Wind Energy Fed SEPIC Converter with PID Controller for High Performance

As the need for energy rises, the fuel cost for generating power has also increased. To face such problems, renewable energy resources helped a lot by generating power from sun, wind, hydro, etc. In this paper, wind energy is implemented as a source for a Single-ended primary inductor (SEPIC) converter, which is controlled by a PID controller for analyzing the system performance. Depending on the speed of the wind, the energy is produced and the produced AC power is converted into a DC source by a rectifier and then a DC-DC converter is required for a constant output connected to a DC load. To enhance the system performance, a PID-controlled SEPIC converter is employed because of its simpler design, higher gain flexible and non-inverting output. It can be used for many high-range applications. The proposed system is evaluated using Simulink and resulting in increased performance output. For future scope, other modified control techniques can also be added to the system for better output.
