摘要
国民经济的高速发展带来相对不均衡的负荷分配,给电网频率的稳定性带来较大挑战。相对于新能源发电,火电机组具有较强的可控性,在电网调频中需要承担重要作用。伴随着我国新能源发电占比的提升,火电机组所需要承担的电网调频压力逐渐增加。自动发电控制(AGC)辅助服务政策的出台给储能的发展带来了新的机遇和挑战,通过研究分析华中地区某火电机组实际出力情况,比较不同配置储能参与辅助服务给系统带来的效益,给出电源侧储能参与电网调频的最优配置方案。所提出的算法为后续火电机组配备储能参与电网调频辅助服务提供设计参考,有助于提升后续新能源并网消纳。
The rapid development of the national economy has brought relatively unbalanced load distribution,which brings greater challenges to the stability of the grid frequency.Thermal power units have stronger stability than renewable energy,so they need to play a more important role in grid frequency regulation.In addition,with the increase in the proportion of renewable energy power generation in our country,the pressure on the grid frequency adjustment that thermal power units need to bear is gradually increasing.The automatic generation control(AGC)auxiliary service policy has brought new opportunities and challenges to the development of energy storage technologies.This article analyzes the actual output data of a thermal power unit in Central China,the optimal configuration plan for power-side energy storage participating in grid frequency modulation is given by comparing the benefits of different configurations of energy storage participating in auxiliary services.The algorithm proposed in this article provides a design reference for subsequent thermal power units equipped with energy storage to participate in grid frequency modulation auxiliary services,also helps to improve the consumption of renewable energy.
