Effective Evaluation Technique For Using A Photovoltaic System Based On A Fly-Back Converter To Improve Power Quality

Abstract

In this modern period, the need for power generation is increasing fast, and to supply the consumer's demand for power, voltage harvested from diverse renewable energy sources must be managed.  Many solutions have been developed with the assistance of various theories and methodologies to raise and maintain the consistent output voltage. However, raising the voltage causes fluctuation and waves at the output during operation, increasing the cost of all equipment as well as maintenance.  The proposed model is implemented with the intelligent control MPPT approach, which allows the controller to respond faster. The Fractional open-circuit voltage controller utilizes in harvesting the maximum amount of energy, despite being impacted by external factors. In terms of architecture and performance, fly-back converters are similar to booster conversions. It comprises an inductor similar to the primary winding of a transformer, and the secondary giving the output is another inductor similar to the secondary winding of a transformer. As a result, the fly-back converter is a power supply design that includes a mutually coupled inductor that stores energy as current travels through it and releases it when power is removed. This methodology is used by the fractional open circuit voltage-based tracking algorithm to provide maximum power point tracking. The input voltage of the converter, which is the same as the solar panel terminal voltage, is maintained at times its open circuit voltage with the aid of power converter modules. It makes use of a two-stage inverter, which is an open-loop circuit that converts the converter's DC output to AC voltage. As a result, the voltage created from the model has a sinusoidal waveform with decreased harmonics, which is obtained by using a low pass filter and then applied to the load.
