考虑削减方法和最大化接纳能力的新能源准入容量柔性优化模型

为了最大化电网对新能源的接纳能力，研究了德国削减电量提高可再生能源准入容量的方法。首先阐述了削减电量运行方式的机理，介绍了静态、动态削减方法的区别。然后建立了优化新能源准入容量的模型，并且限制了弃风、弃光量。接着利用电力系统柔性方法，引入柔性指数和柔性区间处理间歇式可再生能源出力波动性的问题。最后进行算例分析，证明了削减电量方法能有效提高新能源准入容量，并探究了柔性指数的规律性。

Flexible Optimization Model for New Energy Access Capacity Considering the Method of Electricity Reduction and Maximum Acceptance

In order to maximize the grid's ability to accept new energy， the method of reducing electricity consumption in Germany is studied to increase the renewable energy access capacity. Firstly， the operation mode mechanism of reducing the electricity is described， the differences between static and dynamic reduction methods are introduced. Next， a model to optimize the new energy capacity is established， and the amount of abandoned wind and abandoned light is limited. Then， by using the flexible method of power system， the flexible index and flexible interval are introduced to deal with intermittent renewable energy output volatility. Finally， a case study is carried out to verify that the method can effectively increase new energy access capacity. The regularity of the flexibility index is explored.
