摘要: 电化学储能快速精准的调节特性非常适用于电网调频。为准确评价储能调节资源参与自动发电控制(AGC)的控制性能,基于Fréchet距离算法,通过计算时间周期内储能实际出力与理想出力曲线的相似度,提出了表征储能调节性能的相似度、延迟度、偏差度和贡献度指标。新型指标不仅能够准确表征储能的调节性能以及调节效果,同时也能适应常规机组的考核评价。基于储能和常规机组实际运行数据进行了算例计算,对比分析结果验证了提出指标的有效性。

Abstract: Due to its capabilities to provide fast and accurate regulation, the application of the electrochemical energy storage is suitable for frequency modulation in power grid. In order to accurately evaluate the control performance of energy storage resources when participating in AGC control, four control performance indices in terms of the similarity, delay, deviation and contribution indices are proposed by calculating the similarity between the actual output and ideal output curve of energy storage within certain time period. The new indices can not only accurately represent the energy storage regulating performance and effect, but also be adapted for the evaluation of conventional units. Case studies are performed using the actual operation data of both energy storage units and conventional units, such that the validity of the proposed indices are verified by comparison and analysis.
