POWER QUALITY IMPROVEMENT IN DC SYSTEMS USING UPFC-BASED MULTILEVEL CASCADE CONVERTERS
Main Article Content
Abstract
Combination While renewable energy can serve as a decent replacement for traditional energy, integrating it into the grid may provide additional challenges. In a similar vein, wind turbines must produce high-quality electricity in order to maintain the grid's stability and dependability. An increasing number of wind turbines are being linked to the electrical grid in an effort to lessen the negative environmental effects of traditional energy generating. To connect a wind turbine to the grid, one must comprehend how disturbances affect the energy's quality. As stable a voltage and frequency as is practical is required. FACTS devices can be utilisedto achieve this stability. Recently, voltage-source and current-source inverters have been employed to lessen power supply oscillation. Furthermore, a number of them are employed to enhance the wind power generating systems' (WPGS) transient and dynamic stability. Connected to the grid, a wind turbine generates active and reactive energy, voltage sag and swell, flashing and harmonic emissions, and electrical switching behaviour. The reactive power need of a three-phase grid-linked wind-driven induction generator can be modified in a number of ways, including by using UPQC and instantaneous pq theory to account for harmonics created by a non-linear load connected to the PCC. To enhance power quality, the FACTS Device UPQC control mechanism is simulated using MATLAB/SIMULINK.
