution network,and it is necessary to study the market trading method of that network in the carbon-electricity market.This paper proposes a carbon-electricity coupling market trading decision-making method based on transmission and distribution coordination.First,a trading framework for the carbon-electricity coupling market considering the coordinated operation of transmission and distribution networks is proposed.Secondly,a two-layer trading model of the carbon-electricity coupling market based on multi-agent transaction based on transmission and distribution coordination is constructed.The upper models are the carbon-electricity collaborative trading decision-making models of each distribution market and power generators,and the lower models are the clearing models of the transmission and carbon markets.This quantifies the relationship between carbon quota and power generation.Then,the Karush-Kuhn-Tucker(KKT)condition,the duality principle and the Big-M method are used to transform the bi-level model of each trading agent into a single-layer mathematical model with equilibrium constraints(MPEC),and all MPECs constitute an equilibrium problem with equilibrium constraints(EPEC)model,which is analyzed by the diagonalization method.Finally,case analysis is carried out based on the T6-D7-D9 and T30-D33 systems.The results show that the proposed method can effectively promote the reduction of carbon emissions,reduce the total operating cost and improve social welfare in the power industry.
