摘要
在电力市场环境下 ,发电商的策略性投标行为关系到电价风险、市场稳定、市场力滥用行为及发电商自身利润等诸多问题。文中在对发电机组成本 /需求的微观经济分析基础上 ,建立了机组面对需求曲线的公式及求解方法 ,提出了机组市场价格控制区的新概念。基于经济学中企业经营决策的最大利润原理 ,阐述了“边际发电成本等于边际发电收入”的机组最优竞价准则 。
In the environment of electricity market, the strategic bidding behaviors of generator is relative to many problems, such as maximization of generation profits, risks of electricity price, stability of electricity market and abuse of market power. By analyzing the cost curve and demand curve of generators from the viewpoint of microeconomics, this paper presents the algorithm to acquire the firm demand curve of generator, and derives a new concept-Market Price Control Scope of generator. In light of profit maximization principle in business decision making, optimal bidding principle of generator is proposed which can be expressed as marginal generation cost equals to marginal generation revenue. Based on this principle, optimal bidding strategy and algorithm according to different generators with incoordinate market power are also presented respectively.
