摘　　要：为平滑基于卷扬提升机的重力储能系统中多重物切换导致功率的间歇性和波动性,提出了以重力储能为主、飞轮储能为辅的综合物理储能系统设计和控制策略。首先对重力储能系统和飞轮储能系统的工作原理、控制方法以及电动/发电机和变流器等关键部件进行分析,构建了重力储能和飞轮储能电机并网系统模型;然后仿真两种储能系统在充电、待机和放电工况下,机侧和网侧的相电压、相电流等参数的变化;最后建立了综合物理储能系统的仿真模型,并开展了两种储能系统匹配运行特性的研究,设计了综合储能系统的能量管理和控制策略,并对其在不同运行工况下的运行特性进行仿真研究,验证了综合物理储能系统结构和控制策略的可行性。This study proposed an integrated physical energy storage system design and control strategy with gravity energy storage as the main and flywheel energy storage as an auxiliary to smooth the fluctuation and intermittency of discharge caused by multi-weight switching in a gravitational energy storage system based on a skip hoist.First,the study evaluates the working principle,control methods of gravitational energy storage system and flywheel energy storage system,and critical components,such as motor/generator and converter,and further constructs gravitational and flywheel energy storage motor grid-connected system model.Then,the study simulates and analyzes the variation of parameters including the phase voltage and phase current on the machine side and network side of two kinds of energy storage system at charge:stand-by and grid-connected stages.Finally,the study constructs the simulation model of the integrated physical energy storage system,carries out the research on the matching operation characteristics of the two energy storage systems,designs the energy management and control strategy of the integrated energy storage system,and simulates its operating characteristics at different operating stages to verify the feasibility of the structure and control strategy of the integrated physical energy storage system.
