摘要:

近年来,包含风光燃等多种分布式电源的微电网得到快速发展,风光发电具有波动性、不确定性,且微电网可根据实际情况并网或孤岛运行,加大了微电网稳定、安全运行的难度。在RT-LAB中搭建了微电网仿真模型,在LabVIEW中编写一种以功率平衡为基础、保证电网运行方式平滑切换的运行控制策略,利用RT-LAB和PXI搭建了硬件在环平台,并对多种典型情况进行了仿真,仿真结果表明了搭建模型的正确性以及所提策略的有效性,为电力建设前期分析、设计提供了有效的仿真手段。

Abstract:

In recent years, the micro-grid which including wind, solar, gas, and so on has developed rapidly. Wind and solar power generation is volatile and uncertain, and the microgrid can be connected to the grid or run on an island according to the actual situation, which increases the difficulty of stable and safe operation of the microgrid. A simulation model of microgrid is built in RT-LAB. A running control strategy based on power balance and smooth switching of power grid operation is written in LabVIEW. The hardware in the ring platform is built with RT-LAB and PXI, and several typical cases are simulated. The simulation results show the correctness of the model. As well as the effectiveness of the proposed strategy, it provides an effective simulation tool for analysis and design of power construction.

Key words: Microgrid, operation control, hardware in the loop
