考虑灵活性分析的典型光伏日出力率曲线提取方法
Method for Extracting Typical PV Daily Output Curves Considering Flexibility Analysis
摘要
Abstract
In the process of analyzing the flexibility of the power system,it is necessary to extract typical photovoltaic(PV)daily output curves that have a significant impact on the system flexibility.This paper proposes a method for extracting typical PV daily output curves considering flexibility analysis.The method determines the range of PV daily generation curves that have a significant impact on flexibility,improves the K-means clustering algorithm using Spearman correlation coefficient and random greedy algorithm,clusters the PV daily output rate curves,and extracts typical PV daily output rate curves using the grey wolf algorithm.A case study is conducted using the PV output data from the Inner Mongolia west power grid from 2019 to 2022.The results show that the typical PV daily output rate curves extracted using the proposed method can effectively reflect the impact of PV power generation on system flexibility.关键词
