    摘要:

    随着大量的分布式能源与充电桩接入微电网,使得微电网的能量流动变得复杂多变,这直接影响了能量的利用效率。对此,本文提出了一种针对含有光伏、储能、充电桩的交直流微电网的能量管理系统的控制策略,不仅能够使系统安全稳定可靠运行,还可以将微电网的能量进行合理的分配。针对含有光储充的交直流微电网搭建了一个MATLAB/Simulink仿真模型,采用MPPT策略使光伏列阵输出能量最大;应用储能电池让系统的能量合理分配,对系统能量进行管理;搭建了功率为120kW的充电桩进行充电模式切换的模拟。通过建立模型并采用PXI实时仿真机对仿真结果验证了原理分析的正确性与该控制策略的可行性。

    Abstract:

    With the integration of a large number of distributed energy and charging piles into microgrids, the energy flow in microgrids becomes complex and variable, which directly affects the efficiency of energy utilization. This paper presents a control strategy for the energy management system of AC/DC microgrid with photovoltaic, energy storage and charging piles, which can not only make the system run safely, stably, and reliably, but also distribute the energy of microgrid reasonably. A MATLAB/Simulink simulation model has been built for AC/DC microgrid with optical storage, and MPPT strategy was adopted to maximize the output energy of photovoltaic array. The energy storage battery was used to distribute the system energy reasonably and manage the system energy; A charging pile with a power of 120kW was built to simulate the switching of charging modes. The correctness of the principle analysis and the feasibility of the control strategy were verified by establishing a model and using PXI real-time simulation machine to verify the simulation results.
