摘要：

我国正在加快构建清洁低碳、安全高效的能源体系，显著的特点就是推动新能源装机快速发展。但随着新能源装机规模的不断增加，其出力的随机波动性给电力系统的功率平衡带来了巨大的调峰压力，也成为制约高比例新能源消纳的主要因素；同时，由于新能源等电力电子设备的弱支撑性，高比例新能源电力系统的安全稳定也面临巨大的挑战。本文结合新能源并网分布特点及其快速增长带来的调节需求，提出了增强电力系统调节能力配置储能的分析原则；结合特高压电网安全运行需求，分析了储能提升特高压电网安全性方面的作用，在受端电网内配置GW级（数百万千瓦）的电化学储能电站，参与电网频率安全控制，能有效应对功率不平衡量的冲击、减少系统频率跌落的幅度、改善频率恢复特性、保障系统的频率稳定性。综合分析表明，推动GW级电化学储能应用，构建更加灵活高效的电力系统，既能有效促进新能源健康发展和高效利用，也可有力保障含高比例新能源和高比例电力电子设备的电力系统的安全稳定运行。电化学储能在电力系统中的试点应用取得了大量经验，为下一步大规模应用奠定了良好的基础。

Abstract:

China is speeding up the construction of a clean, low-carbon, safe and efficient energy system. The remarkable feature is to promote the rapid development of new energy installation. However, with the continuous increase of new energy installation, the random fluctuation of its output has brought huge peak regulation pressure to the power balance, and has become the main factor restricting the high proportion of new energy consumption. At the same time, due to the weak support of power electronic equipment of new energy, the security and stability of high proportion of new energy power system is also facing great challenges. Combined with the characteristics of new energy distribution, as well as the regulation demand brought by its rapid growth, this paper puts forward the analysis principle of enhancing power system regulation capacity and allocating energy storage; Combined with the safe operation requirements of UHV power grid, the role of energy storage in improving the security of UHV power grid is analyzed. The GW level energy storage is configured in the receiving end power grid to participate in the power grid frequency safety control, which can effectively reduce the impact of power imbalance, reduce the amplitude of system frequency drop, improve the frequency recovery characteristics, and ensure the frequency stability of the system. Comprehensive analysis shows that promoting the application of GW level electrochemical energy storage and building a more flexible and efficient power system can not only effectively promote the healthy development and efficient utilization of new energy, but also effectively guarantee the safe and stable operation of the power system with high proportion of new energy and high proportion of power electronic equipment. The pilot application of electrochemical energy storage in power system has gained a lot of experience, which lays a good foundation for the next large-scale application.
