垂直堆叠重力储能系统优化调度与算法建模OA
Optimal Scheduling and Algorithmic Modeling of Vertical Stacking Gravity Energy Storage System
为缓解源荷错配导致的弃电与未满足负荷,以垂直堆叠重力储能系统(VBESS)为对象开展调度建模.建立块体重力势能与充放电效率模型,提出启发式规则,并构建以最小化最大未满足负荷为目标的混合整数线性规划(MILP)模型.基于屋顶光伏与居民负荷实测数据,对比无储能、启发式规则与最优调度.结果表明,MILP在合理塔体规模与初始储能水平下,可显著降低最大未满足负荷与能量浪费,提高新能源利用率与供电可靠性.该方法可为VBESS容量配置与运行策略提供量化依据.
To mitigate renewable curtailment and unmet load caused by source-load mismatch,scheduling modeling of a Vertical Block Energy Storage System(VBESS)is conducted.A gravitational potential energy and charge/discharge efficiency model is developed,a heuristic operating rule is proposed,and a mixed-integer linear programming(MILP)model that minimizes the maximum unmet load is formulated.Using measured rooftop PV and residential load data,three cases-no storage,heuristic control,and optimal scheduling-are compared.Results show that,with a reasonable tower scale and initial energy level,the MILP schedule markedly reduces the maximum unmet load and energy waste,improving renewable utilization and supply reliability.It is concluded that the proposed method provides quantitative guidance for VBESS sizing and operating strategies.
