摘　　要：随着电力市场改革的深化以及风电和太阳能为主的间歇性可再生能源发电(IREG)机组在电力系统中的占比不断升高,目前,对IREG机组采用的全额固定电价收购模式将按计划逐步终止,IREG机组将作为市场竞争主体参与电力市场,包括电力现货市场的运营。在此背景下,考虑绿色证书交易,通过建立三层决策模型优化政府对IREG机组的补贴政策,并引导其参与电力现货市场运营。首先,提出了过渡机制并建立了多市场多主体交易框架。然后,分别以求解最优合约覆盖率、社会效益最大化的市场出清和发电机组参与现货市场的最优投标策略为目标,建立了考虑绿色证书交易的多主体三层优化决策模型,并以市场出清结果作为这三层模型间的交互数据。接着,基于KKT(Karush-Kuhn-Tucker)条件,将该三层优化决策模型转化为混合整数线性规划模型,以提升求解效率。最后,通过算例对所提过渡机制的可行性和有效性进行了验证。With the deepening of electricity market reform and the ever-increasing penetration of intermittent renewable energy generation(IREG)units dominated by wind power and solar power generation in the power system,the current full-quantity fixedprice procurement scheme for IREG units will be gradually stepped down as planned,and the IREG units will participate in the electricity market as market competition entities,including the electricity spot market operation.In this context,considering the green certificate trading,a three-layer decision-making model is established to optimize the government subsidy policy for IREG units and guide them to participate in electricity spot market operation.First,the transition mechanism is proposed,and the involved multi-market multi-entity transaction framework is established.Next,a multi-agent three-layer decision-making model considering green certificate trading is formulated aiming at optimizing the contract coverage ratio,maximizing social welfare in market clearing,and optimizing the bidding strategies of generation units in the electricity spot market,respectively.And the market clearing results are used as the interactive data among the three layers.Then,based on the Karush-Kuhn-Tucker(KKT)condition,the three-layer decision-making model is transformed into a mixed-integer linear programming model,so as to improve the solution efficiency.Finally,the feasibility and effectiveness of the proposed transition mechanism are demonstrated through a case.
