| 摘要: |
| 在将电力市场中的发电公司分为价格领导者、跟随者和接受者的前提下, 考虑双边合同并引入绿色证书交易机制，建立了大用户直购电市场寡头垄断模型并进行了均衡分析。用有5家发电公司参与的电力市场为例，分析了合约电量、绿色证书价格、绿色能源波动等关键因素对市场均衡的影响。分析结果表明：随着合约电量的增大，发电公司在电力市场上总的发电出力增加，而市场电价和发电公司的总利润下降；应保持证书价格稳定，防止市场波动过大，有效促进可再生能源发电的发展。 |

| Abstract: |
| A math model of oligopolistic market with direct electricity purchase is established and analyzed，which classifies the electricity producers as the price-leader，price-follower and price - recipient，considers the bilateral contracts and introduces the green certificate system to it. With an electric power market including five power generation corporations as an example，the influence of the bilateral contract amount，green certificate price and green power fluctuation on the market equilibrium is analyzed. The conclusions of analysis are：along with the increase of bilateral contract amount，the total power generation of power generation corporations increases while their total profit，as well as the electricity price，reduces；the green certificate price should be kept stable to avoid the serious fluctuation of electricity market and promote the development of renewable energy. |
