Performance Comparison of SRF-PLL and STF Control Algorithm for Power Quality Improvement
Abstract: Electrical power distribution system power quality improvement is a major issue. Controlling grid connected converters (GCCs) in adverse grid conditions is also a challenge. This condition cannot be ignored due to rapid growth in the use of inverter-interfaced renewable power generation sources and non-linear loads. The SRF (Synchronous reference frame)- PLL (Phase-locked loop) and extended self-tuning filter are simulated and compared under distributed power generation for mitigation of harmonics, reactive …
