Discharging Power Adjustment of Two-Stage Ramp-Type Gravity Energy Storage System for Fast Response to Load Demand
摘要
Abstract
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 traditional ramp into two segments,precise control on discharging power and fast response to load demand can be realized by controlling the releasing heavy blocks quantity on the top stacking yard,the releasing height of the ramp stacking yard and the grab position of heavy blocks on the ramp stacking yard.With Matlab/Simulink,the simulated model of two-stage ramp-type GESS is established,and the correctness and effectiveness of the presented method are verified.The achievement can provide an important reference for the discharging power adjustment and precise control of ramp-type GESS.关键词
