Abstract

The increasing penetration of renewables in power systems urgently entails the utilization of energy storage technologies. As the development of energy storage technologies depends highly on the profitability in electricity markets, to evaluate the economic potentials for various types of energy storage technologies under the comprehensive market environment is of great significance. To this end, this study aims at conducting a quantitative analysis on the economic potentials for typical energy storage technologies by establishing a joint clearing model for electric energy and ancillary service (AS) markets considering the operating features of energy storage systems (ESSs). Furthermore, a test system is adopted for numerical analysis that accurately represents for the real-world operation characteristics of power systems in China, with which the market prices, and operation schedules and profitability of ESSs are comparatively studied. The proposed methodology and results could provide beneficial references for the modifications on electricity markets and the development of ESSs towards the increasing penetration of renewables in power systems.

可再生能源电力市场中储能技术的经济潜力

可再生能源在电力系统中的日益普及，迫切需要利用储能技术。由于储能技术的发展高度依赖于电力市场的盈利能力，因此在综合市场环境下评估各类储能技术的经济潜力具有重要意义。为此，本研究旨在通过建立考虑储能系统运行特点的电能和辅助服务(AS)市场联合清算模型，对典型储能技术的经济潜力进行定量分析。采用测试系统进行数值分析，准确反映了中国电力系统的实际运行特点，对比研究了ess的市场价格、运行计划和盈利能力。所提出的方法和结果可以为电力市场的调整和ess的发展提供有益的参考，以适应可再生能源在电力系统中的日益普及。
