一种基于调峰平衡的风光综合消纳分析方法

An Integrated Analysis Method for Wind & Solar Power Accommodation Based on Peak Regulation Balance Principle

风光协同发展成为中国新能源发展当前及未来需要重点关注的内容之一。以系统调峰平衡分析为基础,结合风电和光电出力特性统计特征,提出了一种风光综合消纳分析方法。该方法通过典型日负荷晚高峰时段系统电力平衡确定风电装机,再通过负荷午高峰时段系统电力平衡确定太阳能发电装机,有效地解决了传统调峰平衡方法通过调峰盈余来确定风光装机组合时面临的不确定性问题。最后仿真算例验证了所提方法的有效性。

The coordinated development of wind and solar power has become the focus of China's renewable energy development in the current and future. Based on the principle of system peaking regulation balance, and with combination of the statistical characteristics of wind power and solar power output characteristics, an integrated analysis method is proposed for accommodation of wind and solar power. By firstly determining the installed capacity of wind power through system power balance for the night peak load period in a typical day, and then figuring out the installed capacity of solar power through system power balance for the midday peak load hours, the proposed method effectively solves the problem of uncertainty for the conventional peak regulation balance method, which determines the combined installed capacity of the wind and solar power through peak regulation surplus. The simulation results have validated the effectiveness of the proposed method.
