摘要
储能装置在微电网中发挥着不可替代的作用,在微电网中有很大的市场应用前景。文中在配置储能容量时考虑风电机组与光伏机组的可靠性,采用序贯蒙特卡洛法模拟风电机组、光伏机组的正常运行、故障概率;对于蓄电池与超级电容器具有优势互补的特点,利用离散傅里叶变换法对一个周期内的不平衡功率进行频谱分析,建立规划周期内综合费用最小为目标的配置模型,确定混合储能的最佳容量。算例分析表明,当考虑风电机组与光伏机组可靠性时,混合储能配置的额定容量大于不考虑可靠性时的额定容量,为进一步研究微电网的储能规划提供借鉴。
Energy storage device plays an irreplaceable role in micro-grid and has a great market application prospect in micro-grid.This paper considers the reliability of wind turbines and photovoltaic units when configuring energy storage capacity and adopts the sequential Monte Carlo method to simulate the normal operation and outage probability of wind turbines and photovoltaic units.In view of the complementary advantages of battery storage and super-capacitor storage,discrete Fourier transform(DFT)is used for the spectral analysis of unbalanced power during a period.The optimization model with the goal of minimizing comprehensive cost is established in the planning cycle,and the optimal capacity for hybrid energy storage is determined.The calculation example analysis shows that when considering the reliability of wind turbines and photovoltaic units,the rated capacity of hybrid energy storage configuration is greater than the result of not considering the reliability,which provides reference for further research on energy storage planning of micro-grid.
