Description
Summary:The power supply drops dramatically when a malfunction occurs in a Grid-Connected Wind Energy System (GCWES) system, causing a fluctuation in the voltage level. Switching converters and network components suffer from failures as a result of more distortions in the supply waveform. WES also comprise the majority of today’s energy systems, therefore isolating them during Power Quality (PQ) issues namely voltage sag, short circuit, swell, etc. is no longer a choice. The PQ issues in the proposed system, such as various 3-phase faults and harmonics, are improved in this article by incorporating Wind Energy System (WES)-based Dynamic Voltage Restorer (DVR). The DVR control scheme hybrid of conventional PWM technology for generating reference current and a traditional Proportional and Integral (PI) attached with each element is presented. The primary objective of the proposed configuration is to analyze GCWES performance under a variety of three-phase failure conditions. Also, real and Reactive power, rotor speed, and stator current behavior during various faults are investigated. In this study, the results of the Total Harmonic Distortion (THD) ordinary controller are compared with a proposed controller which shows that the THD% has decreased immensely.
