【摘要】：十八大之后,电改方案出台的脚步已经愈发临近,在能源领域特别是电力产业,以社会主义市场经济为主导的模式将逐步取代电力垄断经济体系,电力市场化的脚步已经不可逆转。“竞价上网”作为发电侧电力市场的主要形式必将一步步实行和完善。火力发电企业为了适应改革发展的需要,在挖潜增效、降低成本的同时,必须建立一套实用的竞价投标策略来达到企业利益的最大化,为其在电力市场中的竞争提供依据。本文首先介绍了电力市场的定义、特征、类型和交易模式,分析了国内和国际电力市场的运行机制和交易过程。从研究火电厂发电成本的组成,推算出发电边际成本与固定成本无关,将发电边际成本简化为由燃料成本进行考虑。对燃料成本的控制提出了基于发电成本最低的数学模型,并利用移动平均数法与季节变动系数结合来预测了机组供电煤耗数据,从而得到机组的边际发电成本。最后给出基于边际发电成本的竞价策略,为火电厂机组参与电力市场竞争提供报价参考。
[Abstract]:After the 18 National Congress, the pace of the electricity reform plan has been getting closer and closer. In the field of energy, especially in the power industry, the socialist market economy will gradually replace the power monopoly economic system. The pace of electricity marketization has become irreversible. As the main form of power market on the power generation side, "bidding for the Internet" will surely be implemented and perfected step by step. In order to meet the needs of reform and development, thermal power generation enterprises are tapping potential and increasing efficiency and reducing costs at the same time. It is necessary to establish a set of practical bidding strategies to maximize the interests of enterprises and provide the basis for their competition in the electricity market. This paper first introduces the definition, characteristics, types and trading models of power market, analyzes the operation mechanism and transaction process of domestic and international electricity markets. It is concluded that the marginal cost of power generation is independent of the fixed cost, and the marginal cost of power generation is simplified to be considered by the fuel cost. A mathematical model based on the lowest generation cost is proposed for the control of the fuel cost. Using the moving average method and the seasonal variation coefficient to predict the coal consumption data of the unit, the marginal generation cost of the unit is obtained. Finally, the bidding strategy based on the marginal generation cost is given. For thermal power plant units to participate in the electricity market competition to provide quotation reference.
