摘要

针对垂直式重力储能系统在规模扩展过程中存在规模扩展方式受限以及多载台循环运行条件下系统功率特性尚不清晰的问题，提出一种单井道结构垂直循环式直线电机重力储能系统。首先，介绍系统拓扑结构和工作原理，描述系统多种运行方式，阐明载台循环复用、重物数量调节和载台错峰发车对系统扩容及功率调节的作用机理。其次，通过错峰发车时序模型将批次内时移叠加和批次间循环复用统一描述，建立多载台循环运行条件下的系统功率模型。最后，结合MATLAB/Simulink构建联合仿真模型，在最小安全间距约束下分析批次配置变化对系统储能规模与输出能力的调节作用，并进一步研究启动相位参数对系统功率波动的影响。结果表明：在设定参数及最小安全间距约束下，改变系统在运重物数量可实现系统平均功率的离散调节；在不同批次配置下，调节批次内载台错峰发车程度可有效降低系统功率波动，提高系统功率平稳性，储能模式系统峰谷差和功率标准差最大降幅分别为83.2%和85.6%；释能模式系统峰谷差和功率标准差最大降幅分别约99.1%和99.0%。

Abstract

Vertical gravity energy storage systems suffer from limited scalability

and their power characteristics under multi-carrier-platform cyclic operation are ambiguous. To address these issues

this study proposes a linear-motor-based single-shaft vertical circulating gravity energy storage system. This study first introduced the system topology

operating principle

and multiple operating modes of the proposed system. Next

the action mechanisms of carrier-platform cyclic reuse

adjustment of the number of in-service heavy masses

and staggered carrier-platform dispatch in relation to the system capacity expansion and power regulation were elucidated. Subsequently

a staggered-dispatch timing-sequence model was adopted to generate a unified description of intra-batch time-shift superposition and inter-batch cyclic reuse. Based on this description

a system-level power model with multi-carrier-platform cyclic operation was developed. Finally

a MATLAB/Simulink-based co-simulation model was constructed to analyze how batch-configuration variation regulates system energy storage capacity and output capability under the minimum safe-spacing constraint. Additionally

the model was used to examine the influence of start-up phase parameters on system power fluctuations. The results showed that under the minimum safe-spacing constraint

the system average power can be regulated discretely by adjusting the number of in-service heavy masses. Furthermore

under the parameter settings adopted in this study and across different batch configurations

system power fluctuations can be reduced and power stability regulation improved by appropriately regulating the degree of intra-batch staggered dispatch. In the energy storage mode

the system peak-to-valley difference and power standard deviation decreased by up to approximately 83.2% and 85.6%

respectively. In the energy release mode

the corresponding maximum decreased to approximately 99.1% and 99.0%

respectively.
