摘要
储能系统的大力推广既有赖于储能技术的更迭发展,也与相关政策的合理制定密切相关。近年来,国内外政府为提高电力系统辅助服务质量,制定了一系列规定来根据调频辅助服务效果对发电行业进行奖惩,也激励着储能系统应用到发电侧来提升辅助服务质量。对辅助燃煤机组调频的储能系统进行全生命周期过程中的经济性分析,在《两个细则》的基础上,研究国内各项二次调频考核性能指标和储能系统对于调频性能的提升能力。同时为避免储能系统过充过放情况对储能系统的荷电状态(SOC)有所限制,并采取SOC越线回归策略。最后根据储能系统在全生命周期过程中的各项成本和收益进行核算,建立经济收益最大化的目标函数,并使用遗传算法来优化出适合燃煤机组的最优容量和最佳功率。
The vigorous promotion of energy storage systems not only depends on the development of energy storage technology, but also closely relates to the rational formulation of relevant policies. In recent years, in order to improve the quality of auxiliary services of the power system, governments at home and abroad have formulated a series of regulations to reward and penalize the power generation industry based on the effect of frequency modulation auxiliary services, and also encourage the application of energy storage systems to the power generation side to improve the quality of auxiliary services. This chapter mainly analyzes the economics of the energy storage system of auxiliary coal-fired unit frequency modulation during the whole life cycle. Based on the new version of the "Two Detailed Rules", it studies the performance indicators of domestic secondary frequency modulation assessment and the impact of energy storage systems. Improved FM performance. At the same time, in order to avoid the overcharge and overdischarge of the energy storage system, the state of charge(SOC) of the energy storage system is limited, and the SOC cross-line regression strategy is adopted. Finally, calculate the cost and benefits of the energy storage system during the entire life cycle, establish an objective function for maximizing economic benefits, and use genetic algorithms to optimize the optimal capacity and power for coal-fired units.
