Comparative Study on Several PQ and V/f Controller Models in Micro-Grid

Abstract:

Many references have been focused on PQ controllers and V/f controllers, but there are some models with different components share the same control strategy. These models have different simulation results of their own. In this paper, two ordinary PQ controllers and two ordinary V/f controllers have been chosen to study the simulation results of them by Matlab/Simulink. By analyzing voltage and current waveforms of load, it has been decided which PQ controller has result which contains less unbalanced current and less harmonics, and so it is with the V/f controllers. Then the chosen controllers have been applied to an example of Master-slave control strategy for a simple micro-grid, which furthermore proves the dynamic quality of the chosen models. In this way, the problem to choose better models is solved.
