基于风险效益均衡的电煤差价合约研究

在由煤炭供应价格所引发的煤炭供应企业和发电企业之间的矛盾仍未解决的情况下,引入电煤差价合约,采用概率分析法对发电企业和煤炭供应企业的风险进行衡量,并通过建立风险效益平衡模型来确定最优订货比例。通过算例分析,证明了所提出的模型具有一定的可操作性,有利于建立公平的市场模式,可有效解决由煤炭供应价格所引发的煤炭供应企业和发电企业间的矛盾。

Study on Contract for Difference between Coal Producer and Electricity Generator under Equilibrium of Risk and Benefit

Owing to more and more server price confrontations between coal producers and generation enterprises in China, this paper introduces the Contract for Difference ( CFD) . Firstly, it evaluates the risks of coal producers and generation enterprises by the probability analysis method. Secondly,it establishes a marginal risk-benefit balance model for two parts to determine the optimal coal-ordering proportion. Finally,it verifies that the proposed model in this paper is suitable, and helps to construct fair market mode and solve the price contradiction between coal producers and generation enterprises.
