Discharging Power Adjustment of Two-Stage Ramp-Type Gravity Energy Storage System for Fast Response to Load Demand
斜坡式重力储能系统(GESS)放电时通常将上堆场重物块运送至下堆场.然而,当放电过程中系统负荷需求出现波动时,现有方案难以通过及时调整重物块数量来调节输出功率,导致重力储能系统响应不及时并造成额外能量损耗.通过在斜坡两侧增加辅助堆场并将斜坡分为两段,通过控制顶部堆场重物块释放数量、斜坡堆场释放高度以及斜坡堆场重物块抓取位置,实现了重力储能系统输出功率的精确控制与负荷需求的快速响应.基于Matlab/Simulink平台搭建了两段式斜坡重力储能系统…查看全部>>
Generally,discharging conditions of ramp-type gravity energy storage system(GESS)can be realized by transporting heavy blocks from the upper stacking yard to the lower one.However,the number of heavy blocks may not be adjusted timely when load demand fluctuates during discharging process,which may cause the delayed response and additional energy loss of GESS.By configuring auxiliary heavy blocks stacking yards on both sides of the ramp rail and dividing the …查看全部>>
