低碳经济下基于合作博弈的风电容量规划方法

Cooperative Game Based Capacity Planning Model for Wind Power in Low-carbon Economy

在低碳经济下,通过引入碳交易过程,将风电的减排效益量化为实际的经济价值。基于合作博弈理论,分析了风电规划运行中风电场与电网的改进策略以及双方的成本效益变动,提出了风电—电网联盟净收益最大的风电场容量规划模型,并构建了风电场与电网间公平、合理的利润分配机制,最后,通过具体算例分析了模型的实用性。分析结果表明,风电—电网的合作模式既有利于提高电网消纳风电的积极性,又有利于避免风电场的无序扩张,可为目前风电规划中出现的场网不协调问题提供改进方案。

In the low-carbon economy,a carbon trading process is introduced in order to quantify the effect by actual economic value.In this process,a cooperative game based planning model for wind power is proposed while the improvement strategies and cost/benefit for both wind farms and the grid company are analyzed.Furthermore,a reasonable profit distribution model of the alliance of wind farms and grid companies is built to achieve the fairness of profit distribution.Example analysis indicates that the alliance of wind farms and grid companies is effective in incentivizing the grid companies,avoiding disorderly expansion of wind power,and also providing solutions for the mismatch issue between the wind power and available connection points.
