Power quality improvement in RDS using smart DSTATCOM

This Paper Simulates the SVC (Static VAR Compensator) and DSTATCOM (Distribution Static Synchronous Compensator) for 4 Bus Radial distribution systems (RDS) to improve voltage stability with higher precision, smaller overshoot and robustness with improved performance. The results are compared with Adaptive Neuro-Fuzzy Inference System (ANFIS) Controller for the effectiveness. Finally, developed a prototype of 4 bus Radial Distribution System (RDS) with shunt connected Distribution Static Synchronous Compensator (DSTATCOM) capable of voltage regulation with Digital Signal Processor TMS320F2812. With the contribution of intelligent operation and Digital control implementation in the RDS, The complexities envisaged by integrating FACTS during smart grid transformation are simplified. Thus, Power quality (PQ) problems like reducing the reactive power and non-linearities such as voltages sags and waveform deformations caused by load fluctuations and harmonics effectively.
