摘　　要：考虑到微电网中的风力发电、光伏发电等可再生能源发电单元所具有的波动性、随机性使得微电网系统运行的能力相对较弱,提出一种计及储能装置平抑风光功率波动的微电网系统优化运行模型。模型以微电网的经济环保运行为目标函数,将储能装置平抑风光功率波动的数学模型作为约束条件,储能装置的充放电功率根据风光实时输出功率及其容量值确定。然后以确定的微电网系统为研究实例,利用改进的微分进化算法求解得到微电网内各分布式电源的最优输出功率,从而实现微电网的经济运行。最后验证所建立模型的合理性。A micro-grid system optimal operation model considering energy storage system used to smooth the wind turbine and photovohaic power fluctuation has been put forward. The economic operation of micro-grid is treated as objective function, the mathematical model for stabilizing power fluctuations based on energy storage device is treated as constraint condition. The charge and discharge power of energy storage device is determined by real-time power output and capacity of photovoltaic and wind energy system. The optimal output power of distributed power supply within the micro-grid has been achieved using the improved differential evolution algorithm based on established micro-grid system in this study. The rationality of the model is verified through the case analysis.
