摘　　要：电力中长期合约是市场经营主体用于规避市场交易风险、锁定价格的重要工具。对于发电侧经营主体,按照机组出力特点签订电力中长期合约曲线,能够缩小执行偏差、降低差额费用。本文以某地电力市场建设为基础,首先,分析中长期合约曲线的分解、安排和出清需求;其次,以可再生能源与火电及系统运行为约束,考虑合约均衡、可再生能源优先等因素,构建计及均衡执行的电力中长期合约曲线分解模型;最后,以实际算例验证提出的中长期合约电量分解模型的可行性。研究发现,本文所提出的研究方法能够确保竞价机组合约执行的公平性,为现货交易启动初期的电力系统运行及市场发展提供决策支持。基于此,中长期合约曲线应尽量分解至电力层面的细分时段,中长期合约签订应逐步引导市场经营主体自行分解曲线,中长期合约与现货交易衔接应确保系统运行综合效益最大化。The mid-and-long term contract of electric power is an important tool for market players to avoid market transaction risks and lock prices.For power generator units,signing the mid-and-long term contract curve of electric power according to the output char-acteristics will narrow the execution deviation and reduce cost.Based on the construction of electricity market in a province,this paper first-ly analyzes the decomposition,arrangement and clearing demand of mid-and-long term contract curve.Secondly,taking renewable energy,thermal power,and system operation as constraints,considering contract balance,renewable energy priority and other factors,this paper con-structs the decomposition model of mid-and-long term contract curve with equilibrium execution.Finally,an example is given to verify the feasibility of the proposed model.It is found that the research method proposed in this paper can ensure the fairness of the execution of bidding unit contracts,and provide decision support for power system operation and market development in the initial stage of spot trading.Based on this,the mid-and-long term contracts should be decomposed into time-sharing electric power curves,the signing of mid-andlong term contract should gradually guide market players to decompose the curve by themselves,and the connection between mid-and-long term transaction and spot transaction should ensure that the comprehensive benefits of system operation are maximized.
