采用线性供应函数均衡方法 ,针对多个具有非零截距线性边际成本的非对称发电商 ,研究了考虑远期合同交易的发电市场均衡模型。提出了 2种方法 ,即基于发电阈值电价的方法与基于竞标阈值电价的方法 ,来获取分段均衡的供应函数 ,并计及发电商出力限制对均衡结果的影响。算例分析表明了模型的有效性 ,并且显示 ,如果市场规则要求发电商投标时必须保证其合同电力 ,则在发电商的合同销售电力较大时 ,这种市场规则通常将导致市场均衡价格的明显下降。 By using the linear supply function equalization method, the equilibrium model of generation market considering forward contract transaction is studied for many asymmetric generators with linear marginal cost of non-zero intercept. Two methods are proposed, that is, the method based on the power generation threshold and the method based on the bidding threshold are used to obtain the supply function of the subsection equilibrium and the influence of the power suppliers’ output constraints on the equilibrium results. The case study shows the validity of the model and shows that if the market rules require the power suppliers to guarantee the contracted power when bidding, the market rules will usually lead to the equilibrium price of the market Significant decline.
