Prospects and Challenges of Gravity Energy Storage Applications in New Type Power System
摘要
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.关键词
