摘　　要：针对单一时间尺度下光储容量配置冗余或不足的缺点,考虑孤岛直流微网的供电可靠性指标,结合储能的动态运行特点及约束,基于典型负载曲线与光伏发电曲线,建立了双时间尺度光储容量配置模型。其中,储能系统建模提出了固定–移动储能混合储能模型,以应对短时间内光伏负载波动造成的电力缺口。仿真算例采用改进粒子群算法进行求解,结果验证了混合储能和双时间尺度的优越性,说明了容量配置模型的正确性与配置方案的可行性,可为孤岛直流系统光储容量配置提供参考。In view of the disadvantages of redundant or insufficient optical storage capacity configuration in a single time scale,a dual-timescale based capacity configuration model was established according to the typical data of photovoltaics and loads.The dynamic operation characteristics and constraints of energy storage as well as the power supply reliability of isolated DC microgrids were taken into consideration.Moreover,a mixed stationary-mobile energy storage model was proposed to deal with power shortage issue caused by network fluctuations.Improved particle swarm optimization was applied in simulation example for solving,and result proved the superiority of the mixed storage model and dual timescale analysis.Moreover,the feasibility of the capacity configuration model was confirmed,which can provide a reference for photovoltaic and energy storage capacity allocation.
