摘要
该文主要探究微电网负荷平衡优化控制技术在并网、孤网,以及并网转孤网等不同运行状况下的应用效果。首先介绍微电网的整体结构,以及微电网在并网运行、并网转孤网、孤网转并网3种模式下的负荷平衡优化控制策略。随后利用仿真软件Matlab搭建光储混合微电网仿真模型。利用该模型对微电网负荷平衡优化控制技术的应用效果展开仿真分析。结果表明,在并网运行时,大电网与微电网可实现能量双向流动,维持微电网功率平衡;在孤网运行和并转孤时,蓄电池可向微电网提供电压与频率,保证功率平衡和系统稳定运行。
This paper mainly explores the application effect of microgrid load balance optimization control technology in different operating conditions,such as grid connection,isolated grid,and grid connection to solitary grid.Firstly,this paper introduces the overall structure of microgrid and the load balance optimization control strategy of microgrid under three modes:grid-connected operation,grid-connected to isolated grid and isolated grid to grid-connected.Then the simulation model of optical storage hybrid microgrid is built by using the simulation software Matlab.The model is used to simulate and analyze the application effect of microgrid load balance optimization control technology.The results show that when connected to the grid,the large grid and the microgrid can realize two-way energy flow and maintain the power balance of the microgrid,and when the isolated grid is running and paralleling to solitary,the battery can provide voltage and frequency to the microgrid,so as to ensure the power balance and stable operation of the system.
