摘要

针对当前储能综合评价体系中优化调度目标与评价指标脱节导致的评估结果片面性问题,以新型电力系统关键灵活性资源——压缩空气储能为研究对象,提出一种基于多维指标-多时间尺度耦合协同优化调度的压缩空气储能电站并网效益综合量化评价方法。首先,构建包含经济性、低碳性及稳定性的多维评价指标体系;其次,将经济性、低碳性及稳定性分别作为日前、日内及实时调度的目标,建立多维指标-多时间尺度耦合的协同优化调度模型;进一步,基于场景对比法建立压缩空气储能各评价指标的定量分析模型,并采用层次分析法、熵权法及逼近理想解排序法构建其综合评价模型。最后,对不同运行场景下压缩空气储能电站并网运行效益进行综合评价研究,结果表明,相较于传统基于日前考虑经济性单目标优化调度的综合评价方法,该文所提的评价方法能获得更高的综合评价分数,且有效改善了传统评价方法中存在的经济性效益维度得分占比过高的问题,实现了多维评价指标的全面均衡考量。

Abstract

In response to the issue of one-sided assessment results caused by the disconnection between optimization scheduling objectives and evaluation indicators in the current comprehensive evaluation system for energy storage, this study focuses on compressed air energy storage （CAES）, a key flexible resource in the new power system. It proposes a comprehensive quantitative evaluation method for the grid-connected benefits of CAES based on multi-dimensional indicators and multi-time scale coupled collaborative optimization scheduling. First, a multi-dimensional evaluation indicator system is constructed, which includes economic, low-carbon, and stability indicators. Next, these indicators are separately set as objectives for day-ahead, intraday, and real-time scheduling, establishing a collaborative optimization scheduling model that couples multi-dimensional indicators with multi-time scales. Furthermore, a quantitative analysis model for each evaluation indicator of CAES is developed based on scenario comparison methods, and a comprehensive evaluation model is constructed using the Analytic Hierarchy Process, entropy weight method, and Technique for Order Preference by Similarity to Ideal Solution. Finally, a comprehensive evaluation study is conducted on the grid-connected operational benefits of CAES under different operating scenarios. The results indicate that, compared to traditional comprehensive evaluation methods that focus solely on economic optimization scheduling based on day-ahead considerations, the proposed evaluation method achieves a higher comprehensive evaluation score and effectively addresses the issue of excessively high scores in the economic benefit dimension found in traditional evaluation methods, achieving a balanced consideration of multi-dimensional evaluation indicators.
