摘　　要：微电网是一种新能源系统,整合了分布式发电、储能装置和负载。基于微电网的具体应用情况,针对不同条件和考虑不同因素建立了适用的日前调度模型。这些模型采用了大数据处理方法,考虑蓄电池充电功率、微电网与主网的能量交换等约束条件,建立了微电网的经济评估预测模型。在此基础上,引入了可再生能源供电量作为新的变量,并将定值约束替换为范围约束。以最小化平均负荷的供电单价为目标,建立了不计储能的功率宽约束最优日前调度模型。此外,考虑蓄电池的荷电状态、使用寿命等因素,建立了考虑储能和功率交换约束的最优日前调度模型。针对其他不同的条件,建立了相应的模型,并分析了优化后的调度方案在各个方面的综合表现情况。通过这些模型,可以更好地理解微电网系统的运行情况,并为实际应用提供有益的指导和决策支持。A microgrid is a new energy system that integrates distributed generation,energy storage devices and loads.Based on the specific application situation of microgrid,this paper establishes a suitable front-forward dispatching model based on different conditions and considering different factors.These models adopt the big data processing method,and establish the economic evaluation and prediction model of the microgrid by considering the constraints of the battery charging power and the energy exchange between the microgrid and the main grid.Furthermore,the renewable energy supply is introduced as a new variable,and the fixed value constraint is replaced with the range constraint.The goal is to minimize the power supply unit price of the average load,and to establish the optimal day-ahead scheduling model of power width constraint without energy storage.In addition,the charge state and service life of the battery are also considered,and the optimal day-ahead scheduling model considering the energy storage and power exchange constraints is established.For other different conditions,the corresponding models are established,and the comprehensive performance of the optimized scheduling scheme in various aspects is analyzed.Through these models,we can better understand the operation of the microgrid system,and provide useful guidance and decision support for practical applications.
