Hardware in the Loop Simulation on the Operation Control of Microgrid Based on RT-LAB

doi:10.11985/2019.04.013

Abstract

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
