Active harmonic filters
APF can reduce some types of power quality disturbances such as harmonics, reactive power, and unbalanced load currents. The APF uses fast switching solidstate devices and GTO emerging as a viable in smart grid applications, battery charging scheme battery storage system. Smart grid uses distributed-STATCOM (D-STATCOM) for energy efficiency, energy saving, loss reduction, and power factor enhancement. The chapter presents different APF topology with modified control application and case studies for smart grid and renewable energy utilization. New emerging application for APFs in campus intelligent met heuristic optimization and search algorithm for optimal PWM using symmetrical, a symmetrical, inverse sine carrier, and optimum point on wave switching strategy with online search to minimize dominating harmonic and THD at the point of interface with the AC smart grid.
