电力市场中竞标电价及其影响因素

从微观经济学的角度研究了发电公司竞标电价及其影响因素。影响发电公司竞标电价的主要因素有发电公司本身的生产成本、市场需求量、价格-需求弹性、市场供给能力和限价机制等。首先研究了发电公司的生产成本和边际成本。边际成本曲线构成了发电公司的供给曲线,由此确定竞标电价的最低点。在具有较大的价格弹性的电力市场中,市场需求和价格弹性对发电公司竞标电价及其优化也有很大的影响。发电公司可以在低的市场价格时大幅度增加机组竞标量,在高的市场价格时适当减少机组的竞标电量,从而形成最优的竞标策略。限价机制约束了发电公司竞标电价上下限界,使得利益在发电公司和用户之间来回移动。

Bidding Prices And Its Influence Factors in Electricity Markets

Bidding price of generators are discussed with microeconomics in this paper,and some main influencing factors such as production costs,market demand,price elasticity,market provision and limited prices are also studied in this paper.The curve for generators makes up of their marginal costs curves,at the lowest point of which the bidding price is determined.In a competitive market with a greater price elasticity,the bidding price of generators are influenced by market demand and price elasticity in a greater degree.Generators may increase their bidding quantities in lower market price hours,and decrease their bidding quantities in higher market price hours so as to make optimal bidding strategies.The police of limited prices influences the bidding prices of generators,with a result of benefit relocating between generators and users.
