微电网日前优化调度的研究

Research on the Scheduling of Micro-Grid

摘要: 本文研究的是微电网日前优化调度的问题。要求在蓄电池、可再生能源光伏发电、风机发电及微网与电网交换功率相互协调组合情况下，计算各时段负荷的供电构成、全天总供电费用和平均购电单价。首先对文中附件数据分析，分别建立分时段计算模型、单目标整数规划模型、单目标非线性优化模型；然后结合两位二进制枚举法，利用MATLAB编程，分别求出平均购电单价、全天总供电费用、各时段负荷的供电构成三个分指标；最后通过求解得到的数据进行图像分析，从而得到可再生能源的利用情况。

Abstract: This paper studies the problem of micro-grid optimization. Requirements in the battery, renewable energy photovoltaic power generation, fan power generation and micro-network and power grid exchange power in a coordinated combination of circumstances, calculate the composition of the load of each time, the total power supply costs and the average purchase price. Firstly, the data of the attachment are analyzed, and the time-interval calculation model, the single-objective integer programming model and Single Target Nonlinear Optimization Model are established respectively. Then, combining the two binary enumerations, the three sub-indicators of the average purchase price, the total power supply cost and the load of each period are calculated by MATLAB programming; finally, the image is analyzed by the obtained data, and the utilization of renewable energy is obtained.
