北京电网分布式电源可接纳容量分析

Research and Analysis on the Grid Connection Operation of Multi-DG in Beijing Power Grid

在分布式发电研究当中关于分布式电源的准入容量的研究是最重要的研究方向之一。研究中根据北京电网的实际情况,综合考虑电网的静态约束、暂态约束及电力平衡约束,采用试探法分别对风力发电、光伏发电和冷热电三联供三种形式的分布式电源的独立准入容量进行了仿真计算分析,找出了限制不同形式的分布式电源接入容量的主要因素;结合分布式电源资源约束以及国外运行成熟的多元分布式电源典型配比,对多元分布式电源的综合准入容量进行了仿真计算分析;研究结果可供确定三类典型分布式电源的未来可能发展规模参考。

The maximum penetration level of distributed generation （DG） of a power system is one of the most impor- tant research directions in the DG research field. In this study,according to the actual situation of the Beijing power grid, considering the constraints of static security, transient security and power balance, heuristic was used for wind power,solar photovohaic power and combined cooling heating and power （CCHP） to identify the bearable DG capac- ity respectively and found out the main constraints to bearable capacity of three different form of DG. Considering the resources constraints to DG and foreign distributed generation＇ s typical running ratio,this paper analyzes the compre- hensive bearable distributed generation capacity （DG） of Beijing power grid. The results can be used to determine the future development scale of three typical distributed generations.
