【摘要】：目前,国内外对微网运行的能量管理研究已取得了一定的成果,但是,主要是针对并网型微网运行的研究,而对孤岛型微网能量管理的研究还相对较少。因此,针对孤岛型微网的运行特点,研究了微网中的需求侧管理与调度方法,建立了孤岛型微网能量管理的优化调度模型。首先分析了在微网中开展需求侧管理的意义,将微网内的负荷按重要程度和用电特性分为三类,并作为可调度的对象。其次以总运行费用与停电损失之和最小为目标,计及停电量约束、储能设备运行约束和备用容量约束等条件,建立了孤岛型微网能量管理的混合整数规划模型,并使用CPLEX软件进行求解。算例结果表明,引入需求侧管理增加了孤岛型微网能量管理的灵活性,提高了可再生能源发电的利用率,降低了微网的运行成本。
[Abstract]:At present, some achievements have been made in the research of energy management in microgrid operation at home and abroad, but the research is mainly aimed at grid-connected microgrid operation, but the research on energy management of isolated microgrid is relatively rare. According to the operation characteristics of islanding microgrid, the demand-side management and scheduling method in microgrid is studied, and the optimal scheduling model of islanding micro-grid energy management is established. Firstly, the significance of demand-side management in microgrid is analyzed. The load in the microgrid is divided into three categories according to the importance degree and the characteristics of power consumption, and it is regarded as the schedulable object. Secondly, the minimum sum of the total operation cost and the power loss is taken as the goal, and the constraint of the power outage is taken into account. A mixed integer programming model for energy management of isolated island microgrids is established under the conditions of operating constraints and reserve capacity constraints of energy storage equipment. The model is solved by using CPLEX software. The introduction of demand-side management can increase the flexibility of energy management of isolated microgrid, improve the utilization rate of renewable energy generation, and reduce the operation cost of microgrid.
