In this paper, an independent wind energy conversion system is studied with the control strategies used to provide power specifically to areas far from the grid. In this research, three strategies are designed and used in order to stabilize the output. This system contains a directed rectifier which is responsible for maximum power point tracking. Also, a common DC bus and a fully controlled inverter are designed. An LC filter is also used in the system in order to eliminate switching harmonics to a considerable extent and provide a reliable noiseless source for load supply. Since the power demand and the produced power of the turbine are variable and indistinguishable in each moment, a depletion load is also placed in the system. In this study, it is observed that the designed strategies prove the output stability in different sections and under different conditions with resonators and non-linear PI and PID controllers. The designed strategies also supported by the simulation results.
