Economic analysis and optimization of energy storage systems participating in frequency regulation services in electricity markets
储能系统参与电力市场调频服务的经济性分析与优化

摘要

随着可再生能源比例的提升，电力系统面临频繁的供需波动，传统调频方式已难以满足电力市场的需求。储能系统作为一种灵活、高效的能源调节手段，在参与电力市场调频服务中展现出巨大的潜力。本文通过分析储能系统在调频服务中的经济性，探讨其优化参与策略，并提出了通过经济调度模型和市场机制优化储能参与调频服务的方案。储能系统能够有效降低调频成本，并提高电力系统的运行稳定性。优化储能调度策略对于提高系统经济效益具有重要意义。

Abstract

With the increase in the proportion of renewable energy, the power system is facing frequent supply-demand fluctuations, and traditional frequency regulation methods have struggled to meet the needs of the electricity market. As a flexible and efficient energy regulation means, energy storage systems (ESS) have demonstrated great potential in participating in frequency regulation services of the electricity market. This paper analyzes the economy of ESS in frequency regulation services, discusses optimized participation strategies, and proposes a scheme to optimize ESS participation in frequency regulation services through economic dispatch models and market mechanism improvements. The study shows that ESS can effectively reduce frequency regulation costs and enhance the operational stability of the power system. Optimizing ESS dispatch strategies is of great significance for improving the economic benefits of the power system.
