摘要

重力储能技术由于具有本质安全、选址及容量配置灵活、可深充深放、无充放电次数限制、可规模化开发等突出优势，可在含高比例新能源新型电力系统的功率波动平滑、削峰填谷等方面发挥重要作用。该文首先概述重力储能技术类型及其发展现状，随后建立重力储能系统的通用充放电模型，并进行系统充放电功率特性分析。在此基础之上，根据重力储能技术特征及其系统并网需求，提出两种可行重力储能系统并网方案，并基于一个实际工程应用场景进行相应的充放电运行仿真分析。最后，对重力储能技术在新型电力系统中的应用前景及技术挑战进行展望。该文工作可为未来重力储能技术在新型电力系统应用的深入研究及工程应用提供借鉴与参考。

Abstract

Gravity energy storage system (GESS) can play an important role in smoothing power fluctuation and shaving peak-valley load for new type power systems with high proportion of renewable energy sources

due to its outstanding advantages such as inherent safe characteristic

flexibility in location for installation and capacity configuration

capability of charge and discharge in depth

no limit of charge and discharge times

and capability for application in larger scale

etc. In this paper

the types and development status of GESS are summarized first. Then

a universal charging and discharging model of GESS is established

and the charging and discharging power characteristics of GESS are analyzed. On this basis

according to the characteristics of GESS and its grid connection requirements

two feasible schemes for grid connection of GESS are proposed

and the charging and discharging operation simulations of corresponding two schemes are carried out based on a practical engineering application scenario. Finally

the application prospects and technical challenges of GESS in new type power system are presented. This paper can provide references for further research and engineering application of GESS technology in new type power system.
