摘要
首先运用投资组合理论和线性规划的方法,建立了发电公司在完成计划交易电量下的利润模型,应用函数求导的单调性判别法,分析讨论期货电量和现货电量之间的不同比例对发电公司利润的影响,并对成本价格进行了相关的探讨。
Firstly, profit model of the generation company is constructed by investment combination theory and linear programming method when it correctly has completed the scheduling trading volume. This paper also analyses the profit effect with the different rates of futures trading volume and spot trading volume in the way of monotonicity discriminance by the function differential coefficient, and discusses the cost meaning. Depending on the analysis and results of the practical example, the profit function model which is constructed in this paper is applied and valid.
