| 摘 要： | 打破电力市场垄断，提高农村电力市场效率，以及抑制市场力滥用是当今农村电力市场改革的主要方向之一。本文基于非合作博弈理论，提出了一种含买卖双边金融期权的、按照古诺竞争模式在现货市场和期权市场进行2阶段博弈的模型。由多家独立发电商与惟一的电网公司首先在期权市场中签订双边合同，决策出各自售出的最优期权数量；之后在现货市场进行产量竞争，在各自拥有期权头寸已知的情况下，选择其发电出力使自身期望收益最大。利用反向推倒方法求解模型，分析了模型中不同参数的变化对市场均衡结果的影响。通过理论研究和算例分析证明，与现有模型相比较，本文提出的含双边金融期权模型能够更大程度上降低市场出清价格以及提高发电量，可为电力监管机构与市场决策者引导参与者有序竞争提供一种新思路。

Research on Rural Power Market Cournot Equilibrium Model with Bilateral Financial Options |
| |
| Abstract: | To break monopoly, improve rural market efficiency and curb market power abuse are the fundamental direction of electricity reform. Based on non-cooperative game theory, a Cournot model with bilateral financial options is developed. Some IPPs and a grid company are in the game of two-period in options and spot markets. They sign a bilateral options contract in the options market in the first instance and make a decision to sell the optional options quantity; and then the IPPs compete in spot market, make a decision to choice they power output to their maximum expected benefit in the event that the options which they hold and sell have been known. The model can be solved by backward induction method, and the influences of different parameters in the model to the market equilibrium are analyzed. By comparing with existing models, the results show that the model with bilateral financial options has stronger effect on power market and it can improve social welfare greatly from the theoretical studies and numerical simulation analysis. It provides a new idea to guide the competition orderly and effectively for regulators. |
