基于边际成本分析的燃煤电厂电力现货市场竞价策略

Bidding Strategy for Electric Power Spot Market of Coal-fired Power Plants Based on Marginal Cost Analysis

随着电力市场改革的不断深化,广东电力现货市场进入了试运行阶段。从燃煤电厂的角度出发,研究了广东电力现货市场在电力现货市场环境下的发电成本及竞价策略。首先介绍电力现货市场的基本情况与主要机制,在分析燃煤电厂发电成本各项构成的基础上,用机组经济性曲线拟合的数学计算方法得出机组在不同负荷下的发电成本;结合电力现货市场的特点,分析燃煤电厂的竞价策略,为燃煤机组参与竞价上网提供成本经济分析和报价参考。

With continuous deepening of electric power market reform, Guangdong electricity spot market has entered into the commissioning stage. From the point of coal-fired power plants, the paper studies power generation cost and bidding strategy of Guangdong electricity spot market in the environment of electric power spot market. It firstly introduces basic situations and the main mechanism of the electric power spot market, and on the basis of analyzing each component of power generation cost of the coal-fired power plant, it uses the mathematical computation method of economic curve fitting of the power generation unit to obtain power generation cost of the unit under different loads. Combining characteristics of the electric power spot market, it analyzes the bidding strategy for the coal-fired power plant, which could provide economic analysis for cost and bidding reference for the coal-fired unit participating in electric power bidding.
