摘要(Abstract):
储能技术因其良好的可控性和能量的时间转移特性,在新型电力系统中具有重要应用价值。合理评判各场景下储能的价值并针对性选型具有重要现实意义。首先,针对电力系统的各类需求场景,提出了储能的10类技术经济性指标,构建了储能的综合评估指标体系。然后,利用层次分析法对上述指标进行了综合评估计算,计算过程中通过专家调查法对判断矩阵进行了相对重要性赋值,并进行一致性检验和修正,求出方案层相对于目标层的组合权重。接着,对多种类型储能进行综合评估计算,找到最优储能选型方案。最后,以某区域电网为对象进行仿真,得出了多种场景下各类储能的排序结果,验证了所提方法的有效性。
Owing to its high controllability and time transfer characteristics,energy storage technology is worth being applied in new-type power systems. The rational judgment of energy storage in various scenarios and the selection with a clear aim are of practical significance. First,10 types of technical and economic indicators of energy storage are proposed for various demand scenarios of power systems,and a comprehensive evaluation index system of energy storage is constructed. Then,comprehensive evaluation and calculation on the above indexes is carried out by using analytic hierarchy process(AHP),during which the relative importance of the judgment matrix is valuated by Delphi method,and the consistency check and correction are carried out to solve the combination weight of the scheme layer in relation to the target layer;then,a comprehensive evaluation and calculation of various types of energy storage is performed to obtain an optimal energy storage selection scheme. Finally,a regional power grid is simulated,and the ranking results of various types of energy storage under multiple scenarios are derived to verify the effectiveness of the proposed method.
