中文摘要:
      在光伏发电蓬勃发展的背景下,光伏电站参与电网无功/电压控制的需求也日趋强烈,有效评估光伏电站的无功控制能力具有重要的理论和现实意义。然而,光伏电站无功控制能力评估研究仍在起步阶段且难度较大,需从评估指标体系构建、指标权重赋值、综合关联评估多个方面进行深入探索。鉴于此,提出了一种基于动态时间弯曲关联分析的光伏电站无功控制能力评估方法,解决综合评估指标体系建立及层次分析赋值问题的同时,将无功控制能力指标评估问题转化为空间上的模式距离关联匹配问题,采用动态时间弯曲法实现不同序列间的关联分析,计算标准、参考及待评估指标序列的关联匹配系数,进而确定无功控制能力等级,实现综合分级评估。并开展典型系统评估应用,验证所提评估方法的适应性及有效性。
英文摘要:
      With the development of photovoltaic power generation, and with the increasing need of photovoltaic power stations (PVPS) to participate in power grid reactive power and voltage regulation, the evaluation of reactive power control ability of PVPS, which has attracts additionally attentions for its great significance. However, current research on the evaluation of reactive power control ability is still in its infancy and faces more difficulties, further investigations are needed to carry on several aspects, including evaluation indexes construction, index weight determine and relation analysis-based comprehensive evaluation. In this study, a novel dynamic time warping (DTW) relation analysis-based reactive control ability evaluation method for PVPS, it establishes comprehensive evaluation index system and solves the corresponding weight assignment problem based on analytic hierarchy process (AHP), it also transforms the reactive power control indicators evaluation problem into distance correlation matching problem. The proposed DTW algorithm is applied to achieve relation analysis and calculate the correlation matching coefficients among the standard, reference and evaluation index sequences, then the reactive power control level can be determined and the comprehensive classification evaluation can be executed. Simulation results of typical PVPS are illustrated to demonstrate the effectiveness of the proposed DTW-based method.
