Abstract:
This study considers the frequency control of isolated microgrids. The microgrid under investigation involves a programmable generator and a constant-speed horizontal-axis wind turbine that generate power in varying wind-speeds. In addition load is variable. Moreover, the plug-in hybrid electrical vehicles are used as energy storage system with grid connected capacity (V2G). These vehicles depending on their charging status can act like batteries and inject power to the grid, or consume power like predictable loads.
In this study, frequency control of the microgrid is performed on both primary and secondary levels, each of them use model predictive controller (MPC). The results of this method is compared against the classic PID controllers. The innovative aspect of this work is in utilizing a dynamic model for the mechanical and electrical parts of the wind turbine, in addition to its aerodynamic parts. The frequency-control results obtained by using a full dynamic model for the wind turbine generator are also evaluated.
