摘要：

在清洁能源大规模接入和电网调峰压力日益加剧的背景下,储能装置和深度调峰火电机组作为促进新能源消纳和平抑电网峰谷差的重要调节资源,已受到学术界和工业界的广泛关注。文章综合考虑了多类型储能装置的自身特点,并结合了火电机组的深度调峰特性,对不同类型储能装置参与调峰的经济效益进行了深入分析。首先,选取并建立了最具代表性的3种能量型储能系统(抽水蓄能、压缩空气储能和锂离子电池储能)的运行模型;其次,考虑火电机组的深度调峰特性,建立了火电机组的运行模型和经济性模型;再次,考虑多类型储能系统的全寿命周期成本,构建了考虑火电机组深度调峰的多类型储能系统日前经济调度模型,并据此开展了多类型储能经济性对比分析;最后,基于某地区的典型日数据开展了算例仿真,对比分析了各类型储能电站的经济效益并给出了储能容量配置建议。

Abstract:

In the context of the large-scale access of clean energy and the increasing pressure of peak-shaving power grids, energy storage devices and deep peak-shaving thermal power units, as important adjustment resources to promote the absorption of new energy and suppress the peak-valley difference of the power grid, have been widely concerned by academia and industry. Considering the characteristics of multi-type energy storage devices and combined with the deep peak-shaving characteristics of thermal power units, this paper compares and analyzes the economic benefits of different types of energy storage devices assisting deep peak-shaving of thermal power units. Firstly, by fully considering the technical, economic characteristics and development prospects of multi-type energy storages, the most representative three kinds of energy storage systems: pumped storage, compressed-air energy storage and lithium-ion battery energy storage are selected, and the relevant system operation models are established. Secondly, considering the deep peak-shaving characteristics of thermal power units, the operation model and economic model of thermal power units are established. Thirdly, considering the life-cycle cost of multiple-type energy storage systems, a day-ahead economic dispatch model of multi-type energy storage systems considering the deep peak-shaving of thermal power units is constructed, and a comparative analysis of the economics of multi-type energy storage is carried out accordingly. Finally, on the basis of the typical daily data in a certain area, a simulation example is carried out to compare and analyze the economic benefits of multi-type energy storage power stations, and the recommendations of energy storage capacity configuration are put forward.

Key words: multi-type energy storage, thermal power unit, deep peak regulation, life cycle, economic analysis
